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.
