Nylon 66 material and preparation method thereof

Abstract

The invention falls into the technical field of polymer material, and discloses Nylon 66 material and a preparation method thereof. The material comprises (by weight parts) Nylon 66 raw material 500-700, continuous carbon fibers 300-500, an antioxidant 6-10, a lubricant 4-8 and an anti-hydrolysis agent 5-15. Compared with prior art, the invention has reasonable design, simple operation and strong practicability; the adoption of continuous carbon fibers for reinforcing the Nylon 66 material results in that the length of carbon fibers in products can be kept at 3-6 mm, and as a result, the rigidity and the strength of the material are improved greatly, the impact resistance and the heat resistance of the material are improved remarkably, and the material possesses a long-term hydrolytic stability and a resistance to chemical corrosion.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and relates to a nylon 66 material and a preparation method thereof. Background technique

[0002] Polyamide resin is a chemical raw material with excellent performance and wide application. Due to its non-toxic, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, it can replace copper and other metals in machinery, chemicals, instruments, It is used in the manufacture of bearings, gears, pump blades and other parts in industries such as automobiles, but in some parts with relatively high strength requirements, especially in the military and aerospace fields, nylon 66 raw materials are difficult to meet the use requirements, and the use process In order to solve this problem, domestic and foreign enterprises have reinforced and modified nylon 66 with carbon fiber and glass fiber. Among them, carbon fiber reinforced nylon 66 material has excellent ...
