A kind of release paper embossed board and its manufacturing method

Abstract

The invention discloses a release paper embossed board and a method for manufacturing the same. The method includes steps of a, selecting raw materials for release paper; b, adding heat-resistant agents to the raw materials after the step a is completely carried out and treating the raw materials; c, carrying out PE (polyethylene) film spraying work on the release paper after the step b is completely carried out; d, carrying out silicon coating work on the release paper after the step c is completely carried out; e, adding release coating layers after the step d is completely carried out; f, carrying out board shape embossing treatment on the release paper after the step e is completely carried out; g, carrying out slitting by the aid of slitter machines after the step f is completely carried out; h, ultimately carrying out packaging treatment after the step g is completely carried out. The release paper embossed board and the method have the advantages that the heat-resistant agents are added into the raw materials while pulping treatment is carried out, accordingly, the heat resistance and the stability of paper surfaces can be improved, board embossing operation in later periodscan be facilitated, and high-temperature deformation can be prevented; the non-silicon release coating layers are used, accordingly, the smoothness and the silicon coating impermeability of the release paper in board embossing procedures can be improved, the release paper embossed board is convenient to integrally form, and popularization and utilization can be facilitated.

Description

technical field [0001] The invention relates to the technical field of processing a release paper embossed board, in particular to a release paper embossed board and a manufacturing method thereof. Background technique [0002] Release paper is also called release paper, anti-sticking paper, silicone oil paper. It is a kind of anti-adhesive paper that prevents the prepreg from sticking and protects the prepreg from contamination. The release paper is made of paper coated with anti-adhesive substances. Its type should be distinguished according to the material, thickness, elongation, and the difference between single and double sides. It can stick to the prepreg, but it is easy to separate the two; Have a chemical reaction with the resin system or pollute the resin system; when the ambient temperature and humidity change, the length and width of the release paper should remain unchanged, so as not to cause the release paper to wrinkle and cause the prepreg to wrinkle; it sho...

The release paper is made of paper coated with anti-adhesive substances. Its type should be distinguished according to the material, thickness, elongation, and the difference between single and double sides. It can stick to the prepreg, but it is easy to separate the two; Have a chemical reaction with the resin system or pollute the resin system; when the ambient temperature and humidity change, the length and width of the release paper should remain unchanged, so as not to cause the release paper to wrinkle and cause the prepreg to wrinkle; it should have enough The compactness of the prepreg can prevent moisture from entering the prepreg through it; the elongation of the release paper should be consistent with that of the fiber after being drawn, so as to prevent the prepreg from being deformed or twisted due to asynchronous drawing during the preparation process ; Its thickness and mass per unit area are not easy to accurately control
