Description
一种防静电复合材料、 电子设备壳体以及电子设备 技术领域 Anti-static composite material, electronic device housing and electronic device
本发明涉及复合材料领域, 具体涉及一种防静电复合材料、 由该防静电复 合材料制成的工件、 电子设备壳体以及电子设备。 背景技术 The present invention relates to the field of composite materials, and in particular to an antistatic composite material, a workpiece made of the antistatic composite material, an electronic device housing, and an electronic device. Background technique
防爆对讲机是指可以工作在爆炸性气体环境中的对讲机。与普通对讲机相 比,防爆对讲机的很多部件都需要进行特别的设计以防止在在爆炸气体环境中 使用时产生危险。 例如, 对讲机的机器表面通常需要进行防静电处理, IEC60079-0 2007中规定, 防爆对讲机的机器表面电阻应当小于 。 Explosion-proof walkie-talkie refers to a walkie-talkie that can work in an explosive atmosphere. Many components of explosion-proof walkie-talkies require special design to prevent hazards when used in an explosive atmosphere, as compared to conventional walkie-talkies. For example, the surface of the walkie-talkie machine usually needs to be anti-static. The surface resistance of the explosion-proof walkie-talkie should be less than that specified in IEC60079-0 2007.
现有技术中,对于防爆对讲机的机器表面的防静电处理一般有以下三种方 法, 分别是: 使用金属外壳作为对讲机的壳体; 使用普通的塑料外壳, 但在塑 料外壳表面喷涂一层防静电涂层; 或者,使用填充有导电填料的树脂组合物制 成防静电塑料来使机器表面达到防静电的效果。但是,现有技术中使用的上述 三种方法都有其自身难以克服的缺点。 In the prior art, the anti-static treatment of the machine surface of the explosion-proof walkie-talkie generally has the following three methods, namely: using a metal casing as the casing of the walkie-talkie; using a common plastic casing, but spraying an anti-static layer on the surface of the plastic casing Coating; Alternatively, an antistatic plastic is made using a resin composition filled with a conductive filler to achieve an antistatic effect on the surface of the machine. However, the above three methods used in the prior art have disadvantages that are difficult to overcome by themselves.
目前, 防爆对讲机的金属外壳一般是不锈钢材质或铝 /镁合金材质的外壳, 金属外壳需要与内部器件进行绝缘处理,而由于对讲机的机器外壳形状比较复 杂, 因此不锈钢材质的外壳成型加工比较困难; 铝 /镁合金的主要问题是不符 合防爆的安全要求 (因为棵露的铝合金或镁合金比较容易产生火花, 参见 IEC60079-0 2007 ), 而表面再喷涂油漆又不满足电阻的要求。 当使用普通塑料 作为对讲机的外壳, 表面喷涂防静电涂层时, 在防爆对讲机的使用过程中, 防 静电涂层容易磨损, 此时也难以满足防静电的要求, 容易产生危险。 与上述两 种方法相比,使用填充有导电填料的树脂组合物来制备防爆对讲机的壳体是目 前比较流行的技术,通常使用的导电填料是碳材料、导电金属材料或其他有机 的导电剂。但该种工艺的主要问题是, 由于导电填料的添加量对于材料的韧性 具有重要的影响, 因此当需要精确控制电阻率的时候, 不能很好的平衡材料的 韧性和刚性, 材料要么偏脆, 要么偏软, 对于通讯设备的外壳不适用。
发明内容 At present, the metal casing of the explosion-proof walkie-talkie is generally made of stainless steel or aluminum/magnesium alloy. The metal casing needs to be insulated from the internal components. However, due to the complicated shape of the machine casing of the walkie-talkie, it is difficult to shape the casing of stainless steel. The main problem with aluminum/magnesium alloys is that they do not meet the safety requirements for explosion protection (because the exposed aluminum or magnesium alloys are more prone to sparks, see IEC 60079-0 2007), and the surface repainting does not meet the resistance requirements. When ordinary plastic is used as the outer casing of the walkie-talkie and the surface is sprayed with anti-static coating, the anti-static coating is easy to wear during the use of the explosion-proof walkie-talkie. At this time, it is difficult to meet the requirements of anti-static, and it is easy to cause danger. Compared with the above two methods, the use of a resin composition filled with a conductive filler to prepare an explosion-proof walkie-talkie housing is a relatively popular technique, and a commonly used conductive filler is a carbon material, a conductive metal material or other organic conductive agent. However, the main problem of this process is that since the addition amount of the conductive filler has an important influence on the toughness of the material, when the electrical resistivity needs to be precisely controlled, the toughness and rigidity of the material are not well balanced, and the material is either brittle or not. Either soft, not suitable for the outer casing of communication equipment. Summary of the invention
