Abstract

The invention discloses an adhesive and a preparation method for an automatic glue spraying system for beer bottle label clamp printing, belongs to the technical field of adhesives, and is made of the following raw materials in parts by weight: 50-100 parts of polyvinyl alcohol , 200-300 parts of white dextrin, 20-50 parts of urea, 5-10 parts of cross-linking agent, 2-4 parts of defoamer, 1-4 parts of Kason, 5-10 parts of ammonia water, 450-500 parts of water. The adhesive of the present invention is a patented adhesive used for beer bottle labeling machines. It has the advantages of low viscosity, strong adhesion, and fast conjunctival speed. A high-speed glue gun is used to spray the glue onto the groove of the label plate. It avoids the phenomenon of bubbling and wrinkles on the label of the beer bottle caused by the label not being coated with glue at the groove.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive used in an automatic glue spraying system for beer bottle label clamp printing and a preparation method thereof. Background technique [0002] Labeler is a device that sticks paper or metal foil labels on specified packaging containers with adhesive. Labeling machines are an integral part of modern packaging. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has changed from the backward situation of manual and semi-automatic labeling to the pattern of automated high-speed labeling machines occupying the vast market. However, for labeling machines with higher production requirements, firstly, the label taking plate passes through the rubber roller and takes glue from the rubber roller. Next, finally apply the label to the container at the predetermined position. T...
