NOVELTY - The anti-static composite fabric comprises base fabrics and composite base materials. The base fabric includes pure cotton fiber and viscose fiber. The composite base material includes: 2.10-2.60 wt.%, preferably 2.35 wt.% antistatic agent, 0.56-0.84 wt.%, preferably 0.70 wt.% nano-silica, 0.42-0.64 wt.%, preferably 0.53 wt.% graphene nanosheets, 0.63-0.77 wt.%, preferably 0.70 wt.% nano boron nitride, 19.20-21.10 wt.%, preferably 20.15 wt.% carbon fiber, 34.20-35.30 wt.%, preferably 34.75 wt.% epoxy resin, and 40.82 wt.% organic solvents. USE - Carbon fiber-based anti-static composite fabric used in petroleum industry, mining and metallurgy industry, chemical industry, electronic industry and special industry. ADVANTAGE - The anti-static composite fabric can effectively improve the antistatic performance based on the base material ant-static performance, and the safety performance is higher. The fabric has nano thickness, easy to be uniformly compounded with other materials such as polymer material, and forms a good composite interface. The effective nano material is dispersed in the composite surface material, which can improve the anti- static performance of the composite fabric. The nanometer boron nitride is easy to absorb moisture, and the quality is light, which can effectively enhance the surface water absorbing performance of composite fabric, thus forming a micro water film on the surface of fabric. The anti-static composite fabric is further strengthened. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of a carbon fiber-based antistatic composite fabric, which involves (1) weighing antistatic agent, nano-silica, nanometer graphene sheet, nano boron nitride, carbon fiber, epoxy resin and organic solvent, (2) mixing, stirring and heating the antistatic agent with one-third weight of carbon fiber, epoxy resin and organic solvent, carrying ultrasonic vibration treatment for 50-60 minutes to obtain a mixed base material, (3) mixing, stirring and heating one-half by weight of nano-silicon oxide, nano-graphene sheet and nano-boron nitride and one-third by weight of carbon fiber, epoxy resin and organic solvent, carrying out ultrasonic vibration treatment for 50-60 minutes to obtain a composite modified base material, (4) mixing, stirring and heating remaining nano-silica with one-ninth weight of carbon fiber, epoxy resin and organic solvent, carrying out ultrasonic vibration treatment for 20-30 minutes to obtain modified base material A, (5) mixing, stirring and heating remaining nano-graphene sheets with one-ninth parts by weight of carbon fiber, epoxy resin and organic solvent, carrying out ultrasonic vibration treatment for 20-30 minutes to obtain modified base material B, (6) mixing, stirring and heating remaining nano-boron nitride with the remaining carbon fibers, epoxy resin and organic solvent, carrying out ultrasonic vibration treatment for 20-30 minutes to obtain modified base material C, (7) mixing, high-speed stirring and heating the mixed base material, the composite modified base material, the modified base material A, the modified base material B, and the modified base material C, carrying out ultrasonic vibration treatment for 70-80 minutes to obtain a composite base material, and (8) spraying and compounding the composite base material on the base fabric, and performing drying and cooling treatment.
