Abstract

The invention provides an environment-friendly type cracking-resistant impact-resistant composite material for architecture decoration and a preparation method therefor. The environment-friendly type cracking-resistant impact-resistant composite material for architecture decoration is characterized by comprising matrix, wherein preparation raw materials for the matrix comprise: 20wt%-74.8wt% of matrix resin, 5wt%-20wt% of modified resin, 5wt%-20wt% of reinforced fibers, 10wt%-64.8wt% of an inorganic filling material, 0wt%-5wt% of a brightening agent, 0.1wt%-1wt% of an antioxidant, 5wt%-20wt% of a flame retardant and 0.1wt%-1wt% of an anti-light aging agent, wherein the matrix resin is thermoplastic polyolefin resin, and the modified resin is a polar thermoplastic polymer. The environment-friendly type cracking-resistant impact-resistant composite material adopts the polar thermoplastic polymers including, but not limited to polycarbonate, polyformaldehyde, polyester, ABS and the like to carry out a matrix resin polar modification, thereby improving polarity of the matrix resin, improving adhesion stress between a coating material and the matrix resin, improving a product coating processing process, improving the quality of an architecture decoration product, and prolonging the service life of the product.

Description

technical field [0001] The invention uses high-performance fiber-reinforced thermoplastic macromolecules and modified additives as raw materials to prepare an environmentally friendly, low-energy consumption, and crack-resistant building decoration material through processes such as blending and extrusion, injection extrusion, and coating attachment. Background technique [0002] Architectural decoration materials include floor decoration, wall decoration, top surface decoration and indoor functional decoration materials, such as floor tiles, wall veneer tiles, ceiling decorative panels and ceramic sanitary products for daily use. In the prior art, the above decoration materials Made of ceramic materials, the preparation process adopts high energy consumption, high pollution and non-recyclable manufacturing processes such as green body sintering and glaze sintering; the product will be caused by uniformity of sintering temperature, differences in material expansion and contra...
