Adhesive, preparation and use thereof

Abstract

The present invention provides an adhesive for labeling. The adhesive comprises 1-40% animal glue, 0-45% emulsion, 0-20% starch, 5-40% diluting agent, 0-10% cross-linking agent, 0-5% thickening agent, 0.001-2% additive and 20-50% water. The adhesive of the present invention has the advantages of good primary adhesion, low solidifying point, good waterproof property, high stability against enzymatic hydrolysis and washability in elevated temperature water without alkali. It commendably meets the demands of speeding the manufacture rate, improving the manufacture qualified rate and recovering of containers, and specially suits for labeling of beer bottles.

Description

technical field

[0001] The invention relates to an adhesive, in particular to an adhesive prepared from animal glue and its application. Background technique

[0002] With the development of the beer industry, its packaging requirements and production speed continue to increase, and the requirements for adhesives for labeling are also increasing. Aircraft performance, running speed and water resistance have also been continuously improved. Both starch glue and casein glue are natural polymer adhesives, and casein glue has the best performance. However, with the continuous improvement of production speed and production qualification rate of manufacturers in recent years, casein gum has been greatly challenged. At the same time, with the increase in the demand for dairy products and the popularization of casein gum technology, the demand for casein as a raw material also increases a lot, thus causing the price of casein to rise. Casein glue is also limited by the properties...
