Problems solved by technology

[0004] The structure of ordinary alkyd resin only contains C-C and C-O bonds, so the surface tension of ordinary alkyd resin is high and the antistatic performance is not good. Although alkyd resin is cheap, it cannot meet the requirements of some special coatings ; And the aging resistance and self-cleaning function are relatively poor, so it is especially important to develop a multi-functional, cost-effective water-based resin
[0005] At present, alkyd resins used on the surfaces of plastic, wood, metal, etc. need to add other additives for anti-fouling, waterproof, and anti-static. The additives are prone to shortcomings such as uneven dispersion and limited performance in the coating. Therefore, an anti-fouling , Modified alkyd resin with antistatic function is imperative
