Embodiment 1

[0019] a 100% pure Canadian northern wood pulp is decomposed and beaten to obtain a slurry with a concentration of 3.5% and a degree of percussion of 18oSR;

[0020] b Then the polyester chemical fiber is decomposed by a deflagging machine, and mixed with the slurry obtained in step a to obtain a mixed slurry with a concentration of 2%, and the addition of the polyester chemical fiber is 3% of the total mass of the mixed slurry;

[0021] c. Add 3.0% of the total weight of the mixed slurry into the mixed slurry and mix it evenly with an appropriate amount of polyethylene oxide, and then form it through the inclined wire papermaking network, press for dehydration, and dry in a large cylinder (the surface temperature of the dryer is controlled at 107 ℃ -113°C range), coiling, rewinding and cutting to obtain 28g / ㎡ base paper for papermaking;

[0022] d After the base paper is dipped by the coating machine, it is coated with latex with a glass transition temperature of minus 27°C, ...

Abstract

The invention relates to a production process of Japanese paper adhesive tape base paper. The production process includes steps: a pure wood pulp is subjected to defibering and pulping to obtain size with concentration to be 3.5-4.0% and beating degree to be 18-20 oSR; b polyester chemical fibers are subjected to defibering and mixed with the size obtained from the step a to obtain mixed size with concentration to be 2-2.5%, wherein the filling quantity of polyester chemical fibers is 2-3% of the total mass of the mixed size; c wet strength agents and polyethylene oxide are filled into the mixed size and evenly mixed, then a net portion is formed through inclined wire papermaking, and after squeezing for dehydration, drying in a vat, reeling and rewinding slitting, a piece of papermaking base paper is obtained; and d the base paper is soaked by aid of a coating machine and then is coated with adhesives, the gluing amount is controlled to be in a 10-12g / m<2> range, and after drying, reeling and slitting rewinding, the Japanese paper adhesive tape base paper is obtained. The Japanese paper adhesive tape base paper is soft, high in longitudinal tensile strength and good in water seepage resistance and high temperature ageing resistance.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production process for washi tape base paper. Background technique [0002] Washi tape base paper is a special paper with high technical content and high added value. Washi tape base paper, weight: 38±3 grams, specification: roll width 950mm. The base paper of washi tape used in China mainly depends on imports, and there are few domestic manufacturers. At the same time, the base paper of washi tape produced in China has disadvantages such as poor softness of paper, low degree of anti-aging at high temperature, and high production cost. Contents of the invention [0003] Due to the defects in the prior art, the present invention provides a production process for washi tape base paper. The washi tape base paper obtained by the process is soft, has a longitudinal tensile strength of not less than 25N / cm, and has good water seepage resistance, High-temperature aging resist...
