Abstract

The invention discloses a sound-absorbing noise-reducing formaldehyde-removing bamboo-plastic foamed composite door / window material and a preparation method thereof. The material is characterized by being made from the following materials according to parts by weight: 1-2 parts of asbestos fiber, 60-70 parts of isotactic polypropylene, 1-2 parts of sepiolite fiber 10-15 parts of high-melt-strength polypropylene, 30-40 parts of bamboo powder, 10-15 parts of activated carbon, 1-2 parts of carbon fiber, 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 foaming agent AC1601, 10-15 parts of zinc stearate, 50-60 parts of NaOH solution, and 1-3 parts of polypropylene; the activated carbon and diamond are modified with polyacrylate and Cu(NO3)2, promoting the loading of Cu(NO3)2 on the surface of and in ducts of the activated carbon and diamond; by cooperation with the added asbestos fiber, sound-absorbing effect of the composite material is enhanced.

Description

[0001] technical field [0002] The invention relates to a bamboo-plastic composite material, in particular to a sound-absorbing, noise-reducing and formaldehyde-removing bamboo-plastic foam composite door and window material 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 automobil...
