Environment-friendly high-heat-dissipation titanium silver home appliance backing plate

Abstract

The invention relates to an environment-friendly high-heat-dissipation titanium silver home appliance backing plate. The environment-friendly high-heat-dissipation titanium silver home appliance backing plate is sequentially provided with a titanium silver fine coating, a heat-dissipation linkage layer, a titanium silver pre-coating, a first passivation layer, a galvanized plate, a second passivation layer and a titanium silver back coating from top to bottom; the titanium silver fine coating comprises polyurethane resin, silver powder, zirconium carbide, titanium dioxide and surfactants; the titanium silver back coating comprises epoxy resin, zirconium powder, scandium oxide, titanium carbide and the surfactants; the heat-dissipation linkage layer comprises propylene-ethyl hexyl acrylate copolymer, glycerin, p-methoxybenzoic acid essien ester, silver nanowires and nickel nanowires. According to the environment-friendly high-heat-dissipation titanium silver home appliance backing plate, due to the fact that improvements are conducted on the coating structure of the home appliance backing plate and the coating formula, the corrosion resistance, the high-heat-dissipation property and the anti-aging property of the backing plate are improved, high coating bonding strength can still be maintained for a long time in the damp environment or when the temperature difference is larger, the heat-dissipation efficiency is high, the surface of the coating is not prone to dirt retention, pulverization and cracking do not occur after long time use, and the bubbling phenomenon does not exist.

Description

technical field [0001] The invention relates to a backboard material for home appliances, in particular to an environment-friendly high heat dissipation titanium-silver white backboard for home appliances. Background technique [0002] With the rapid development of science and technology, the service life of home appliances has also been extended. Taking refrigerators as an example, the normal service life of the internal core component compressor is at least 10-15 years. Therefore, for a refrigerator, its The corresponding service life of all internal accessories should also be at least 10 years, otherwise the compressor, which is the main component, is not broken, but other small parts are damaged. When a home appliance enters the end of its life, its maintenance cost It is very high, and many people are unwilling to spend a large amount of money to repair an old home appliance. This makes many old home appliances discarded before they are completely scrapped, which invisi...

Problems solved by technology

The backplane of the prior art can only last for 3-5 years. This is mainly not because the quality of the base steel plate of the backplane is not good enough, but because the bonding strength of the coating on the surface is not high enough. Under the influence of moisture, dust, corrosion, etc., the surface of the coating begins to crack or even fall off, and after the coating falls off, the steel plate inside is exposed and begins to rust. With the damage of the protective layer of the back plate, the core components inside the appliance also It begins to suffer from various erosions, and the service life of home appliances begins to decline. Therefore, the importance of the backplane is self-evident
