Steel fiber surface modification treatment method
The invention belongs to the technical field of buildings, and discloses a steel fiber surface modification treatment method which comprises the following specific steps: step 1, dissolving dopamine (DA) in a tris (hydroxymethyl) aminomethane (Tris) buffer solution, and fully stirring to obtain a DA solution with specific concentration for later use; step 2, soaking a certain mass of steel fibers in a DA solution for a specific time; 3, taking out the soaked steel fibers, and cleaning the steel fibers with clear water; and 4, drying the cleaned steel fibers to constant weight, and cooling to room temperature for later use. According to the treatment method, DA can be effectively subjected to self-polymerization to generate PDA, PDA is attached to the surface of the steel fiber to change the surface property of the material, modify the surface roughness of the steel fiber and improve the hydrophilicity, the strength and durability of the concrete can also be remarkably enhanced, and the treatment method has the advantages of prolonging the service life of the concrete, reducing the cost and the like. And the maintenance cost of the service life cycle of the concrete structure is reduced.
本发明属于建筑技术领域，本发明公开一种钢纤维表面改性处理的方法，具体步骤为：步骤一：将多巴胺(DA)溶解在三羟甲基氨基甲烷(Tris)缓冲液中，并充分搅拌，得到特定浓度的DA溶液备用；步骤二：将一定质量钢纤维置于DA溶液浸泡特定时间；步骤三：取出浸泡处理完成的钢纤维，使用清水进行清洗；步骤四：清洗完成后的钢纤维烘干至恒重，冷却至室温后备用。本发明通过该处理方法可以有效的将DA自聚合生成聚多巴胺(PDA)，PDA附着在钢纤维表面来改变材料表面性质，改性钢纤维表面粗糙度和提高亲水性，还能显著增强混凝土强度和耐久性，对延长混凝土的使用寿命，降低混凝土结构寿命周期维护成本具有十分积极的作用。
