Epoxy resin is a high-molecular polymer with a molecular formula of (C11H12O3)n, which refers to the general term for a class of polymers containing more than two epoxy groups in the molecule. It is the polycondensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, a variety of compounds containing active hydrogen can be used to open the ring, cure and cross-link to form a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin not only has a large output and a complete variety, but also new modified varieties are still increasing, and the quality is constantly improving.
Polyester resin coating is a coating with polyester resin as the main film-forming substance. It is formed by polycondensation of polyols and polyacids. The difference from polyurethane coatings is that the molecules of polyester coatings do not contain amino groups "-NH-". Polyester resin coatings are widely used in medium and high-grade coatings, low-pollution high-solids, and powder coatings.
Add quantitative diethanolamine and catalyst into the reactor, gradually add dimethyl adipate dropwise under certain reaction conditions, and continuously distill methanol during the reaction. Add solvent after the reaction, recrystallize, filter and dry to get HAA
