Abstract

The invention provides a novel polyamide nanocomposite. The components of the novel polyamide nanocomposite in parts by weight are as follows: 67 to 80 parts of nylon 6, 1 to 10 parts of nanosilicon dioxide, 0.1 to 0.3 part of coupling agent, 0.2 to 1 part of dispersant, 0.3 to 4 parts of lubricant, 0.1 to 1 part of antioxidant, 0.3 to 6 parts of stabilizer and 5 to 12 parts of flexibilizer. The invention also discloses a preparation method of the novel polyamide nanocomposite. The novel polyamide nanocomposite provided by the invention has high strength and good impact resistance.

Description

Technical field: [0001] The invention relates to a polyamide material, in particular to a novel polyamide nanocomposite material and a preparation method thereof. Background technique: [0002] Polyamide (PA, commonly known as nylon) is the first resin developed by DuPont in the United States for fiber, and it was industrialized in 1939. In the 1950s, the development and production of injection molding products began to replace metals to meet the requirements of lightweight and cost-reducing downstream industrial products. Polyamide has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, low friction coefficient, certain flame retardancy, easy processing, and is the most widely used project. One of the plastics, widely used in machinery, automobiles, electrical appliances, textile equipment, chemical equipment, aviation, metallurgy and other fields. However, the strength and ...
