Problems solved by technology

At present, most of the printability modifiers widely used in paper are modified adipaldehyde, PAPU, and ammonium zirconium carbonate products. The products contain free formaldehyde or ammonia odor, which will cause harm to the workers in the workshop, and the water resistance efficiency is low. There are limitations in the improvement of paper printability

Abstract

The present invention belongs to the field of papermaking additives, in particular to a paper printability modifier and a preparation method therefor. The paper printability modifier contains the following ingredients in parts by weight: 50-100 parts of zirconyl chloride, 70-120 parts of acetate, 50-100 parts of glacial acetic acid, 0.03-0.08 part of stabilizer and 500-800 parts of water. The paper printability modifier is an inorganic salt high polymer product designed in view of the current coated paper printability, the product is formaldehyde-free and ammoniacal-odor-free, and a prepared coating has better and more stable rheology; the product is cured once discharged from a machine, and can efficiently enhance the water-resistant effect of paper, increase the reproducibility of dots during printing, make printing colors brighter, effectively decrease the number of printing spots, improve ink absorption ability, and alleviate or effectively solve the problems of printing ink staining.

Description

technical field [0001] The invention belongs to the field of papermaking auxiliary agents, in particular to a paper printing suitability improver and a preparation method thereof. Background technique [0002] The printability of paper is the performance that paper and cardboard should have, and it is the general term for all paper properties that affect the quality of printed matter. It mainly includes printing smoothness, ink acceptance performance, mechanical properties, optical properties, etc. When the coated paper is printed, it will encounter problems such as ink absorption and wet nap strength; if the ink absorption is too high or too low, the printed graphics will be dull or appear spots; the wet nap strength may be stained Printing layout and drum, white dots appear on the print. If chemicals with water resistance are added during the coating process, the optical, liquid resistance, wet nap strength and other properties of the coated paper can be effectively impr...
