测试了定型剂在RTM树脂中的溶解性能。
And we also study the acetal structure and its influence of thermal stability of polyvinyl acetal which was used as toughening agent and tackifier.并对作为增韧剂和增粘剂的聚乙烯醇缩醛的缩醛结构对其热稳定性的影响进行了分析。
Epoxy resin is the common tackifier for polysulfide sealant. Adding epoxy resin into polysulfide sealant can exert an auxiliary effect on viscosity increasing.环氧树脂是聚硫密封胶常用的增粘剂,在聚硫密封胶中加入环氧树脂可以起到明显的增粘作用。
