Problems solved by technology

When the release paper in the prior art is in use, it is very easy to generate static electricity, thereby affecting the use quality of the release paper; and the release paper used in the food field lacks antibacterial function, so many foods are not protected by special chemical additives. It is easy to be corrupted and deteriorated, causing great losses

Embodiment 1

[0023] A preparation method of antibacterial and antistatic release paper, comprising the following steps:

[0024] A. Fast-growing pine wood is directly shaved without peeling and then sulfite cooking and pulping is carried out. After DQP three-stage chlorine-free bleaching and washing, electronic-grade pulp with a whiteness of 84% is obtained. A beater is used at a temperature of 2.2%. Beat the pulp to 45.5°SR at the pulp concentration, and the wet weight of the pulp is 7.2g;

[0025] B, slurry preparation: add 12% calcium carbonate to the slurry prepared in step A and carry out slurry allocation in the slurry mixing tank;

[0026] C, papermaking: papermaking is carried out on the fourdrinier paper machine to obtain wet paper web after being diluted to a concentration of 0.9% by white water flushing;

[0027] D. Finished paper: glassine base paper is obtained through pressing section, front drying section, sizing, post drying section, calendering, coiling, and slitting;

Abstract

A preparation method of antibacterial antistatic release paper is disclosed. Fast-growing pine wood is used as a pulp raw material, and glassine base paper is obtained through papermaking with pulp and paper formation; then, the glassine base paper is soaked in an acetic acid solution, and dried and then subjected to corona pre-treatment, the base paper is coated with a mixed release agent, and then the base paper is dried to obtain the antibacterial antistatic release paper. According to the preparation method, an antioxidant, chitosan, an ultraviolet absorber and an antistatic agent are added into the mixed release agent, so that the release paper has very good antibacterial and antistatic effects, and has significantly improved aging resistance and ultraviolet resistance; the glassine base paper is soaked with the acetic acid solution, so that the antibacterial performance of the release paper is significantly improved.

Description

technical field [0001] The invention relates to the technical field of release paper, in particular to a method for preparing an antibacterial and antistatic release paper. Background technique [0002] Release paper, also known as release paper, anti-adhesive paper, silicone oil paper, is a kind of anti-adhesive paper that prevents prepreg from sticking and protects prepreg from contamination. The release paper is made of paper coated with anti-adhesive substances, and its type should be distinguished according to the difference in material, thickness, elongation, and single-sided and double-sided. When the release paper in the prior art is in use, it is very easy to generate static electricity, thereby affecting the quality of the release paper; and the release paper used in the food field lacks antibacterial function, so many foods are not protected by special chemical additives. It is easy to be corrupted and deteriorated, causing great losses. In order to overcome the...
