Problems solved by technology

[0003] The finished product produced by the multi-arc plasma coating process in the prior art also has the problems of large color difference of the coating and poor interface bonding force
In addition, the bathroom products widely used in the bathroom field are all made by water electroplating process, which causes serious water pollution, and this process is gradually eliminated. The problem of various performance deterioration under the environment conditions, ordinary vacuum coating process can not solve the problem of coating stability under long-term use conditions, not resistant to salt spray, easy to foam, rust, crack, paint film peeling and other phenomena

Description

technical field [0001] The invention belongs to the field of coating primers for bathroom products, and more specifically relates to a multi-arc coating electroplating primer and a preparation method thereof. Background technique [0002] UV vacuum electroplating coating is a new type of ultraviolet curing coating developed on the basis of UV plastic coating. With the development of plastic decoration technology, a metallized decoration technology for plastic products has emerged. It uses a plastic substrate to coat a primer, then vacuum electroplating or sputtering, and then coats a layer of metal film, and then coats the surface. Painted. The painted plastic surface is completely shimmering with metallic luster, showing a noble and magnificent metal quality, and it cannot be seen as a plastic product at all. The multi-arc plasma coating process refers to the use of titanium, zirconium, chromium and other targets in a certain vacuum state on the vacuum coating equipment, ...
