Abstract:
      The compound formula of the horizontal force spread type rubber bearing was optimized，and the effects of the adhesive film thickness on the adhesion between the compound and steel plate and the ultimate horizontal shear performance of the rubber bearing were studied.The results showed that the vulcanizing reversion resistance and heat resistance of the compound could be significantly improved by blending of styrene butadien rubber（SBR）/natural rubber（NR） and combination of accelerator CBS and DTDM.The optimized formula of the rubber bearing compound was NR/SBR（blending ratio was 60/40）100，carbon black N774　35，zinc oxide　5，stearic acid　1.5，naphthenic oil　15，antioxidant RD　2，antioxidant 4010NA　2，sulfur　1，and accelerator CBS/DTDM（blending ratio was 4/1）　5. It was suitable that the primer coating adhesive film thickness was 10～15 μm，and surface coating adhesive film thickness was 25 ～ 30 μm. Under the conditions of 100% shear displacement，200% shear displacement，300% shear displacement and 400% ultimate shear displacement，the horizontal stiffness of the trial LNR 600 horizontal force spread type rubber bearing was 0.91，0.85，0.85 and 0.96 kN·mm-1 respectively，and all horizontal stiffness deviations were within ±15%，which met the design requirements.
