Abstract

The invention discloses an earphone shell surface treatment method. The earphone shell surface treatment method comprises the following steps that a, the surface of a plastic shell is polished; b, after polishing, the plastic shell is sprayed with first paint, wherein silica particles, polyethylene glycol and oil paint in the first paint are mixed according to the weight ratio of 2-5:16-25:95-110,the particle size of the silica particles is 8-15 mu, and after spraying, drying is conducted on the first paint at the temperature of 65-75 DEG C for 20-30 min; c, the plastic shell is then sprayedwith second paint, metal particles and oil paint in the second paint are mixed according to the weight ratio of 3-8:100-110, the particle size of the metal particles is 18-25 mu, and after spraying, drying is conducted on the second paint at the temperature of 65-75 for 20-30 min; d, the second paint is sprayed with a UV protective layer, the UV protective layer is dried, and then the treated earphone shell is obtained. The earphone shell surface treatment method has the beneficial effects that the obtained earphone shell is good in texture, communication performance and anti-static performance.

Description

technical field [0001] The invention relates to a material for an earphone shell, in particular to a surface treatment method for an earphone shell. Background technique [0002] With the development of science and technology, in order to meet people's increasing consumer demand, manufacturers have developed a variety of wireless connection products, such as earphones, etc. The earphones are connected wirelessly with other terminals, so that the user is more convenient to use. At present, plastic shells are often used for earphone shells, but the plastic shells lack texture, are not beautiful enough, and are prone to static electricity, which can damage parts; if metal materials are used, not only the cost is high, but also signal interference will seriously affect the communication function. Contents of the invention [0003] The object of the present invention is to provide a surface treatment method for an earphone shell. The invention has the characteristics of good t...
