玻璃纤维网格布用乳液胶粘剂的研制

摘要

A styrene-acrylate emulsion adhesive for fiberglass mesh was prepared by polymerization method of pre-emulsified monomers. The effects of monomcr.emulsifier, initiator and reaction temperature were studied on the stsbility.water resistance,adhesion,viscosity and polymerization process.The optimum process conditions were determined. The results showed that when the miss ratio of soft and hard monomer was 47/53,the emulsifier and APS were 3% and 0.4% by weight of monomer respectively,SDS/OP -10 was 2/1.the polymerization temperature was 82~84 ℃ and reaction time was 2.5 hr,the porperties of styrene-acrylate emulsion were better.%采用予乳化聚合方法制备了玻璃纤维网格布用苯丙乳液胶粘剂.探讨了单体、乳化剂、引发剂、聚合反应温度等对乳液的稳定性、耐水性、粘接性、黏度及聚合反应过程的影响.确定了最佳的工艺条件.结果表明,当软硬单体质量比为47/53、乳化剂占单体的3%,mSDS/mOP-10=2/1,APS占单体的0.4%,聚合反应温度为82～84℃、反应时间为2.5 h时,制备的苯丙乳液综合性能最佳.
