Problems solved by technology

Commercially available flake or powder products generally have the problems of easy caking and insoluble, and are difficult to be directly used in the production of washing powder
In the traditional washing powder production process, if the commercially available MES product is directly applied in the pre-batching process, the MES product is easily decomposed to form disodium salt after being dried at high temperature in the alkaline washing powder slurry, which will affect the removal process. Pollution performance; if the commercially available MES products are directly applied to the post-batching process, the powder or flake MES products are easy to agglomerate and difficult to mix evenly with other components in washing powder depending on the difference in specific gravity, and their low temperature solubility is poor , seriously affecting its application in civilian laundry detergent

Abstract

The invention discloses a granular fatty acid methyl ester sulfonate (MES)-containing composite. A method for preparing the granular MES-containing composite comprises the following steps of: mixing the following raw materials including 40 to 90 mass parts of MES, 5 to 60 mass parts of anhydrous sodium sulphate, 0 to 30 mass parts of 4A zeolite, 2 to 20 mass parts of sodium carboxymethyl starch and 0 to 10 mass parts of bentonite uniformly, extruding and granulating under the condition of external protective wind, cooling by dried air at the temperature of between 5 and 30 DEG C to be hardened completely to obtain granules, and sieving by a 10 to 40-mesh screen. The granular MES-containing composite has the characteristics of high content of active matter MES and flowability and small influence on environment, is easy to dissolve, and can be used as the raw materials in many downstream processes.

Description

technical field [0001] The invention relates to a granular surfactant, especially a granular composition containing fatty acid methyl ester sulfonate (MES). Background technique [0002] With the continuous consumption of crude oil resources and the oil price fluctuations caused by the turmoil in the international situation, people are paying more and more attention to resources other than oil, and fatty acid methyl ester sulfonate (MES) is a kind of anionic surface produced from natural oils and fats. active agent. Its excellent performance, such as: decontamination ability under phosphorus-free state, hard water resistance, biodegradation, low toxicity, low irritation, etc., has been familiar to people as early as 20 years ago, and it has become a surface active agent in recent years. focus of research in the pharmaceutical field. [0003] However, in addition to block products, MES products currently on the market also have flake or powder products. Commercially availa...
