Problems solved by technology

[0005] Although the above method reduces the shrinkage of the composite material, it also greatly reduces the mechanical properties of the composite material; and as a desiccant, chlorine salt has a large water absorption, and after adding it, the water absorption of the nylon composite material will be greatly increased. Dimensional stability of the product, even more prone to warping

Abstract

The invention relates to the technical field of nylon materials, in particular to a nylon composite material and a preparation method thereof, an injection molded part and a household appliance. The nylon composite material comprises a main material and an auxiliary agent, wherein the main material comprises nylon and glass fiber; the auxiliary agent comprises an anti-warping agent, and the anti-warping agent is an ethylene-potassium methacrylate copolymer and / or an ethylene-magnesium methacrylate copolymer. By adding the specific copolymer into the nylon composite material, crystallization after nylon molding can be remarkably reduced, the phenomenon of large-size shrinkage is avoided, and it is ensured that an injection molded part keeps good size stability in the storage or subsequent use process, and buckling deformation does not occur. The obtained nylon composite material not only has high strength, high rigidity and temperature resistance, but also has good dimensional stability; meanwhile, the obtained injection molding product is smooth and uniform in surface and attractive in appearance, and is very suitable for being applied to household electrical appliance products such as coffee pot bases and induction cooker bases.

Description

technical field [0001] The invention belongs to the technical field of nylon materials, and particularly relates to a nylon composite material and a preparation method thereof, an injection molded part and a household appliance. Background technique [0002] Nylon 6 is an engineering plastic with low melting point and wide processing temperature range. It is inexpensive and widely used. Compared with other engineering plastics, glass fiber reinforced nylon 6 has excellent mechanical properties (such as high strength, high modulus, high hardness) and better thermal properties (such as high heat distortion temperature). After adding glass fiber reinforcement, 0.45MPa The heat distortion temperature can reach 220℃. In view of its excellent mechanical properties and heat resistance, good oil and solvent resistance, it is very suitable for use in household electrical products, such as coffee pot bases, induction cooker bases and other products. [0003] Nylon 6 is a semi-crysta...
