Embodiment Construction

[0032] The invention provides a granular composite material containing metal fibers and a manufacturing method thereof. In particular, the metal fibers in the composite material are separated by polymer materials, and the metal fiber is a material with high surface conductivity. metal fibers. The granular composite material according to the present invention can be directly used as a raw material for molding plastic objects. During the molding of plastic objects, the metal fibers can be easily dispersed uniformly and the overlapping phenomenon is obvious. The application of the granular polymer composite material of the present invention can achieve reasonable antistatic and EMI shielding effects under the condition of low metal fiber content.

[0033] Please refer to Figure 2A and Figure 2B , Figure 2A and Figure 2B Disclosed is the morphology of a granular polymer composite material 20 according to a preferred embodiment of the present invention. Such as Figure 2A...

Abstract

A granular polymer composition contains a bundle of metallic fibres parallel to each other, the first high-molecular material used as the first coated layer of each metallic fibre, and the second high-molecular material used as the second coated layer of each metallic fibre. It car be used as the raw material of plastic objects for low cost and higher antistatic and electromagnetic sheiding effect.

Description

technical field [0001] The present invention relates to a granular polymer composite containing metal fibers and a manufacturing method thereof, and to a plastic article made of the granular composite material as a molding raw material ). Background technique [0002] The casings of current electronic products and instruments are mostly made of polymer materials such as ABS, PU, ​​PVC, PC, PC+ABS, nylon (Nylon), resin, rubber, etc., in order to achieve the purpose of light weight and low price . However, as antistatic and electromagnetic interference shielding (EMI shielding) requirements for electronic products and instruments are becoming more and more stringent, metal foils, such as copper foils or aluminum foils, are generally pasted inside the casing. Obviously, the above-mentioned prior art is time-consuming and greatly increases the manufacturing cost of electronic products and instruments. [0003] In order to shorten the manufacturing time and reduce the manufact...
