Embodiment 1
[0050] A bridge shock-absorbing bearing, such as figure 1 As shown, it includes a top plate 1, a stainless steel plate 2, a polytetrafluoroethylene plate 3, a middle steel plate 4, a rubber block 5 and a bottom basin 6 from top to bottom. The rubber block 5 is placed at the bottom of the bottom basin 6, the middle steel plate 4 is partly placed in the bottom basin 6, and a sealing ring 7 is arranged between the rubber block 5 and the middle steel plate 4.
Embodiment 2
[0052] The rubber block in embodiment one comprises the following components by weight:
[0053] 60 parts of natural rubber;
[0054] 30 parts of rare earth butadiene rubber, model Nd45, purchased from Korea LG Chem;
[0056] 1 part stearic acid;
[0057] Anti-aging agent BLE 1 part;
[0058] Carbon black N330 15 parts;
[0059] 0.5 parts of microcrystalline wax;
[0060] 2 parts sulfur;
[0061] Accelerator DM 0.5 parts;
[0062] 3 parts of plant extract;
[0063] 10 parts of calcium carbonate whiskers, model NP-CW2, purchased from Shanghai Fengzhu Composite New Material Technology Co., Ltd.;
[0064] 3 parts of dimethyldivinylsilane;
[0065] 2 parts of dibutyl sebacate.
[0066] The preparation process of plant extract is as follows:
