Rubber composite material for waterstop and preparation method of rubber composite material

The invention discloses a rubber composite material for a water-stop belt and a preparation method of the rubber composite material. The rubber composite material for the water-stop belt is prepared from the following raw materials: rubber, carbon black, white carbon black, inorganic cost-reducing filler, an assistant crosslinking agent, an activating agent, an anti-aging agent, a plasticizer, a vulcanizing agent and an accelerant. The rubber is natural rubber and polybutadiene rubber. The rubber composite material for the water-stop belt has good appearance shape retentivity in the microwave hot air vulcanization process of preparing the rubber water-stop belt, and has good anti-reversion capability in the high-temperature vulcanization process. 本发明公开了一种止水带用橡胶复合材料及其制备方法，制备该止水带用橡胶复合材料的原料包括：橡胶、炭黑、白炭黑、无机降本填料、助交联剂、活化剂、防老剂、增塑剂、硫化剂和促进剂；所述橡胶为天然橡胶和聚丁二烯类橡胶。本发明的止水带用橡胶复合材料在制备橡胶止水带的微波热空气硫化过程中具有良好的外观形状保持性，在高温硫化过程中具有良好的抗硫化返原能力。
