Problems solved by technology

[0005] The first is FRP. The spoiler made of FRP is relatively close to the body line. The disadvantage is that its structural design freedom is low and its molding processability is average;
[0006] The second type is aluminum alloy. The spoiler made of aluminum alloy has a strong metallic appearance, good diversion effect, high density of defects, and low degree of freedom in structural design;
[0007] The third is carbon fiber. The spoiler made of carbon fiber has high strength and high durability. The disadvantage is that it is expensive.

Abstract

The invention discloses a polycarbonate alloy material applied to an automotive spoiler. The polycarbonate alloy material is prepared from the following components in percentage by weight as shown in the specification, wherein the polycarbonate alloy material is prepared from polycarbonate resin as matrix resin and thermoplastic polyester resin as auxiliary resin, so that the prepared spoiler has the advantages of large degree of freedom of structural design, good molding processing property, low density, low cost and the like. Hollow glass beads are taken as a filling base material, and a compatible flexibilizer, a coupling agent, an anti-stress cracking agent, an organic light stabilizer and the like are taken as processing agents, so that the prepared automotive spoiler has the advantages of excellent tensile strength, bending strength, flexural modulus, impact strength, liquidity index, weather fastness, scratch resistance, chemical corrosion resistance and stress cracking resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polycarbonate alloy material used for automobile spoilers and a preparation method thereof. Background technique [0002] The car spoiler, also known as the car tail, is an additional plate installed above the rear of the car. Its function is to reduce the lift of the rear of the car during driving and increase the grip of the rear wheels, thereby improving the stability of the car at high speed. [0003] Automobile spoiler belongs to the exterior parts of automobiles, and its material needs to have good cold and heat alternating, resistance to humidity and heat aging, impact resistance, chemical corrosion resistance, vibration resistance, weather resistance, scratch resistance, good dimensional stability, etc. . [0004] There are three types of car spoiler materials commonly used in the market: [0005] The first is FRP. The spoiler made of FRP is relatively close...
