Self-dispersing composite conductive filler for road self-sensing and preparation method of self-dispersing composite conductive filler
The invention relates to a self-dispersing composite conductive filler for road self-sensing and a preparation method of the self-dispersing composite conductive filler. The self-dispersed composite conductive filler is prepared by uniformly loading a zero-dimensional conductive filler on a two-dimensional conductive filler and/or a one-dimensional conductive filler with anionic surfactant molecules, wherein the mass of the two-dimensional conductive filler and/or the one-dimensional conductive filler with the anionic surfactant molecules accounts for 40wt%-50wt% of the mass of the self-dispersing conductive filler, and the mass of the zero-dimensional conductive filler accounts for 50wt%-60wt% of the mass of the self-dispersing conductive filler. The invention also provides a preparation method of the dispersed composite conductive filler. When the self-dispersing conductive filler provided by the invention is added into a cement-based material, not only can the fiber bridging effect of the one-dimensional conductive filler or the multi-layer structure toughening effect of the two-dimensional conductive filler be played, the mechanical property of the cement-based material be enhanced, but also the hydration degree of cement can be further improved due to the nano-nucleation effect of the zero-dimensional conductive filler particles, so that the self-dispersing conductive filler can be applied to the cement-based material. The mechanical property of the cement-based smart material is enhanced.
本发明涉及一种用于道路自感知的自分散复合导电填料及其制备方法。所述自分散复合导电填料是将零维导电填料均匀负载在带有阴离子表面活性剂分子的二维导电填料和/或一维导电填料上；其中，带有阴离子表面活性剂分子的二维导电填料和/或一维导电填料占自分散导电填料质量的40wt％～50wt％，零维导电填料占自分散导电填料质量的50wt％～60wt％。本发明还提供了该分散复合导电填料的制备方法。本发明提供的自分散导电填料加入水泥基材料中时，不仅可以发挥一维导电填料的纤维桥接作用或二维导电填料的多层结构增韧作用，增强水泥基材料的力学性能，零维导电填料颗粒的纳米成核效应还能够进一步提高水泥水化程度，增强水泥基机敏材料的力学性能。
