Antibacterial bamboo-plastic foamed composite door window material capable of removing formaldehyde and preparation method of antibacterial bamboo-plastic foamed composite door window material

Abstract

The invention discloses an antibacterial bamboo-plastic foamed composite door window material capable of removing formaldehyde and a preparation method of the antibacterial bamboo-plastic foamed composite door window material. The antibacterial bamboo-plastic foamed composite door window material is characterized by being prepared from the following raw materials in parts by weight: 1 to 3 parts of AgNO3, 60 to 70 parts of isotatic polypropylene, 1 to 2 parts of chitosan fibers, 10 to 15 parts of high melt strength polypropylene, 30 to 40 parts of bamboo powder, 10 to 15 parts of active carbon, 1 to 2 parts of corn fibers, 1 to 2 parts of emery powder, 20 to 25 parts of Cu(NO3)2, 1 to 3 parts of stearic acid, 1 to 3 parts of calcium stearate, 1 to 3 parts of foaming agents AC1601, 10 to 15 parts of zinc stearate, 50 to 60 parts of a NaOH solution and 1 to 3 parts of a ylate emulsion. According to the antibacterial bamboo-plastic foamed composite door window material capable of removing formaldehyde, polyacrylate and Cu(NO3)2 are used for modifying active carbon and diamond, so that the load of Cu(NO3)2 on the surface and in holes of the active carbon and the diamond is promoted; by the cooperative adding of silver nitrate, the silver nitrate is heated and decomposed into silver ions, so that the composite material is excellent in antibacterial property.

Description

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