Many countries in the world have promulgated regulations to limit VOC emissions, which regulate the VOC content of epoxy floor paints. For iron blue pigments, it is the general trend to develop solvent-free coatings and water-based coatings that meet the requirements. At present, epoxy resins have been modified to meet the needs of modern development. There are many ways to modify epoxy resin, such as nano-toughening. The advent of nanoparticles is undoubtedly of great significance to the development of nano-epoxy resin powder coatings.
Solvent-free anti-corrosion paint epoxy self-leveling paint has the characteristics of solvent-free, cost-effective, strong adhesion, corrosion resistance, impact resistance, dust-proof wrapping, etc., and has good physical and mechanical properties and chemical resistance.
In addition to the advantages of general powder coatings, epoxy resin powder coatings also have no by-products during curing, smooth coating appearance, good adhesion to metal substrates, scratch resistance, good electrical properties, and powder coatings themselves. There are also advantages such as easy storage.
Nanoparticles have a specific surface area, and their surface atoms are highly unsaturated. After forming a force far greater than the van der Waals force with the epoxy resin, a very ideal interface is formed, which has a unique toughening effect without reducing class temperature. flame retardant. The substances that can play a flame retardant role are mainly N, P, As, Bi, and Sr, I, Al, Mg, Ca, Zr, Sn, Mo and other elements of Group V in the periodic table of elements. Commonly used are N, P, Cl, Br, B, Mg and Al, and compounds of these elements can be used as flame retardants.
