Problems solved by technology

However, polyamide also has many disadvantages, such as high water absorption, easy embrittlement at low temperature and dry state, poor impact resistance, poor dimensional stability and insufficient heat resistance, etc. These problems make the use of polyamide restricted. Therefore, it is necessary to modify polyamides to overcome these shortcomings

Abstract

The invention discloses a polyamide composite material. The polyamide composite material comprises the following components in parts by weight: 100 parts of aliphatic polyamide, 21-37 parts of polyolefin elastomer, and 34-42 parts of diatomaceous earth , 5-17 parts of silicone rubber, 7-9 parts of filler, 16-23 parts of nanomaterials, 3-5 parts of polyethylene glycol, 2-5 parts of coupling agent, 1-2 parts of compatibilizer; the polyamide composite The material has good wear resistance, excellent impact resistance and good thermal stability, and is very suitable for use as auto parts.

Description

technical field [0001] The invention relates to a polyamide composite material. Background technique [0002] Polyamide (PA) is obtained by polycondensation of dibasic acid and diamine or amino acid, and is a general term for resins containing repeated amide groups in the molecular chain. Polyamides can be divided into three groups according to their structure: aliphatic polyamides, aliphatic-aromatic polyamides and aromatic polyamides. Among them, there are many varieties of aliphatic polyamides, large output and wide application. The name of this type of polyamide is mainly determined by the specific number of carbon atoms in the synthetic monomer. Polyamide synthesis methods can be divided into three main types: melt polycondensation, interfacial polycondensation, and solid-state polymerization. [0003] Polyamide has good mechanical properties, heat resistance, wear resistance, chemical resistance, flame retardancy and self-lubrication, and is easy to process and has a...
