Abstract

The invention relates to the technical field of optical films, specifically to a matte film and a preparation method thereof, and a haze adjustment method. The matte film successively comprises a non-matte layer, a matte layer and a substrate layer from top to bottom, wherein the matte layer comprises resin and organic particles. The preparation method comprises the following steps: coating mixedresin and the organic particles onto the surface of the substrate layer, carrying out curing so as to form the matte layer; and pressing a UV resin mold onto the surface of the matte layer, and carrying out curing to form the non-matte layer so as to obtain the matte film. The matte film provided by the invention has the following advantages: through arrangement of the matte layer and the non-matte layer, the organic particles of the matte layer can adjust the haze of the matte layer, and the non-matte layer is arranged on the matte layer, so the surface roughness of the finished matte film can be effectively adjusted; and through mutual adjustment and matching of the refractive indexes of the matte layer and the non-matte layer, the haze of the finished matte film can be further adjusted,so the matte film with a haze of 20% to 85% and a surface roughness of 0.1 to 0.15 can be obtained.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to a fog film, a preparation method thereof, and a haze adjustment method. Background technique [0002] With the development of display technology, in order to meet the actual needs, researchers have developed various optical films. As a kind of optical film, the fog film can adjust the light transmittance according to the actual product demand. [0003] In the prior art, the production method of the fog film is to add particles to the resin to obtain the required haze. When a higher haze is required, a large amount of added particles will affect the surface roughness of the finished product. As the amount of particles added increases, the roughness of the finished product surface increases sharply. [0004] However, when the surface roughness of the finished product is too high, the bonding force with the surface of the object to be pasted becomes poor, the adhesion is red...
