Abstract

The invention discloses glass mildew-proof lining paper and a preparation method thereof. The preparation method comprises the following steps: S1, carrying out chemical cooking pulping, oxygen delignification, hydrogen peroxide bleaching, washing and pulping on fiber raw materials; S2, adding auxiliary materials for pulp preparation, then performing papermaking, and obtaining wet page paper; and S3, sequentially carrying out pre-drying, coating, post-drying and calendering treatment on the wet page paper to obtain the glass mildew-proof lining paper, wherein the source of the fiber raw material is three residues conforming to FSC certification; and the fiber raw materials comprise 30-40 parts by weight of coniferous wood and 60-70 parts by weight of broad miscellaneous wood. The prepared glass mildew-proof lining paper is smooth and fine in surface, the PH of finished paper is acidic, the wet tensile force is large, the size stability is good, the appropriate surface absorptivity is achieved, glass (especially high-end glass) stripping is easy after the glass mildew-proof lining paper is used, and the product quality meets the national standard of glass protection packaging paper.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a glass mildew-proof backing paper and a preparation method thereof. Background technique [0002] With the rapid development of my country's electronics industrialization and building materials industry, the production volume of glass required for high-end decoration and LCD screens used in the electronics industry is also increasing, and its demand for protective packaging paper during transportation and storage The volume is also increasing. [0003] Based on the special purpose of glass protective wrapping paper, the anti-mildew liner paper for high-end glass requires good uniformity, high surface strength, suitable moisture absorption performance, fine and smooth surface, and a high degree of adhesion to the contact surface of glass during use. It must not only have good wet strength and high tensile force, but also be flexible, easy to peel off and not cut paper after u...
