Problems solved by technology

[0004] Conventional PA66 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 product surface, 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-warping toughened nylon PA66 / PC alloy. Background technique [0002] PA66 (polyamide resin) is also known as nylon 66; Chinese name: polyhexamethylene adipamide; English name: Polyamide 66, abbreviation nylon 66, translucent or opaque milky white crystalline polymer, widely used in the manufacture of machinery, automobiles, Parts for chemical and electrical installations. [0003] Conventional PA66 as an engineering plastic is generally reinforced with glass fiber, the purpose is to improve the material's impact strength, tensile strength, flexural modulus, flexural strength, and reduce shrinkage to meet industrial use. [0004] Conventional PA66 reinforced materials have good rigidity. Generally, 10-50% of glass fiber is added. Due to the arrangement of glass fibers and the shrinkage of the finished product, it is easy to cause unevenness of the product, floa...
