【摘要】：优选高活性环氧乙烯基酯树脂、过氧化甲乙酮-异辛酸钴氧化-还原引发体系、触变改性剂有机蒙脱土(OMMT)、增强填料石英粉和液体石蜡、硅烷偶联剂等助剂,制备了快固型环氧乙烯基酯锚固胶。结果表明:制备的锚固胶固化速率快,劈裂抗拉强度为14 MPa,抗弯强度为57 MPa,呈非碎裂破坏状态,抗压强度为80 MPa,粘结剪切强度为16 MPa,带肋钢筋拉拔强度为20 MPa。符合GB 50728—2011《工程结构加固材料安全性鉴定技术规范》中Ⅲ类锚固胶的标准要求,即使在冬季低温施工环境下也能起到快速锚固修复的目的。
[Abstract]:High activity epoxy vinyl ester resin, methyl ethyl ketone-isooctanoate cobalt oxidation-reduction initiator system, thixotropic modifier OMMTO, filler quartz powder and liquid paraffin were selected. The fast solid epoxy vinyl ester anchoring adhesive was prepared by silane coupling agent. The results showed that the curing rate of the prepared epoxy vinyl ester was fast, the splitting tensile strength was 14 MPA, and the bending strength was 57 MPa. The compressive strength is 80 MPA and the bond shear strength is 16 MPa. The drawing strength of ribbed steel bar is 20 MPA. It conforms to the standard requirements of Class 鈪，
