Embodiment Construction

[0021] The present invention will be described in more detail below in conjunction with the examples, but the present invention is not limited thereto.

[0022] Take a certain amount of water-soluble polymer, calculate the amount of plasticizer that needs to be added according to the ratio between it and the plasticizer, and calculate the reaction time and the ratio according to the effective content and ratio of the water-soluble polymer and plasticizer. Solid content, finally uniformly diluted with water to 15% solid content. The following formula, through the addition of plasticizers and cross-linking agents, changes the film-forming properties of water-soluble polymers, polymerizes suitable adhesion and film-forming properties, and can be used as a crepe agent in toilet paper dryer coatings.

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 ...
