Oxalic acid complexing agent and application thereof
The invention belongs to the technical field of stone recovery, and particularly relates to an oxalic acid complexing agent and application thereof, and the oxalic acid complexing agent comprises the following raw materials: oxalic acid, aluminum chloride, ferric chloride, lauryl sodium sulfate and azodiisobutyronitrile. The oxalic acid complexing agent is used for treating the building recycled stones, so that the performance of the building recycled stones can be effectively improved, the mixing amount of the building recycled stones in concrete and the application range of the building recycled stones in engineering are improved, and dependence on natural stones is reduced. As a solid-liquid building recycled stone strengthening method, the oxalic acid complexing agent strengthening method can fully permeate a mortar layer on the surface of the building recycled stone, so that the performance of the building recycled stone is effectively improved. Compared with a traditional method for acid treatment of building recycled stones, the method has the advantages that through the synergistic effect of multiple effective components, surface mortar can be corroded more efficiently, a thin surface mortar layer can be removed more efficiently, a thick mortar layer can be sufficiently embrittled, most of the mortar layer is dissolved and falls off in the stirring process, and damage to the building recycled stones is small.
本发明属于石料回收技术领域，具体涉及一种草酸复合剂及其应用，所述草酸复合剂的原料组成包括：草酸、氯化铝、氯化铁、十二烷基硫酸钠、偶氮二异丁腈。本发明使用草酸复合剂处理建筑回收石料可以有效提高建筑回收石料性能，提高建筑回收石料在混凝土中的掺量和在工程中的应用范围，减少对天然石料的依赖。草酸复合剂强化法作为一种固‑液建筑回收石料强化方法，能够充分渗透建筑回收石料表面砂浆层，从而有效提高建筑回收石料的性能。相比于传统的酸处理建筑回收石料方法，该方法通过多种有效成分协同作用，能更高效腐蚀表面砂浆，清除较薄表面砂浆层，使较厚砂浆层充分脆化，在搅拌中大部分溶解和脱落，且对于建筑回收石料本身损伤较小。
