Problems solved by technology

The disadvantage of this kind of distribution box is that the insulation performance is not good, and it will cause serious safety hazards when the line is short-circuited, and the product is relatively heavy and inconvenient to install.
In recent years, plastic distribution box shells have been researched, which have good insulation performance and small weight, but poor mechanical properties, corrosion resistance and thermal conductivity, which are likely to bring safety hazards

Abstract

The invention discloses a heatproof and anticorrosive coating for a power distribution cabinet shell, a preparation method thereof, and the power distribution cabinet shell. The coating comprises organosilicon epoxy resin polymer, polyurethane resin, novolac epoxy resin, nanometer cerium oxide, graphene, calcined kaolin, modified zeolite powder, rutile titanium dioxide, expanded perlite, an ethylene-tetrafluoroethylene copolymer, nanometer titanium dioxide, mica powder, glass beads, ammonium triphosphate, a leveling agent and a solvent. The coating has an extremely high thermal stability, extremely high corrosion resistance and strong surface adhesion, and is applied to the surface of the power distribution cabinet shell in order to greatly improve the heat and corrosion resistance of thepower distribution cabinet shell and improve the use safety of a power distribution cabinet.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-resistant and corrosion-resistant coating for a distribution cabinet shell, a preparation method of the coating, and a distribution cabinet shell coated with the coating. Background technique [0002] The distribution box is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then the low-voltage side of the transformer is stepped down to lead to low-voltage The distribution box and the low-voltage distribution box are connected to each power distribution panel, control box, and switch box. Inside, some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices are assembled into one The equipment of the power distribution device that meets the design function requirement...
