水基橡胶模具清洗剂的研发与配方优化《模具技术》2022年6期 刘明东 (上海喜赫精细化工有限公司，上海 201620） 摘 要：模具表面残留的污垢反复经过高温加热会被氧化，在模具表面形成难以清洗的固化膜、垢斑等，这就需要对模具进行定期的清洗，将模具表面残留的各种污垢清洗干净。为了获得一种环保的水基模具清洗剂，通过正交实验和单因素试验分析了几种原料对硅油、石蜡、矿物油、橡胶等污垢清洗效果的影响，最终确定了水基清洗剂的配方为：喜赫脂肪酸甲酯乙氧基化物FMEE 6%、喜赫羧乙基硫代丁二酸CETSA 5%、200#溶剂油3%、喜赫伯烷基磺酸钠PAS-80 4%、环已酮3%、喜赫脂肪酸甲酯二丙酸钠 6%、偏硅酸钠3%、氢氧化钠5%、三乙醇胺1%、六亚甲基四胺1%、杀菌剂0.5%、纯水62.5%。 关键词：模具清洗剂; 水基; 羧乙基硫代丁二酸; 环已酮 中图分类号： TQ330.1 文献标志码： A Development and Optimization of water-based rubber mold cleaner LIU Ming-dong (Shanghai Xihe Fine Chemical Co.,Ltd, Shanghai 201620,China) Abstract: The residual dirt on the mold surface will be oxidized in the high temperature heating process and the solidified film and dirt spots will be formed on the mold surface, which requires regular cleaning for the mold.In order to obtain an environment-friendly water-based mold cleaner, the influence of several raw materials on the cleaning effect of silicone oil, paraffin, mineral oil and rubber was analyzed by orthogonal test and single factor test, the formulation of the water-based detergent was determined as fatty acid methyl ester ethoxylated FMEE 6%, CETSA 5%, 200#solvent oil 3% , PAS-80 4%, cyclohexanone 3%, fatty acid methyl ester dipropionate sodium 6%, sodium metasilicate 3%, sodium hydroxide 5%, triethanolamine 1%, hexamethylenetetramine 1%, fungicide 0.5%, and pure water 62.5%.
