Abstract

The invention relates to a polycarbon-modified anti-after-tack elastic-feeling paint coating applied to spray coating as well as a preparation method and application thereof. The coating is prepared from the following components in parts by weight: 20-30 parts of polycarbon-modified resin, 10-18 parts of saturated polyester resin, 20-35 parts of butyl acetate, 10-30 parts of diacetone alcohol, 6-8 parts of extinction powder, 0.5-1 part of flatting agents and 0.05-0.15 part of driers. The coating can be applied to spray coating of plastic shells of electronic and electrical appliance products and has the advantages of excellent touch elastic hand feeling and after-tack resistance.

Description

technical field [0001] The invention relates to an organic coating, in particular to a polycarbon modified anti-viscosity elastic touch paint coating for spraying plastic shells of electronic and electrical appliances, a preparation method and application thereof. Background technique [0002] Therefore, at present, various electronic or electrical products, such as digital cameras, notebook computers, mobile phones, etc., have been widely used in people's lives. The shells of such products are mostly made of plastic and plastic materials. After the shells are processed and formed, they need to be sprayed with protective and decorative paint on the surface. With the improvement of people's cultural living standards and appreciation levels, it is generally required to resist Products with increasingly high-grade stickiness and tactility. [0003] In the prior art, the paint used for the casing is generally a polyurethane paint without any elastic feel. End users pay more an...
