高性能丙烯酸类混凝土裂缝修补材料的制备
Study on Repairing Material Made of High Performance Crylic Acid Species for Concrete Pavement Cracks
摘要
Abstract
Under the conditions of methyl methacrylate (MMA) as main agent,butyl methacrylate (BMA) as toughening agent and epoxy resin as modifying agent,it applies the orthogonal experiment design to prepare the high performance crylic materials for concrete crack curing in the system of Benzoyl peroxide and amine.It analyzes the effects of every single component of the crack-curing materials on initial viscosity,tensile strength,breaking elongation and bonding strength to achieve the optimal proportions.It tests the ultraviolet aging property of the crack-curing materials and then draws out the experimental mechanism based on infrared analysis.The investigation results present that the crack-curing materials meet the requirements of reinforcement of concrete since the initial viscosity is 100 ~300 mPa · s,the curing time is about 1 h,the bonding strength of mortar samples reaches to 7.0 MPa and the tensile strength is above 30 MPa,as well as the other properties are significantly improved.关键词
