Problems solved by technology

[0002] With the continuous progress of human society, especially the rapid development of modern technology, people's life is inseparable from all kinds of electronic products, especially mobile phones, ranging from the elderly in their 70s and 80s, down to a few years old. There are no children who know how to use mobile phones, especially young people, who hold mobile phones in their hands and use them almost all the time. Mobile phones are different from human beings. They can make calls, listen to songs or play games, etc. The functions can be said to be very powerful. However, no matter how powerful a mobile phone or other electronic product is, once it encounters water, it may be dismantled for maintenance, or the entire device may be scrapped. In addition to property losses, important documents will also be lost

Abstract

The invention provides a waterproof mobile phone shell and a preparation method thereof. The waterproof mobile phone shell comprises a shell body. The shell body comprises an upper front shell, a sideshell, a lower front shell, a top shell, a bottom shell, a back shell and a waterproof coating coating the surface and the gap of the shell body. The prepared waterproof coating is prepared from perfluor alkane organic matter, a perfluor alkane solvent, sodium hydroxide or potassium hydroxide and water solution, halohydrocarbon, KARSTEDT catalyst and trimethoxy silane. The water contact angle ofthe obtained waterproof mobile phone shell is larger than or equal to 110 degrees, and the mobile phone shell has the good waterproof performance, oil resistance, wear resistance and acid and alkali resistance. After a mobile phone matched with the mobile phone shell is covered with the mobile phone shell, due to a waterproof experiment, the watertightness is 3 MPa, and no leakage is caused for 3h.

Description

technical field [0001] The invention relates to the technical field of waterproof shells for electronic devices, in particular to a waterproof mobile phone shell and a preparation method thereof. Background technique [0002] With the continuous progress of human society, especially the rapid development of modern technology, people's life is inseparable from all kinds of electronic products, especially mobile phones, ranging from the elderly in their 70s and 80s, down to a few years old. There are no children who know how to use mobile phones, especially young people, who hold mobile phones in their hands and use them almost all the time. Mobile phones are different from human beings. They can make calls, listen to songs or play games, etc. The functions can be said to be very powerful. However, no matter how powerful a mobile phone or other electronic product is, once it encounters water, it may be dismantled and repaired, or the entire device may be scrapped. In addition ...
