摘要

摘要: 用磷酸、硅烷KH550和鋼渣制備改性多孔鋼渣, 以改性多孔鋼渣取代部分炭黑.利用改性多孔鋼渣、炭黑、橡膠、促進劑、硫磺、硬脂酸和氧化鋅進行復合, 制備一系列改性多孔鋼渣/橡膠復合材料, 研究了磷酸/鋼渣質量比、硅烷KH550/多孔鋼渣質量比、促進劑/硫磺質量比、硬脂酸/氧化鋅質量比和改性多孔鋼渣/炭黑質量比對改性多孔鋼渣/橡膠復合材料力學性能的影響, 并且分析其影響機理.結果表明, 當磷酸用量為1.2 g、鋼渣用量為30 g、硅烷KH550用量為0.3 g、炭黑用量為20 g、促進劑用量為0.8 g、硫磺用量為1.2 g、硬脂酸用量為0.8 g、氧化鋅用量為2.2 g和橡膠用量為100 g時, 改性多孔鋼渣/橡膠復合材料的力學性能較好, 即拉伸強度為18.4 MPa、邵爾A硬度為68.8、撕裂強度為44.6 kN·m^-1.磷酸與硅烷KH550可以改善鋼渣的孔結構與表面結構; 適量的促進劑/硫磺質量比與硬脂酸/氧化鋅質量比可以消除硫磺形成的內硫環, 促使橡膠交聯鍵穩定.改性多孔鋼渣與橡膠以物理方式進行復合形成良好的包裹結構.

Abstract: High value-added utilization of solid wastes, such as the development of an inexpensive inorganic rubber filler, is one of the important approaches of sustainable development. Phosphoric acid, silane KH550, and steel slag were innovatively used to prepare modified porous steel slag, which partially replaced carbon black in this study. Modified porous steel slag was combined with carbon black, rubber, accelerator, sulfur, stearic acid, and zinc oxide to prepare a series of modified porous steel slag/rubber composite materials. This study investigated the mass ratios of phosphoric acid/steel slag, silane KH550/porous steel slag, accelerator/sulfur, and stearic acid/zinc oxide and the effect of the mass ratio of modified porous steel slag/carbon black on the mechanical properties of the prepared modified porous steel slag/rubber composite materials. At the same time, the influence mechanism was analyzed. The results indicate that the modified porous steel slag/rubber composites (the amounts of phosphoric acid, steel slag, silane KH550, carbon black, accelerator, sulfur, stearic acid, zinc oxide, and rubber are 1.2, 30, 0.3, 20, 0.8, 1.2, 0.8, 2.2, and 100 g, respectively) have good mechanical properties, with the tensile strength of 18.4 MPa, Shore A hardness of 68.8, and tearing strength of 44.6 kN·m^-1. Phosphoric acid and silane KH550 can improve the pore and surface structures of steel slag. Appropriate ratios of accelerator/sulfur and stearic acid/zinc oxide can destroy the internal sulfur ring, which stabilizes the cross bond of rubber. Thus, a desirable package structure can be obtained by physically combining modified porous steel slag with rubber.
