Problems solved by technology

However, nylon has amide bonds, high water absorption, and nylon is a partially crystalline material with poor dimensional stability. Generally, nylon needs to be modified to increase the strength and modulus of nylon materials, but the commonly used modified nylon in the market Although the material has good mechanical properties, it still has the defects of poor flame retardancy and poor reusability

Abstract

The invention relates to the field of engineering machinery, in particular to a reusable nylon material for engineering machinery. The reusable nylon material comprises the following raw materials inparts by weight: 100 parts of caprolactam, 8 to 12 parts of 6-aminocaproic acid, 0.5 to 2 parts of 2,3,3,4'-biphenyl tetracarboxylic dianhydride and 0.05 to 0.5 part of nanometer mica powder. According to the invention, the defects of poor flame retardancy and poor reusability of nylon materials on the market at present are overcome. The nylon material is modified by adding the 2,3,3,4'-biphenyl tetracarboxylic dianhydride and the nanometer mica powder, and the obtained modified nylon material has good flame retardancy and reusability on the basis of maintaining good mechanical properties.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a reusable engineering machinery nylon material. Background technique [0002] Nylon is currently the material with the largest consumption of the five major engineering plastics. Nylon has the advantages of excellent mechanical properties, chemical resistance stability, and small friction coefficient. It is used in automobiles, textiles, electronics, electrical appliances and other fields, especially in construction machinery. application is more extensive. However, nylon has amide bonds, high water absorption, and nylon is a partially crystalline material with poor dimensional stability. Generally, nylon needs to be modified to increase the strength and modulus of nylon materials, but the commonly used modified nylon in the market Although the material has good mechanical properties, it still has the defects of poor flame retardancy and poor reusability.
