[0006] Chinese patent application CN101735892A discloses a composition containing MES for washing powder production, which is mixed in a mixer by soda ash, MES, aqueous solution, etc., but this highly alkaline water system will cause a large amount of MES to be hydrolyzed into Disodium salt affects product performance. In addition, the wet MES-containing composition is prepared into particles through a swing granulator. The solubility of the particles is seriously questionable.
Chinese patent application CN102277238A discloses a granular MES-containing composition. This method utilizes an extrusion granulation process, and the extrusion granulation particles have higher density and poor solubility, especially at low temperature.
Chinese patent application CN101955855A discloses a spherical detergent composition and a manufacturing method thereof. The method utilizes a wet mixture to be extruded into thin strips through an extruder, and then granulated into spherical particles by a spheronizer. Due to the addition of disintegrants in the composition, it can be quickly dissolved in water, but its product stability is questionable. Due to the addition of disintegrants, the product stability will be poor, and the particles will become fine powder or agglomerate
Chinese patent application CN102994258A discloses a preparation method of a detergent composition containing MES. In this method, a nonionic surfactant is sprayed on the powdered MES by spraying, and a layer of nonionic membrane coating is formed on the surface of the MES. , compared with powdered MES, the fluidity of the composition has been improved to some extent, but the fluidity is still poor. In addition, non-ionic surfactants are easy to form gels, which leads to poor solubility of the composition in water, so it dissolves in water Moreover, the performance of the composition prepared in the drum mixer by spraying is seriously questionable, such as its anti-caking property, particle size distribution, particle compressive strength, etc.
[0007] In addition, zeolite is added to the above MES composition as a filler. Zeolite has a unique pore structure, and there are many cavities in the middle of the interior. When the MES composition dissolves, water easily enters the cavity of the zeolite, which can accelerate the dissolution of MES. However, as a The filler will increase the difficulty and cost of granulating the MES composition, and the zeolite is insoluble in water, which will bring new insoluble zeolite residues

Abstract

The invention provides fatty acid methyl ester sulfonate (MES) composition particles for producing washing powder and a preparation method thereof. The MES composition particle contains 20-65 parts bymass of sodium fatty acid methyl ester sulfonate, 10-35 parts by mass of sodium carbonate, 0.05-5 parts by mass of sodium carboxymethyl cellulose, 5-65 parts by mass of sodium sulfate, 0.1-10 parts by mass of a polymer, and 0-15 parts by mass of sodium silicate. The invention solves the problems that MES is hydrolyzed in a high-temperature and strong-alkaline system in the production process of the washing powder, the MES is poor in stability, large in irritation, easy to decompose and agglomerate, low in dissolving speed at low temperature and low in MES content in the washing powder in theusing process.

Description

technical field [0001] The invention relates to the field of household chemicals, in particular to a MES composition particle used for producing detergent. Background technique [0002] Fatty acid methyl ester sodium sulfonate (MES) is an anionic surfactant with excellent performance prepared from natural renewable resources such as coconut oil and palm oil. It has the advantages of safety, non-toxicity, strong resistance to hard water, and complete biodegradability. Known as a truly environmentally friendly green surfactant, compared with currently used petroleum-based surfactants (such as sodium dodecylbenzenesulfonate, sodium α-alkenylsulfonate, etc.), it has considerable advantages in performance, It is of great significance to solve the common problem of long-term dependence on petroleum in the daily chemical industry, so MES has gradually become a hot spot in the field of detergent research at home and abroad. [0003] However, MES is not resistant to strong alkali, a...
