Abstract

The invention relates to the technical field of paint, in particular to a two-component elastic paint. The two-component elastic paint used for a mobile phone shell is composed of main paint, a curing agent and diluent, and the main paint is prepared from, by mass, 35%-45% of polycarbonate resin, 3%-7% of matt powder, 0.7%-1.3% of hand feeling auxiliary, 40%-60% of solvent and 0.6%-2.2% of other auxiliaries; the mass ratio of the main paint to the curing agent to the diluent is 100:(15-20):(25-40). According to the two-component elastic paint used for the mobile phone shell, by adjusting composition of a formula, the problem that the elastic paint is prone to 'after-tack' is solved without affecting other properties, and the elastic paint is applicable to high-end products of the mobile phone shell and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a two-component elastic paint. Background technique [0002] There are generally four types of coatings for mobile phone casings: UV paint, ordinary PU paint, elastic paint, and PVD (vacuum plating). Among them, elastic paint is increasingly favored by consumers because it gives people a warm and velvety touch. According to relevant data, in the past two years of 2010 and 2011, elastic paint accounted for more than half of the various mobile phone casing coatings. However, most of the elastic paints on the market have insufficient durability. I believe that most consumers have experienced that mobile phones using elastic paints have been used for half a year or longer. Degradation, the paint film starts to become sticky gradually, and there are obvious traces when you scratch it with your nails, commonly known as "stick back". Contents of the invention [0003] In view of th...
