Abstract

Raw paper for printing Japanese paper adhesive tapes is prepared from following raw materials: long-fiber wood pulp, short-fiber chemical mechanical wood pulp, bamboo pulp, a filling material, a wet-strength agent, coating latex and an extract liquid of cactus. The raw paper is prepared through the steps of performing pulping treatment, adding additives to the pulp, supercooling the pulp, performing papermaking, coating the paper, drying the paper and performing press polish and cutting to obtain the raw paper. The raw paper for printing Japanese paper adhesive tapes has excellent surface flatness, high printing clearness, good printing effect, excellent softness, excellent dry and wet strengths, excellent delamination resistance strength and anti-tear performance, excellent water- and solvent-resistant performances and excellent anti-radiation performance and temperature resistance. The method can reduce aging in the raw paper for printing Japanese paper adhesive tapes and prolonging the service life of the raw paper for printing Japanese paper adhesive tapes.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to base paper for printing more than one adhesive tape and a production method thereof. Background technique [0002] Printing and paper tape base paper is the special technical supporting paper for the production of washi tape in the adhesive industry. Printing and paper tape is mainly used for masking tapes for high-temperature baking varnishes such as automobiles, furniture, and aircraft that require printing. It has been used in baking varnish and decoration industries. Gradually replace traditional masking tape. [0003] Printing and paper tape base paper has high performance index requirements, complex manufacturing process, and high technical difficulty. At present, the printing and paper tape base paper on the market has poor printing effect, poor flexibility, poor radiation resistance, water resistance and temperature difference, and tear resistance. Therefore, there i...
