Abstract

The invention discloses a scratch-resistant epoxy resin paint, which is prepared from 550-650 parts of polycarbodiimide resin, 2-6 parts of zinc bromide, 650-690 parts of bisphenol A diglycidyl ether resin, 2-8 parts of tetrabutylammonium iodide, and 300-500 parts of acetone. Therefore, the scratch-resistant epoxy resin paint is good in scratch resistance and solvent resistance, large in hardness and bright and transparent.

Description

technical field [0001] The invention relates to coatings, in particular to a scratch-resistant epoxy resin coating. Background technique [0002] Epoxy resin coatings are mainly used for coating the outer walls of tinplate and cans, but traditional epoxy resin coatings have poor scratch resistance and low hardness.
