|
摘要
为了进一步提高橡胶材料的耐磨性,满足其在印刷领域的应用要求,本研究首先制备Si69改性GO/SiO_2复合填料,然后将复合填料填充到丁苯橡胶中制得Si69改性GO/SiO_2/SBR复合材料,并对复合填料和复合材料的结构与性能进行研究。结果表明:Si69改性GO/SiO_2复合填料在SBR基体中的分散性良好,可以提高橡胶复合材料的力学性能。并且随着改性GO和SiO_2在填料中比例的增加,橡胶复合材料的耐磨性能明显提高,损耗因子随之降低,说明Si69改性GO/SiO_2复合填料可以大大增加橡胶制品的使用寿命。
In order to further improve the abrasion resistance of rubber materials and meet their application requirements in printing field, Si69 modified graphene oxide(GO)/SiO_2 composite filler was prepared in this paper.Then Si69 modified GO/SiO_2/styrene-butadiene rubber(SBR)composites were prepared by filling composite fillers into SBR. The effects of Si69 modified GO/SiO_2 composite filler on structure and properties of SBR composites were investigated. The results showed that the dispersion of Si69 modified GO/SiO_2 composite filler in rubber matrix is good. The mechanical properties of rubber composites are improved. And with the increase of content of composite filler in filler system,abrasion resistance of composite is strengthened, and the loss factor is decreased. So the service life of rubber product can be prolonged by the addition of Si69 modified GO/SiO_2 composite filler.
