Abstract

The invention discloses gravure glue. According to the gravure glue, a mixed monomer, an initiator, an emulsifier, a dispersing agent and water are used as raw materials. The dosage of the initiator is 0.2%-0.4% of the weight of the mixed monomer, the dosage of the emulsifier is 1%-2% of the weight of the mixed monomer, the dosage of the dispersing agent is 3%-6% of the weight of the mixed monomer, and the dosage of the water is 90%-110% of the weight of the mixed monomer. The mixed monomer is prepared from, by weight, 35%-65% of styrene, 25%-60% of butadiene and 5%-15% of ethyl acrylate. The bonding firmness of SBR latex and the fast permeability of acrylic based emulsion are combined together; paper using the gravure glue is good in aluminum layer and printing ink firmness, and the surface scraping phenomenon of the paper is avoided; besides, certain folding resistance is achieved, and the quality of finished printed products is improved.

Description

technical field [0001] The invention belongs to the field of paper printing processing and relates to a gravure glue. Background technique [0002] As a kind of printing process, gravure printing has the advantages of thick ink layer, bright color, high saturation, high printing plate durability, stable quality of printed products, fast printing speed and other advantages in the field of printing, packaging and graphic publishing. occupies an extremely important position. [0003] However, due to the particularity of the gravure printing method, the paper produced by the general gravure glue (styrene-butadiene latex) is prone to the phenomenon of "reflecting light", which is also called rubbing. The metal effect of such paper after printing is very poor, and the surface is dull, which seriously affects the appearance of the printed product. Contents of the invention [0004] In order to solve the above problems, the present invention provides a kind of gravure glue, whic...
