Problems solved by technology

[0002] Traditional anti-fouling materials are prepared by washing-magnetic control (PVD) process. The disadvantage of this process is that the anti-fouling effect is not long-lasting, and it is easy to lose its anti-fouling effect under the influence of external forces such as hot water cooking, steel wool, and rubber wear. dirty effect
For example, in mobile phones, notebooks and other products that require relatively high anti-pollution appearance, consumers' living habits are prone to lipstick / hand cream / sunscreen oil / cola and other products are easy to touch the surface of the product, causing pollution to the appearance of the product and affecting users perception of
In addition, in the coating process, because the traditional process cannot be selectively sprayed from multiple angles, some workpieces with irregular shapes cannot form a uniform and dense surface coating, which means that some corners of some irregular products that cannot be sprayed uniformly cannot guarantee effective coating. Anti-fouling effect, after long-term use, the anti-fouling effect will be lost

Abstract

The invention provides a nano antifouling coating used for 3C electronic field, which includes, by weight, 1-2 parts of fluoro-silicone copolymerized resin, and 98-99 parts of ethyl nonafluorobutyl ether. The coating is a novel super nano antifouling coating having better antifouling effect and being more economical. Through a special coating technology, a larger processing size is allowed. In addition, the coating can be applied on different inorganic materials, such as ceramic, metal AL, MG, SUS stainless steel, etc. The technology can replace a conventional PVD process.

Description

technical field [0001] The invention relates to the technical field of antifouling coatings, in particular to a coating with strong antifouling ability, which can be coated on various materials and shapes, and a coating method used in the field of 3C electronics. Background technique [0002] Traditional anti-fouling materials are prepared by washing-magnetic control (PVD) process. The disadvantage of this process is that the anti-fouling effect is not long-lasting, and it is easy to lose its anti-fouling effect under the influence of external forces such as hot water cooking, steel wool, and rubber wear. dirty effect. For example, in mobile phones, notebooks and other products that require relatively high anti-pollution appearance, consumers' living habits are prone to lipstick / hand cream / sunscreen oil / cola and other products are easy to touch the surface of the product, causing pollution to the appearance of the product and affecting users look and feel. In addition, in ...
