    The application of fireproof coatings in organic synthetic materials has broad prospects, with the large number of applications of organic synthetic materials, halogen-containing and other hard-to-burn organic polymers often lead to material deterioration, shortened service life and higher prices.
    characteristics and types of fire-resistant coatings:
    fire-resistant coatings are used on flammable substrate surfaces to change the combustion properties of material surfaces and prevent the rapid spread of fire; Or for use in building components, to improve the fire resistance limits of components of special coatings, called fire-resistant coatings. Fireproof coatings are called fireproof coatings, or flame retardant coatings, by brushing them on the surface of those flammable materials, improving the material's fire resistance, slowing the spread of flame, or preventing combustion for a certain period of time.
    many types of fire-resistant coatings, but according to the use of fire-resistant coatings and fire-resistant coating thickness, generally divided into finish-type coatings and steel structure fire-resistant coatings. Decorative fire-resistant coatings are generally used as protective materials for flammable substrates, with a certain degree of decorative and fire-resistant, but also divided into water and solvent-based two categories. The steel structure fire protection coating is mainly used as a protective material of non-combustion body components, this kind of fire protection coating is relatively thick, and the density is small, the thermal conductivity is low, so it has excellent insulation performance, but also divided into organic fire protection coating and inorganic fire protection coating.
    Development and Market Outlook of China's Fire Protection Coatings:
    From the history of China's paint industry development, raw materials and their additives have always been a constraint and weak link in the development of coatings industry. The raw materials and additives used in fireproof coatings are not only few varieties, but also unstable in quality and high in price, which seriously restricts their development. To meet the current state of China's environment in particular to meet the anti-fouling and corrosion-resistant composite technology of the base material is very few, there are many or blank.
    A considerable part of China's existing raw materials in the specifications and quality changes a lot, production often appears to use the same manufacturer's different batch number of raw materials, not only to the product quality caused great differences, but also to the manufacturer's production and technology development has brought a lot of difficulties. The small variety and poor function of additives seriously affect the coating performance and episodural performance of fire-resistant coatings, resulting in a long-term gap between domestic products and foreign products. Foreign raw materials, coating additives product varieties, full function, applicability, for paint manufacturers to provide a variety of additives, especially with composite functions of additives, has been generally welcomed. Pigments are the masters of giving fire-resistant paint colors and beautifying colorful buildings. At the same time, it is also one of the most headache problems in the development of fire-resistant coatings, especially in the use of fire-resistant coatings.
    Developed countries, the use of fire-resistant paint in building exteriors reached 80%, while the use of fire-resistant coatings in China's building exterior is much lower than in comparison, which is directly related to the poor quality of China's domestic pigments in weather resistance. For a long time, exterior paint, especially colored paint painted to the wall, less months, more than two or three years, or even a rain, so that the bright color face is completely different, serious color change. In recent years, foreign major pigment companies into the Chinese market, white pigment (titanium dioxide) is basically provided by the United Kingdom ICI, the United States DuPont company, all kinds of pigment domestic enterprises are also partially adopted, but the high price makes it difficult for enterprises to accept. Although some of their pigments have successful examples of use abroad, they may not be guaranteed in China due to differences in climate, environment, service life and construction quality. Because as a paint product, its color preservation is good or bad, first of all, must be pigments with high quality to meet the performance of a variety of outdoor applications, while color preservation and the content of the substiter, color saturation has a direct relationship. Global coating network believes that, in order to develop and improve China's fire-resistant coating products, to ensure product quality, we must accelerate the development of high-performance exterior paint composite technology to meet the base materials, supporting paint additives and high-quality pigments.
    under normal circumstances, fire-resistant paint as a high-level wood decorative materials of the outer layer, with good decorative effect; When under fire, it can expand and form a uniform and dense honeycomb-like or spongy carbon foam layer, so that the flame and object isolated, prevent or delay the combustion, in order to achieve the purpose of extinguishing fire, the combustible substrate has a good protective effect. Fire-resistant coatings are generally composed of non-combustible or hard-to-burn organic polymer resin as the main body, the organic polymer resin by special group modified, the resin itself can carry a certain amount of flame retardant group and foaming group, and then appropriately add a small amount of flame retardant, foaming agent, carbon source, etc. to form a fire prevention system. At the same time, the pigments used in fire protection coatings, commonly used in white, titanium, mica and asbestos, because these pigments have a high efficiency of heat dissipation, but also conducive to fire prevention, in which the white powder to infrared reflection capacity is strong, when the flame can reflect heat, widely used in fire protection coatings.
    the application of fire-resistant coatings in organic synthetic materials has broad prospects, with the large number of applications of organic synthetic materials, halogen-containing and other non-flammable organic polymers often lead to material deterioration, shorter service life, higher prices. It is not only possible to maintain the excellent performance of the original organic synthetic materials, but also to be economically applicable to fire protection by applying fire protection coatings to its surface. In addition, the structural strength is lost when ordinary steel is heated to about 540 degrees C. Concrete structures are also prone to cracking and disintegration under the action of high temperature flame. Therefore, the steel structure and concrete structure fire protection, so that they can be in the event of fire can extend the time of deformation damage, to fight the fire to win time, reduce fire losses, people pay great attention to. The application of fireproof coatings in steel and cement structures is expanding.
