Description

TECHNICAL FIELD

[0001] The present application relates to a lignin-based anion-cation polymer dispersant and a preparation method of a sanding industrial oil stain hand washing liquid, which is mainly suitable for cleaning heavy oil stains on hands of workers engaged in machine repair, printing, machinery and other processing personnel, and belongs to the technical field of sanitary cleaning products. BACKGROUND

[0002] Hand washing is the best way to prevent hand-borne diseases. Hand washing liquid is a daily washing product for hand cleaning. Compared with traditional hand soap, it has the advantages of convenient use, avoidance of cross infection, diverse ingredients and functions, low cost, strong practicability and the like, and has become a daily consumer product. Workers engaged in machine repair, printing, machinery and other processing personnel often have heavy oil stains on their hands. Ordinary hand washing liquid and soap are difficult to clean. Using traditional cleaning methods including rubbing with sand and wood chips or using organic solvents to dissolve and remove hand oil stains can cause great safety hazards to workers' hands. Chinese patent application CN 109628241A discloses a heavy oil stain removing hand washing paste for machine repair, which is mainly composed of 1-5 parts of a surfactant, 10-15 parts of a soap solution, 0.5-3 parts of coconut oil, 0.4-0.8 parts of acid lactalbumin, 1-3 parts of sodium chloride, 2-3 parts of hydroxypropyl cellulose, 2-3 parts of hydroxymethyl chitosan, 30-50 parts of quartz sand, 1-5 parts of wood chips, 0.1-1.5 parts of essence and the like. The addition amount of 70-100 mesh quartz sand is too high, and wood chips are additionally added. The stability of the system is difficult to guarantee, and the sanding particles will settle over time. Chinese patent application CN 103860402A discloses an industrial heavy oil stain removing hand washing liquid with a bactericidal function. The addition amount of liquid paraffin is as high as 20%, and the addition amount of oleic acid is as high as 15%. Too much liquid paraffin will cause a certain irritation to hands, and oleic acid has a pork oil odor and is flammable. The mildness and safety need to be improved. Although the existing technology can clean heavy oil stains on hands, it still has the following problems. First, the stability of the sanding particles is poor, and the cleaning effect is not ideal due to easy settlement. Second, the emulsion system used has strong skin irritation, and the product has poor use feeling. Therefore, in order to solve the above technical problems, it is urgent to develop an industrial oil stain hand washing liquid with strong dispersibility, mild performance and strong stain removing capacity by adding a lignin-based anion-cation dispersant.
