Embodiment 1

[0052] The production process of the protective film includes:

[0053] First, make a release film.

[0054] The mixture of the matrix and the protruding particles is coated on the surface of the release base material layer by a dimple coating method, and a release layer is formed on the surface of the release base material layer, thereby forming a release film.

[0055] Next, the raw material of the adhesive layer is coated on the surface of the protective substrate layer to form an adhesive layer.

[0056] Finally, the release film is attached to the adhesive layer on the surface of the protective substrate layer and cured under constant humidity conditions at 50°C to form a protective film, forming a protective substrate layer, an adhesive layer, and a release layer in order from bottom to top. The release substrate layer, wherein the structure of the release film is as figure 1 shown.

[0057] Among them, the protective substrate layer and the release substrate layer ar...

Embodiment 2

[0059] The difference with Example 1 is that the structure of the formed release film is as image 3 As shown, the protruding particles are PU particles with a particle size between 10 and 13 μm.

Embodiment 3

[0061] The difference from Example 2 is that the particle size of the PU particles is between 5-8 μm.

Abstract

The invention provides a release film, a protective film and a display device. The release film comprises a release substrate layer and a release layer, wherein the release layer is arranged on the surface of the release substrate layer, one release layer surface far from the release substrate layer is provided with a plurality of extruding particles, which extrude from one surface of the release layer. The surface of the release layer has extruding particles, and when the release film is applied in the protection film, the extruding particles can cause gaps between the release layer and an adhesive layer, the gaps can be convenient for hot air flow, thus shortening the curing time of the adhesive layer, curing the adhesive layer rapidly, and avoiding the problem of adhesive residue. Also, the performance of the protective film can be more stable.

Description

technical field [0001] The present application relates to the field of materials, in particular, to a release film, a protective film and a display device. Background technique [0002] The protective film in the prior art generally includes a substrate and an adhesive layer arranged on the surface of the substrate. Generally, the adhesive layer can be an acrylic coating, a silica gel coating or a polyurethane coating (also known as a PU coating), wherein the silica gel coating The breathability of the layer is better. [0003] However, the above-mentioned protective film products in the prior art need to be matured for a long time after the production is completed, which not only causes waste in cost, but also causes unstable performance of the protective film and even residual glue phenomenon due to the insufficient ripening of the adhesive layer. . Contents of the invention [0004] The main purpose of the present application is to provide a release film, a protective...
