乙二醛-尿素-甲醛共缩聚树脂的结构与性能研究
|
摘要
以G(乙二醛)取代部分F(甲醛),合成了GUF[乙二醛-U(尿素)-甲醛共缩聚树脂];然后以此作为胶粘剂基体,制备了相应的GUF胶合板。着重探讨了原料配比对GUF黏度和固含量的影响,并对GUF的结构、相对分子质量及其分布进行了表征,同时对GUF胶合板的热压过程、固化性能、力学性能和F释放量等进行了测定。研究结果表明:合成GUF的最佳原料配比是n(G)∶n(U)∶n(F)=0.7∶1.0∶0.7,此时相应GUF胶合板的F释放量和力学性能均满足GB/T 9846.3—2004标准中的指标要求,并且该胶合板可在干燥状态下直接用于室内装修。
With G(glyoxal)replaced part F(formaldehyde),a GUF[G-U(urea)-F copolycondensation resin]was synthesized.Then,with GUF as matrix of adhesive,the corresponding GUF-plywood was prepared.The influences of raw material ratios on viscosities and solid contents of GUF were emphatically discussed.And the GUF’s structure,molecular weight and its distribution were characterized,as well as the some properties(hot-pressing process,curing properties,mechanical properties,and F-emission)of GUF-plywood were tested.The research results showed that the optimal raw material ratio of synthesizing GUF was obtained when n(G)∶n(U)∶n(F)was 0.7∶1.0∶0.7.Here,the F-emission and mechanical properties of corresponding GUF-plywood could all meet the index requirement in GB/T 9846.3—2004 standard,and the drying plywood could be used in interior trim.
