Environmentally friendly high heat dissipation titanium silver white appliance backplane

Abstract

This case involves an environment-friendly high heat dissipation titanium silver white home appliance backplane, which is provided with titanium silver white finish coating, heat dissipation connecting layer, titanium silver white pre-coating layer, first passivation layer, galvanized plate, second passivation layer from top to bottom. layer and titanium silver white back coating; titanium silver white fine coating includes: polyurethane resin, silver powder, zirconium carbide, titanium dioxide and surfactant; titanium silver white back coating includes: epoxy resin, zirconium powder, scandium oxide, titanium carbide and surface Active agent; heat dissipation tie layer includes: propylene-octyl acrylate copolymer, glycerol, octyl p-methoxybenzoate, nano-silver wire, and nano-nickel wire. In this case, through the improvement of the coating structure and coating formula of the home appliance backplane, the corrosion resistance, high heat dissipation and anti-aging characteristics of the backplane are increased, and it can still maintain a high coating performance in a humid environment or a large temperature difference for a long time. Layer bonding strength, high heat dissipation efficiency, no dust accumulation on the surface of the coating, no pulverization and cracking, and no blistering after long-term use.

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...

AI Technical Summary

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
