水滑石/丁腈橡胶纳米复合材料的制备及性能研究

采用乳液复合法制备水滑石（LDHs）/丁腈橡胶（NBR）纳米复合材料，并对其结构和性能进行研究。结果表明：复合材料中LDHs均匀分散在NBR基体中；与NBR胶料相比，LDHs/NBR复合材料的物理性能和气体阻隔性能明显提高；当LDHs/NBR用量比为1/20且LDHs用量为1份时，LDHs/NBR复合母胶/溴化丁基橡胶并用胶的气体阻隔性能较好。;In this study，LDHs/NBR nanocomposites were prepared by latex co-coagulation method and the structure and properties of the nanocomposites were investigated.The results showed that，LDHs was uniformly dispersed in the NBR matrix.Compared with NBR compound，the physical properties and gas barrier property of LDHs/NBR nanocomposites were improved significantly.The co-coagulated LDHs/NBR masterbatch was blended with BIIR and the gas barrier property of the LDHs/NBR/BIIR blend was excellent when the blending ratio of LDHs/NBR was 1/20 and the total addition level of LDHs was 1 phr
