Technical Field

The invention relates to the field of production and processing of mobile phone shells, in particular to a pretreatment method for a coating film of a mobile phone shell.

Background

The coating is such that approximately 5% of the light is reflected when it enters different transmission substances (e.g. air into the glass), and the total loss of the incident light is 30-40% due to the presence of many lenses and refractors in the optical sighting telescope. Modern optical lenses are usually coated with a single layer or multiple layers of magnesium fluoride antireflection film, the single layer antireflection film can reduce the reflection to 1.5%, and the multiple layers of antireflection film can reduce the reflection to 0.25%, so that the light transmittance of the whole telescope can reach 95% if the whole telescope is properly coated. Lenses coated with a single layer of antireflective film are typically bluish purple or red, while lenses coated with multiple layers of antireflective films are greenish or dark purple.

However, the mode of pretreating the mobile phone shell before the coating treatment of the mobile phone shell in the market is not perfect at present, so that the situation that the coating of the mobile phone shell is not uniform is easy to occur after the coating of the mobile phone shell, scratches are easily generated at the thin part of the coating in the using process of the mobile phone shell, and the thin part of the coating is more easily deformed in collision.
