毕业设计说明书（论文）中文摘要针对目前工业上使用的水溶性防锈剂存在的不足，制备几种有机羧酸醇铵盐，经泡沫试验，考查了烷基链长和羧基数目对泡沫性能的影响。经防锈性能试验，研究了pH值、碳链长度、羧基个数和醇胺所占比例对其防锈性能的影响。并将有机羧酸醇铵盐制成了性能较好的金属清洗剂和液压液。然后，以甲苯为溶剂，在反应温度110℃，原料摩尔比n（硼酸）：n（乙醇胺）为1：4的条件下合成硼酸三乙醇胺酯；原料摩尔比n（硼酸）： n（三乙醇胺）为1：1的条件下合成硼酸氨基三乙酯，经防锈性能测试，表明硼酸三乙醇胺酯和硼酸氨基三乙酯都具有较好的防锈能力。最后，在氮气的保护下，原料摩尔比n（油酸）：n（顺酐）：n（二乙醇胺）为1：1：3，经催化合成油酸酰胺型防锈剂，经防锈性能测试，防锈时间长达15。6h，表明油酸酰胺型防锈剂具有优良的防锈性能。78579

Title  The Study on Preparation and Properties of New Water-soluble Rust Inhibitors

Abstract Aiming at the deficiency of water-soluble rust inhibitors in industry at present, some organic carboxylic acid alcohol ammonium salts were prepared。 The effects of the alkyl chain length and the carboxyl number on foam capacity were tested by foam experiment。 The effects of pH value, the carbon chain length, carboxyl number and the proportion of the alcohol amine on the rust-inhibiting performance were studied by rust-inhibiting performance testing。 The good capability metal cleaner and the hydraulic fluidwere made of organic carboxylic acid alcohol ammonium salts。 Then boric acid triethanolamine ester was synthesized in the condition that toluene was the solvent, the temperature was 110℃, raw material mole ratio isn (boric acid):n (triethanolamine) = 1:4; triethanolamine borate was synthesized under the condition that n (boric acid): n (triethanolamine) = 1:1。 Rust-inhibiting performance testing proved that both boric acid triethanolamine ester and triethanolamine borate had good rust-inhibiting capability。 At last, under the protection of the nitrogen and raw material mole ratio is n (oleic acid): n (maleic anhydride): n (diethanolamine) = 1:1:3, oleamide rust inhibitors was catalytic synthesized。 The rust-inhibiting time was up to 15。6 h, which was obtained by rust-inhibiting performance testing。 This showed that oleamide rust    inhibitors had an excellent rust-inhibiting performance。
