Vehicle polypropylene composite material containing cobalt and zirconium

Abstract

The present invention discloses a vehicle polypropylene composite material containing cobalt and zirconium. The vehicle polypropylene composite material comprises the following raw materials by weight: 0.1-0.2 part of cobalt orthosilicate, 1-2 parts of potassium zirconium carbonate, 0.8-1 part of alkenyl succinic anhydride, 0.6-1 part of polyoxyethylene oleate, 4-5 parts of silicon carbide, 3-5 parts of diisodecyl adipate, 2-4 parts of calcium stearate, 2-3 parts of polyisoprene, 1-2 parts of tetrabutyl ammonium bromide, 91-100 parts of polypropylene, 10-13 parts of light calcium carbonate, 0.6-1 part of hexamethylphosphoric triamide, and 3-4 parts of a modification auxiliary agent. According to the present invention, the vehicle polypropylene composite material is added with cobalt, zirconium and other heavy metals so as to substantially improve the surface resistance and enhance the impact resistance, wear resistance and other mechanical properties, can be used for vehicle parts, such as vehicle instrument panels, bumpers and other materials, and has characteristics of high safety and high stability.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a polypropylene composite material for vehicles containing cobalt and zirconium. 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 ...
