Description

technical field [0001] The invention relates to a paint for decorating and protecting the painted surface, in particular to a modified two-component epoxy resin paint. Background technique [0002] At present, there are two types of two-component epoxy resin coatings curable at room temperature: one is ordinary epoxy resin coatings, and the other is tar-modified epoxy resin coatings. The former can be colored, and the latter is black or gray. Tar-modified epoxy resin coatings have poorer color than ordinary coatings, but have excellent chemical resistance and low price, and are suitable for occasions that do not require color. The disadvantages of room temperature curing epoxy resin coatings are: easy to yellow, easy to powder, and the initial flexibility is easy to gradually lose with time, and the curing conditions are harsh: avoid strong water, long curing time and poor low temperature curing. Contents of the invention [0003] The purpose of the present invention is t...
