Problems solved by technology

However, 85% of the MES used in this invention is solid, which is easy to agglomerate during warehouse storage or transportation, and is difficult to crush, which seriously affects the use of MES
In addition, solid MES is easy to produce irritating dust during processing, and a large amount of use in the workshop will cause harm to the health of workers
In addition, the composition is made by extrusion granulation, which has high density and poor solubility, especially at low temperature.

Embodiment 1

[0026] 40kg diatomite, 15kg precipitated silica, 3kg4A zeolite (Gantz whiteness 96%, apparent density 0.3g / cm 3 ), 25kg of cross-linked starch are added to the high-speed mixer with a stirring speed of 150rpm and stirred for 8min. The percentage content is 30%) was added therein for wet granulation, and then 12.5 kg of 4A zeolite was added and mixed for 3 minutes for wet granulation. The final granules obtained by two-step wet granulation are dried in a fluidized bed at 120° C. for 15 minutes, and finally sieved through a 18-80 mesh sieve to obtain granules containing sodium fatty acid methyl ester sulfonate.

[0027]The sodium fatty acid methyl ester sulfonate particle obtained above is checked, and the results are as shown in table 1 and table 2, and its active substance sodium fatty acid methyl ester sulfonate content is 65.00%, moisture content 5.00%, undissolved matter is lower, The particle size distribution is uniform. Therefore, the high activity sodium fatty acid me...

Embodiment 2

[0029] 40kg fumed silicon dioxide, 74kg natural zeolite, 20kg carboxymethyl starch, 15kg bentonite are added to a high-speed mixer with a stirring speed of 100rpm and stirred for 7min. The mass percent content of sodium ester sulfonate is 70%, and the mass percent content of water is 30%) is added thereinto for wet granulation. Then add 26kg of 4A zeolite and continue mixing for 3 minutes for wet granulation. The final granules obtained by two-step wet granulation are dried for 30 minutes in a fluidized bed at 90° C., and finally sieved through a 18-80 mesh sieve to obtain granules containing sodium fatty acid methyl ester sulfonate.

[0030] The particles obtained above were inspected, and the results are shown in Table 1 and Table 2. The active substance content was 55.00%, the moisture content was 3.40%, the undissolved matter was relatively low, and the particle size distribution was uniform. Therefore, the active substance content in the high active particles obtained by...

Embodiment 3

[0032] With 25kg white carbon black, 55kg4A zeolite (Gantz whiteness 96%, apparent density 0.3g / cm 3 ), 10kg oxidized starch, 90kg bentonite are added to the high-speed mixer that stirring speed is 100rpm and stir 7min, after mixing uniformly, 275kg paste sodium fatty acid methyl ester sulfonate (mass percentage content 70% of fatty acid methyl ester sodium sulfonate, The mass percent content of water is 30%) was added therein for wet granulation, and then 45kg of 4A zeolite was added and mixed for 3 minutes for wet granulation. The final granules obtained by two-step wet granulation in a fluidized bed at 100°C are dried for 30 minutes, and finally sieved through a 18-80 mesh sieve to obtain granules containing sodium fatty acid methyl ester sulfonate.

[0033] The particles obtained above were inspected, and the results are shown in Table 1 and Table 2. The active substance content was 45.02%, the moisture content was 2.80%, the undissolved matter was relatively low, and the ...

Abstract

The invention discloses particles containing sodium fatty acid methyl ester sulfonate and a preparation method thereof. The preparation method comprises the following steps: mixing a wrapper and 20-75 parts by weight of paste sodium fatty acid methyl ester sulfonate, granulating by a wet process, drying, and screening. The wrapper is a composition comprising the following components in parts by weight: 1-40 parts of zeolite, 1-40 parts of silicate, 1-30 parts of modified starch and 0-30 parts of bentonite. The mass percent of the sodium fatty acid methyl ester sulfonate in the particles containing sodium fatty acid methyl ester sulfonate can be up to 65%; the particles containing sodium fatty acid methyl ester sulfonate can be used as a raw material for preparing washing powder or directly used as a detergent; and the invention effectively solves the problems of poor stability, high decomposition tendency, high lumping tendency, poor low-temperature solubility and the like in the use process of sodium fatty acid methyl ester sulfonate.

Description

technical field [0001] The application relates to the field of daily chemicals, more specifically, the application relates to a particle containing sodium fatty acid methyl ester sulfonate and a preparation method thereof. Background technique [0002] In recent years, with the national requirements for energy conservation and emission reduction, the development of green economy, and people's increasing awareness of environmental protection, detergents containing green and environmentally friendly raw materials have become more and more popular among consumers and society. Sodium fatty acid methyl ester sulfonate is a green surfactant with excellent performance obtained from natural renewable resources such as coconut oil and palm oil through transesterification, sulfonation and neutralization. It has a wide range of sources, natural Renewable, safe and non-toxic, strong resistance to hard water, excellent decontamination in cold and warm water, and easy biodegradation of wa...
