Production process of imitation reactive printing adhesive

Abstract

The invention relates to a production process for an imitated active printing adhesive. The production process comprises the following steps: opening an emulsifying kettle; adding peregal, butyl acrylate, acrylonitrile, styrene, acyclic acid, isooctyl, hydroxyethyl methacrylate, acrylamide and sodium dodecylbenzene sulfonate, emulsifying and stirring for 2.5 hours, and replenishing water to 1 ton; opening a reacting kettle; adding the peregal, sodium dodecylbenzene sulfonate, kerosene, ammonium persulfate, and bottom water; turning on electric heating, when the temperature of the reacting kettle rises to 85 DEG C, turning off the electric heating, and dropwise adding a raw material which is emulsified in the emulsifying kettle; simultaneously, dropwise adding the prepared initiator, namely sodium persulfate, for 2.5 hours; controlling the reacting temperature to be within 90 DEG C, and carrying out heat preservation for 1.5 hours; reducing the temperature to 60 DEG C, adding diluted ammonia, regulating the pH value of the solution to be between 6.5 and 6.7, adding a softener and a fastness accelerant, adding water to adjust to the controlled quantity of 2 tons, stirring uniformly for 5 minutes, and discharging the material. The production process has the advantages that the process is complete, the formula is novel and reasonable, the printing quality is greatly improved, the printing hand feeling is good, super-soft is achieved, the compatibility is improved, and the storage time is doubled.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a production process for imitation reactive printing adhesives. Background technique [0002] There are roughly three types of adhesives widely used at present, one is the adhesive with acrylate as the main body. The soft monomer is butyl acrylate, the softest is isooctyl acrylate, and the hard monomer is methyl methacrylate, styrene, acrylonitrile, etc. This type of adhesive film has high transparency and is currently the most commonly used adhesive. agent. The second is the adhesive with butadiene as the main body. The hard monomer is styrene (styrene-butadiene emulsion) and acrylonitrile (butadiene-nitrile emulsion). It is compounded with other high polymers to increase the strength of the film. This type of adhesive feels Soft, but easy to yellow, cheap and does not need to be baked to fix. The third is polyurethane adhesive, which is a polymer formed by polymerizing polyvalent is...

Problems solved by technology

The third is polyurethane adhesive, which is a polymer formed by polymerizing polyvalent isocyanate compound and polyether or polyester containing active hydrogen atoms. If it is polymerized with polyether, it is called polyether polyurethane, and its hydrolysis resistance is good. Soft to the touch, but poor in light and heat resistance

The formula of the imitation active adhesive produced before is not very perfect, and there are problems such as not enough softness, poor compatibility, and short storage time
