The present disclosure provides a resin modified starch adhesive. The resin modified starch adhesive comprises, by weight, 100 parts of a dry starch, 300-500 parts of deionized water, 20-40 parts of an epoxy resin, 5-10 parts of an azido polyether, 1-2 parts of 3, 5-diamido-1, 2, 4-triazole, 1-3 parts of a cyanoacrylate, 5-10 parts of sodium hypochlorite solution, 3-8 parts of sodium tripolyphosphate, 2-5 parts of hydrotalcite, 3-8 parts of kaolin and 1-4 parts of sodium sulfate. The starch adhesive is prepared by modifying an oxidized starch emulsion with an epoxy resin modified by the azido polyether to introduce reactive functional groups and water-resisting five-membered ring structures, thus the shear strength and the water resistance of the adhesive are greatly improved.

Resin modified starch adhesive and preparation method thereof

The invention belongs to the technical field of binders, and particularly relates to an environment-friendly anti-oxidation carton adhesive and a preparation method thereof. The adhesive comprises the following components: dry starch, p-aminophenol epoxy resin, hydrogen peroxide, borax, sodium dicyandiamide, dimethyl carbonate, phthalic anhydride polyester polyol, polyethylene terephthalate, triethanolamine and antioxidant. The anti-oxidant is a compound of hindered phenol, phosphite ester, and a metal ion chelating agent. The adhesive not only has high bonding strength, but also has the effects of non-discoloring, mildewing and the like when used for a long time.
