Temperature curing type adhesive and esterified modified tapioca preparation

Temperature curing type adhesive esterified modified tapioca starch and a preparation method, which belongs to the technical field of adhesive preparation. Currently the timber industry raw materials commonly used in adhesives are non-renewable. The present invention is mainly made of tapioca starch modified polyisocyanate adhesives, antioxidants, flame retardants, light stabilizers, ultraviolet absorbers, respectively, 80 parts by weight to 100 parts of modified tapioca starch adhesive, ~ 7 12 parts of component isocyanate, 0.5 to 1.5 parts of an antioxidant, 0.5 to 2 parts of a flame retardant, 0.02 to 0.2 parts of a light stabilizer, 0.5 to 1 part of an ultraviolet absorber, wherein the adhesive comprises a modified tapioca starch tapioca starch, polyvinyl alcohol, sodium lauryl sulfate, dodecenyl succinic anhydride. The present invention is a moderate viscosity, storage stable, slowly layered, simple preparation process and easy to operate, less time consuming; excellent water resistance, excellent bonding strength and easy industrial production.
