ADHESIVE BASED ON STARCH

摘要

A process is described for the preparation of an adhesive based on starch, wherein a biopolymer, which consists to at least 70 % of starch, and 1-40 % by weight water (with respect to starch) are mixed with a hydrolysis catalyst, the mixture is shaped mechanically at a temperature such that the hydrolysis temperature is not exceeded and, before use, the shaped starch is heated to at least the hydrolysis temperature. With this procedure an adhesive of low viscosity is produced which can be applied to the substrate to be glued, such as paper, glass, polyethylene and polypropylene.
