Abstract

The invention discloses a plastic nano coating, which is mainly made of the following raw materials in parts by weight: 10 parts of water-based acrylic resin, 2-12 parts of polylactate, 0.5-0.9 parts of pigment, and 5-15 parts of nano-titanium dioxide 10-20 parts of nano silicon dioxide, 6-12 parts of pentaerythritol, 8-14 parts of talc, 15-25 parts of mica. The invention also discloses a preparation method of the plastic nano paint. Compared with the prior art, the plastic nano-coating obtained in the present invention has low cost, simple process, strong adhesion and excellent adhesion performance, and has a relatively high fire resistance time, and the inside of the carbonized layer formed during combustion is thick, firm and dense, The flame retardant effect is obviously improved.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a plastic nano coating with excellent comprehensive performance and a preparation method thereof. Background technique [0002] Flame retardant coatings are currently a hot research topic in the coatings industry. Existing flame-retardant coatings are mainly flame-retardant coatings suitable for the surface of metal materials, wood surfaces or building materials. Compared with metal materials, wood materials or building materials, plastic materials have certain limitations in the selection of coatings, mainly Since plastic materials have high requirements for coating adhesion, they also have certain requirements for flame retardancy. [0003] At present, traditional plastic coatings have some defects, such as insufficient coating adhesion, easy layering, peeling off, short service life, and poor flame retardancy. Contents of the invention [0004] Purpose of the i...
