Exterior wall coating in the future development direction, really stone paint is on the last

In today's industrial technology development is the main trend towards '8' e, namely on the so-called '8 e' research and development, is mainly refers to the quality of the coating, convenient construction, resource conservation, energy conservation and environmental protection. Therefore, all kinds of paint is water-based, highly solid differentiation and without solvent. The development of architectural coatings is no exception. General requirements is high performance and low pollution. The development direction of Chinese architectural coatings should be to further promote and popularize weatherability excellent architectural coatings, the development of high performance exterior wall coating. High performance refers to the high weatherability, dirt resistance and high color retention, conform to the development direction of energy conservation and environmental protection. At the same time, the development of the decorative and functional characteristics of new functional architectural coatings and related new resin. ( 1) High performance exterior wall coating acrylic copolymer emulsion exterior wall coating thin and thick wall paint, including styrene acrylic, pure acrylic, silicon a crylic-acid, water-based polyurethane emulsion and other exterior wall coating. This paint with water as solvent, non-toxic, non-flammable, easy application, coating performance is excellent, in line with the architectural coatings development direction of low pollution, environmental protection, is now as first choice for exterior wall coatings in China. By selecting different resin varieties, service life can reach 5 - 15 years. The main representative products are really stone paint, color stone paint, texture paint, etc. ( 2) Super weather resistance exterior architectural coatings originated in the United States, Japan and other countries a new type of fluorine resin coating. China has successfully developed and mass production, and applied in the high-rise building external wall. This kind of coating performance, is a leader in exterior wall coating. Its features are: (1) good weather resistance and durability, service life can amount to 15 20 years; (2) has a good stain resistance and chemical stability, metope paint after the rains washed out, like a new brush. (3) adhesion, directly without primer coating; (4) at room temperature, dry, good workability. Fluorine resin coating performance is good, but the price is expensive, it is mainly used for high-rise buildings with special requirements. ( 3) Functional architectural coatings with economic development and scientific progress, the application range of architectural coatings is put forward to the specific requirements of the more and more high. Although our country has developed some new varieties of functional architectural coatings, but is not enough, it is still one of the focus of future development. Existing fire prevention, insecticidal, mouldproof, insulation coatings should further consolidate and develop, make its products reach or close to international level. Heat insulation, prevent condensation, non-stick, adsorption, moisture absorption, insulation, anti-static, conductive coatings, etc. Should also actively develop and formulate relevant product standards accordingly. ( 4) To develop the Chinese architectural coatings new resin coating industry foundation is weak, product quality and variety can't meet the needs of the rapid development of national economy. Architectural coatings is no exception. Emulsioni paint, for example, a resin, have been used by day after day for more than a decade, the lack of new varieties can be timely replacement. To develop new varieties of paint, must carry out the research and development of new resin. Such as vinyl acetate - Tertiary ethylene carbonate ester copolymer emulsion, high viscosity thixotropic emulsion, organic - Inorganic latex interpenetrating network, soap-free emulsion, elastic emulsion, such as ambient crosslinking emulsion. Only with these new resin, architectural coatings can update, can meet the requirements of The Times.
