Description
Technical field
The invention belongs to protect technical field of membrane, and in particular, to a kind of optical grade 2.5D super abrasive screen protecting film.
Background technique
Screen protecting film is also known as mobile phone cosmetic membrane, safeguard film for cellular phone, is a kind of cold lamination film for mounting mobile phone screen.
The characteristics of PVC material protective film is texture softness itself, and is pasted conveniently, but this material is thicker, light transmission
It spends bad, screen is made to seem dimmer.Also the marking of glue can be left after tearing on the screen.This material also compares simultaneously
It is easier to the change with temperature and turns over yellow fuel-displaced, service life is shorter.So being substantially not visible this protective film on the market
?.
On the market can it is seen that a kind of PVC improvement version protective film, solve that previously thick and heavy and translucency is bad asks
Topic but still cannot solve the problems, such as to be easy to turn over yellow fuel-displaced, and should be noted this material of PVC and do not have anti-scratch
Ability, just will appear apparent scratch on protective film after a period of use, the display effect for influencing screen also influences hand
Other PVC of aesthetics of machine entirety itself is a kind of toxic material, contains heavy metal component, stops making comprehensively in Europe
It is sold in the market with the screen protecting film of this PVC improvement plate matter than wide, feature is hand held to feel very soft
Soft, many well-known protective film producers have also stopped using this material.
PET material protective film is current one of the most common type protector on the market, the entitled mylar .PET material of chemistry
The characteristics of protective film is that quality is harder, compares scratch resistance and use for a long time will not turn over yellow fuel-displaced as PVC material
But the protective film of general PET is easier to blister and fall off, even if but having fallen off in clear water by Electrostatic Absorption
In wash and may be reused .PET material protective film price ratio PVC it is expensive many.Many famous foreign brand mobile phones
When factory, what is configured at random is PET material protector, smart compared with packaging using PET material protector patch workmanship
Beauty has and carrys out tailor-made protector exclusively for hot buy mobile phone model, and not needing to cut can be used directly.
For screen protecting film, the current country is primarily present following patent document：
The Chinese patent of Publication No. CN107857951A discloses a kind of plastic film, and in particular to a kind of cell phone screen glass
