Embodiment 1

[0029] Please see attached Figure 1-2 , Preparation of PEPK-AM copolymer surfactant PM: Weigh 9g of acrylamide and pour it into an iodine flask filled with 100mL of ultrapure water, and stir evenly. Add 0.2g of sodium persulfate, 0.1g of sodium sulfite, and 9g of PEPK into the iodine flask in sequence, and stir evenly. Protect the reaction system with nitrogen gas and seal the bottle cap. After constant temperature stirring at 37°C for about 24 hours, a colorless viscous polymer solution was obtained. After adding about 100mL of absolute ethanol to the polymerization solution, a white sticky substance was precipitated. After filtering and shearing and drying, a porous white to light yellow block solid PEPK-AM copolymer was obtained, with a net weight of 16.75g (93% yield) . Take a small amount (10 mg) of the copolymer and add (1 L) deionized water and stir until the gel-like polymer is completely dissolved into a colorless and odorless clear liquid, which is the surfactant...

Embodiment 2

[0031] PM as LCD screen cleaner: Spray PM liquid directly on the surface of the LCD screen, the droplets are easy to adhere to the screen, and the dust and other stains can be removed by gently drying with a paper towel, and there is no trace of foam or other residues on the cleaned screen surface. To clean large oil stains on the surface of the screen, you need to use detergent to smear it first, and then use the above method to remove it. Compared with similar products from 3M, the cleaning power is equivalent, but the sprayed droplets tend to flow and are not easy to adhere to the screen, which is not as convenient as PM liquid.

Embodiment 3

[0033] PM as a rust and scale remover: Spray the PM solution on the rough surface of the sponge scouring pad, and then wipe it on the surface of stainless steel and copper products. Rust or scale stains on the surface of the product can be easily removed, which is much easier than scrubbing with decontamination powder; and the wiped surface looks bright and new, no need to clean again.

Abstract

The invention relates to a natural and mild functional surfactant as well as a preparation method and application of the natural and mild functional surfactant. The natural and mild functional surfactant consists of copolymers of phosphoenolpyruvic acid sylvite (PEPK) and acrylamide (AM). The preparation method comprises the following steps that PEPK and AM are used as monomers, wherein the weight ratio of the PEPK to the AM is 1:(0.5-1):50, and water solution obtained through oxidizing and reducing free radicals by peroxysulphate / sulfite is subjected to polymerization reaction at the mild reaction temperature being 10 to 50 DEG C; after the polymerization reaction, absolute ethyl alcohol is used for treating reaction liquid, then, the drying is carried out at the temperature below 80 DEG C, and white solid copolymers are obtained, i.e. the natural and mild functional surfactant is obtained; and the natural and mild functional surfactant is applied in liquid crystal display cleaning agents, derusting and descaling agents, clothes washing and hair washing compatibility, water quality treatment agents and chemical fertilizers. The natural and mild functional surfactant, the preparation method and the application have the advantages that the PEPK-AM copolymers are easily dissolved in water, the water solution does not stimulate skin and eyes, the natural and mild effects are realized, and the characteristics that the cleaning effect is very good, and the plant absorption is very easy.

Description

【Technical field】 [0001] The invention relates to the technical field of surfactants, in particular to a natural mild functional surfactant and its preparation method and application. 【Background technique】 [0002] The existing surfactants or laundry detergents generally have a better effect on removing fabric stains, but generally have the deficiency of rich foam. For example, the domestic brand Blue Moon laundry detergent, and the brand product Omo laundry detergent, when a little too much is added during use, it will be difficult to remove the foam during the rinsing process, and the final rinsing water solution is not clear enough, resulting in fresh fabrics after washing. Not feeling enough. [0003] The existing surfactants or shampoos generally have a better washing effect on hair, but generally have the disadvantage of weak rinsing function. For example, the brand Pantene shampoo, when rinsing the hair with water after washing, the aqueous solution is not clear an...
