提高脲醛树脂胶粘剂耐水性的研究

Study on raising water resistance of urea-formaldehyde resin adhesive

研究旨在筛选提高脲醛树脂胶粘剂耐水性的最佳改性物质。采用在合成脲醛树脂时,加入改性物质使之产生共聚体,从而提高脲醛树脂胶粘剂的耐水性。结果表明,加入三聚氰胺或三聚氰胺加聚乙烯醇改性的脲醛树脂胶粘剂,耐水性提高较大。

Objective of this study is to chose best modified materials to raise the water resistance of UF resin adhesive.The method is to add modified material in synthesizing UF resin adhesive,let it produce copolymer,thus to raise the water resistance of UF resin adhesive.The result showed that the best 2 modifiers screened were melamine and melamine+polyvinyl alcohol.
