摘要/Abstract

摘要：

采用正交实验法,探究在水基中三苯基甲烷-4,4′,4″-三异氰酸酯(TTI)交联聚乙烯醇(PVA)的反应。TTI是直接用列克纳胶(JQ - 1)为原料,利用其与PVA交联反应产物的不溶性和体系的压缩剪切强度等性能判断该反应的进程。结果表明,TTI的加入较大幅度地提高PVA胶水的粘结性能和耐水性能,尤其突出的是颜色为稳定的乳白色。

Abstract:

It was studied by the orthogonal matrix experimental method ,to the curing reaction of polyvinyl alcohol (PVA) by triphenylmethane -4,4′,4″triisocyanate(TTI) in water basal body. The Leiknonat(JQ-1)adhesive was a substitute material for TTI. The degree of the curing reaction was detected on the basis of the water-resistance of products and compressive shearing strength.Results showed that it was found that adding of TTI improve greatly the capability of cohesiveness and water resistance of polyvinyl alcohol glue. Especially, its color was steady going ivory white.
