Abstract

The present invention discloses a polypropylene composite material for a vehicle door decoration plate. The polypropylene composite material comprises the following raw materials by weight: 4-7 parts of hydroxyl-terminated polybutadiene, 2-3 parts of lithium silicate, 0.5-1 part of sodium mercaptobenzothiazole, 1-2 parts of diacetone alcohol, 0.7-1 part of calcium ascorbate, 2-4 parts of hexanedioic acid propanediol polyester, 0.1-0.3 part of 1-hydroxyethylidene-1,1-diphosphonic acid, 10-16 parts of graphite powder, 3-5 parts of polyamide wax micro-powder, 4-6 parts of tricresyl phosphate, 0.4-1 part of dimethylaminopropylamine, 4-6 parts of a modification auxiliary agent, 100-105 parts of polypropylene, and 0.7-1 part of an antioxidant 168. The polypropylene composite material of the present invention is mainly used for producing the vehicle door decoration plate, and has characteristics of excellent impact resistance, excellent toughness, excellent rigidity, excellent scratching resistance, excellent processing performance, and simple production process.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a polypropylene composite material used for automobile door trim. Background technique [0002] Polypropylene also includes copolymers of propylene and a small amount of ethylene. Usually translucent colorless solid, odorless and non-toxic. Due to the regular structure and high crystallization, the melting point can be as high as 167°C. Containing cobalt and zirconium, corrosion resistance, and the product can be sterilized by steam are its outstanding advantages. Low density, is the lightest general-purpose plastic. The disadvantage is that it has poor low temperature impact resistance and is easy to age, but it can be overcome by modification respectively; [0003] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, and it is one of the lightest varieties of all plastics. It is particularly stable to water, its water absorption rate...
