A kind of preparation method of cylinder sticking agent for crepe paper

Abstract

The invention relates to a preparation method of cylinder adhesive for crepe paper. The existing cylinder adhesive generally has defects such as poor film forming performance, poor film forming elasticity and poor remoistening performance and the like. By utilizing a water-soluble macromolecular polymer in a water phase, by adding a cross-linking agent and a plasticizer, the cylinder adhesive is prepared by virtue of local cross-linking of macromolecules and the compounding of the plasticizer. The cylinder adhesive prepared by the invention is stable in performance, has good adhesive force andfilm forming performance, can adjust the remoistening performance and softness of a film and can well improve the wrinkling performance of the crepe paper.

Description

technical field

[0001] The invention relates to the field of preparation of cylinder sticking agent, in particular to a preparation method of the cylinder adhesive which is sprayed on the cylinder to help paper wrinkle during the production of crepe paper. Background technique

[0002] When producing crepe paper, the paper is dried by a drying cylinder, and it needs to have a strong impact with a scraper to produce wrinkles, improve the softness, water absorption, bulk and other properties of the paper, and at the same time obtain a good feel. This requires proper adhesion between the paper sheet and the dryer, especially in the production process of medium and high-speed paper machines, the adhesion of the pulp itself is not enough to meet the production needs, and it is necessary to rely on dryer coating additives ( Including the use of cylinder sticking agent, stripping agent and improver) to adjust, so as to control the thickness of the lines, the depth of wrinkles, the ...
