摘要
以环氧丙烯酸酯为单体,不饱和笼型倍半硅氧烷(POSS)及N-对甲苯基马来酰亚胺(NPTM I)为耐高温改性剂,选择合适的氧化还原体系及其他助剂,制成耐高温厌氧胶,并对其性能进行了相关测试。结果表明,此厌氧胶剪切强度最高达20 MPa,在200℃剪切强度保持率为75%左右,耐高温性能良好。
Using epoxyacrylates as the monomers, unsaturated polyhedral oligomeric silsesquioxane （POSS） and N-p-tolylmaleimide （NPTMI） as the high temperature resistant modifier and selecting a suitable redox initiating system and some other auxiliaries, the high temperature resistant anaerobic adhesive was prepared. The correlated properties of these adhesives were measured. The results showed that the maximum shear strength of the anaerobic adhesive is 20 MPa, and is conserved about 75% compared with room temperature at 200 ℃. This anaerobic adhesive has well high temperature resistant property.
