Title:
CORONA-RESISTANT MICA/ARAMID FIBER COMPOSITE MATERIAL FOR NEW-ENERGY VEHICLES AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/082973
Kind Code:
A1
Abstract:
A corona-resistant mica/aramid fiber composite material for new-energy vehicles and a preparation method therefor. Preparation raw materials comprise a modified aramid fiber material, an adhesive, and a modified mica material; the modified mica material comprises mica powder, a hydrochloric acid solution, ethanol, a silane coupling agent, methyl methacrylate, an initiator, and methylbenzene; the mica powder is composed of first mica powder, second mica powder, and third mica powder, the particle size of the first mica powder is 90-110 μm, the particle size of the second mica powder is 130-150 μm, and the particle size of the third mica powder is 200-230 μm; and the weight ratio of the first mica powder to the second mica powder to the third mica powder is 1:(3-5):(3-5). The modified aramid fiber material and the modified mica material are compounded by using the adhesive, so that the overall compactness, the interpolated paper manufacturability, the corona resistance, the PDIV, and the temperature resistance level of the composite material are improved, and the material can significantly improve the electrical insulation performance and the long-term safe operation life of new-energy vehicles.
