Automotive dashboard material capable of improving antistatic property through modified graphene

Abstract

The invention discloses an automotive dashboard material capable of improving the antistatic property through modified graphene. The automotive dashboard material is prepared from raw materials in parts by weight as follows: 100-105 parts of polypropylene powder, 20-22 parts of methyl methacrylate, 30-32 parts of polycarbonate powder, 10-11.5 parts of 200-mesh kaolin, 0.6-0.7 parts of polyvinyl alcohol, 3-3.5 parts of divinyl benzene, 0.2-0.22 parts of tween 80, an appropriate amount of distilled water, an appropriate quantity of sodium chloride aqueous solutions with the concentration being 10wt%, 1.5-2 parts of ethoxylated alkyl acid amide, 3-4 parts of white oil, 100-105 parts of N,N-dimethylformamide, 5-6 parts of graphite oxide, 5-6 parts of hydrazine hydrate, an appropriate amount of ammonia water and 10-12 parts of isophorone diisocyanate. The manufactured automotive dashboard has excellent toughness, strength and antistatic and dustproof functions and a good self-cleaning effect.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, in particular to an automobile dashboard material with improved antistatic properties by modified graphene. Background technique [0002] Due to its unique spatial location, the instrument panel has more and more operating functions distributed in it. In addition to reflecting the basic driving status of the vehicle, the control of air vents, audio, air conditioning, lighting, etc. also gives more driving safety and driving pleasure. Therefore, in a car, the dashboard is a very unique component that combines safety, functionality, comfort and decoration. Therefore, it needs to have a certain rigidity to support its attached parts to ensure normal operation at high speed and vibration; at the same time, it needs to have better energy absorption so that it can reduce the external force alignment and the co-pilot's fatigue when an accident occurs. shock. With the world's automobile...

Problems solved by technology

However, polypropylene has high notch sensitivity and low notched impact strength, especially at low temperatures, which cannot meet the requirements of instrument panel materials.

[0003] In the article "Research on Glass Fiber Reinforced Instrument Panel Structure and Collision Analysis Considering Fiber Direction", adding glass fiber to polypropylene has the advantages of light weight, good corrosion resistance, and low noise, but there are also certain shortcomings. poor compatibility with resin, and the mechanical properties inside the injection molded parts cannot be fully guaranteed; this requires further modification of polypropylene to obtain a light weight, good corrosion resistance and impact resistance Materials with good toughness and good toughness for composite automobile dashboards
