Processing technology of water-base gravure ink copolymer emulsion

Abstract

The invention discloses a processing technology of a water-base gravure ink copolymer emulsion, the method of the processing technology comprises the following steps: first mixing allyloxy hydroxypropy sulfonate sodium with water, adding a certain amount of mixed solution consisting of vinyl acetate, tertdecanoic acid ethenyl ester, itaconic acid, hydroxyethyl acrylate and dodecyl mercaptan, heating the solution up to 60-70 DEG C, then adding a certain amount of ammonium persulfate aqueous solution for reaction to the temperature of 78-82 DEG C, starting dropwise adding the remaining mixed solution when the reflux stops, adding the ammonium persulfate aqueous solution every one-hour addition, adding the remaining ammonium persulfate aqueous solution upon the ending of the addition for heat preservation at the temperature of 90-95 DEG C, and then cooling to prepare the emulsion. The material is mainly used for preparing a water-base gravure ink binder that is applied to tipping paper. On the one hand, the prepared binder saves a large amount of food, and on the other hand reduces the use of organic solvents, thereby effectively avoiding the defects that the organic solvent is inevitably combustible and explosive, pollutes environment and jeopardizes health of production worker, and the environment-friendly requirements of the binder are met.

Description

technical field [0001] The invention relates to an adhesive, in particular to a processing technology of an adhesive emulsion of pine paper for a cigarette filter, and belongs to the technical field of adhesives. Background technique [0002] Alcohol-soluble cigarette paper glue is used as the binder of cigarette paper--tip paper gravure printing ink. The principle is to use the property of polyvinyl acetate to be easily soluble in ethanol containing part of water, and at the same time introduce butyl acrylic acid through emulsion copolymerization. Under the action of various factors such as ester plasticization, methacrylic acid solubilization, and nonylphenol polyoxyethylene ether solubilization, the linking material of alcohol-soluble cigarette paper (tip paper) gravure printing ink was prepared, and the linking material consumption per ton About 600 kilograms of 95% edible ethanol is used, and a large amount of ethanol is also used when preparing ink. Although this type ...

Problems solved by technology

In the early 1990s, in order to save a large amount of practical ethanol, we began to develop ethanol-free adhesives, such as the Chinese invention patent application CN90109256.8, which disclosed a "new water-soluble coating adhesive for tipping paper", using brown algae Sodium phosphate, sodium tripolyphosphate, sodium oleate, urea, styrene-butadiene latex, formaldehyde, water and defoamer are mixed in a certain proportion. Although the use of this adhesive saves a lot of practical ethanol, it adopts the current Materials such as formaldehyde that do not meet environmental protection requirements, on the basis of cigarettes being harmful to health, have added carcinogens. Long-term exposure will seriously endanger the health of production workers and smokers, and their use has been banned in many countries
