Hydrophobic bamboo-plastic expanded composite door and window material capable of removing formaldehyde and preparation method thereof

Abstract

The invention discloses a hydrophobic bamboo-plastic expanded composite door and window material capable of removing formaldehyde and a preparation method thereof. The material is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of SiO2, 60-70 parts of isotactic polypropylene, 1-2 parts of ZnO, 10-15 parts of high-melt-strength polypropylene, 30-40 parts of bamboo powder, 10-15 parts of active carbon, 1-2 parts of emery powder, 1-2 parts of CaCO3, 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 a NaOH solution and 1-3 parts of polyacrylate emulsion. According to the hydrophobic bamboo-plastic expanded composite door and window material, polyacrylate and Cu(NO3)2 are used for modifying active carbon and diamond, thereby promoting the load of Cu(NO3)2 in the surfaces and ducts of active carbon and diamond; and hydrophobic inorganic nano particles are fixed on the surface of bamboo fiber by virtue of polymer emulsion, so that the durability of the super-hydrophobic structure on the surface of the bamboo fiber is effectively prolonged.

Description

technical field [0001] The invention relates to a bamboo-plastic composite material, in particular to a hydrophobic and 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 transportatio...
