摘要
研制以醋酸乙烯酯(VAC)为单体,乙酰乙酰化聚乙烯醇(AA化PVA)为保护胶体的乳液为甲组分和含有甲酰胺基的溶液为乙组分的双组分胶粘剂,并测试了胶粘剂的粘接性能:初粘强度为6.4×10-3MPa、湿强度为7.84MPa、终强度为10.10MPa,表明该胶粘剂的初粘强、湿强度高于市售的白乳胶(聚醋酸乙烯酯乳液).
Adhesive of component A and component B is prepared,in which component A takes vinyl acetate as monomer,takes acetoacetylated polyvinyl alcohol as protective colloid,and component B contains formylamide,then its bond strength is tested.The result is that first splice strength is 6.40kPa,humid splice strength is 7.84MPa,final splice strength is10.10MPa,indicating that splice strength,humid splice strength of this tackness agent is better than general white glue(poly vinylacetate,PVAc-Em).
