Problems solved by technology

[0003] However, the fluorescent whitening agent usually added in the detergent production process is powdery, and its solubility in water is very low. Slurry, then add to the batching tank of detergent
[0004] The above-mentioned addition method has problems such as dust pollution on the feeding site, or uneven mixing of the slurry, cumbersome operation, and difficulty in dissolving when added to the preparation kettle, which affects product quality.

preparation example Construction

[0030] A kind of preparation method of fluorescent whitening agent aqueous solution for detergent that the present invention proposes comprises the following steps:

[0031] 1) Add 100 parts by weight of process water at 30-50°C and 10-30 parts by weight of surfactant for detergent into the stirred tank in sequence, and start stirring;

[0032] 2) After the surfactant is completely dissolved, slowly add 5 to 15 parts by weight of powdery fluorescent whitening agent into the stirring tank and continue stirring, and keep stirring for 10 to 35 minutes until the solution system is homogeneous and transparent;

[0033] 3) After observing that the whitening agent solution is clear and transparent, pump the prepared whitening agent aqueous solution into the high-level storage tank, and add it into the detergent preparation tank according to the formula ratio to produce detergent products.

[0034] During the production process, one day's brightener solution can be prepared at one tim...

Embodiment 1

[0037] Add 1000kg of process soft water at 30°C to the stirring tank, start stirring; then add 80kg of coco alcohol polyoxyethylene ether (AEO9), 12.5kg of alkyl glucoside (APG), 20kg of sodium lauryl ether sulfate (AES), coconut Oleamidopropyl betaine 17.5kg kept stirring for 15 minutes; after the surfactant was completely dissolved, add 80kg of optical brightener (CBS), continue to stir for 25 minutes, the solution was slightly yellow, clear and transparent, stop stirring, beat Material spare.

Embodiment 2

[0039] Add 1000kg of process soft water at 35°C to the stirred tank, start stirring; then add 120kg of coco alcohol polyoxyethylene ether (AEO7) and 30kg of alkyl glycoside (APG) in sequence, and keep stirring for 12 minutes; after the surfactant is completely dissolved Add 100kg of fluorescent whitening agent (CBS) again, continue to stir for 20 minutes, the solution is light yellow and clear and transparent, stop stirring, beat the material for subsequent use.

Abstract

The invention discloses a preparation method of a fluorescent brightener water solution for a detergent. The preparation method comprises the steps that (1) process water and a detergent surfactant are sequentially added into a stirring kettle according to the weight, and stirring is started; and (2) when the surfactant is completely dissolved, a powdery fluorescent brightener is added into the stirring kettle, and stirring is continued until the solution is homogenous and transparent. According to the invention, the homogenous and transparent water solution is prepared with the solubilization effect of the surfactant to the fluorescent brightener. During a production process, the brightener solution for one day use can be prepared once and can be stored in a high-level storage tank. An addition amount can be controlled through a meter, such that production operation is convenient, production efficiency is improved, and product quality is stabilized.

Description

technical field [0001] The invention relates to a detergent, which belongs to the technical field of daily chemical products, and more specifically relates to a preparation process of an aqueous solution of a fluorescent whitening agent for detergent. Background technique [0002] With the continuous improvement of people's living standards in our country, the detergent industry has also developed rapidly, and people's functional requirements for detergents are also tending to be diversified. Fluorescent whitening agents, as a functional additive that can significantly improve washing performance, have been accepted Widely used in detergents. [0003] However, the fluorescent whitening agent usually added in the detergent production process is powdery, and its solubility in water is very low. Make it into a slurry, and then add it to the detergent batching kettle. [0004] The above-mentioned addition method has problems such as dust pollution at the feeding site, or uneve...
