IMPROVED ADHESIVE COMPOSITION Russian patent published in 2016 - IPC C09J103/02 

FIELD: chemistry.

SUBSTANCE: invention relates to adhesive compositions, which are mainly applied in paper and cardboard industry, obtaining adhesive composition, to dry premix composition and method of its obtaining. Aqueous adhesive composition contains at least 7 and mot more than 30 wt % of adhesive component. Adhesive component includes at least one polyvinyl alcohol, and/or at least one dextrin, and/or at least one starch. Adhesive composition additionally includes carbomer and in case of necessity boron compound. PH of adhesive composition constitutes not more than 13.0. In case if starch and boron compound are present in adhesive composition, more than 91.0% of the total starch in composition are in form, non-soluble in cold water. In accordance with invention obtained are: solid dry premix, suitable as base for adhesive composition, and methods for obtaining solid dry premix or adhesive composition and product, in which all of them are used to form adhesive connection with substrate.

EFFECT: invention makes it possible to prepare adhesive composition, viscosity of which is easily predicted and regulated, which makes application of starch more effective, demonstrates Newtonian rheology, preferably in the process of corrugating.
