Problems solved by technology

For example, for mobile phones, the material requirements range from ABS to PC / ABS alloy, then to PC, and then to metal. The strength of the material is continuously enhanced, and the appearance becomes more and more beautiful. However, when using metal as the shell, the material is difficult to form and the production cost is very high. , and metal materials have a shielding effect on electromagnetic waves, the use of metal materials has certain limitations on the design of the appearance

Abstract

The invention discloses a high-rigidity metal-like nylon composite material and a preparation method thereof. The raw materials include the following components in parts by weight: nylon 610 100; nylon 6 30-70; antioxidant 1-5; lubricant 1-5 ; Coupling agent 1‑5; Long glass fiber 30‑100; Short glass fiber 70‑450. In terms of material formulation of the present invention, the ultra-highly filled composite material includes dendritic nylon lubricant in the lubricant, which can greatly reduce the material degradation caused by shear heat. In addition, dendritic nylon lubricant and zinc stearate The combination of the two can play a strong complementary effect. The use of the formula coupling agent can reduce the floating fiber and greatly improve the mechanical properties of the material.

Description

technical field [0001] The invention belongs to the technical field of engineering materials, and in particular relates to a high-rigidity metal-like nylon composite material and a preparation method thereof. Background technique [0002] In the field of consumer electronics, people have higher and higher requirements for the appearance and texture of materials. People not only require various functions of products, good appearance, and heavy sense of metal. For example, for mobile phones, the material requirements range from ABS to PC / ABS alloy, then to PC, and then to metal. The strength of the material is continuously enhanced, and the appearance becomes more and more beautiful. However, when using metal as the shell, the material is difficult to form and the production cost is very high. , and metal materials have a shielding effect on electromagnetic waves, the use of metal materials has certain limitations on the design of the appearance.
