Abstract

The invention discloses a sodium hexametaphosphate detergent preparation method, which comprises: 1, stirring sodium hexametaphosphate, Tween and sodium sulfonate to obtain a system A; 2, adding isopropylamine benzenesulfonate into the system A, and stirring to obtain a system B; 3, stirring betaine, phenoxyethanol and methylisothiazolinone to react for 2-5 h at the temperature of 30-60 DEG C to obtain a system C; 4, mixing the system B and the system C to obtain a mixture, and adding deionized water into the mixture under a stirring condition; and 5, cooling and sub-packaging to obtain the sodium hexametaphosphate detergent. According to the preparation method of the detergent, the material A and the material B are prepared respectively, generation of bubbles in the preparation process can be effectively reduced, material failure is prevented, sodium hexametaphosphate serves as a main component, grease residues can be effectively removed through the adsorption performance of sodium hexametaphosphate, and the detergent has the effects of efficient decontamination, bacteriostasis and sterilization and the like.

Description

technical field [0001] The invention belongs to the technical field of detergent, and in particular relates to a preparation method of sodium hexametaphosphate detergent. Background technique [0002] As a kind of decontamination product, dishwashing liquid is clean and mild, can quickly decompose grease, quickly decontaminate, bacteriostatic and sterilizing and other effects. Ether sulfate and the like are the main components, which have the disadvantages of narrow application range, easy residue and insufficient decontamination ability. [0003] Sodium hexametaphosphate is a white, odorless crystalline powder, insoluble in organic solvents, and has strong hygroscopicity. It can be complexed with metal magnesium, calcium, etc. to form soluble complexes. Sodium hexametaphosphate is often used as water softener, water treatment agent, corrosion inhibitor, flotation agent, dispersant, auxiliary agent, rust remover, cement hardener, etc. for industrial water. [0004] The co...
