改性玄武岩纤维/天然橡胶复合材料的制备及性能研究

Preparation and property of modified basalt fiber/natural rubber composite

玄武岩纤维具有优秀的稳定性,良好的力学性能,以及环保和廉价等特点。采用冰醋酸对玄武岩纤维进行改性,并制得改性玄武岩纤维/天然橡胶复合材料。探讨了改性玄武岩纤维用量对橡胶复合材料的力学性能、热稳定性能的影响。结果表明:虽然添加改性玄武岩纤维降低了橡胶复合材料的力学性能,但可以有效降低橡胶复合材料的损耗因子;添加改性玄武岩纤维有利于提高橡胶复合材料的热稳定性;添加6份改性玄武岩纤维条件下纤维分布最理想,改性玄武岩纤维/天然橡胶复合材料的综合性能最优,130℃的损耗因子为0.029。

Basalt fiber has excellent stability,good mechanical properties,and environmental protection and cheap features.Basalt fiber modified by glacial acetic acid was used to prepare modified basalt fiber/natural rubber composites.The effects of modified basalt fiber content on the mechanical properties and thermal stability of composites were studied.Results showed that modified basalt fiber can reduce the loss factor of rubber composite effectively while reduced the mechanical properties.The addition of modified basalt fiber was beneficial to improve the thermal stability of composites.Fiber distribution was ideal and the comprehensive performance of composites was the best when 6 parts modified basalt fiber were added.The loss factor at 130℃ was 0.029.
