Problems solved by technology

However, because the glass fiber directly enters the twin-screw of the extruder from the fiber feeding port, the shearing in the screw increases, and the length of the glass fiber in the product becomes shorter, which greatly reduces the impact toughness and rigidity of the material.

Abstract

The invention discloses a high-flowability long glass fiber reinforced nylon 6 material. The high-flowability long glass fiber reinforced nylon 6 material is prepared by the following ingredients in parts by weight: 500-700 parts of high-flowability nylon 6, 300-500 parts of continuous glass fiber, 6-10 parts of antioxidant, 4-8 parts of lubricant, and 3-6 parts of compatilizer. The high-flowability long glass fiber reinforced nylon 6 material has higher rigidity and strength, as well as excellent impact resistance property, the surface appearance of injection-moulded parts is good, the material can be directly formed by injection moulding, the production efficiency is high, and the used parts can be recycled after being ground.

Description

[0001] technical field [0002] The invention relates to the technical field of polymer materials, in particular to a high-fluidity long glass fiber reinforced nylon 6 material and a preparation method thereof. Background technique [0003] Polyamide resin is a chemical raw material with excellent performance and wide application. Because of its non-toxic, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, it is widely used to replace copper and other metals in machinery and chemical industry. Manufacture of bearings, gears, pump blades and other parts in industries such as instrumentation, automobiles, etc., but in some parts with relatively high strength requirements, especially in the military and aerospace fields, nylon 6 raw materials are difficult to meet their use requirements, and its During use, due to water absorption, size deformation occurs. To solve this problem, domestic and foreign enterprises have reinforced and modifi...
