摘要
通过正交试验法，研制出特定的聚醋酸乙烯酯母液、丙烯酸酯乳液、丁苯胶乳液、醋酸乙烯－乙烯共聚乳液，以一定的比例混合形成柔性链段的嵌段主体，加入水溶性高分子乳液，构成水溶性高分子－异氰酸酯复合系模拼胶粘剂的主剂，再加上多元醇－异氰酸酯预聚体所形成的刚性链段的嵌段主体，混合形成嵌段共聚物．经生产性试验，该胶种是非甲醛系胶粘剂，且胶合强度形成快，耐水、耐老化能力强．
Developed acetic acid ethenyl ester,acrylic acid ester alkyl,butylbenzene,vinyl acetate ethylene were mixed in proportion to form the main flexibility chain through method of orthogonal test.Water was added into mixture to form water based polymer isocyanate adhesives,then added polylol isocyanate to form the main hardness chain.The test results showed that this glueing intensity was water tolerant and old resistant.
