改性PVA/天然胶乳胶粘剂的研究

Investigation of modified PVA/natural rubber latex adhesive

将改性聚乙烯醇(PVA)作为天然胶乳胶粘剂的改性剂,研究其对天然胶乳胶粘剂的粘度、剥离强度及耐水性能的影响。研究结果表明:改性PVA的加入,显著地提高了天然胶乳的硫化速率,延长了胶粘剂的贮存时间,改善了其粘度、剥离强度及耐水性能。

The effects of modified PVA on the viscosity, peel strength, water resistance of natural rubber latex adhesive were investigated. The results showed that the vulcanization rate of natural rubber latex was significantly increased. The storage time of adhesive was extended and its viscosity, peel strength and water resistance were im-proved.
