Problems solved by technology

[0002] Polyurethane paint is a kind of coating with excellent performance, which is widely used in furniture decoration, painting, architectural decoration, equipment anticorrosion, etc. The paint is usually made of polyester or alkyd resin and toluene diisocyanate or The trimer is formulated with additives. Due to the specificity of construction conditions and environmental requirements, the prepared floor paint is often prone to cracking, low gloss, poor adhesion, easy yellowing of the paint film, low hardness, Not wear-resistant, poor gloss and color retention, resulting in the above reasons, the performance of alkyd resin plays a key role, so the preparation of high-performance alkyd resin is the key technology to solve many defects of floor paint

Abstract

The alkyd resin with high solid content and low viscosity and used for floor paint is prepared with lauric acid, benzoic acid, adipic acid, trimethylol propane, neopentadiol, phthalic anhydride and other material. The alkyd resin is compounded with tolylene diisocyanate affixture or tripolymer. The coating has high adhesion, high hardness, high wear resistance, high shock resistance, good weather resistance, less volatile and other advantages, and the paint may be sprayed or brushed.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and is a modified alkyd resin with modified ultra-short oil degree hydroxyl terminated. Background technique [0002] Polyurethane paint is a kind of paint with excellent performance, which is widely used in furniture decoration, painting, building decoration, equipment anti-corrosion, etc. The paint is usually made of polyester or alkyd resin and toluene diisocyanate adduct or Trimer, mixed with additives, due to the specific construction conditions and environmental requirements, the prepared floor paint is often easy to crack, low gloss, poor adhesion, paint film easy to yellow, low hardness, No wear resistance, poor gloss and color retention, causing the above reasons, the performance of alkyd resin plays a key role, so the preparation of high-performance alkyd resin is the technical key to solve many defects of floor paint. Summary of the invention [0003] The purpose of the present invention ...
