Problems solved by technology
However, the main problem of this process is that since the amount of conductive fillers has an important impact on the toughness of the material, when the resistivity needs to be precisely controlled, the toughness and rigidity of the material cannot be well balanced, and the material is either brittle or brittle. Either it is soft and not suitable for the shell of communication equipment

Abstract
The invention provides an antistatic composite material which comprises an antistatic layer and an insulating support layer, wherein the antistatic layer is prepared by curing a first resin composition, and the first resin composition contains conductive fillers; and the insulating support layer is connected with the antistatic layer, and prepared by curing a second resin composition. Compared with the prior art, the antistatic layer of the composite material provided by the invention can enable the composite material to achieve a good antistatic effect, and the insulating support layer can enable the composite material to have good mechanical properties, namely, by using the composite material provided by the invention, the good mechanical properties of the composite material are guaranteed, and the composite material is endowed a good antistatic property.
Description
technical field [0001] The invention relates to the field of composite materials, in particular to an antistatic composite material, a workpiece made of the antistatic composite material, an electronic equipment shell and electronic equipment. Background technique [0002] Explosion-proof walkie-talkies refer to walkie-talkies that can work in explosive gas environments. Compared with ordinary walkie-talkies, many parts of explosion-proof walkie-talkies need to be specially designed to prevent danger when used in explosive gas environments. For example, the machine surface of the walkie-talkie usually needs anti-static treatment. According to IEC60079-02007, the surface resistance of the explosion-proof walkie-talkie should be less than 1GΩ. [0003] In the prior art, there are generally the following three methods for the anti-static treatment of the machine surface of the explosion-proof walkie-talkie, namely: using a metal shell as the shell of the walkie-talkie; using a...
