Preparation method for epoxy cast resin of alternating current high-voltage sleeve

The invention discloses a preparation method for epoxy cast resin of an alternating current high-voltage sleeve. According to the method, a large amount of powdered filler is added, and the processing of raw materials is convenient, so that the resin cost is lowered; the mechanical property and the conductivity of resin are greatly improved; furthermore, the adopted raw materials are non-toxic, cannot be volatilized and are green and environment-friendly; by adoption of cycloaliphatic epoxide resin, a product is extremely high in weather resistance and dielectric property. The alternating current high-voltage sleeve prepared from the cast resin prepared by the preparation method is extremely high in impact strength, electrical strength and flame retardancy, is also excellent in conductivity, and can meet the requirement on the performance of alternating current high-voltage sleeve equipment; moreover, due to the extremely low content of volatile substances, the use safety and the environment friendliness of the epoxy cast resin are guaranteed; the epoxy cast resin can be widely used in the field of electrical equipment.
