Title:
ULTRAHIGH-VOLTAGE-RESISTANT INSULATING RESIN AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/206652
Kind Code:
A1
Abstract:
Provided are an ultrahigh-voltage-resistant insulating resin and a preparation method therefor. The method comprises the following steps: mixing 40-68 parts of matrix resin and 5-15 parts of toughening agent, and stirring the mixture at 60-100 °C for 1-3 h under an inert gas atmosphere to obtain a toughened matrix resin; performing ball milling on 10-35 parts of ceramic additive and a solvent to obtain a ceramic additive dispersion liquid; stirring the ceramic additive dispersion liquid, the toughened matrix resin, 10-25 parts of silane, and 3-8 parts of dispersant at room temperature for 2-3 h to obtain a mixture; performing reduced pressure distillation on the mixture to remove the solvent to obtain a silane-modified toughened matrix resin; and adding 0.5-3 parts of accelerant to the silane-modified toughened matrix resin, and uniformly stirring the mixture to obtain the ultrahigh-voltage-resistant insulating resin. The prepared ultrahigh-voltage-resistant insulating resin has excellent thermal, mechanical, and electrical insulating properties.
