Water-base gravure ink copolymer emulsion and binder

Abstract

The invention discloses a water-base gravure ink copolymer emulsion and a binder, allyloxy hydroxypropy sulfonate sodium aqueous solution is added into a mixed solution containing monomers, hydrophilic monomers, molecular weight regulator and ammonium persulfate of carboxyl and carboxyl functional group for preparing the emulsion by copolymerization , alkaline solution is then neutralized and alcohol solubilizing assistant is added to obtain water-base gravure ink copolymer emulsion and the binder. On the one hand, the water-base gravure ink copolymer emulsion and binder save a large amount of food, one the other hand, the water-base gravure ink copolymer emulsion and binder save reduce 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. The material is widely applied to tipping paper, has viscosity of 90-150 seconds and strong water absorptivity and slow-release function, and can keep the tipping paper from water absorption and deformation and meet the demands of the production of cigarette filter tip.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for cigarette filter tip pine paper, 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 of solvent is non-toxic, it still bel...

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
