Abstract

The invention relates to a labeling glue for glass bottles and a preparation method thereof. In parts by weight, the labeling glue is prepared from raw materials comprising the following components: 10-20 parts of casein, 45-65 parts of polyvinyl alcohol aqueous solution, 3-9 parts of synthetic emulsion, 1-6 parts of starch, 10 parts of water -20 parts, 0.2-0.8 parts of ammonia water, 0.05-0.8 parts of defoamer, 0.01-0.5 parts of adhesion promoter; the mass percentage of polyvinyl alcohol in the polyvinyl alcohol aqueous solution is 10-30%; the synthetic emulsion Prepared from raw materials including the following components: polymerized monomers, emulsifiers, water, pH regulators, buffers, initiators, alkalis; the polymerized monomers are selected from butyl acrylate, styrene, methyl methacrylate At least one of ester, hydroxyethyl acrylate and N-methylol acrylamide. It also has a good labeling effect when it is used for quick labeling of glass bottles. The labeling process does not draw, the drying time is fast, and the corners are not warped.

Description

technical field

[0001] The invention relates to the field of labeling glue, in particular to a labeling glue for glass bottles and a preparation method thereof. Background technique

[0002] The labeling glues used for soy sauce bottles and similar glass bottles mainly include casein glue and polyvinyl alcohol starch glue. Casein glue is also called casein glue or casein glue. The main components of polyvinyl alcohol / starch adhesive are polyvinyl alcohol and starch. The adhesive has a simple process, low cost, moderate viscosity, good mechanical properties, high strength, degradable products, no pollution, and strong practicability. .

[0003] When using the above glues for labeling on glass bottles, if they run on a slow labeling machine, they perform well, but if they are applied to a fast labeling machine, there will be some defects, for example: There will be a lot of drawing when running on the standard machine, and the polyvinyl alcohol starch glue will have poor bo...
