Insulating coating for high-voltage electrical apparatus and preparation method of coating

Abstract

The invention discloses an insulating paint for high-voltage electrical appliances, which comprises the following components by weight: 60-80 parts of epoxy resin, 30-40 parts of silicone rubber, 20-30 parts of thermosetting resin, 15-35 parts of carbonic acid resin, 10-30 parts of nano-montmorillonite, 10-20 parts of talcum powder, 5-15 parts of light calcium carbonate, 3-8 parts of titanium dioxide, 5-10 parts of organic solvent, 2-8 parts of amino polyamide, 5 parts of nano-titanium dioxide ‑10 parts, calcium chloride 5‑15 parts, composite flame retardant 8‑15 parts and crosslinking agent 3‑8 parts. The insulating paint for high-voltage electrical appliances of the invention has good flame-retardant and insulating properties, thereby solving the problem of safety protection of high-voltage electrical equipment.

Description

Technical field [0001] The invention relates to the technical field of coatings for safety protection, in particular to a high-voltage electrical appliance insulating coating and a preparation method thereof. Background technique [0002] At present, in some places where high-voltage electrical appliances are used, due to certain subjective considerations and objective constraints (for example, to save materials, reduce costs, etc.), some high-voltage electrical equipment does not meet the safety distance required by the standard, and the working environment is often polluted. More serious, so that electrical equipment often has pollution flashover accidents, and some accidents (such as snakes, rats and other small animals) caused short-circuit and grounding accidents. These subjective and objective reasons cause high-voltage electrical equipment to explode, flash fire, and destroy electrical appliances. The vicious circle of equipment and power outages has caused great losses an...

Problems solved by technology

[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 more serious, so pollution flashover accidents often occur in electrical equipment, and there are also short-circuit and grounding accidents caused by accidents (such as small animals such as snakes and rats). The vicious cycle accidents of equipment and power outages cause great losses and disasters to people's lives and production and construction

[0003] Therefore, the safety protection of high-voltage electrical equipment has become an anxious and urgent problem for many enterprises and departments. Recently, some enterprises have tried to develop coatings for the safety protection of electrical equipment, but the effect is not satisfactory.
