Description
Technical field
This utility model relates to a kind of composite resin cover plate.
Background technology
Traditional touch screen touch screen (English touch panel, be called for short TP) cover plate all uses glass material, but should
There is natural defect in the TP cover plate planting glass material composition, as glass is broken, there is potential danger.In order to solve above-mentioned safety
Problem, when touch screen is prepared by most of touch screen manufacturers, pastes rupture pressure disc on the surface of glass cover-plate.But at TP cover plate
On paste rupture pressure disc and can produce some drawbacks equally, such as because having pasted rupture pressure disc, the case hardness of TP cover plate and surface abrasion resistance
Performance can decline, and after a certain period of use time, TP lid surface can be affected TP cover plate outward appearance by serious damage.And typically TP
Cover plate is all coated with functional film layer, and such as AG film (anti-dazzle), AR film (antireflective), if carrying out pasting rupture pressure disc at glass surface
After, TP lid surface will be caused to cannot be carried out antireflective (AR) or the process of anti-dazzle (AG), even if carry out antireflective (AR) or
The process of anti-dazzle (AG), also because having pasted rupture pressure disc, can cause the effect of antireflective and anti-dazzle directly to lose efficacy,
It is unable to reach satisfied touch experience.
The TP cover plate of simple PMMA composition, bending strength is not enough, easily causes deformation for touch screen, affects sense of touch；
The TP cover plate of simple PC composition, case hardness too low (only 2B), do not reach preferable hardness yet want even if sticking cured film
Ask.And above-mentioned simple PMMA plate or PC plate all cannot additional phase difference functions.Those problems are the most urgently to be resolved hurrily.
Utility model content
The technical problems to be solved in the utility model is to overcome the TP cover plate being made up of in prior art glass material
When surface pastes rupture pressure disc, TP lid surface hardness and surface abrasion resistance can decline, and after using a period of time, surface can be by sternly
Heavily scratch, affect outward appearance, and be unfavorable for that TP lid surface carries out antireflective or anti-dazzle processes, and simple PMMA plate bending resistance
Intensity is not enough, easily causes deformation for touch screen, affects sense of touch, and simple PC plate case hardness is too low, even if sticking
Cured film does not reaches the defect of desirable yet, it is provided that a kind of composite resin cover plate.Composite resin cover plate of the present utility model
Not only excellent in optical properties, and case hardness is high, bending strength high, angularity is less, impact resistance good, and safety is high,
Without pasting rupture pressure disc, the process of various surfaces can be carried out.Additionally, it becomes curved touch screen also by the pattern making of thermal flexure
Cover plate.
