Halogen-free anti-buckling-deformation reinforced nylon 6 and manufacturing process thereof

Abstract

The invention relates to an organic high polymer composite material, and more specifically relates to a halogen-free anti-buckling-deformation reinforced nylon 6 and a manufacturing process thereof. The halogen-free anti-buckling-deformation reinforced nylon 6 is composed of the following components in percentage by weight: 45-70% of nylon 6, 1-35% of halogen-free and alkali-free glass fiber, 1-40% of halogen-free glass microsphere, 1-5% of toughener, 0.1-0.4% of coupling agent and 0.1-5.5% of other assistants. According to the invention, the halogen-free anti-buckling-deformation reinforced nylon 6 and the manufacturing process thereof have the characteristics that the reinforced nylon 6 is halogen-free and environment-friendly and a good anti-buckling-deformation property is added on the basis of keeping favorable comprehensive mechanical properties, thereby being more suitable for the production of masks / shells required to be tightly assembled and molded parts such as product frameworks and the like; and both the production and the procurement are convenient. Thus, the comprehensive competitive power of the product is comprehensively improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a halogen-free anti-warping deformation reinforced nylon 6 and its manufacturing process. Background technique [0002] Nylon 6 is one of the most widely used engineering plastics. Its amide group is polar and has a strong hydrogen bond in its structure, which makes nylon 6 have a high melting point and good physical and mechanical properties. And wear resistance and self-lubricating properties, these comprehensive characteristics are not available in other plastics. However, the heat distortion temperature of pure nylon 6 is low, the water absorption is high, the impact strength before water absorption is low, the rigidity drops sharply after water absorption, and the size is unstable, which limits the application of nylon 6 and further reduces the downstream industry. Material selection for design engineers. Therefore, research on compound modification of ...

Problems solved by technology

Therefore, it has caused serious troubles to many export enterprises in my country.

At the same time, because glass fiber has a large aspect ratio, and nylon 6 is a crystalline material, it is easy to generate large internal stress during molding, resulting in warping and deformation of the finished product

[0003] At present, there are already anti-warping reinforced nylon 6 materials in the market, which use talcum powder to prevent warping, which has a series of disadvantages such as low strength, insufficient anti-warping effect, affecting the appearance of the product, and poor fluidity of the material.
