Abstract

The invention relates to a water-based easy-to-radiate antibacterial insulating coating and a preparation method thereof. The coating comprises the following components: water-based resin, ethylene glycol butyl ether, hydrogen bentonite, a maleic anhydride copolymer, polysiloxane, polyether modified dimethyl siloxane, a polyurethane leveling agent, an antibacterial agent, mica powder, boron nitride, glass glaze powder and water, and the water-based easy-to-radiate antibacterial insulating coating is prepared through a certain process. The product disclosed by the invention has excellent insulativity (high dielectric strength, low dielectric loss and high volume resistivity); the coating has good heat conductivity and antibacterial property, effectively solves the problems of poor heat dissipation and insulation of electronic devices, wires, cables and other materials, improves the precision, reduces the energy loss, prolongs the service life, prevents the paint film from mildewing, andis environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based heat-dissipating antibacterial insulating paint and a preparation method thereof. Background technique [0002] With the gradual popularization of 5G commercial use, the input power of related materials such as electronic devices, wires and cables has been greatly increased, and these materials have been working for a long time and the working environment is closed, resulting in very high internal temperature, which greatly reduces the temperature. The performance and heat dissipation of these devices restrict their development. Insulating coatings can not only make the surface of equipment non-conductive and reduce the incidence of accidents, but also improve its precision, reduce energy loss and prolong its service life. However, the thermal conductivity of insulating coatings on the market is poor, and the insulation properties of easy-to-dissipate coa...
