Description

一种生物基多孔碳增强改性聚氨酯复合材料
技术领域
本发明涉及的是一种复合材料技术领域的方法，具体是一种生物基多孔碳增强改性聚氨酯复合材料。
背景技术
聚氨酯弹性体由于其软硬段比例的可调节性，可制备出不同性能和通途的聚氨酯材料，广泛应用于航空航天、航海船舶、医疗设备、厂矿机械等工程领域。聚氨酯弹性体软段决定材料柔性和韧性，硬段决定材料强度和刚性，但软硬段间存在明显的相分离，因此常规方法和配方制备的纯聚氨酯材料其刚性相对较低，导热及热稳定性差，摩擦系数低但磨损量较高，需要对其改性以满足工程使用要求。
发明内容
本发明目的是提供一种生物基多孔碳增强改性聚氨酯复合材料，生物质多孔碳材料取用天然竹子或竹笋为原料，制备工艺简单，可大规模工业化生产，制备得到的聚氨酯复合材料具有优异的拉伸性能、热稳定性和减摩耐磨特性。
为实现上述技术目的，本发明是通过以下技术方案实现的：
一种生物基多孔碳增强改性聚氨酯复合材料，其特征在于：按重量份数计，包括30～40份聚丙二醇，28～36份异佛尔酮二异氰酸酯，18～22份3,3'-二氯-4,4'-二氨基二苯基甲烷，1～20份生物基多孔碳，3～10偶联剂。
所述的一种生物基多孔碳增强改性聚氨酯复合材料，其特征在于所述的聚丙二醇分子量为200～10000。
所述的一种生物基多孔碳增强改性聚氨酯复合材料，其特征在于所述的生物基多孔碳为竹炭、竹笋碳的一种或两种，碳材料的比表面积为100～3000m2/g。
所述的一种生物基多孔碳增强改性聚氨酯复合材料，其特征在于所述的偶联剂为乙烯基三氯硅烷、乙烯基三乙氧基硅烷、γ-氯丙基三氯硅烷，γ-氯丙基三乙氧基硅烷、γ-氨丙基三乙氧基硅烷、γ-(2,3-环氧丙氧)丙基三甲氧基硅烷中的一种或两种。
将已脱水处理的聚丙二醇与生物基多孔碳800转/min机械搅拌10分钟，加入异佛尔酮二异氰酸酯，100～110℃反应3-6小时，依次加入偶联剂、3,3'-二氯-4,4'-二氨基二苯基甲烷搅拌10～30秒后加压硫化，脱模即得生物基多孔碳增强改性的聚氨酯复合材料。
本发明与现有技术相比具有如下的有益效果：生物基多孔碳原料为天然竹子或竹笋，加工工艺简单，所得多孔碳材料比表面积为600～3000m2/g。填充改性制备聚氨酯复合材料，基体树脂在多孔碳中形成网状交联结构，多孔碳相当于铆钉牢牢镶嵌在基体树脂中，起到缓冲和分散应力作用，成功制备的聚氨酯复合材料具有优异的力学性能、热性能和减摩耐磨性能。生物基多孔碳材料的填充质量百分含量为3％时，复合材料材料的拉伸强度提高到125％，断裂伸长率提高到454.01％，生物基多孔碳材料在聚氨酯基体中分散均匀，有效起到增韧增强效果；热失重分析结果显示，复合材料起始热分解温度提高15℃；25N载荷，对摩擦副为45#钢，表面粗糙度Ra为0.16μm；表面硬度为HRC50-55下，复合材料摩擦系数由1.58降低到1.19，磨损量由0.178降低到0.068。本发明得到了高性能复合材料，具有高的工业应用前景。
