Abstract
The present invention relates to a kind of mobile phone shells and preparation method thereof, mobile phone shell of the invention is rubber to be added in rubber solvent naphtha to add alkali grain after dissolution, mobile phone shell mold is injected, vulcanizing treatment is carried out to rubber, is finally smeared made from acid reagent at the mobile phone shell back side.The application method of mobile phone shell of the invention is that mobile phone shell is pressed in smooth object surface, air in the subsequent hole of mobile phone shell can partially be discharged, since rubber is bonded closely with body surface, air can not flow freely into hole again, the air pressure in hole is caused to be less than external atmosphere pressure, so the atmospheric pressure of mobile phone front can be by mobile phone shell pressure on a surface of an.Mobile phone shell produced by the present invention can not only function well as the effect of protection mobile phone, but also can liberate both hands, have multifunctionality.
Description
Technical field
The invention belongs to rubber mobile phone shell fields, and in particular to a kind of mobile phone shell and preparation method thereof.
Background technique
From last century the nineties, cell-phone cover or mobile phone shell start by the opportunity that mobile phone is reduced weight it is gradually prevailing,
Its type also with mobile phone brand and function increase and in diversification, point have leather by quality, silica gel, cloth, duroplasts is soft
Plastics, knitting wool, the product such as silk are other, and then have the difference of straight panel and flip lid by type point.It is limited by type, cell-phone cover is fitted
Also different with classification, bar phone can usually use the other cell-phone cover of universal class, and slide phone and clamshell phone then often can only
Select leather sheath.
Phone housing is no longer simple utility goods till now.With popularizing for mobile phone, almost each is chased after
It asks the user of fashion to be intended to possess a unique mobile phone, gradually shows the one of individual character at them to mobile phone beauty
Kind mode.In order to cater to this trend, mobile phone protective cover manufacturer is proposed that many workmanships are more superior, and colour image is more again
Unique product, this makes the type more diversification of mobile phone protective cover.
Generalization, universalness in China, with various middle and high end mobile phones using crowd, it is seen that the development of global cell-phone cover
Prospect, so that the manufacturer of cell-phone cover emerges as emerging rapidly in large numbersBamboo shoots after a spring rain.These companies produce cell-phone cover with a variety of materials,
Also focus on beauty, individual character and the quality of cell-phone cover, the diversification of cell-phone cover simultaneously, diversification emerges one after another.
For existing phone housing mostly based on plastic material, design has all kinds of individualized patterns above in the market, but in addition to
Protective effect when mobile phone is fallen, almost without other more utility functions.In daily life, people need in many occasions
Mobile phone is fixed on a place to liberate both hands, when our rests in bed, it is desirable to which mobile phone is capable of fixing in headpiece
Upper broadcasting video；When one section of video of self-timer being needed to upload to social networks when staying alone, it is desirable to which mobile phone can be just facing to oneself
It fixes on the wall；Want to be directly anchored to mobile phone directly to play study course on vanity mirror when makeup；When shaving against mirror
It wishes to for mobile phone being fixed on mirror and watches ball match；When needing and when friend's self-timer together needs mobile phone sticker building over there
It builds on object；Mobile phone need to be placed directly against on equipment and be recorded when body-building；It needs on mobile phone sticker cabinet while to watch when cooking
Menu study course etc..
Summary of the invention
In order to achieve this goal, the purpose of the present invention is to provide a kind of mobile phone shells and preparation method thereof.
A kind of technical solution of the invention is: a kind of mobile phone shell, and depth is equal to the thickness of mobile phone, and edge extends inwardly
1~2 millimeter, by mobile phone package in order to avoid mobile phone is deviate from, when needing to take out mobile phone, an angular outside of mobile phone shell is blocked with finger
It moves, mobile phone can be detached from mobile phone shell.
Further, mobile phone shell is made of special rubber, and this material is the addition alkali grain system in rubber material
It forms, the weight proportion of rubber and alkali grain is 80:20, and common alkali grain is calcium carbonate, magnesia, zinc oxide
Deng.
Further, in the present invention there are many production methods of special rubber, principle is first by rubber and alkalinity
Grain is fused together, and is fabricated to the shape of needs, and after special rubber is cooling, chemistry occurs using chemical solvent and alkali grain
Partial alkaline grain dissolution will appear many holes in special rubber, chemical solvent is usually glacial acetic acid or third by reaction
Acid, the reaction time 8~10 minutes.
Further, alkali grain will accomplish macroscopic size, and particle diameter is 0.2~0.3mm, undersized
Words, the hole worked it out is smaller, and the dust being easy in absorption air causes the adsorption capacity of mobile phone shell to weaken.
Further, the surface that the inside of mobile phone shell is contacted with mobile phone is smooth, no hole, at the back side of mobile phone shell, distribution
There is the dissolved hole of various alkali grains.
Further, application method of the invention is, after mobile phone is packed into mobile phone shell, when needing to liberate both hands, by hand
Casing is attached on the object with smooth surface.
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.

Specific embodiment
As shown in Figs 1-4, a kind of mobile phone shell, depth are equal to the thickness of mobile phone, and edge extends 1~2 millimeter inwardly, will
Mobile phone package, when needing to take out mobile phone, is moved, mobile phone is in order to avoid mobile phone is deviate from the angular outside that finger blocks mobile phone shell
Mobile phone shell can be detached from.
Further, the material of mobile phone shell uses special rubber, and this material is that alkali grain is added in rubber material
It is made, the weight proportion of rubber and alkali grain is 80:20, and common alkali grain is calcium carbonate, magnesia, zinc oxide
Deng.
Further, in the present invention there are many production methods of special rubber, principle is first by rubber and alkalinity
Grain is fused together, and is fabricated to the shape of needs, and after special rubber is cooling, chemistry occurs using chemical solvent and alkali grain
Partial alkaline grain dissolution will appear many holes by reaction in special rubber.Chemical solvent is usually glacial acetic acid or third
Acid, the reaction time 8~10 minutes.Air meeting portion when mobile phone shell is pressed in smooth object surface, in the subsequent hole of mobile phone shell
Divide discharge, since rubber is bonded closely with body surface, air can not flow freely into hole again, and the air pressure in hole is caused to be less than
External atmosphere pressure, so the atmospheric pressure of mobile phone front can be by mobile phone shell pressure on a surface of an.
