A kind of anti-hydrolysis continuous carbon fiber reinforced nylon 6 material and preparation method thereof

Abstract

The invention belongs to the technical field of a high polymer material and discloses a hydrolysis resistant continuous carbon fiber reinforced nylon 6 material and a preparation method thereof. The material disclosed by the invention comprises the following components in percentage by weight: 500-700 parts of nylon 6, 300-500 parts of continuous carbon fiber, 6-10 parts of oxidation inhibitor, 4-8 parts of lubricating agent and 5-15 parts of hydrolysis resistant agent. The invention also discloses the preparation method of the hydrolysis resistant continuous carbon fiber reinforced nylon 6 material. Compared with the prior art, the preparation method is reasonable in design, simple in operation and strong in practicability and adopts the continuous carbon fiber reinforced nylon 6 material so that the length of carbon fibers in a workpiece can be remained at 3-6mm, thereby the rigidity and the strength of the material are increased, the shock resistance and heat resistance of the material are obviously improved, and the material has long-term hydrolysis resistant stability and anti-chemical corrosion performance.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to a hydrolysis-resistant continuous carbon fiber reinforced nylon 6 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 6 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 6 with carbon fiber and glass fiber.
