Abstract

The invention provides an automotive chassis protection board and a processing method thereof. The Automotive chassis protection board is produced from, by weight, 30-40 parts of polyvinyl chloride resin, 10-15 parts of polyimide resin, 10-20 parts of glass fiber, 20-30 parts of polypropylene, 15-20 parts of polyethylene glycol terephthalate, 25-30 parts of polymethylsiloxane resin, 15-25 parts of antioxidant, 30-35 parts of dibutyl phthalate, and 0.5-1 part of thermal insulation agent. The automotive chassis protection board has high weather resistance and aging resistance, heat dispersion is good, and machine-shaping rate is high.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to an automobile chassis guard plate and a processing method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, automobiles have become one of the common means of transportation for people's daily travel. The car chassis guard is one of the important parts of the car, which plays a role in protecting the bottom of the car. When the engine is running, due to the variety of road conditions, if it encounters poor road conditions, it will collide with the engine oil tank bottom case, causing the oil tank to leak oil, thereby causing a safety accident. At present, the common car chassis guards use more resin guards. However, the weather resistance and corrosion resistance of the resin guard plate are poor, and the molding rate of the product needs to be improved. Contents of the invention [0003] In view of this, th...
