Study on the Wood Adhesive of Polyvinyl Alcohol Cross-linked by HDI
Using orthogonal experiment method, the preparation process conditions of the adhesive, such as the amount of OP-10, catalyst stannous octoate, crosslinking agent of HDI, the temperature of the synthetic reaction, the synthetic reaction time, and the amount of PVA were discussed. The results showed that the addition of HDI and the catalyst stannous octoate could greatly increase the water resistance, stability, and adhesive properties of the adhesive, thereby achieving the purpose of modifying the polyvinyl alcohol adhesive. Through the modification process can obtain milky stable product, which can be used in the construction industry for wood adhesives, and more environmental friendly.
