Abstract

The invention discloses a high-rigidity low-water-absorption nylon 6 composite material. The high-rigidity low-water-absorption nylon 6 composite material is characterized by being prepared from the following raw materials in parts by weight: 100 to 120 parts of nylon 6, 10 to 30 parts of barrier, 3 to 5 parts of nano montmorillonite, 30 to 50 parts of alkali-free glass fibers, 1 to 2 parts of silane coupling agent solution, 3 to 5 parts of nano layered silicate, 5 to 10 parts of acrylonitrile-butadiene-styrene-terpolymer, 1 to 10 parts of polytetrafluoroethylene, 3 to 5 parts of toughening agent, 1 to 5 parts of compatilizer, 0.1 to 1 part of heat resisting agent, 0.1 to 1 part of antioxidant, and 0.1 to 1 part of lubricating agent. The high-rigidity low-water-absorption nylon 6 compositematerial can still keep good rigidity in a water environment.

Description

technical field

[0001] The invention relates to the technical field of nylon modification, in particular to a nylon 6 composite material with high rigidity and low water absorption. Background technique

[0002] Polyamide fiber, commonly known as nylon, or PA for short, is a thermoplastic resin containing repeated amide groups on the main molecular chain. Moreover, the process temperature range is very wide, and its impact resistance and solubility resistance are better than nylon 66 plastics. It is widely used in petrochemical, national defense, machinery and textile industries. It is an important engineering plastic, but due to the large water absorption of nylon , leading to a large decrease in material rigidity, defects in mechanical strength, and high moisture absorption rate, resulting in a large molding shrinkage rate and affecting the dimensional stability of the product. Some nylon products that are used in contact with water, such as bathroom interior parts and irr...
