According to the anti-static aggregation polytetrafluoroethylene material for the dust-free workshop provided by the invention, the conductivity of polytetrafluoroethylene is improved mainly by adding the carbon black, so that dust adsorption caused by charge accumulation is prevented. Specifically, in the method, a layer of metal salt component is settled on the surface of a mixture of carbon black and polytetrafluoroethylene in a surface settling manner, and the salt component is wrapped on the surface of polytetrafluoroethylene in a microwave shaping manner, so that a stable system is formed. And when the carbon black expands, gap supplement is carried out, so that the situation that in the melting process, the carbon black is gathered, the resistivity change of the material is large, the local gathering effect of charges is formed, and dust accumulation is aggravated is prevented. 本发明提供了一种用于无尘车间的防静电集聚的聚四氟乙烯材料，其中主要通过炭黑的添加来提升聚四氟乙烯的导电能力，从而防止电荷的堆积导致的粉尘吸附。具体而言，本方法中采用表面沉降的方式，在炭黑和聚四氟乙烯的混合物的表面沉降一层金属盐成分，并通过微波定型的方式
