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 present invention relates to the technical field of high molecular polymer emulsion type glue, in particular to a water-soluble hot-melt glue. In the preparation method of the water-soluble hot-melt glue, the water-soluble hot-melt glue contains binder, viscosity increaser, filler, organic silicon defoamer, organic silicon mildew preventive, other assistants and water, and the water-soluble hot-melt glue is characterized in that the components are calculated according to the total weight portion of the non-volatile ingredients which amounts to 100, the dosage proportion of the ingredients is as follows: 10 to 40 portions of binder, 10 to 30 portions of viscosity increaser, 20 to 60 portions of filler, 10ppm to 100000ppm of organic silicon defoamer, 1ppm to 10000ppm of organic silicon mildew preventive, 0.1 to 5 portions of assistants and 100 to 300 portions of water. Compared with the prior art, the water-soluble hot-melt glue fills the domestic gap in the field and is worth promotion and application.

Description

[technical field] [0001] The invention relates to the field of technical polymer emulsion type glue, in particular to provide 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 composite film, the paper must undergo special process...
