摘　　要：以磷酸二氢铵、四乙基溴化铵以及硅烷偶联剂为改性剂,对重质碳酸钙进行表面化学改性,提高其补强性,拓宽重质碳酸钙的应用领域。在再生橡胶中的应用实验显示,与以未改性重钙粉为填充剂的再生橡胶相比,改性重质碳酸钙填充再生胶的力学性能有明显的提高,补强性与轻钙粉的效果相当。Ammonium dihydrogen phosphate,tetraethylammonium bromide and silane coupling agent were used as modifiers to modify the surface of heavy calcium carbonate to improve its reinforcing properties and broaden the application field of heavy calcium carbonate.Application experiments in recycled rubber showed that the mechanical properties of the modified heavy calcium carbonate filled regenerated vulcanizate were obviously improved compared with the unmodified one;the reinforcing effect was equivalent to that of light calcium powder.

关 键 词：改性重钙粉 重钙粉 轻钙粉 填充 橡胶力学性能
