Problems solved by technology

The power of the components in the power distribution cabinet is high, and the effective heat dissipation area is small, resulting in an increase in heat generation per unit area. The mechanical, chemical, and electrical problems caused by this thermal drive may seriously affect the quality and reliability of the components.
[0004] In order to protect the surface of the power distribution cabinet, the surface is coated with paint. However, the paint used in the prior art has poor heat dissipation, which leads to temperature accumulation in the power distribution cabinet and affects the heat dissipation effect of the power distribution cabinet.

Abstract

The invention discloses a preparation process of a heat dissipation paint for a power distribution cabinet. The method relates to the technical field of power distribution cabinets and comprises the following steps: (1) obtaining sericite powder dispersion liquid; (2) obtaining a composite microchip; (3) obtaining composite dispersion liquid; (4) obtaining an aged composite material; (5) obtaining stirred slurry; and (6) adding the stirred slurry into a ball mill to carry out ball milling treatment, and thus obtaining the product after the ball milling treatment is completed. A coating formed by the heat dissipation coating prepared by the method has a higher heat conductivity coefficient, and the heat dissipation performance of the coating can be greatly improved by introducing the prepared aged composite material.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, in particular to a preparation process of heat-dissipating paint for power distribution cabinets. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] ...
