Abstract
The invention provides an anti-blue-light and anti-static protective film. The anti-blue-light and anti-static protective film comprises a transparent base material and an anti-blue-light coating arranged on the surface of the transparent base material. Black dye and an anti-static agent are contained in the anti-blue-light coating. According to the anti-blue-light and anti-static protective film, due to the fact that the anti-static agent is added, the internal tension and the leveling characteristic of the anti-blue-light coating can be improved, and the anti-blue-light and anti-static protective film has a good anti-blue-light effect and a good anti-static effect at the same time. In addition, the anti-blue-light component in the protective film is the black dye, the black dye can lower the transmittance of the protective film, and thus the absorption to blue light by the protective film is reduced. Compared with the prior art, the yellowness value of the anti-blue-light and anti-static protective film is too low, and the influence of color deviation cannot be brought to users. Moreover, the anti-blue-light and anti-static protective film further has good hardness, attrition resistance, adhesive force, transmittance and hazes.

According to the method described in technique scheme, test the hardness of the antistatic protection film that comparative example 3 of the present invention prepares, wear-resisting consumption, static value, sticking power, b
*the transmitance of the transmitance of value, mist degree, total light transmittance, 400nm wavelength, the transmitance of 430nm wavelength and 450nm wavelength; Test result is as shown in table 1.
The performance test results of the protective membrane that table 1 embodiment of the present invention and comparative example provide
As shown in Table 1, the embodiment of the present invention adopts black dyes and static inhibitor to regulate transmitance and the antistatic effect of anti-blue light coating; The present invention adopts black dyes to prepare anti-blue light and antistatic protection film, the b* value of described protective membrane is suitable for, without partially yellow situation, but also the anti-blue light effect of anti-blue light provided by the invention and antistatic protection film and antistatic effect are compared with antistatic protection film with anti-blue light protective membrane simple in comparative example, the better effects if of its anti-blue light and anti-electrostatic, therefore, the anti-blue light that provides of comparative example of the present invention and antistatic protection film have the effect of good anti-blue light and anti-electrostatic simultaneously; In addition, anti-blue light provided by the invention and antistatic protection film also have good hardness, wear resistant, sticking power, transmitance and mist degree.
As seen from the above embodiment, the invention provides a kind of anti-blue light and antistatic protection film, comprising: transparent substrate; Be arranged on the anti-blue light coating of described transparent substrate surface, containing black dyes and static inhibitor in described anti-blue light coating.In the present invention, static inhibitor add the inner tensions and levelling characteristic that can improve anti-blue light coating, make anti-blue light provided by the invention and antistatic protection film have good anti-blue light effect and anti-static effect simultaneously.In addition, in protective membrane provided by the invention, anti-blue light ingredient is black dyes, and described black dyes can reduce the blue light transmitance of protective membrane, thus improves protective membrane to the absorption of blue light.Compared with prior art, the yellow value degree of anti-blue light provided by the invention and antistatic protection film is on the low side, can not bring the impact of color error ratio to user.In addition, anti-blue light provided by the invention and antistatic protection film also have good hardness, wear resistant, sticking power, transmitance and mist degree.
