摘要
以环氧树脂CYD-127和830为主体粘料,液体丁腈橡胶为增韧剂,多胺和聚硫醇加成物为固化剂,研制出能在低温下固化的结构胶粘剂。研究结果表明:在-10℃环境中,7d后其钢/钢拉伸抗剪强度为18.4MPa,能基本满足《混凝土结构设计规范》规范中的要求。
Structural adhesives cured at low temperature were prepared by using epoxy resin CYD-127 and830 as the main ingredient, CTBN as toughened agent, multi-amine and polymercaptan adduct as curing agent.The results showed that after cured at-10℃ for 7 days, tensile strength was 18.4MPa, which basically met the needs of design code for strengthening concrete structure.
