So in a certain sense , the use of solvent-based paints historic water-based paint so far distant . Water-based paint is the easiest lime emulsion , about a hundred years ago that it was planning to join emulsified linseed oil which make improvements , this is probably the first latex paint.
History of the development of China's coating
In 1949, the founding of New China , the land of China after years of war , undone . Although China in 480 BC mastered painting techniques, but until 1948 , only about 50 of paint , lack of annual tons, only a few dozen types of paint products , and low-grade varieties are engaged in the production of coatings Staff only 1055 people, which is the basis for the development of new Chinese coatings industry . Paint production in the new China was founded , every 10 years , including the annual average production rate of approximately 200% increase .
1960s, because of the impact of the 1958 Great Leap Forward , the national economy was severely damaged, the housing problems of urban residents was seriously affected , housing difficulties become a prominent issue. At reduced cost, reduce the amount of cement steel case , the formation of a number of iconic residential type with period features simple floor , bamboo floor, tendons , and other Tongzilou living quality of the residents down to the limit.
1970s, after the Cultural Revolution , the country experienced a decade shackles of residential construction under almost stagnant situation . Taking Beijing as a representative , residential construction began to try to use high-rise residential construction technology of production in large quantities .
Early 1970s, Shanghai , Beijing , Tianjin, Guangzhou and Gansu have been carried out styrene acrylate latex , vinyl acetate, acrylic latex paint research and pure acrylic latex paint , and in the mid-1970s into small batch production. Then paint remaining in storage , water resistance , stain resistance is poor and other issues, and the construction is also being explored . Although a small amount of paint used to promote the use of the building's exterior has been carried out , but to spread the broad , mainstream was still oily architectural coatings.
Shanghai Institute of Architectural Science developed the first successful water glass interior paint polyvinyl alcohol , polyvinyl formaldehyde glue successfully applied Beijing hotel renovation . In 1979, B thick acrylic emulsion paint in Beijing successfully developed. Late 1970s, chlorinated rubber paint solvent in Shanghai , Guangzhou and other places refers to the production and application . At this time, the building has been gradually used in the decoration of the paint and start tier metropolitan markets .
1980s, more attention -scale residential construction and the environment , focusing more on a combination of diverse groups form . People in the pursuit of a better living environment , while also began to spread the concept of decoration , interior towns developed slowly . At this point , interior paint brush , wall scraping sand or inlaid tiles , concrete paving quite common, interior paneling and floor paint decoration is the pursuit of economic conditions of the family .Sellotape
80s to 106 coating and modified polyvinyl alcohol polyvinyl formal architectural coatings 107 coating is a water soluble film forming materials made of rage , and now there are still a large market share .
In 1984, Jiangsu Province Institute of Building Materials Industry developed a colorful paint . In 1984, Zhejiang Institute of Zheng Jiabao hair had JB240 scrub interior paint , also known as water-based resin paint. Faster development time and slowly in the architectural coatings applied to the common people, but also the sudden emergence of functional coatings , fire retardant paint , waterproof paint , mildew paint , moisture coatings, paints and other signs slowly develop, China's paint industry began to be fully development.
1990s, " people-centered " collective well-off residents of the residential community living environment , housing type, and property management has become typical of this era. This type of housing is from the living room, entry vestibule, storage space , kitchen sets and other public and private partitions showing , wet and dry area , static and dynamic partitioning and other functional decoration features. This makes urban residents for more extensive application of architectural coatings and subdivision.
Early 1990s , colorful interior paint swept the market , the so-called colorful paint is added to the water of various colored oil paint , the so-called " oil in water " and later technological development , but also a " water- water" colorful paint . But with synthetic resin coating to enter the market , and colorful paint has become history ; mid-1990s , an acrylic polymer membrane material for the interior and exterior latex paint gradually started to become mainstream architectural coatings market.
In 1990 , to address the problem of architectural coatings crack , Beijing Red Lion Coatings successful research and production of elastomeric architectural coatings market . Colorful paint at this time with its unique decorative effect rage. Early 1990s , China's paint industry formed a production capacity of 10,000 tons and consumer markets. 1995 , gradually regain latex interior paint market , colorful paint rapid cooling . In addition, melamine paint, Tan velvet coating , imitation granite paint have begun to enter the construction market .
China entered the era of commercial housing . Scenario house facade in dealing with a diversity of each change , the use of simple materials to get the enjoyment of beauty ; in the fine details of the deal done and customization of the goal, almost reached the level of perfection .
2010 output reached 9.666 million tons China Coating , an increase of 22.8% . Among them, the architectural coatings total production of about 3.519 million tons , an increase of 23.7% , six times in 2001 .
In addition to 2001 , the annual growth rate of China's architectural coatings were more than 10% , in 2008 to 2010 , architectural coatings production for three consecutive years the annual growth rate is over 20% . 2010 construction volume of 2.6 kilograms per capita use of coatings , architectural coatings using urban per capita is 5.5 kg , respectively, in 2001 six times, four times . Urban per capita use of architectural coatings architectural coatings faster than the growth rate of per capita .Washi tape
2013 China coatings industry output reached 13,033,490 tons , an increase of 3.58 percent , by leaps and bounds for the Chinese coatings industry has attracted the attention of the world , from a less compelling small industry has developed into a thriving sunrise industry.
Today , China's annual production of about 1.2 million tons of architectural coatings to 130 million tons, of which 30 % to 40% for the low water solubility of architectural coatings . Thousands of architectural coatings manufacturer , to reach an annual output of 5,000 tons of business less than 3 %. Household paints market entities controlled by the state legislature , ICI -owned companies and other multinational companies in China , the production of latex paint two group companies accounting for total output 700,000 tons of latex paint nearly 1 /3. Recalling the history of the development of China's 50 years of architectural coatings , architectural coatings can be found from the early development of inorganic to organic , organic and inorganic composite coating direction , developed from solvent-based paints to water-based paint in the direction from thin to thick qualitative nature, from single development in the direction of multi-layer coatings. This is the development direction of foreign architectural coatings is - consistent , but also synchronized.
Three historical stage of development
Paint has experienced day paint film material used to form the coatings industry and the production of synthetic resin paints three historical stages of development.
The first stage of the development of paint coatings day film-forming substances country in the world to use day to use the membrane material ─ ─ lacquer coating paint often said National excised greaseproof paper sealed with lacquer lacquer species use sumac . There are days lacquer paint lacquer will touch people allergic skin allergies and some even fewer people will smell the paint smell rash and large paint brush technical requirements are also high on the lacquer is now common.
Coatings industry during the formative stages of the second phase of linseed oil , a large number of mature oil production and application of varnishes and paints to promote the rapid development of the coatings industry early varieties produce pigment when transferred to a drying oil paint -like construction to go through the deployment and diluted to the proper viscosity and easy to use paint factory direct coating formulation suitable for the construction requirements that blending paint .
Most of the paint before the nineties are blending paint shortcomings taste great but slow drying ; advantage of good weather construction is easy blending paint pollution is mainly due to the use of solvents and solvent containing VOC, toluene, xylene, heavy metals and other pollutants.Masking tape
With the advancement in science and technology continue to emerge out of a variety of synthetic resin coating production development of new synthetic membrane material that historical period during which existing coatings have thousands of brands and some special role in the anti- nuclear radiation fireproof coating paint coatings, anti-infrared camouflage paint says everything.
Now paint coatings industry are moving towards a new phase to save resources, energy and environmental protection, ecological balance in favor of the direction of development , such as water-based paints, paint special features appear .
To the development of environmentally friendly paint
From the mid- 1930s began , Germany began to polyvinyl alcohol as a protective plastic polyvinyl acetate emulsion used as a paint color development . By the 1950s , pure acrylic emulsion in Europe and the United States have limited sales , but because the price is expensive, there is not much to increase its production .
Into the 1960s, all development in the emulsion , the most prominent is ethylene vinyl acetate , vinyl acetate ethylene copolymer with higher fatty acids have also been developed , production has increased.
Since the 1970s, due to the strengthening of environmental law and people's environmental awareness developed countries to limit emissions of organic solvents and hazardous substances , so that the use of paint, subject to various restrictions . 75% of the raw materials from petrochemical manufacture of paint , because the economic crisis in the Western industrial countries and the third world countries due to oil price adjustments in the world, the universal demand to save energy and conserve resources. For these reasons, water-based paint , especially latex paint instead of oil products as more and more people 's attention. Preparation of water-based paint technology advances quickly, especially emulsion synthesis technology advances faster.
7080 's as a representative of contemporary water-based paint - paint has been some development, but to promote the application has entered the trough. To paint the country's popular interior paint and price competition , the result is ruin, and even being denied a considerable part of Builders and decoration, while the rage tile exterior latex paint again claimed more than half of the market . Since the 1990s , not only greatly improve the performance of paint quality , the price is also slowly being accepted , especially in the large multi-national paint company Netherlands, Japan headed into China's market , really opened a new chapter of modern water-based coatings.Wholesale masking tape
