Problems solved by technology

[0003] When using the above glues for labeling on glass bottles, if it runs on a slow labeling machine, it performs well, but if it is 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 adhesion such as warping caused by too slow drying time

Abstract

The invention relates to a labeling adhesive for glass bottles and a preparation method of the labeling adhesive. The labeling adhesive is prepared from the following raw materials in parts by weight:10-20 parts of casein, 45-65 parts of a polyvinyl alcohol aqueous solution, 3-9 parts of a synthetic emulsion, 1-6 parts of starch, 10-20 parts of water, 0.2-0.8 part of ammonia water, 0.05-0.8 partof a defoaming agent and 0.01-0.5 part of an adhesion promoter. The mass percent of polyvinyl alcohol in the polyvinyl alcohol aqueous solution is 10-30%. The synthetic emulsion is prepared from the following raw materials: a polymeric monomer, an emulsifier, water, a pH regulator, a buffer agent, an initiator and an alkali. The polymeric monomer is at least one selected from butyl acrylate, styrene, methyl methacrylate, hydroxyethyl acrylate and N-hydroxymethyl acrylamide. When used for rapid labeling of glass bottles, the labeling adhesive also has a good labeling effect, does not cause wiredrawing in the labeling process, and is short in drying time and free of corner warping.

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...
