Abstract
Methyl methacrylaten (MMA) was used to solution graft onto and modify chloroprene rubber (CR) to improve its adhesive strength. And chlorinated polyethylene (CPE) and magnesium oxide (MgO) were added to the optimum formula system of CR/MMA adhesive to prepare a better adhesive effect of CR/MMA/CPE /MgO adhesive dedicated to bonding UHMWPE and 45# steel. The performance of adhesive film was analyzed by Infrared spectroscope (IR), X-ray diffraction (XRD) and Comprehensive thermal analysis (TG-DTG). The results show that CR being grafted and modified by MMA and adding CPE and MgO in the optimum formula of CR-MMA adhesive can improve itself bonding effect of glue solution and the wetting effect of glue solution onto bonding interface, and all helped to improve bonding strength. Adding 18% of CPE and 8% of MgO (in relation to CR) in the optimum formula of CR-MMA which bonding strength is up to 0.8013MPa could make the prepared composite adhesive’ s bonding strength reach 1.2048MPa and heat resistance temperature be up to about 200°C.
