Problems solved by technology

[0002] In alkyd resin, because the ester bond on its molecular chain is easily hydrolyzed under weak alkaline conditions, the storage stability of alkyd resin is reduced, and the coating film has the disadvantage of easy yellowing, so the application of alkyd resin is limited. Restrictions; and alkyd resin dries slowly, takes a long time to cure, and has poor weather resistance
In order to improve the performance of alkyd resin, acrylic monomers can be used to modify alkyd resin through polyaddition reaction. The modified resin has excellent gloss and color retention and good storage stability, but the currently synthesized modified Alkyd resin adhesion, hardness and corrosion resistance can not meet the demand
