Study On Water Based Polymer-Isocyanate Adhesive For Wood Esterify To Corn Starch

The paper systematically studies the formulation of aqueous vinyl polymer solution isocyanate adhesive (API)桬sterify to corn starch. Corn starch adhesive main agent was made with the aid of reaction between corn starch and dibasic acid to form esterified corn starch suspension liquid, From the synthesis experiments of corn starch suspension liquid and synthetic rubber latex modification, the compositions of esterified corn starch suspension liquid are determined. From solvent experiments, suitable masking agent is selected. From the mixture experiments of base polymer with other modifiers and the optimizing experiments of the adhesiveformulation, final composition of API is gained. The results of the study indicated that physical and mechanical properties of three條ayer solid wood parquet and plywood bonded with the above-mentioned adhesive could meet with the national standard. In addition, the research result is of significant social and economical benefit.
