Abstract

The invention relates to the field of plastic-coated aluminum profiles, and particularly discloses a wood-like flame-retardant plastic-coated aluminum profile and a preparation method thereof. The wood-like flame-retardant plastic-coated aluminum profile is composed of an aluminum profile and a coating layer outside the aluminum profile, wherein the coating layer is composed of the following components in percentage by weight: 10-50% of adhesive resin, 10-35% of toughening resin, 5-20% of a filler, 15-35% of a flame retardant, 0.1-1% of an anti-dripping agent and 0.4-2.3% of other auxiliary agents, wherein the adhesive resin is at least one selected from a polyethylene copolymer and maleic anhydride-grafted polyolefin; and the toughening resin is at least one selected from ultra-high-molecular-weight polyethylene and polypropylene. The plastic-coated aluminum profile has the advantages that bonding force between the coating layer and the aluminum profile is improved, and therefore, thenail-holding force of the overall structural strength of the plastic-coated aluminum profile is improved.

Description

technical field [0001] The application relates to the field of plastic-clad aluminum materials, more specifically, it relates to a wood-like flame-retardant plastic-clad aluminum profile and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, more and more people choose furniture and decoration materials made of solid wood, which greatly intensifies the felling of trees and is not conducive to sustainable development. [0003] Later, wood-plastic profiles appeared, which are made of low-value biomass fibers such as sawdust, wood chips, bamboo chips, rice husks, wheat straw, soybean hulls, peanut shells, bagasse, and cotton straw as the main raw materials, and are formed into wooden cores. , the outer surface is covered with a plastic layer, which solves the problem of recycling waste resources in the plastic and wood industries. [0004] However, the quality of wood-plastic profiles is large and the structural streng...
