Description
Technical field
The present invention relates to screen protector hardening information coating and its preparation method and application.
Background technology
Gradually stepping up with people's living standard, the electric touch screen equipment such as mobile phone, panel computer is increasingly popularized, and electricity
The resolution ratio more and more higher of sub- product, color is also distinct all the more true to nature, and screen size is larger, and thus brings a lot " face "
Problem, such as easily scraped drawn, mirror is anti-more apparent etc. has had a strong impact on the attractive in appearance of screen and used, the screen guarantor that it arises at the historic moment
Cuticula also emerges in an endless stream, and species is various, and quality is uneven.
At present, the screen protector on market mainly has PP material, PVC material and three kinds of PET material.The patch of PP material
Film is softer it is seen that light transmission rate is relatively low, and anti-scratch, anti-wear effect are poor, only dust protection, so substantially being consumed now
Person " forgets ".PVC material pad pasting is soft but easily pastes, but pad pasting itself is very thick, and therefore translucency is general, and
If tearing pad pasting, mobile phone screen then can leave cull it is difficult to process.The pad pasting of PET material has higher translucency, tears
After there is no cull, be also not easy to occur the minute bubbles in the middle of pad pasting；But, the hardness of this pad pasting is low, reflectance is high, can lead to
User does not see the word on screen, or even can injure eyes, and the illuminance of mobile phone screen itself has been just under normal circumstances
Very low, patch last layer pad pasting can increase the fatigue of eyes, also easily leave the vestiges such as fingerprint and oil stain from the teeth outwards simultaneously.Cause
How this, improve abrasion resistance, light transmittance, anti-glare and the uvioresistant performance of display screen, is that coatings art is in the urgent need to address
Technical problem.In addition, the counterfeit and shoddy goods on market are relatively more, harmful competition is unfavorable for the protection of product and opens further
Send out, it is necessary for increasing product self anti-counterfeiting function.
