Problems solved by technology

At present, there are few coatings in the society that can simultaneously insulate, heat, conduct, and withstand high temperatures. People generally pay attention to the performance of coatings in terms of high temperature resistance and insulation, and often ignore the important performance of thermal conductivity.

Abstract

The invention provides a method for preparing a coating for high-voltage equipment, comprising the following steps: a. Mixing organosilicon prepolymer, epoxy resin and organic metal salt into a reaction kettle, heating for a period of time, adding a curing agent and stirring, and then Add an organic solvent and stir to obtain a modified silicone resin; b. Mix the polyurethane resin, base material and tertiary amine compound into a ball mill for grinding, then import it into a container, add a diluent for dispersion treatment, and then add a coupling agent and a disinfectant The foaming agent is heated and kept for heat preservation reaction to obtain a mixture 1; c, adding the modified silicone resin to the mixture 1, stirring, and standing to obtain a mixture 2; d, dehydrating the mixture 2. The preparation method of the invention is simple, has good anti-fouling, flame-retardant and insulating properties, and fully meets the performance index requirements of high-voltage equipment for protective coatings.

Description

technical field [0001] The invention belongs to the technical field of coatings for high-voltage equipment, and in particular relates to a preparation method for coatings for high-voltage equipment. Background technique [0002] At present, in some places where high-voltage electrical appliances are used, due to some subjective considerations and objective conditions (such as in order to save materials, reduce costs, etc.), the setting of some high-voltage electrical equipment does not meet the safety distance required by the standard, and its working environment is often polluted. It is relatively serious (mainly dust pollution), so pollution flashover accidents often occur in electrical equipment, and there are also some accidents (such as small animals such as snakes and rats) that cause short-circuit and grounding accidents. These subjective and objective reasons cause high-voltage electrical equipment to explode, The vicious cycle of lightning flashes, fires, destructio...
