Problems solved by technology

[0003] In the prior art, a kind of unbleached or bleached kraft softwood pulp is used as the raw material of papermaking fiber, and a kind of paper-making fiber with omnidirectional wrinkles is produced by free mode beating, pulping, papermaking on the Internet, on-machine wrinkling and drying. When the wrinkled kraft paper with wrinkle effect is used as the base paper of wrinkle adhesive tape products, it has the following defects: the base paper is not only easy to be broken during the first anti-adhesive coating process on the surface of the base paper, but also The coated anti-adhesive coating is easy to penetrate into the back of the base paper, thereby forming an anti-adhesive coating on both sides of the base paper, which makes it impossible to carry out the next coating and adhesive process on the back of the base paper with the anti-adhesive coating formed. Therefore, both sides The base paper that has an anti-stick coating at the same time is scrapped and cannot be used

Embodiment Construction

[0020] refer to figure 1 100% bleached softwood kraft pulp commercial pulp board is subjected to pulping treatment in the hydropulper 1, and the pulp after the pulping treatment is sent to the 1# pulp storage tank 2, and then sent to the trough beater 3 for Beating in a viscous way, the beating degree of the pulp is 45°SR-55°SR, and the pulp is sent to the 2# water solution that has been applied with the PAE-LT papermaking wet strength agent (cationic polyamide epichlorohydrin polymer) aqueous solution. Fully and uniformly mix with the PAE-LT papermaking wet strength agent aqueous solution in the stock tank 4 . According to the wood pulp kind selected by the present invention and the beating method thereof, a kind of PAE-LT papermaking wet strength agent (the product produced by Tongli Chemical Factory in Shijiazhuang, China) applied in the 2# pulp storage tank 4 can be quickly and efficiently It is absorbed and retained by the negatively charged pulp fibers, and undergoes a ...

Abstract

A paper substrate for the crepe adhesive belt is made up of the conifer wood through breaching, pulping by sulfate, beating, adding wet strengthening agent, shaping paper, craping, drying, winding, coating impervious colloid, drying and winding.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and relates to a production method of base paper for crepe adhesive tapes. Background technique [0002] A wrinkle adhesive tape product used as a masking material in the fields of automobile manufacturing and maintenance, construction and decoration, etc., consists of a release layer, a wrinkle base paper and an adhesive layer. Wrinkled base paper is a main raw material for wrinkled adhesive tape products. The wrinkled base paper used in wrinkled adhesive tape products requires that its paper surface have obvious fine and irregular wrinkled lines, and the elongation rate is 10%-15%. When the first layer of anti-sticking coating is applied on the surface, the base paper not only does not break, but also has the ability to prevent the anti-sticking coating from penetrating from the paper surface to the back of the base paper. [0003] In the prior art, a kind of unbleached or bleached kraft s...
