Bamboo-plastic foaming composite door-window material containing magnesium hydroxide and preparation method of bamboo-plastic foaming composite door-window material

Abstract

The invention discloses a bamboo-plastic foaming composite door-window material containing magnesium hydroxide and a preparation method of the bamboo-plastic foaming composite door-window material. The bamboo-plastic foaming composite door-window material is characterized by being prepared by, by weight, 1-2 parts of magnesium hydroxide, 60-70 parts of isotactic polypropylene, 1-2 parts of magnesium oxide, 10-15 parts of high-melt-strength polypropylene, 30-40 parts of bamboo powder, 10-15 parts of activated carbon, 1-2 parts of corundum powder, 0.5-1 part of calcium sulfate, 20-25 parts of Cu(NO3)2, 1-3 parts of stearic acid, 1-3 parts of calcium stearate, 1-3 parts of foaming agent AC1601, 10-15 parts of zinc stearate, 50-60 parts of NaOH solution and 1-3 parts of polyacrylate emulsion. The bamboo-plastic foaming composite door-window material has the advantages that polyacrylate and the Cu(NO3)2 are used to modify the activated carbon and diamond, and loading of the Cu(NO3)2 on the surface of and in the ducts of the activated carbon and the diamond, is promoted; the magnesium hydroxide and the magnesium oxide are added to allow the material to have a flame retarding function.

Description

technical field [0001] The invention relates to a bamboo-plastic composite material, in particular to a bamboo-plastic foam composite door and window material containing magnesium hydroxide and a preparation method thereof. Background technique [0002] 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 industry and transportation indust...
