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. Raw materials include, by weight, 100 parts of nylon-610, 30-70 parts of nylon-6, 1-5 parts of an antioxidant, 1-5 parts of a lubricant, 1-5 parts of coupling agents, 30-100 parts of long glass fiber, and 70-450 parts of short glass fiber. According to the material formula, in the ultra-high filled composite material, the lubricant comprises a dendritic type nylon lubricant which can greatly reduce material degradation caused by shear heat, the compound of the dendritic nylon lubricantand zinc stearate has a strong complementation effect, use of the coupling agents can reduce floating fiber, and thus, mechanical performance of the composite material can be improved greatly.

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.
