Abstract

The invention relates to a composite and a preparation method thereof, in particular to a polyamide 6 composite and a preparation method thereof. Non-alkali chopped fibers are selected to serve as a reinforcing agent of the pyamide 6 composite, and compatilizer is added to improve fatigue durability and low-temperature brittleness of glass fiber reinforcing materials. Coupling reagents, lubricating agents and inorganic minerals are added to improve the combination of the polyamide 6 composite and the glass fibers, and dispersion of the glass fibers in the polyamide 6 composite is enhanced, so that the glass fibers are not prone to being exposed outside the surface, and a good surface is achieved. The polyamide 6 composite and the eparation method thereof have the advantages that the polyamide 6 composite can be used for injection molding of automobile doors and window frame decoration strips.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a composite material and a preparation method thereof, in particular to a polyamide 6 composite material and a preparation method thereof. Background technique [0002] In the automotive industry, the components involving polyamide 6 in its structure or decoration have become a highly concentrated area of ​​research and development. In addition, the market has higher and higher requirements for injection molding grade polyamide 6 materials, and the development of this field is becoming more and more rapid. .
