摘要
磺酸铵与氢氧化钡反应制备石油磺酸钡防锈剂的工艺,可避免直接中和法和复分解法的缺点,易于大规模生产,环境污染很小;该工艺产品的钡含量13.9%,有效组分62.7%,与Texaco公司的TLA-107相当,同时具有良好的油溶性,60℃可溶于矿物油中,降低了防锈油的调和难度。通过对产品结构分析和盐雾性能评价试验,碱性磺酸钡有更好防锈性能,原因是胶体胶束结构中存在氢氧化钡,磺酸钡生成会更完全,残存的亲水性一价磺酸盐少,在金属表面形成的吸附膜强度更高。
The technology of preparing barium petroleum sulfonate antirust additive by the reaction of ammonium sulphonate and barium hydroxide, can overcome shortcomings of direct neutralization method and double decomposition method, which can be produced in large and has less environment pollution. The barium content and effective component content of the obtained product account for 13.9% and 62.7% respectively, which is equal to those of Texaco Company TLA - 107. In addition, the product is soluble in mineral oil at 60 ℃, so the blending difficulty of antirust oil can be reduced. Based on structure analysis and salt spray test evaluation, alkaline barium petroleum sulfonate has better antirust performance. It is because that when barium hydroxide exists in micellar colloid structure, barium petroleum sulfonate generated is more fully, residual hydrophilic monobasic sulfonate is less, those lead the strength of adsorption film formed on the metal surface to higher.
