| Abstract: | The cross linking modification of polyvinyl alcohol (PVA) adhesive was explored by adding diisocyanate (TDI) and borax. Using the orthogonal matrix experimental method, the effects of borax or TDI on the PVA adhesive were discussed. The reaction degree was determined by the water resistance of the products. A small amount of TDI and borax will greetly improve the water resistance of PVA film and adhesive strength of PVA adhesive. |
