Embodiment 1

[0026] Embodiment 1 borosilicate resin

[0027] The borosilicate resin of the present invention is independently designed and synthesized. It is composed of silane coupling agent KH570, borosiloxane resin and tetraphenyldimethyldisilane. The degree of polymerization is 2-50, and each chain link contains 3 Acrylate and 2 boron molecules, the general reaction formula is:

[0028]

Embodiment 2

[0030] The preparation of the high-transmission and high-fog anti-glare film of this embodiment is carried out as follows: take B-MDT45wt%, photocurable resin 45wt%, photoinitiator and auxiliary agent 10wt%, B-MDT, photocurable resin, photoinitiator and Mix organic solvents, disperse at a high speed for 15 minutes, and disperse at a speed of 1000-2000rpm, then add additives, and continue to disperse at a high speed for 15 minutes to obtain a coating liquid; apply the coating liquid to optical surfaces by dimple coating or blade coating On the surface of PET film, the coating thickness is 1-20 microns, dried at 80-100°C for 5-10 minutes, and then enters the UV exposure machine for radiation curing, and the radiation dose is 400-2000mJ / cm 2 , the coating speed is 5-20 m / min, and a high-transparency, high-fog, anti-glare film is obtained.

[0031] Wherein, B-MDT is obtained by the method of Example 1; the photocurable resin is aliphatic polyurethane hexaacrylate resin, Sartomer, ...

Embodiment 3

[0034] The preparation of the high transparency and high fog anti-glare film of this example is carried out as follows: Take 20wt% of B-MDT, 20wt% of photocurable resin, 50wt% of reactive diluent, 10wt% of photoinitiator and auxiliary agent, and mix B-MDT, photocuring Mix resin, reactive diluent, photoinitiator and organic solvent, disperse at a high speed for 15 minutes at a speed of 1000-2000rpm, then add additives, continue to disperse at a high speed for 15 minutes, and obtain a coating solution; use dimple coating or blade coating Apply the coating solution on the surface of the optical PET film by cloth method, the coating thickness is 1-20 microns, dry at 80-100°C for 5-10 minutes, enter the UV exposure machine for radiation curing, and the radiation dose is 400-2000mJ / cm 2 , the coating speed is 5-20 m / min, and a high-transparency, high-fog, anti-glare film is obtained.

[0035] Wherein, B-MDT is obtained by the method of Example 1; the photocurable resin is aliphatic ...

Abstract

The invention discloses a high-transparency and high-fog anti-glare coating, which comprises a UV-curable borosilicate resin (B-MDT), a UV-curable acrylic resin, a reactive diluent, a photoinitiator and an auxiliary agent, according to weight percentage It is: 10-70% of boron-containing silicone resin, 10-50% of acrylic resin, 10-70% of reactive diluent, 1-5% of photoinitiator, and 5-9% of auxiliary agent. On the basis of ensuring that the product has an anti-glare effect, the coating of the present invention ensures high light transmittance and high haze, and the light transmittance when coated on the film can reach more than 90%, and the haze is 60% to 85%. It is difficult to achieve a haze of more than 75% when the light transmittance of the film is kept above 90%.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and relates to a coating with high light transmittance, high haze and anti-glare. Background technique [0002] Glare refers to the inappropriate range of light brightness in the field of vision, and there is an extreme light brightness contrast in space or time, which causes discomfort or reduces visibility. To a certain extent, glare will directly affect the labor efficiency of workers and Human vision is healthy, and it can cause eye diseases and other problems in severe cases. Therefore, it is of great significance to take effective measures to prevent and control glare to improve people's visual health and quality of life. [0003] Anti-glare can be achieved by controlling the light source, or it can be controlled during the transmission of light, and the specular reflection of light can be changed into diffuse reflection through the anti-glare film, which can effectively reduce th...
