High-strength and high-toughness PVC (Poly Vinyl Chloride) material for automotive interiors and preparation method of PVC material

Abstract

The invention discloses a high-strength and high-toughness PVC (Poly Vinyl Chloride) material for automotive interiors and a preparation method of the PVC material. The PVC material is prepared from the following raw materials in parts by weight: 36 to 48 parts of PVC resin SG-5, 18 to 26 parts of syndiotatic polypropylene, 10 to 15 parts of MABS (Methyl Methacrylate-Acrylonitrile-Butadiene-Styrene) resin, 12 to 18 parts of dicyclohexyl phthalate, 1 to 2 parts of naphthenic acid cerium, 0.5 to 1.5 parts of lanthanum oxide, 2 to 3 parts of calcium-zinc complex stabilizer, 3 to 5 parts of pentaerythritol tetrabenzoate, 4 to 6 parts of glycerol ester of rosin, 2.5 to 4.5 parts of salicylamide, 3 to 4 parts of isocetyl palmitate, 4 to 6 parts of bisphenol A disalicyate, 5 to 8 parts of polyester silicone oil, 10 to 15 parts of basic magnesium chloride whisker, 5 to 10 parts of graphene, 6 to 12 parts of zircon flour, 12 to 18 parts of nanometer composite powder, 1 to 2 parts of antioxidant 626 and 0.5 to 1.5 parts of antioxidant 1076. The prepared PVC material is excellent in comprehensive mechanical performance, i.e., the impact strength and toughness of the PVC material are greatly enhanced while the high tensile strength of the PVC material is maintained; meanwhile, the PVC material is excellent in fatigue resistance, creep resistance, chemical corrosion resistance, abrasion resistance and heat resistance. Thus, the performance requirements of the PVC material for the automotive interiors are completely satisfied.

Description

technical field [0001] The invention relates to a PVC material and a preparation method thereof, in particular to a high-strength and high-toughness PVC material for automobile interior decoration and a preparation method thereof. Background technique [0002] Polyvinyl chloride is a material with a wide range of uses. It is widely used in the automotive industry because of its excellent properties such as good rigidity, high strength, flame retardancy, corrosion resistance, and good electrical insulation, and it is rich in sources and low in cost. With the rapid development of the automobile industry, the performance requirements for PVC materials are getting higher and higher. Currently, the PVC materials used for automotive interiors on the market have the defects of low impact strength and poor toughness, and cracks appear under the action of external force. Therefore, , there is an urgent need to develop a high-strength and high-toughness PVC material for automotive int...
