Anionic surface active industrial detergent and preparation method thereof

Abstract

The invention discloses an anionic surface active industrial detergent and a preparation method thereof, and relates to the technical field of industrial detergents. The preparation method comprises the following steps: heating deionized water to 50-80 DEG C, simultaneously mixing fatty acid and sodium hydroxide for complete reaction to obtain a reactant, mixing water and the reactant under the conditions of keeping the temperature and stirring, adding prepared anionic surfactant, phosphate, sodium citrate and diethanol amine after mixing, stirring for 5-10 minutes, gradually adding the prepared o / w type emulsifier under an ultrasonic condition, continuously stirring for 3-5 minutes, gradually raising the temperature by 10-15 DEG C while stirring, stopping heating and ultrasonic treatment while stopping raising the temperature, continuously stirring and naturally cooling, adding sodium chloride when the system temperature is 40-50 DEG C, stirring and dissolving, and when the system temperature is cooled to normal temperature, adding a fluorescent whitening agent and a water-based antirust agent, uniformly mixing and storing; the detergent is good in cleaning and degreasing effect, high-temperature water soaking washing is not needed after washing, and other components can play a proper role.

Description

technical field [0001] The invention relates to the technical field of industrial detergents, in particular to an anionic surface active industrial detergent and a preparation method thereof. Background technique [0002] Industrial detergents are chemical or biological agents used in industry to remove dirt. Among all kinds of detergents, surfactants play a major role. The active principle is: in the molecular RH-X structure, RH Is a hydrocarbon hydrophobic group, X is a hydrophilic group. The compound of this structure can reduce the surface tension of its solution (generally an aqueous solution) and change the interface state of the system. When its solution reaches a certain concentration, it will produce micelles in the solution, thereby producing wetting, emulsifying, foaming, solubilizing and washing effects.

AI Technical Summary

Problems solved by technology

[0003] Metal materials are widely used in aviation, construction, transportation, electrical, chemical and other industrial fields. Lubricating oil is often used in various processing equipment. After a period of use, there will be more oil on the surface of the equipment, and if it is not cleaned in time, it will easily accumulate and affect the working environment. , will also hinder the heat dissipation of the equipment, so it needs to be cleaned regularly, but the washing effect of the existing industrial detergents still needs to be improved; for example, the publication number is CN112410135A, and the name is a patent application for an industrial cleaning agent for spraying and soaking. , which is made of safe and environmentally friendly dispersant, chelating agent, alkali, corrosion inhibitor, surfactant and solvent, which can not only reduce foam, but also prevent corrosion, but its optimal embodiment has only a 10-minute cleaning effect on oil stains 90%
