Highlight anti-warping reinforced nylon PA66

Abstract

The invention discloses highlight anti-warping reinforced nylon PA66, and belongs to the technical field of high polymer materials. The highlight anti-warping reinforced nylon PA66 is prepared from the following raw materials in parts by weight: 50-55 parts of PA66 polyamide resin, 20-30 parts of glass fiber, 20-25 parts of glass beads, 1-3 parts of an anti-floating fiber agent, 0.02-0.5 part of an antioxidant 1098, 0.02-0.05 part of an antioxidant 626, 0.5-2 parts of a thermal stabilizing agent, 1-3 parts of a toughening agent and 0.5-2 parts of a lubricant. As all base materials are safe and environment-friendly raw materials, the highlight anti-warping reinforced nylon PA66 disclosed by the invention not only is smooth in surface and good in mechanical property, but also has the characteristics of small shrinkage rate, warping prevention, high rigidity and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to high-gloss anti-warping reinforced nylon PA66. Background technique [0002] PA66 is also called nylon 66; polyhexamethylene adipamide; English name: Polyamide 66, abbreviated as nylon 66. CAS number: 32131-17-2 Translucent or opaque milky white crystalline polymer, widely used in the manufacture of machinery, automobiles, chemical and electrical device parts. [0003] Conventional PA66 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 PA66 reinforcement 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, ...

Problems solved by technology

[0004] Conventional PA66 reinforcement material has a 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.

[0005] There are also similar anti-warping reinforced nylons in China, but most of the current formulations use aniline black organic black dyes to dye black glass fibers and fill them to achieve a high-gloss effect, which is only effective for black products.
