Corrosion-resistant glass fiber reinforced polypropylene material and preparation method thereof

Abstract

The invention relates to a corrosion-resistant glass fiber reinforced polypropylene material and a preparation method thereof, and belongs to the technical field of high polymer materials. In the components of the glass fiber reinforced polypropylene material disclosed by the invention, the polypropylene resin with high tensile strength and the superfine glass fiber are compounded, so that the impact strength and the tensile strength of a product can be effectively and synergistically improved, and the glass fiber reinforced polypropylene material meets the basic mechanical property requirements and the heat resistance requirements of existing automobile water chamber parts; the special nucleating agent and the inorganic filler are matched to achieve synergistic interaction, organic solvents such as ethylene glycol are effectively prevented from entering an interface of polypropylene resin and glass fiber, the interface stability of the whole material is protected, and finally the corrosion resistance of the product reaches the application standard; in addition, the crystallinity of the polypropylene resin can be effectively regulated and controlled, and the mechanical property of the obtained product is further improved. The invention also provides a preparation method and application of the corrosion-resistant glass fiber reinforced polypropylene material.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a corrosion-resistant glass fiber reinforced polypropylene material and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the main direction of automobile research is to reduce weight, save energy, reduce emissions, and improve safety performance. A major development trend, the demand of the automotive market has shifted to lighter weight sports vehicles, utility vehicles and other light vehicles, which also promotes the development of functional plastics to better performance. The car water chamber is used as the heat dissipation device of the car, and the coolant glycol has to undergo alternating high and low temperature changes. Therefore, the water chamber material is required to be resistant to chemical corrosion and high temperature resistance, as well as the mechanical properties of the material. ...
