Abstract

The invention discloses a finish coat material and a preparation method thereof. The finish coat material is prepared from the following components in parts by weight: 20-40 parts of hot melting resin, 10-30 parts of a silicone acrylic emulsion, 5-10 parts of an inorganic thickener, 5-15 parts of anti-crack fibers, 2-8 parts of a foaming agent, 3-10 parts of a polycarboxylic acid high performance water reducer, 5-15 parts of silica powder, 2-8 parts of an ultraviolet absorbent, 2-10 parts of a flame retardant, 1-4 parts of a defoamer, 3-12 parts of hydroxypropyl methyl cellulose, 2-8 parts of lignocellulose and 5-15 parts of kaolin. The preparation method disclosed by the invention is simple, low in cost and good in environment-friendly performance, has the advantages of good high-temperature resistance and weather resistance, and can prevent a cracking phenomenon.

Description

technical field [0001] The invention relates to the technical field of preparation of facing layer materials, in particular to a facing layer material and a preparation method thereof. Background technique [0002] The decorative surface material is a kind of flexible architectural decorative surface material, which is made of modified inorganic filler as the main raw material, high molecular polymer as the auxiliary agent, formed, baked, and irradiated and cross-linked by a special temperature-controlled molding system.
