Ultraviolet radiation aging resistant PVC material for automobile exterior and preparation method thereof

Abstract

The invention discloses an ultraviolet radiation aging resistant PVC material for an automobile exterior and a preparation method thereof. The ultraviolet radiation aging resistant PVC material is prepared from the following raw materials in parts by weight: 60-80 parts of SG-2 type PVC resin, 35-45 parts of bisphenol A type polysulfone, 20-30 parts of epoxy rubber seed oil, 16-22 parts of botryolite powder, 15-20 parts of iron-ore slag, 4-8 parts of glyceride monobehenate, 3-6 parts of cctadecyl stearate, 2-5 parts of low molecular weight polypropylene, 1-2 parts of magnesium myristate, 2-3 parts of zinc myristate, 1.5-2.5 parts of methyl 3,5-di-tert-butyl-4-hydroxybenzoate, 4-6 parts of dipropylene glycol monosalicylate, 15-25 parts of BOVC resin, 2-3 parts of butyl mercaptooxo stannane, 10-15 parts of titanium dioxide, 2-3 parts of inositol hexaphosphate, 10-15 parts of dipropylene glycol dibenzoate, 1-2 parts of 2-hydroxyl-4-methoxy diphenyl ketone and 19-27 parts of compound nano powder. The ultraviolet radiation aging resistant PVC material for the automobile exterior has excellent ultraviolet radiation aging resistant property, good chemical stability, lasting sunlight resistance, no cracking, long service life and good safety, also has good heat resistance, corrosion resistance and weather resistance and can completely meet performance requirements of a PVC material for the automobile exterior.

Description

technical field [0001] The invention relates to a PVC material and a preparation method thereof, in particular to an anti-ultraviolet aging PVC material for automobile exterior 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 of PVC materials are getting higher and higher. The PVC materials currently on the market for automotive exterior decoration have poor UV resistance and are prone to aging and cracking under long-term exposure to sunlight. Therefore, it is urgent to develop a new product. An anti-ultraviolet aging PVC material for automotive exterior decoration to meet mark...
