preparation example Construction

[0071] The preparation method of the random copolymer containing zwitterionic groups is: monomer A, monomer B, monomer C and initiator (azobisisobutyronitrile, a kind of dimethyl azobisisobutyrate or more, the weight is 0.5-2.5% of the total weight of the monomer) are dissolved in methanol successively, heated to 50-80°C, and carried out under the condition of the presence of protective gas (one of nitrogen, argon, and helium) The radical polymerization reaction lasts for 4-24 hours. After the reaction, the reaction system is placed in a dialysis bag, dialyzed in deionized water, and freeze-dried to obtain a random copolymer.

Abstract

The invention relates to the field of a daily chemical detergent and discloses an environmentally-friendly laundry soap powder composition and a preparation method thereof. The environmentally-friendly laundry soap powder composition contains sodium aliphatate activated particles; and the sodium aliphatate activated particles comprise components in percentage by mass as follows: 50 to 99% of sodium aliphatate in which the ratio of 12C to 18C is over 90wt%, 0.1 to 10% of surfactant and 0 to 5% of assistant. The invention can solve a problem of tail gas pollution which is brought in by soap powder production and caused by front addition of the sodium aliphatate; and meanwhile, the invention also can solve problems of poor solubility and more floating powder of soap powder, difficulty in blanking for workshop production and unstable quality which are brought in by after addition of the sodium aliphatate. Moreover, the detergency of the product is effectively promoted, and comprehensive performance is better.

Description

technical field [0001] The invention relates to the field of daily chemical detergents, in particular to an environment-friendly laundry soap powder composition and a preparation method thereof. Background technique [0002] The main surfactant in ordinary washing powder is petroleum-based surfactant, while the main surfactant in laundry soap powder formula is sodium fatty acid (commonly known as soap base). The soap powder standard (QB / T 2387) stipulates that the dry sodium soap content is greater than or equal to 7%. [0003] It has been reported in the prior art that solid fatty acid sodium is added after soap powder without high temperature drying, but the solubility of soap powder produced by this process is not good, there is residue on the clothes after washing, and fatty acid sodium is easy to stick to the warehouse and difficult to discharge , affecting product quality. [0004] In view of the deficiencies of the post-mixing and adding process of the above-mention...
