Problems solved by technology

The addition of matting powder not only increases the cost, but most of the traditional matting powders use solvents, and then add powder materials for matting. In recent years, due to the rising awareness of environmental protection and the formulation of relevant laws and regulations, traditional matting powders do not meet the requirements of environmental protection in current regulations. In addition, the traditional matte film needs to strictly control the viscosity of the paint and the particle size of the matting powder; due to the insolubility of the matting powder, it is easy to precipitate in the paint, resulting in uneven matteness of the matte writing film produced

Embodiment 1

[0033] (1) Coating a layer of light-cured writing material on the surface of the PET substrate layer;

[0034] (2) passing the PET substrate layer containing the photocurable writing material through a photocuring mechanism, and the photocuring mechanism irradiates the photocurable writing material to make it solidify and press-fit to obtain a matte writing film;

[0035]The photocuring mechanism includes a roller, a first fastening roller and a first curing light source device, the first curing light source device is located above the roller, and the PET substrate layer containing the photocurable writing material is located between the roller and the first fastening roller In between, the outer surface of the roller is concave with a number of concave parts, the concave parts have an arc structure, and the distance from the bottom of the concave part to the outer surface of the roller wheel is 0.01um.

[0036] Wherein, the photocurable writing material, in parts by weight, i...

Embodiment 2

[0038] The preparation method of the matte writing film in this embodiment is basically the same as that in Embodiment 1, except that the distance from the bottom of the concave portion to the outer surface of the roller in this embodiment is 0.05um.

Embodiment 3

[0040] The preparation method of the matte writing film of this embodiment is basically the same as that of Embodiment 1, except that in this embodiment, the distance from the bottom of the concave portion to the outer surface of the roller is 0.1 um.

Abstract

The invention provides a preparation method of a matte writing film. The preparation method comprises the following steps: (1) the surface of a polyethylene terephthalate (PET) substrate layer is coated with a layer of photo-curing writing material; and (2) the PET substrate layer containing the photo-curing writing material passes through a photo-curing mechanism, and the light curing mechanism is used for carrying out light irradiation on the photo-curing writing material so as to cure and press the photo-curing writing material, so that the matte writing film is obtained. The photo-curing mechanism comprises a roller wheel, a first fastening roller and a first curing light source device; the PET substrate layer containing the photo-curing writing material is located between the roller wheel and the first fastening roller; a plurality of concave parts are concavely arranged in the outer surface of the roller wheel; and the concave parts are of arc structures, wherein the distance from the bottom of each concave part to the outer surface of the roller wheel is 0.01-0.2 microns. According to the method, preparation cost of the matte writing film is reduced, the environment is protected at the same time, and the film surface of the matte writing film has uniform glossiness, is easy to wipe, is long in service life and is stable in storage.

Description

technical field [0001] The invention relates to the technical field of matte writing films, and more particularly to a preparation method of a matte writing film. Background technique [0002] In recent years, people's living standards have gradually improved, and they have gradually felt that the high-gloss high-gloss writing film has serious reflections, which greatly damages the visual ability. Therefore, the matte writing film is widely used in graffiti or teaching, and the production of the matte writing film is usually by adding a matte powder to the resin coating to display the matte effect. Adding matting powder not only increases the cost, but most traditional matting powders use solvents, and then add powdery materials for matting. In recent years, due to the rising awareness of environmental protection and the formulation of relevant regulations, traditional matting powders do not meet the current regulations. The requirements of environmental protection In addit...
