Problems solved by technology

[0004] 99105486.5), improved casein glue (Chinese patent: 201210081889.1), mainly polyvinyl formal glue and protein glue, these products cannot be pasted on plastic bottles, because they are polar substances, they are not suitable for non-polar plastics such as plastics. The material affinity is poor, and the glue will fall off the bottle directly after drying, which will affect the aesthetics of beer; if the traditional paper-plastic film glue is used, although the label can be pasted, its cohesion is very small, which is not suitable for high-speed automatic labeling , which brings a lot of trouble to the development of beer production enterprises

Abstract

The invention provides an adhesive for adhering a paper label to a plastic bottle through an automatic labeling machine and a preparation method thereof, and relates to the field of high molecular adhesives. The adhesive is prepared by performing a reaction on deionized water, an emulsifying agent, rosin, butyl acrylate, ethyl acrylate, methacrylic acid, methyl methacrylate, a crosslinking agent,a defoaming agent, a preservative and ammonia water according to a certain ratio, a certain technology and certain requirements. The adhesive is prepared by using water as a solvent and polymerizing acrylic monomers under the assistance of the reaction of high molecular materials, and is non-toxic, odorless and free of environment pollution; the label adhesive prepared by the preparation method provided by the invention is less affected by temperature difference, is wide in adaptability, smooth in labeling, low in consumption and non-toxic, and fully meets labeling requirements of high-speed and low-speed beer production lines at home and abroad.

Description

technical field [0001] The invention relates to the field of polymer material adhesives, in particular to an adhesive for plastic bottle environmental protection labels for automatic labeling machines and a preparation method thereof. Background technique [0002] At present, China's beer industry has become one of the industries with the fastest growth, the largest production and sales volume and the most intense competition in the world beer market. In the next five years or so, there is still room for greater growth in this market. For a long time, beer has been mainly packaged in glass bottles, especially in my country, the utilization rate of glass beer bottles is over 90%. However, the inherent defects of glass bottles have triggered a global upsurge in seeking cheap and suitable alternatives. New types of plastic PET beer packaging containers have emerged in Europe and the United States. my country has also continued to increase investment in this topic. Because the...
