Abstract

The invention discloses a novel high-insulation polymer composite material. The novel high-insulation polymer composite material is characterized by comprising the following components: resin, composite fibers, electronic cloth and an additive, the composite fibers comprise glass fibers and basalt fibers. The preparation method of the novel high-insulation polymer composite material comprises the following steps: (S1) preparing raw materials; (S2) resin mixing: adding nano rare earth particles and an additive into the molten resin, and mixing to obtain mixed resin; (S3) composite fiber impregnation: conveying the composite fibers into an impregnation tank containing mixed resin through a winding and unwinding device; (S4) curing the resin to obtain a composite fiber reinforcement prepreg; (S5) arranging a pressing die; and (S6) heating and pressing the pressing die to obtain a finished product. The insulating property and the mechanical property of the material are improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an insulating polymer composite material, especially a novel strong insulating polymer composite material and a preparation method thereof. Background technique [0002] Power equipment is inseparable from insulating materials. At present, the main materials involved in power equipment are still composed of short fiber epoxy glass fiber or ceramic fiber components. Ceramic fiber components have problems such as heavy weight and easy corrosion. Epoxy glass fiber is easy to corrode, Problems such as weak wind resistance, low strength, and easy aging lead to technical pain points such as complex manufacturing processes, difficulty in ensuring insulation, high maintenance costs, and short service life. In general, the electrical materials in the prior art have unsatisfactory insulating properties and other comprehensive strengths of the materials. SUMMARY OF THE INVENTI...
