Abstract

The invention provides a nylon composite material with star branched structure, applicable to automobile induction manifold. The nylon composite material is composed of the following components by mass percentage: 40-68% of nylon, 0-10% of POE elastic body, 0-35% of short glass fiber, 0.05-5% of star branching agent and 1.5-12% of assistant; wherein the short glass fiber is alkali-free short glass fiber treated by silane coupling agent; the molecular formula of the star branching agent is, R is aromatic chain segment, aliphatic chain segment or epoxy chain segment, R' is amino, carboxyl or hydroxyl functional group capable of reacting with nylon end group, and R' functional group quantity is more than or equal to 3. The composite material of the invention has the advantages of super bursting strength, excellent processing liquidity and high surface finishment and completely meets the production and application requirement of automobile nylon induction manifold, the raw material thereof is available, production processing is simple, and the invention is applicable to popularization and application.

Description

technical field [0001] The invention relates to a special nylon material for an automobile intake manifold, in particular to a nylon composite material with a star-shaped branched structure and a preparation method thereof. The material is suitable for an automobile engine intake manifold. Background technique [0002] In recent years, with the improvement of people's requirements for automobile lightweight and energy saving, it has become one of the themes of the automobile industry to replace metal materials with lightweight engineering plastics for automobile structures and parts. [0003] The application of nylon intake manifold is one of the most typical examples in recent years that the automotive industry has applied engineering plastics instead of metal materials to achieve the above goals. The intake manifold of the automobile engine is one of the main components of the automobile power system. It is located in the center of the engine room. The gas enters the cylin...
