Abstract

The invention relates to a composite reinforced nylon composition. The composite reinforced nylon composition consists of the following components in percentage by weight (wt%): 58.6 to 63.6 percent of nylon, 4 to 12 percent of carbon fiber, 15 to 20 percent of glass fiber, 3 to 5 percent of nano montmorillonite, 3 to 8 percent of toughening modifier and 0.4 to 6.4 percent of other auxiliaries. The other auxiliaries are a lubricating dispersing agent and an antioxidant. The invention also provides a preparation method of the composite reinforced nylon composition. Compared with the prior art, the composite reinforced nylon composition prepared by the preparation method disclosed by the invention has flat surface and high mechanical strength, has heat resistance, is conductive and has wide application range.

Description

technical field [0001] The invention relates to a nylon composition, in particular to a composite reinforced nylon composition and a preparation method thereof. Background technique [0002] Polyamide has good mechanical strength and rigidity, good wear resistance and other advantages, and is widely used in automotive parts, mechanical parts, electronic and electrical fields, etc., becoming the first of the five engineering plastics, replacing traditional metal materials in many applications . Simple glass fiber reinforced modification greatly improves the strength, creep resistance, wear resistance, etc. of the material compared with pure materials, but it still cannot meet some occasions that have higher requirements for high temperature resistance, heat resistance, and high strength. application. Carbon fiber has the characteristics of light weight, high tensile strength, wear resistance, corrosion resistance, creep resistance, electrical conductivity, heat transfer, et...
