Investigation on modifying VAE adhesive by isocyanate
Hui Li · Chemical engineer · 2004
This paper introduced the way of modifying VAE adhesive by vulcabond. The technique and prescription for producing the adhesive were presented by studying on hydrolysis degree of VAE and the cross linking reaction with isocyanate. In addition, the effect of reaction temperature, hydrolysis degree,amount of vulcabond and the stuff upon the properties of adhesive was also discussed in the paper. It was shown that the properties of modified VAE adhesive had been improved greatly, such as the bonding property, heat resistance and water resistance. The modified adhesive could be used in the adhesion of lignum, paper textile with the plastic and so on.
