preparation example Construction

[0022] The preparation method of graphene heat-dissipating anticorrosion coating comprises the following steps:

[0023] (1) Under normal temperature and pressure, fully stir and mix the resin, diluent and curing agent in proportion to ensure their uniformity;

[0024] (2) At normal temperature and pressure, add graphene, zinc powder, boron nitride, and aluminum oxide in proportion to the above-prepared resin mixture, stir and disperse at high speed for 2 hours to prepare a graphene heat-dissipating anti-corrosion coating.

[0025] Graphene heat dissipation and anticorrosion coatings are applied to transformer radiators. The prepared graphene heat dissipation coating is evenly coated on the surface of the transformer radiator by spraying, roller coating, and flow coating. Curing at room temperature for 3 days.

Abstract

The invention relates to the technical field of coatings, in particular to a graphene heat dissipation anticorrosive coating and a preparation method and application thereof. The graphene heat dissipation anticorrosive coating is prepared from, by mass, 40-55 parts of resin, 8-11 parts of a curing agent, 25-28 parts of a diluent, 1-20 parts of zinc powder, 2-5 parts of graphene, 2-5 parts of boronnitride and 4-10 parts of aluminum oxide. By utilizing the heat dissipation function of the graphene coating, the temperature of a transformer radiator is effectively lowered, and the heat dissipation and cooling effects are obvious. Physical shielding and conductivity of graphene are utilized to improve the corrosion resistance of the coating.

Description

technical field [0001] The invention relates to a coating, in particular to a graphene heat-dissipating anticorrosion coating, a preparation method and an application thereof. Background technique [0002] Transformer heat sink is an energy converter, it will lose energy itself, the greater the load current, the more energy it will consume, if it does not dissipate heat, it will directly affect the working efficiency and service life of the equipment, therefore, good heat dissipation conditions are its necessary. Among many heat dissipation materials, heat dissipation paint is not only convenient to prepare, economical and practical, but also has good adhesion and continuity. For ordinary coatings, its heat dissipation effect is not good, which greatly affects the application of coatings in radiator transformers. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a graphene heat-dissipating anticorrosion coati...
