Foreign prospects for exterior wall coatings

According to analysis and statistics, the development trend of coatings is mainly the following three points:
The development of water -based development
The world coating variety structures to reduce VOC and other directions. Water -based coatings are one of the direction of development. The proportion of traditional solvent -based coatings in China has gradually decreased, and the development rate of water -based coatings is also rapid, but low -end varieties of polyvinyl alcohols still account for a large proportion. Improve the quality of water -based coatings and develop new varieties is an important part of consolidating and developing water -based coatings.
The key research and development should be based on the latex coatings of the acetate-acrylic syncis, lyre-acrylic clustering, and pure acrylic acid series, and strive for durability, paint film smoothness, plumpness, plumpness, plumpness, plumpness, plumpness, plumpness, plumpness, plumpness, plumpness, fullness, and fullness, plumpness, and fullness, plumpness, and fullness, plumpness, and fullness, plumpness, and fullness of paint film. Construction and decorativeness have made breakthroughs; the water -based base materials of more mature epoxy emulsion and water -based polyurethane should continue to study high -performance water -based coatings to meet the special requirements of some of them.
The development of high -performance and high -grade
The ideal performance of coatings must not only protect and beautify the substrate, but also give the substrate itself special features. The coatings can obtain very amazing high -performance, high value -added, and advanced effects, such as high weather -resistant fluoropolytic coatings, which are used for good results for building.
Thefluoro resin coatings have excellent weather resistance, durability, and chemical resistance compared to other synthetic resins. However, fluorine resin is more expensive and is used for the exterior wall of the building to be greatly limited. Pay attention to the development of fluorine resin in water -based development, especially the co -vermary emulsion with fluorine resin modified with fluoroethylene as the main body, making it a high -quality base material that has good performance, high grades, prices and acceptance of people. Develop high -performance coatings to lay the foundation.
The research on water -based polyurethane coatings should focus on developing products. Polyurethane is one of the high -end materials with excellent performance, which makes it hydrated, not only meets the requirements of reducing pollution and saving energy, but also maintains the characteristics of polyurethane itself.
This -oriented development
In addition to the existing quality levels such as fire prevention, anti -virus, prevention, insecticidal, insulation and insulation, etc. Steady research and solving difficulties and new problems in architectural decoration. Compound technology will be an effective way to improve and meet various functions.
The UK developed a coating of anti -paint [3], which can be brushed on the wall that may be painted. When painting with paint, ink, etc., the chemical ingredients in the paint can prevent them from drying and adhesion. The paint with strong stickiness will be “disintegrated”. This kind of anti -coating paint is low in price and is convenient to use. Japan also produces car coatings that are not afraid of rubbing, scraping, and scraping. It is durable, bright, and not vulnerable. The owner of the car does not have to worry about the car’s beautiful appearance.
The discoloration coatings that have been successfully made in the development of “smart coatings” that can change with temperature changes. If it is painted on the top of the building, it becomes black in cold days and absorbs calories; when it is hot, it becomes white and reflects the sun. This coating contains several organic compounds, which can be reversed to the color at room temperature or room temperature. There are several smart coatings such as red, blue, green, black and orange. There is also a kind of temperature coating that indicates the surface temperature and distribution of the body surface with the appearance color. It can measure the surface temperature and distribution of general instruments such as operating surfaces, large -scale surfaces, etc.
The Dutch chemist uses a polymer coating to harden Europe. The treated cork can be durable like tropical hardwood. The United States has made major progress in developing ultra -hard coating materials. There is a type of coating theory that the hardness is more than diamond. It is a very promising coating material. The pure inorganic coatings developed in Japan have the performance of heat resistance, corrosion resistance, abrasion resistance and high hardness.
Australia launched a building material coating that can be sprayed on any smooth plate, brick body, and cement to replace asbestos. You can also change the composition of the paint as needed, and the frog stone contained in it is harmless to the environment. If this fire -resistant coating suffers from the fire, it can be discarded like ordinary building materials.
Sweden develops a coating that can effectively absorb multiple odors. When absorbing the smell in the air, it can stabilize the humidity of the air, make it clean and pleasant, and release substances that can sterilize, prevent and fitness. Essence This coating not only improves the environment of public places for people, but also changes the environment of housing, especially smokers.
