Problems solved by technology

[0002] In the field of power infrastructure, some equipment will generate heat during operation. If the heat is not dissipated in time, it will affect the normal operation of the equipment and even cause safety accidents; for example, the power compensation cabinet is a common cabinet, and its main function is to compensate The reactive power in the power system where it is located, for this reason, is equipped with a large number of capacitive and inductive components inside, resulting in a large amount of heat dissipation during the operation of the compensation cabinet, and a reactor can reach 60 during operation. Above ℃, the general high-power compensation cabinet is equipped with two fans for heat dissipation; but the heat dissipation and speed can no longer lower the overall temperature of the compensation cabinet, and the heat is concentrated in the reactor area, which is difficult to disperse

Abstract

The invention provides a heat conduction coating with high heat conductivity. A preparing process includes the following steps that 1, modification acrylic resin emulsion is prepared; 2, binary acid and dihydric alcohol are mixed, heated and subjected to a condensation reaction under protection of argon, and polyester resin is obtained; 3, the modification acrylic resin emulsion, the polyester resin, titanium oxide sol, glass fibers, pigment, wetting agents, dispersing agents and defoaming agents are mixed and then evenly dispersed, and the heat conduction coating is obtained. The heat conduction coating with the high heat conductivity has the advantages of being good in adhesive force and heat conductivity; after the heat conduction coating is sprayed to the surfaces of heat-emitting electric facilities, heat dissipation efficiency can be improved.
