Preparation method of novel conductive exothermic carbon fiber composite material

Abstract

The invention relates to a preparation method of a novel conductive exothermic carbon fiber composite material. The composite material is prepared by using a material tank, a fluffer, a blower, a gyrator, a sedimentation adjuster, a conveyer belt, a negatively charged substrate, a hot air drying device, a calendering and trimming roller, a fiber composite material and a recoverer. The preparation method comprises the steps that: air is used as a medium, and carbon fiber is chopped into 3-11 millimeters, dried at 100 DEG C for 60 minutes, conveyed to the material tank and primarily dispersed by the fluffer; the treated carbon fiber is conveyed to the gyrator by the blower for further dispersion, the sufficiently dispersed carbon fiber is quantitatively conveyed to the conveyer belt by the sedimentation adjuster with a positive electric field, and the positively charged carbon fiber is adsorbed to the surface of the negatively charged substrate under the action of electrostatic field force; and the carbon fiber is dried by the hot air drying device, and coiled by the calendering and trimming roller to obtain the fiber composite material, and excessive carbon fiber is recovered by the recoverer for reutilization during compounding. The novel conductive exothermic carbon fiber composite material has the characteristics of high-temperature resistance, flame retardancy, disassembly resistance, high strength and the like, and is suitable for industrial and civil warming and heat insulation, heating and medical care as well as antistatic materials.
