preparation example Construction

[0011] The invention provides a kind of preparation method of oxygen-containing detergent, comprises the following steps:

[0012] A, will contain the surfactant of 1-10 weight part, 10-70 weight part sodium carbonate, 1-40 weight part sodium sulfate, contain or do not contain the raw material composition of additional auxiliary agent in the reactor; Said additional The auxiliary agent contains 0-20 parts by weight of sodium bicarbonate, 0-30 parts by weight of sodium salt of silicic acid and 0-10 parts by weight of anti-dirt redeposition agent;

[0013] B. Add aqueous hydrogen peroxide solution to the reactor, control the reaction temperature in the reactor to 0-60°C, and mold and dry the product after the reaction is completed to obtain 100 parts by weight of active oxygen containing 1-12.33% oxygen detergent.

[0014] In the present invention, the surfactant is various surfactants commonly used in household detergents in the prior art, such as one or more selected from ani...

Embodiment 1

[0041] Add 70.0kg of light sodium carbonate, 1.0kg of sodium stearate and 1.0kg of anhydrous sodium sulfate into the reactor and stir for 5 minutes. Weigh 53.26kg of hydrogen peroxide aqueous solution (in the form of H 2 o 2 50.2wt% in total), add the aqueous hydrogen peroxide solution into the reactor through the spray pipe within 90 minutes, and control the reaction temperature at 0-5°C; after the addition of the aqueous hydrogen peroxide solution, continue the reaction for 10 minutes. The reaction product was granulated by a granulator, and then dried in a fluidized bed to obtain solid particles, namely the oxygen-containing detergent S1 of this embodiment, which was used as a detergent and disinfectant.

Embodiment 2

[0043] 50.0kg sodium carbonate monohydrate (on a dry basis), 4.0kg sodium dodecylbenzenesulfonate (LAS), 1.0kg fatty alcohol polyoxyethylene ether (AEO), 1.0kg alpha-olefin sulfonate sodium (AOS ), 5.0kg sodium metasilicate pentahydrate (on a dry basis), 8.0kg sodium carboxymethylcellulose (CMC), 13.0kg food grade sodium bicarbonate and 14.4kg sodium sulfate decahydrate (on a dry basis) In the reactor, stir for 5 minutes. Weigh 3.09kg of hydrogen peroxide aqueous solution (in the form of H 2 o 2 70.3wt% in total), add the aqueous hydrogen peroxide solution into the reactor through the sprayer within 30 minutes, and control the reaction temperature at 20-25°C; after the aqueous hydrogen peroxide solution is added, continue the reaction for 10 minutes. The reaction product is granulated by a granulator, and then dried in a fluidized bed to obtain solid particles. Then add 0.5 kg of amylase and 0.02 kg of lemon essence to the solid granules to obtain the oxygen-containing dete...

Abstract

The invention provides a preparation method of an oxygen-containing washing agent. The preparation method comprises the following steps of: A, adding 1-10 parts by weight of surfactant, 10-70 parts by weight of sodium carbonate, 1-40 parts by weight of sodium sulfate and a raw material combination containing or not containing additional assistant into a reactor, wherein the additional assistant contains 0-20 parts by weight of sodium bicarbonate, 0-30 parts by weight of silicious sodium salt and 0-10 parts by weight of an anti-dirt redeposition agent; and B, adding an aqueous hydrogen peroxide solution in the reactor, controlling the reaction temperature of the reactor to be 0-60 DEG C, shaping and drying after reaction to obtain 100 parts by weight of the oxygen-containing washing agent the active oxygen content of which is 1-12.33%. The invention also provides the oxygen-containing washing agent prepared by using the preparation method. The preparation method provided by the invention is safe and environment-friendly, and can prepare the oxygen-containing washing agent which has the advantages of uniform component distribution, variable active oxygen content, stable performance,and excellent washing effect.

Description

technical field [0001] The invention relates to the field of detergents in daily chemicals, in particular to a preparation method of an oxygen-containing detergent and an oxygen-containing detergent prepared by the preparation method. Background technique [0002] Detergent is an essential daily chemical in daily life. For colored stains on natural plants or food, bleaching agents that can release active oxygen are usually used. At present, the two commonly used bleaching agents are sodium perborate and sodium percarbonate, which can release active oxygen after dissolving in water, so that they can be removed by oxidation. Various pigments that are stained by clothing or self-yellowing. Sodium perborate can fully exert its oxygen-release bleaching performance when the water temperature is above 60°C, and it needs to be used with an activator or metal catalyst at low temperature; at the same time, sodium perborate has potential health hazards and environmental hazards. The ...
