Lead core rubber support added with hindered phenol antioxidant
The invention discloses a lead core rubber support added with a hindered phenol antioxidant. The lead core rubber support comprises an upper connecting plate, a lower connecting plate, an upper innersealing steel plate, a lower inner sealing steel plate, a rubber sheet, a stiffening steel plate, outer-layer rubber and a lead core; the lead core is arranged in the middle between the upper connecting plate and the lower connecting plate; a plurality of connecting bolts are arranged at the periphery of the lead core; the plurality of bolts are circularly arranged, and two ends of the plurality of bolts are fixedly connected with the upper connecting plate and the lower connecting plate; and the lower inner sealing steel plate, a buffer plate group and the upper inner sealing steel plate aresleeved on the lead core and the bolts. Oxygen has an important influence on corrosion of a support when a building is built in an offshore structure, and the problems of aging and cracking of rubberneed to be considered when a lead core rubber shock insulation support for foundation shock insulation is designed for earthquake resistance; and in order to improve the durability of the rubber, antioxidant-hindered phenol antioxidant is added into the rubber, so that the durability of the support is integrally improved.
本发明公开一种加入受阻酚类抗氧剂的铅芯橡胶支座，包括上连接板、下连接板、上内封钢板、下内封钢板、橡胶片、加劲钢板、外层橡胶和铅芯；所述上连接板和下连接板之间的中部设有铅芯；所述铅芯外围设有多个连接螺栓；多个螺栓呈圆形布置，多个螺栓两端与上连接板和下连接板固接；在铅芯和螺栓上套设有下内封钢板、缓冲片组、上内封钢板。在近海结构建造建筑物时氧对于支座的腐蚀有着重要的影响，在进行抗震设计时基础隔震用铅芯橡胶隔震支座就需要考虑到橡胶的老化以及开裂问题，为提升橡胶的耐久性，则采用在橡胶中加入抗氧化剂‑受阻酚类抗氧剂整体提高发明支座的耐久性。
