异氰酸酯-聚醋酸乙烯酯复合乳液木材胶黏剂的制备及耐水性能研究
Preparation and Water Resistance Study of Isocyanate-polyvinyl Acetate Composite Emulsion Wood Adhesive
摘要
Abstract
Wood adhesives with high water resistance were prepared by combining isocyanate with Polyvinyl acetate.FTIR was adopted to characterize the composite emulsion film.The influence of various isocyanate,the amount of polymethylene polyphenyl polyisocyanate(PAPI)on the viscosity,water absorption and wet strength were investigated respectively.The results indicated that polyurethane-urea structure with strong hydrogen bonding effects was formed in the composite emulsion film after the combining of isocyanate,with the increasing content of PAPI,the viscosity and wet strength increased,while equilibrium water absorption rate decreased at the same time interval.PAPI is conducive to improving the water resistance of the composite emulsion film.关键词
