In recent years, the development trend of color-coated coil industry in my country is good. With the demand for building materials, various types of color-coated coils are popular. I roughly visited the market and found that the following four coatings are more popular. Let's take a look!
Fire retardant coating is a coating that plays a physical protective role on the substrate and has flame retardant and fire resistant effects. The most important one is the foaming fire retardant coating, which can foam at a certain temperature to form a fireproof and heat-insulating layer. my country's fire retardant coating is mainly steel structure fire retardant coating. In steel structure construction, steel will soften and lose structural strength when heated to about 600℃, so this kind of coating is needed for protection. Ultra-thin (2-3mm) steel structure fire retardant coating was once a domestic blank and has been entrusted to import. Although some flame retardant additives such as ammonium polyphosphate and melamine phosphate are still inferior to foreign raw materials, the above progress has made my country's fire retardant coating technology and level not far from the international advanced level.
Floor coating is a type of coating that was born with the tide of reform and opening up. As foreign manufacturers continue to enter China, its use and influence are constantly expanding. In the past, the production sites of industrial and mining enterprises were exposed and there was no floor coating to protect them. Therefore, dust was everywhere during operation, which affected the appearance of the factory. The working sites of joint-stock and sole proprietorship enterprises are all covered with floor coatings, so the environment is clean and the operation is quiet. As a result, the floor coating industry has flourished. In the 1980s, there were only a few companies producing floor coatings, but now there are more than 500 companies. Its application scope has expanded to the home and commercial markets. The varieties it produces have also grown from simple solvent-based to water-based and solvent-free types. As a result, it has expanded from a single protection to a variety of wear-resistant, antistatic, anti-slip and self-leveling types.
my country's nanotechnology has been at the forefront of the world. In order for nanomaterials to play a role in coatings, there must be two conditions. One is that the stability of nanomaterials in coatings is good, and the other is that nanomaterials can maintain a good dispersion state in coatings. At present, China has achieved good results in the field of architectural coatings, that is, nanomaterials can improve the weather resistance of architectural exterior wall coatings and enhance the antibacterial effect of interior wall coatings, and industrialization preparations are being carried out; the application of nanomaterials in industrial coatings, such as improving the wear resistance of coatings, the conductivity of coatings, and functional coatings, has achieved initial results, thus bringing my country's research and development of nano-composite coatings to a new level.
Since the 1960s, my country has been engaged in the research and development of coatings in this area. In the past two decades, due to reform and opening up and the advancement of chemical synthesis technology, my country's research on camouflage coatings has taken a big step forward, and the gap with foreign advanced technologies has become smaller and smaller. At present, camouflage coatings for single anti-reconnaissance capabilities, such as optical camouflage coatings, near-infrared camouflage coatings, infrared camouflage coatings, camouflage cooling coatings, and anti-radar camouflage coatings, have achieved good results and have been put into use, and research and development in compatible spectral absorption for multiple reconnaissance capabilities and multi-effect compatible coatings have also achieved urgent progress.
