Problems solved by technology

[0002] With the rapid development of the mobile phone industry in recent years, smart phones have more and more functions, and most of the screens of the products use touch screens. For the newly purchased mobile phones, most people will choose to buy a mobile phone protective case to prevent the mobile phone from being scratched and dropped. Bad, but now people use mobile phones more and more frequently, the mobile phone will appear hot, and the heat dissipation performance of the mobile phone with the mobile phone case is even worse, which will reduce the life of the internal parts of the mobile phone over time; and the existing mobile phone case Generally, the exterior decoration is relatively simple, which does not meet the preferences of young consumers, and the outer surface of the mobile phone case is not painted, the style is relatively rough, and the surface of the protective case is easy to scratch and fade

Embodiment 1

[0033] Embodiment one: a method for spraying the surface of a mobile phone protective case, comprising the following steps in turn:

[0034] Step 1: Eliminate static electricity on the surface of the product: Take the ion wind rod and move it back and forth at a uniform speed on the surface of the mobile phone protective case to remove static electricity. Charge, when the charge on the surface of the mobile phone protective case is negative, the positive charge in the airflow is absorbed by the ion wind rod, and when the charge on the surface of the mobile phone protective case is positive, the negative charge in the airflow is absorbed by the ion wind rod, In this way, the static electricity on the surface of the mobile phone protective case is neutralized to achieve the purpose of eliminating static electricity;

[0035] Step 2: Product preheating: place the mobile phone protective case in the heating furnace for preheating. The initial preheating temperature is 65-75°C. Whe...

Embodiment 2

[0057] The second embodiment is roughly the same as the first embodiment, except that the A component is composed of the following components and the mass percentage of each component is:

[0058]

[0059]

[0060] After readjusting the proportions of the components in the second embodiment, 65% hydroxy acrylic resin is used, which can save costs, but the heat dissipation effect and discoloration effect of the protective case of the mobile phone are still similar.

Embodiment 3

[0062] The third embodiment is roughly the same as the first embodiment, except that the A component is composed of the following components and the mass percentage of each component is:

[0063]

[0064] After the proportions of the components in Example 3 are re-adjusted, the use of 15% xylene can make the components more fully mixed with each other and make the coloring of the spray paint more stable.

Abstract

The invention mainly discloses a method for spraying the surface of a mobile phone protective case, and its technical scheme: sequentially includes removing static electricity on the surface of the mobile phone protective case, preheating the surface of the mobile phone protective case, and using spray paint to spray a primer on the surface of the mobile phone protective case to form a sensory effect. Temperature-changing layer, the first high-pressure flushing, the first drying, spray paint on the surface of the mobile phone protective case to form a heat dissipation layer, the second high-pressure flushing, the second drying, and UV coating The surface of the mobile phone protective case is sprayed with surface paint to form a wear-resistant and scratch-resistant heat dissipation layer, which is cured and dried by UV furnace. The heat dissipation performance of the mobile phone protective case can be improved, and the wear-resistant and scratch-resistant heat dissipation layer can make the mobile phone protective case have a longer life, can make the spray paint stable, and the appearance of the protective case is more wear-resistant.

Description

technical field [0001] The invention relates to the technical field of spray paint, in particular to a method for spraying the surface of a mobile phone protective case. Background technique [0002] With the rapid development of the mobile phone industry in recent years, smart phones have more and more functions, and most of the screens of the products use touch screens. For the newly purchased mobile phones, most people will choose to buy mobile phone protective cases to prevent the mobile phone from being scratched and dropped. Bad, but now people use mobile phones more and more frequently, the mobile phone will appear hot, and the heat dissipation performance of the mobile phone with the mobile phone case is even worse, which will reduce the life of the internal parts of the mobile phone over time; and the existing mobile phone case Generally, the exterior decoration is relatively simple, which does not meet the preferences of young consumers, and the outer surface of th...
