安全高效冷烫剂的研制

Preparation of safe and high effective cold waving

将特定的高分子化合物DBP(聚乙烯醇)溶解在冰醋酸水溶液中,通入H2S气体1min,再加入少量Ba(OH)2溶液,过滤,调节pH=7后,向滤液中加入一定量的硅油和羧甲基纤维素钠(CMC),混匀得到高分子活性助剂。将此助剂质量分数0 5%～1 0%加入到含L-半胱氨酸质量分数为4 4%～5 6%的还原剂中,复配其他助剂制得安全无毒、高效且成本较低的通用冷烫剂。

The subject was prepared with 44 %～56 % L-cysteine and 05 %～10 % active polymer assistant.First,quantitative poval was added into ethylic aqueous solution.Second,hydrothion was passed through it for 1 min.Third,some hydroxide was added in and then filtered,the pH of its filtrate was ajusted to 7,a little siloxane polymer and carboxymethyl cellulose as well as other supplementary compositions were mixed in. Then the safe and high effective cold waving was prepared.
