Abstract

The invention relates to a polyvinyl chloride low-foaming car plate and a preparation method thereof. The polyvinyl chloride low-foaming car plate is characterized by comprising the following raw materials in parts by weight: 50-80 parts of polyvinyl chloride resin, 12-20 parts of calcium carbonate, 2-5 parts of a stabilizer, 0.25-1 part of a foaming agent, 1-3 parts of light-weight master batch, 0.4-2 parts of polyethylene wax, 0.3-1 part of a lubricating agent, 1-5 parts of an acrylate processing modifier, 1-5 parts of chlorinated polyethylene, 0-0.3 part of a fluorescent whitening agent, 0-0.1 part of ultramarine, 1-3 parts of titanium dioxide and 5-15 parts of a foaming regulator, wherein the total weight parts of the raw materials are 100 parts. The polyvinyl chloride low-foaming car plate disclosed by the invention has light weight (the density being less than or equal to 605kg/m<3>), and meanwhile, is high in hardness, excellent in mechanical property, good in size stability, water-resistant, corrosion-resistant and mildew-resistant, can not be damaged by worms, is soundproof, heat-insulating, pollution-free and long in service life, has good flame-retardant properties, is a novel environment-friendly material for replacing wood materials and bamboo floors, can be used for reducing the weight of a car body when being applied to the floor of a car, is good in energy-saving effect, and meanwhile, can be used for prolonging the service life of the car floor and reducing the maintenance cost.

Description

technical field [0001] The invention belongs to a novel automobile plate, in particular to a polyvinyl chloride low-foaming automobile plate. Background technique [0002] In recent years, with the rapid development of the domestic automobile industry, auto parts, interior decoration, floor materials and other supporting products are also changing with each passing day. The traditional bamboo and wood floors used in automobiles are easily damaged, cracked, moldy, rotten, and moth-eaten. Phenomena, high density, short service life, large differences in hardness, toughness, and quality of wood and bamboo, and poor waterproof and fireproof performance, it is no longer suitable for the energy-saving and environmental protection policies advocated by the state. Polyvinyl chloride low-foaming board is a new type of environmentally friendly material developed in recent years that "replaces wood and steel with plastic". It was the first to introduce equipment and technology from Eur...
