High-toughness formaldehyde removing bamboo-plastic foamed composite door and window material and preparation method thereof

Abstract

The invention discloses a high-toughness formaldehyde removing bamboo-plastic foamed composite door and window material and a preparation method thereof. The material is characterized by being prepared from, by weight, 2-5 parts of high-elasticity polypropylene fibers, 60-70 parts of isotactic polypropylene, 1-2 parts of SiO2, 10-15 parts of high-melt-strength polypropylene, 30-40 parts of bamboo powder, 10-15 parts of activated carbon, 1-2 parts of polyethylene, 1-2 parts of corundum powder, 20-25 parts of Cu(NO3)2, 1-3 parts of stearic acid, 1-3 parts of calcium stearate, 1-3 parts of a foaming agent AC1601, 10-15 parts of zinc stearate, 50-60 parts of NaOH solution and 1-3 parts of polyacrylate emulsion. The activated carbon and diamond are modified by polyacrylate and the Cu(NO3)2, and loading of the Cu(NO3)2 in pore passages and surfaces of the activated carbon and the diamond is promoted; due to addition of the high-elasticity polypropylene fibers and the like, elasticity of the material is improved.

Description

[0001] technical field [0002] The invention relates to a bamboo-plastic composite material, in particular to a bamboo-plastic foam composite door and window material with good toughness and capable of removing formaldehyde and a preparation method thereof. Background technique [0003] Bamboo-plastic foam composites have attracted much attention recently because they can overcome the defects of high density and brittleness of bamboo-plastic composites. Bamboo-plastic composite materials mainly include polyvinyl chloride and polyolefin plastics. Polyvinyl chloride-based composite materials will pollute the environment during manufacture, use and disposal. Polyvinyl chloride-based composite materials have low rigidity and maximum service temperature, and are not easy to degrade. Therefore, polypropylene (PP) wood-plastic foam composites have become a recent research hotspot. Bamboo-plastic foam composite materials have a wide range of applications, involving the automobile...
