Description
Technical field
The invention belongs to leather sheath technical field, particularly relate to that a kind of high transparency is silica gel protected applies mechanically double-component silica gel.
Background technology
Along with popularizing of mobile phone, Leather cover for handset is also favored by people.Especially young cluster, following the fashion, individual character
Changing, the style to Leather cover for handset, quality, function etc. requires more and more.The most common Leather cover for handset function has shatter-resistant, anti-
Sliding, antitheft, dormancy, the function such as attractive in appearance.Additionally mobile phone protective cover can effectively prevent hard thing from causing mobile phone screen or fuselage
Cut, it is also possible to avoid mobile phone to fall the problems such as even breakage of colliding with caused.It is currently used in the middle of the material of mobile phone protective cover, bag
Include numerous plastic material such as silica gel and leather sheath.But silica gel sheath is saturating
Gas is poor, and long periods of wear will cause handset accumulated heat, is not particularly suitable for the smart mobile phone that caloric value is higher.And
Silica gel sheath itself has slight viscosity, uses a period of time post-concentration collection a large amount of dusts of absorption on mobile phone, is unfavorable on the contrary
Mobile phone attractive in appearance, runs in the opposite direction with the original intention of protection mobile phone.
Mobile phone protective cover the most on the market has multiple material, has silica gel, polyurethane material.And these protection set materials are such as
Fruit is accomplished fully transparent, and intensity will significantly decline, and can not meet the requirement of strength of mobile phone protective cover, so the most on the market
Silicone Case all with color, it is impossible to accomplish transparent.The most transparent cell-phone cover of main flow is polyurethane material
Material, but it exists the shortcoming of easy xanthochromia, substantially in one month will obvious xanthochromia, have a strong impact on the outward appearance of mobile phone, and
This characteristic is to be determined by the characteristic of polyurethane itself, is difficult to be overcome, and therefore, needs one badly and has intensity and high transparency and not concurrently
Can the Novel electronic product protection set material of xanthochromia, it is i.e. a kind of that high transparency is silica gel protected applies mechanically double-component silica gel.
Summary of the invention
It is an object of the invention to provide that a kind of high transparency is silica gel protected applies mechanically double-component silica gel, the intensity of this silica gel and thoroughly
Lightness is all adapted to the use requirement of existing market, and xanthochromia will not occur, thus efficiently solves in above-mentioned prior art
The problem existed.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of high transparency is silica gel protected applies mechanically double-component silica gel, and its constituent is counted as follows by weight:
The polydimethylsiloxane 40 70% of ethenyl blocking
Vinyl polysiloxane 20 50%
Additive 1 20%.
Preferably, its constituent is counted as follows by weight:
The polydimethylsiloxane 65% of ethenyl blocking
Vinyl polysiloxane 30 35%
Additive 1 5%.
Preferably, described additive is the platinum catalyst of 0.1-100PPM.
Preferably, described additive is the platinum catalyst of 20PPM.
Preferably, described additive includes at least containing 3 SI-H keys in molecule polysiloxanes and 10-10000PPM's
Inhibitor.
Preferably, described inhibitor is ethynylcyclohexanol.
Preferably, described additive includes the hydrogen containing siloxane of 0.75% hydrogen content and the ethynylcyclohexanol of 600PPM.
Preferably, the polydimethylsiloxane of described ethenyl blocking be viscosity be the ethylene of 10000-200000mpa.s
Base terminated polysiloxane.
Preferably, described vinyl polysiloxane be molecular weight between 2000-10000, contents of ethylene is between 0.5-
Silicones between 5.5%.
Preferably, described vinyl polysiloxane be contents of ethylene be the silicones between 3%.
Compared to prior art, the beneficial effects of the present invention is: the silica gel in the present invention is by using transparent reinforcement
Filler solves the strength problem of transparent silica gel, can reach to meet the requirement of mobile phone protective cover intensity；And by reasonably joining
Side's design can avoid protection set in use to there is the risk of xanthochromia the same with polyurethane.
