Flame-retardant formaldehyde-removable bamboo-plastic foamed door-window material and preparation method thereof

Abstract

The invention discloses a flame-retardant formaldehyde-removable bamboo-plastic foamed door-window material and a preparation method thereof. The material is characterized by being prepared, by weight, 1-2 parts of vinyl phosphate, 60-70 parts of isotatic polypropylene, 0.5-1 part of vinyl methyl phosphate, 10-15 parts of high-melt-strength polypropylene, 30-40 parts of bamboo powder, 10-15 parts of activated carbon, 1-2 parts of corn meal, 1-2 parts of emery powder, 20-25 parts of Cu(NO3)2, 1-3 parts of stearic acid, 1-3 parts of calcium stearate, 1-3 parts of foamer AC1601, 10-15 parts of zinc stearate, 50-60 parts of NaOH solution and 1-3 parts of polyacrylate emulsion. Polyacrylate and Cu(NO3)2 are utilized to modify activated carbon and diamond, so that load of Cu(NO3)2 in the surfaces and holes of activated carbon and diamond; vinyl phosphate and vinyl methyl phosphate are added, so that flame-retardant performance of the material is improved.

Description

technical field [0001] The invention relates to a bamboo-plastic composite material, in particular to a flame-retardant, formaldehyde-removable bamboo-plastic foam composite door and window material 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 transportati...
