Abstract

The invention discloses a polypropylene-based wood-plastic composite material for indoor decoration and a preparation method thereof. The polypropylene-based wood-plastic composite material is prepared from the following components in parts by weight: 100 parts of polypropylene resin, 60 to 70 parts of parslane herb, 25 to 35 parts of wood powder, 15 to 23 parts of nano-montmorillonite, 5 to 7 parts of rare earth coupling agent, 5 to 7 parts of zinc stearate, 2 to 5 parts of plasticizer, 1 to 2 parts of antioxidant, 5 to 8 parts of filler, and 1 to 2 pars of foaming agent. The polypropylene-based wood-plastic composite material has the advantages that the anti-corrosion property and antibacterial property are good; the service life is longer; the polypropylene-based wood-plastic composite material is suitable for being used as indoor decoration materials.

Description

technical field [0001] The invention relates to the field of wood-plastic composite materials, in particular to a polypropylene-based wood-plastic composite material for interior decoration and a preparation method thereof Background technique [0002] Wood-plastic composites are modified thermoplastic materials filled and reinforced with wood fibers or plant fibers, which are extruded or pressed into profiles, panels or other products, which can replace wood and plastic products. The structure of wood-plastic composites can be seen as thermoplastics acting as the continuous phase, non-plastic wood as the dispersed phase, and the two phases are organically combined by chemical means, so that wood-plastic composites have the dual characteristics of plastic and wood. At present, the most widely used thermoplastics in wood-plastic materials are polypropylene, polyvinyl chloride, polystyrene, polyethylene terephthalate and polyethylene. Among them, polypropylene (PP) has high i...
