Problems solved by technology

This kind of glue that can be produced and formulated in China is made of toluene as a solvent, heated to dissolve EVA hot-melt resin, and then compounded with petroleum resin, microcrystalline wax, terpene resin, rosin, etc., because there is a large amount of toluene, so Non-green and environmentally friendly glue is not welcomed by production workers, nor is it accepted by foreign merchants

Abstract

The invention relates to the field of the high milecular polymerization emulsion type glue water, in particular to a method for preparing water-soluble hot melt adhesive glue water, The method for preparing the water-soluble hot melt adhesive glue water is characterized in that filling materials and water with calculated amount are added into a blending pan; a stirring motor is started to perform rapid stirring; auxiliary agents are added into the blending pan, such as an anti-foaming agent, an anti-mildew agent, an emulsifying agent, a dispersing agent, etc.; after being stirred for a period of time, the stirring speed is slowed down, EVA emulsion is added; then an anchoring agent is added; and the water-soluble hot melt adhesive glue water is prepared through even stirring. Compared with the prior art, the method has the advantages of simple process and low cost, and the study keeps the development direction of the domestic international high milecular polymerization on track, is market oriented, fills the gap in our country, meets the urgent requirements of the market, can conform to the requirement of the production process in the industrialization, can produce novel hot melt adhesive glue water which is free of environmental pollution, three-waste pollution and aquosity, does not contain organic solvent, is nontoxic and non-explosive and has no danger for combustion, therefore, the study is worthy of popularization and application.

Description

[technical field] [0001] The invention relates to the field of technical macromolecular polymerization emulsion type glue, and specifically provides a preparation method of water-soluble hot-melt glue. [Background technique] [0002] With the rapid development of my country's medical equipment and food industry, there is a great need for an emulsion-type heat-sealing glue that takes ethylene-vinyl acetate copolymer resin as the base material for further processing. Disposable medical supplies such as syringes, infusion sets, medical gauze, sterile cotton, etc. must be strictly sterilized and packaged before reaching the hands of medical workers. One side of this packaging material is a transparent plastic film or composite film, and the other side is paper printed with explanatory text such as product name, specification and brand. This kind of paper is easy to tear by hand. [0003] The plastic film is usually a PVC or PE composite film. To bond the paper to the PE composi...
