Problems solved by technology

[0003] 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;
[0004] 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;
[0005] 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 material for an automotive spoiler and a preparation method thereof. The material for an automotive spoiler comprises the following raw materials (by weight): 30-50% of ABS resin, 15-25% of AS resin, 25-40% of ceramic fiber, 0.05-1.5% of a compatilizer, 0.5-2% of a composite coupling agent, 0.3-0.8% of an anti-stress cracking agent, 0.5-1% of a heat stabilizer, 0.5-1% of a light stabilizer and 0.2-0.6% of a processing agent. By preparation of the composite coupling agent, pretreatment of ceramic fiber, mixing and extrusion molding, the automotive spoiler material with excellent tensile strength, bending strength, flexural modulus, impact strength, liquidity index, weatherability, scratch resistance, chemical resistance and stress cracking resistance is prepared. The material also has excellent thermal oxidative aging resistance, mechanical property and low warpage, and can meet application requirements of an automotive spoiler.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a material for an auto spoiler and a preparation method thereof. Background technique [0002] There are three types of car spoiler materials commonly used in the market: [0003] 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; [0004] 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; [0005] The third is carbon fiber. The spoiler made of carbon fiber has high strength and high durability. The disadvantage is that it is expensive. [0006] Therefore, it is necessary to design a low-cost, easy-to-process composite material for automobile spoilers to meet the needs of consumers. Contents of...
