Abstract
The present invention relates to a kind of mobile phone shell and preparation method thereof, the mobile phone shell of the present invention is to add rubber in rubber solvent naphtha to add alkali grain after dissolving, inject mobile phone shell mould, rubber is carried out vulcanizing treatment, finally smear what acid reagent prepared at the mobile phone shell back side.The using method of the mobile phone shell of the present invention is that mobile phone shell is pressed in smooth object surface, air in mobile phone shell hole below can part be discharged, due to rubber with body surface laminating closely, air cannot flow freely into hole again, the air pressure in hole is caused to be less than external atmosphere pressure, so the atmospheric pressure in mobile phone front can by mobile phone shell pressure on a surface of an.The mobile phone shell that the present invention prepares is possible not only to function well as the effect of protection mobile phone, and can liberate both hands, has multifunctionality.
Description
Technical field
The invention belongs to rubber mobile phone shell field, be specifically related to a kind of mobile phone shell and preparation method thereof.
Background technology
From last century the nineties, cell-phone cover or mobile phone shell start the most prevailing by the opportunity that mobile phone is reduced weight,
Its kind is also with mobile phone brand and the increase of function in variation, and dividing by quality has leather, silica gel, cloth, duroplasts, soft
Plastics, knitting wool, the product such as silk are other, divide by type, the difference having straight plate with renovating.Limited by type, fitting of cell-phone cover
The most different by classification, bar phone generally can use the other cell-phone cover of universal class, and slide phone and clamshell phone the most often can only
Select leather sheath.
Phone housing develops into now, is the most no longer simple utility goods.Along with popularizing of mobile phone, almost each chases after
The user seeking fashion is intended to have a unique mobile phone, has gradually become them to show the one of individual character to mobile phone beauty treatment
The mode of kind.In order to cater to this trend, it is the most superior that mobile phone protective cover manufacturer is proposed again many workmanships, and colour image is more
Unique product, this makes the type more diversification of mobile phone protective cover.
In China, along with various middle and high ends mobile phone uses the generalization of crowd, universalness, it is seen that the development of whole world cell-phone cover
Prospect so that the manufacturer of cell-phone cover emerges as emerged rapidly in large numbersBamboo shoots after a spring rain.These companies with various manufacture of materials cell-phone covers,
The most also focusing on attractive in appearance, the individual character of cell-phone cover, and quality, the variation of cell-phone cover, diversification emerges in an endless stream.
On market, existing phone housing is many based on plastic material, is designed with all kinds of individualized pattern above, but is in addition to
Protective effect when mobile phone is fallen, almost without other more utilitarian functions.In daily life, people need in a lot of occasions
Mobile phone is fixed on a place to liberate both hands, when our rest in bed, it is desirable to mobile phone can be fixed on head board
Upper broadcasting video；When the one section of video that needs when staying alone to autodyne uploads to social networks, it is desirable to mobile phone can be just facing to oneself
Fix on the wall；Want to be directly anchored to mobile phone on vanity mirror directly play study course when making up；When shaving facing to mirror
Wish to mobile phone is fixed on mirror viewing ball match；Need mobile phone sticker building over there when needing and autodyning together with friend
Build on thing；Mobile phone need to be placed directly against record on equipment when body-building；Need when cooking to watch on mobile phone sticker cabinet simultaneously
Menu study course etc..
Summary of the invention
In order to realize this target, it is an object of the invention to provide a kind of mobile phone shell and preparation method thereof.
A kind of technical scheme of the present invention is: a kind of mobile phone shell, and the degree of depth extends to inner side equal to the thickness of mobile phone, edge
1～2 millimeter, by mobile phone parcel in order to avoid mobile phone abjection, when needs take out mobile phone, block an angular outside of mobile phone shell with finger
Moving, mobile phone can depart from mobile phone shell.
Further, mobile phone shell uses special rubber to make, and this material is interpolation alkali grain system in elastomeric material
Forming, the weight proportion of rubber and alkali grain is 80:20, and conventional alkali grain is calcium carbonate, magnesium oxide, zinc oxide
Deng.
Further, in the present invention, the manufacture method of special rubber has multiple, and its principle is first by rubber and alkalescence
Grain merges, and is fabricated to the shape needed, and after special rubber cools down, utilizes chemical solvent, with alkali grain, chemistry occurs
Reaction, by partial alkaline grain dissolution, i.e. there will be a lot of hole in special rubber, chemical solvent is usually glacial acetic acid or third
Acid, response time 8～10 minutes.
Further, alkali grain to accomplish macroscopic size, and particle diameter is 0.2～0.3mm, undersized
Words, the hole worked it out is less, and easily the dust in absorption air, causes the absorbability of mobile phone shell to weaken.
Further, the smooth surface that the inside of mobile phone shell contacts with mobile phone, without hole, at the back side of mobile phone shell, distribution
Hole after having various alkali grain to dissolve.
Further, the using method of the present invention is, after mobile phone is loaded mobile phone shell, when needs liberation both hands, by hands
Casing is attached to be had on the object of smooth surface.
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.

Detailed description of the invention
As Figure 1-4, a kind of mobile phone shell, the degree of depth extends 1～2 millimeter equal to the thickness of mobile phone, edge to inner side, will
Mobile phone parcel is in order to avoid mobile phone abjection, and when needs take out mobile phone, the angular outside blocking mobile phone shell with finger moves, and mobile phone is i.e.
Mobile phone shell can be departed from.
Further, the material of mobile phone shell uses special rubber, and this material is interpolation alkali grain in elastomeric material
Being made, the weight proportion of rubber and alkali grain is 80:20, and conventional alkali grain is calcium carbonate, magnesium oxide, zinc oxide
Deng.
Further, in the present invention, the manufacture method of special rubber has multiple, and its principle is first by rubber and alkalescence
Grain merges, and is fabricated to the shape needed, and after special rubber cools down, utilizes chemical solvent, with alkali grain, chemistry occurs
Reaction, by partial alkaline grain dissolution, i.e. there will be a lot of hole in special rubber.Chemical solvent is usually glacial acetic acid or third
Acid, response time 8～10 minutes.Air meeting portion when mobile phone shell is pressed in smooth object surface, in mobile phone shell hole below
Dividing and discharge, due to rubber with body surface laminating closely, air cannot flow freely into hole again, causes the air pressure in hole to be less than
External atmosphere pressure, so the atmospheric pressure in mobile phone front can by mobile phone shell pressure on a surface of an.
