Problems solved by technology

[0003] For example, the shells of many precision instruments require electromagnetic shielding. The existing shielding generally uses metal shells as electromagnetic shielding shells. Although metal shells have electromagnetic shielding functions, the processing is more complicated, the cost is high, and the weight is heavy. In addition, its shape is not easy to shape. , not suitable for precision instruments
The traditional plastic shell can give people a satisfactory appearance but has no electromagnetic shielding function.

Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0018] refer to figure 1 , electromagnetic shielding plastic, including a plastic matrix 1, embedded in the plastic matrix 1 with a conductive fiber layer 2, the conductive fiber layer 2 is a fiber layer made of conductive fibers.

[0019] The plastic base 1 can be made of PVC, which has the characteristics of corrosion resistance and high mechanical strength. The plastic matrix 1 can also use resin-based composite materials, such as BMC resin-based composite materials. BMC resin-based composite materials have excellent electrical and mechanical properties, heat resistance, and chemical corrosion resistance, and are suitable for various molding processes. Another example is SMC resin-based composite materials. SMC resin-based composite materials hav...

Abstract

The invention relates to plastic, in particular to electromagnetic shielding plastic, comprising a plastic base body, wherein a conductive fiber layer is embedded in the plastic base body and is a fiber layer made of conductive fibers. The electromagnetic shielding plastic adopting a structure with the conductive fiber layer added into the plastic base body has the advantages of light weight, easy processing and low cost in comparison with the traditionally common metal casings. By adopting the technical scheme, the invention not only has the characteristic of easy forming of plastic products, but also has the characteristic of the electromagnetic shielding radiation resistance which is equipped by conductive materials.

Description

technical field [0001] The invention relates to plastics, in particular to a plastic with electromagnetic shielding function. Background technique [0002] With the development of modern science and technology and the wide application of modern electronics and communication technologies, in order to prevent information leakage and interference, the number of objects requiring electromagnetic shielding is increasing, and the degree of shielding is increasing. The time and space requirements for shielding increasing day by day. [0003] For example, the shells of many precision instruments require electromagnetic shielding. The existing shielding generally uses metal shells as electromagnetic shielding shells. Although metal shells have electromagnetic shielding functions, the processing is more complicated, the cost is high, and the weight is heavy. In addition, its shape is not easy to shape. , not suitable for precision instruments. The traditional plastic shell can give ...
