Embodiment 1
[0032] Example 1: Matte release paper
[0033] See attached figure 1 As shown, a matte release paper is composed of six layers of coating layer 1, release paper base paper layer 2, adhesive layer 3, film layer 4, matte coating 5 and release agent coating 6 in sequence, The surface roughness of the surface of the matte coating 5 facing the release agent coating 6 is 2.821um-3.324um. Test standard: ISO4287:1998. Roughness tester: TR200 hand-held roughness tester produced by Beijing Times Peak Technology Co., Ltd. The matte coating 5 is a polyester matte coating. First, one side of the release paper base paper layer 2 (ordinary paper) is coated with the first coating layer 1 made of PE, and the other side is coated with a layer of adhesive layer 3, and then a layer of film layer is pasted on the adhesive layer 3 4. Then, the polyester matte coating 5 (made of polyester) is coated on the surface of the film layer 4. After the treatment, the surface has some uniform concave-con...
Embodiment 2
[0034] Embodiment two, the preparation method of matte release paper
[0035] See attached figure 1 Shown, a kind of preparation method of matte release paper, the preparation steps are as follows:
[0036] Step 1: First, treat the surface of the base paper of the release paper so that there is no paper scraps or stains on the surface.
[0037] Step 2: On the surface of one side of the base paper of the release paper, use a laminating machine to coat a layer of PE coating layer 1, and then cool it; Type A tape casting compound unit.
[0038] The third step: coating a layer of adhesive layer 3 on the surface of the other side of the base paper of the release paper;
[0039] The fourth step: attaching a polyethylene terephthalate film layer 4 to the surface of the adhesive layer 3;
[0040] Step 5: Coating a layer of matte coating agent with a thickness of 0.2 to 2 microns on the surface of the film layer 4 . The formula of the matte coating agent is shown in Table 1.

[0043] Embodiments three to six: a kind of preparation method of matte release paper
[0044] 1, method is the same as embodiment two.
[0045] 2, the related materials that embodiment three~six uses are as follows:
[0046] (1) Material of coating layer: Example 3, polyvinyl chloride; Example 4, polyethylene terephthalate; Example 5, polyethylene; Example 6, polypropylene.
[0047] (2) Film layer: Example 3, polypropylene film; Example 4, polyethylene film; Example 5, cast polypropylene film; Example 6, polyethylene terephthalate film.
[0048] 3. See Table 1 for the formula of matte coating agent.
