Abstract

The invention discloses an impact-resistant and wear-resistant polyester industrial coating and a preparation method thereof. The impact-resistant and wear-resistant polyester industrial coating comprises the following raw materials by weight: 50-60 parts by weight of hydroxyl polyester resin, 10-60 parts by weight of silicone resin 20 parts by weight, 0.03-0.05 parts by weight of diisocyanate, 20-30 parts by weight of carboxyl-terminated butadiene rubber; the hydroxyl value of the hydroxyl polyester resin is below 5 mgKOH / g. The hydroxyl polyester resin is cross-linked by diisocyanate, silicone resin and carboxyl-terminated butadiene rubber. The introduction of silicone resin enhances the strength and hardness of polyester resin, and the introduction of butadiene rubber gives the copolymer resin flexibility. chain segment, so that the prepared coating film has strong impact resistance and wear resistance under stress.

Description

technical field [0001] The invention belongs to the field of industrial coatings, in particular to an impact-resistant and wear-resistant polyester industrial coating and a preparation method thereof. Background technique [0002] Thermoplastic polyesters are linear polymers prepared by polycondensation of saturated dibasic acids and diols. According to the dibasic acid monomer and diol monomer, it can be divided into a variety of thermoplastic polyesters. At present, the varieties that have been industrially produced and applied mainly include: polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polycyclohexylenedimethylene terephthalate (PCT) , polyethylene naphthalate (PEN), polybutylene naphthalate (PBN) and polytrimethylene terephthalate (PTT), etc., polyester is mainly used to produce polyester fiber (polyester), At the same time, as non-fiber films, plastics, packaging containers, adhesives, coating products, etc., it is widely used in light industry...
