Problems solved by technology

[0004] Conventional PA6 reinforced material has good rigidity effect, and generally adds 10-50% of glass fiber. Due to the arrangement of glass fiber and the shrinkage of the finished product, it is easy to cause uneven products, floating fibers on the surface of the product, and poor surface of the product, which cannot meet the use of high-demand products. At the same time, the reinforced nylon surface has poor smoothness and high density
[0005] PC (polycarbonate) is a high molecular polymer containing carbonate groups in the molecular chain. It has excellent characteristics such as good rigidity, good toughness, small shrinkage rate and stable size, but the internal stress is large, and the surface is not wear-resistant and easy to scratch

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss anti-warpage nylon PA6 / PC alloy. Background technique [0002] PA6 (polyamide resin) is also known as nylon 6; English name: Polyamide 6, abbreviated nylon 6; translucent or opaque milky white crystalline polymer, widely used in the manufacture of machinery, automobiles, chemical and electrical device parts. [0003] Conventional PA6 is used as an engineering plastic and is generally reinforced with glass fiber. The purpose is to improve the impact strength, tensile strength, flexural modulus, flexural strength, and reduce shrinkage of the material to meet industrial use. [0004] Conventional PA6 reinforced material has good rigidity effect, and generally adds 10-50% of glass fiber. Due to the arrangement of glass fiber and the shrinkage of the finished product, it is easy to cause uneven products, floating fibers on the surface of the product, and poor pr...
