摘要:
为了提高超高分子量聚乙烯的耐热性能，采用高岭土、碳酸钙两种材料作为填料进行耐热改性研究.通过实验，对复合材料的各种性能进行测试和分析，比较不同质量分数的填料对超高分子量聚乙烯各性能的影响.结论表明:高岭土和碳酸钙的填充明显改善了超高分子量聚乙烯的耐热性能，当填料质量分数为30%时，填充高岭土得到的复合材料的维卡软化温度为113 ℃，填充碳酸钙得到的复合材料的维卡软化温度为111 ℃，均提高30 ℃左右.其力学性能有不同程度的降低，当填料质量分数为10%时，复合材料的力学性能最好,之后随着添加比例的增大，其力学性能减小的速度也增加.综合考虑，填料质量分数在10%到20%之间时，能同时满足力学性能和耐热性能的需要.
Abstract:
Ultra high molecular weight polyethylene was modified by kaoline and calcium carbonate to improve its heat resistance.Various properties of the mixtures were tested and analyzed by experiment.The changes generated by different mass fraction of fillers were compared.The results show that kaolin and calcium carbonate can obviously improve the heat resistance of ultra high molecular weight polyethylene.When the filler mass fraction is 30%,the vicat softening temperature of the mixtures filled with kaolin is 113 ℃,and the vicat softening temperature of the mixtures filled with calcium carbonate is 111 ℃,both of them increasing about 30 ℃.The mechanical properties are reduced in some extent.The mechanical properties of the mixtures are best when the filler mass fraction is 10%,then they decrease with the increasing proportion of fillers.In a word,it can satisfy the requirement of mechanical properties and heat resistance when the filler mass fraction is between 10% and 20%.
