Abstract

The invention discloses an automotive polyvinyl chloride interior trimming panel and a preparation method thereof, belongs to the technical field of polyvinyl chloride panels, and solves the problemsthat the thickness, the hardness, the bending strength and the like of existing wood-plastic panels cannot meet the requirements of automotive interior trimming panels. The polyvinyl chloride interiortrimming panel is prepared from 80-100 parts of polyvinyl chloride SG8-type resin, 40-50 parts of heavy calcium carbonate, 10-20 parts of a wood-plastic reclaimed material, a foaming regulator as well as ingredients including a calcium-zinc stabilizer, an interior lubricant, an exterior lubricant, a foaming agent, wood flour and the like. The preparation method of the panel comprises steps as follows: the polyvinyl chloride SG8-type resin and the ingredients are put into a hot-mixing pot for hot-mixing, then the foaming regulator and calcium powder are put sequentially for hot-mixing, the wood-plastic reclaimed material is put finally, the mixture is put into a cold-mixing pot for cooling after hot-mixing, is sent to a mold for extrusion finally after being plasticized by seven sections of double screws of a barrel, is subjected to cooling press-fitting shaping by a shaping platform and is pulled out by a pulling machine for cutting forming, and a finished product is obtained. The invention is applicable to the automotive interior trimming panel.

Description

technical field [0001] The invention relates to a polyvinyl chloride automotive interior trim panel and a preparation method thereof, belonging to the technical field of polyvinyl chloride plates. Background technique [0002] Wood-plastic panels can be made into various cross-sectional shapes and sizes by sanding. They have the advantages of being paint-free, maintenance-free, long-life and reusable. They are useful for making full use of renewable resources such as waste plastics and wood processing waste, and solving white pollution. It is of great significance to restrain the overexploitation of forest resources and protect the environment. Compared with unfoamed wood-plastic materials, the use of microcellular foaming technology to produce foamed wood-plastic materials can reduce the amount of resin, improve product strength and rigidity, and has low cost, low density, small wear and tear on equipment, no pollution and degradable And other characteristics, it can also ...
