Problems solved by technology

The addition of frosted particles not only affects the adhesion between the glue and the substrate layer, but also causes bright spots when the light passes through the frosted particles, which affects vision
Moreover, due to the uneven distribution of frosted particles during the coating process, the protective film appears white and has uneven haze.

Abstract

The invention relates to the technical field of protective films, in particular to a frosted anti-dazzle protective film and a preparation method thereof. The frosted anti-dazzle protective film comprises a protective film layer, a frosted anti-dazzle coating layer, a base material layer, a bonding layer and a strippable film layer which are arranged in sequence from top to bottom, wherein the upper and lower surfaces of the frosted anti-dazzle coating layer are respectively adhered to the lower surface of the protective film layer and the upper surface of the base material layer; the upper and lower surfaces of the bonding layer are respectively adhered to the lower surface of the base material layer and the upper surface of the strippable film layer; the raw material of the frosted anti-dazzle coating layer adopts a mixture of a heat curing acrylic resin hardening liquid and a light curing acrylic resin hardening liquid with the ratio of the heat curing acrylic resin hardening liquid to the light curing acrylic resin hardening liquid being 1:(1-5). The frosted anti-dazzle protective film has a frosted effect and a good anti-dazzle effect, cannot produce problems of bright specks and turning white, can further improve light transmittance, guarantee the fidelity of images, and enhance the user experience.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a frosted anti-glare protective film and a preparation method thereof. Background technique [0002] With the development of optical protective films, more and more protective film functions have been developed. Among them, the effect of anti-glare frosting effect has been gradually paid attention to as one of the important properties. The matte effect will not cause the screen to be difficult to see due to reflections under strong light, and it also has a comfortable feel, which is more and more popular among mobile phone users. [0003] The frosted protective film in the prior art is realized by adding organic or inorganic frosted particles into the hardening solution. The addition of frosted particles not only affects the adhesion between the glue and the substrate layer, but also causes bright spots when the light passes through the frosted particles, which affects...
