A kind of environment-friendly composite alkaline foam cleaning agent and preparation method thereof

Abstract

The invention discloses an environment-friendly composite alkaline foam cleaning agent and a preparation method thereof. The environment-friendly composite alkaline foam cleaning agent is prepared from water, sodium hydroxide, a foaming agent, a foam stabilizing agent, a dispersing agent, a chelating agent and alkylolamide. The foam cleaning agent has the advantages of being high in permeability,efficient, clean, easy to flush and the like, can form a large amount of rich and delicate foam in the use process, has long half-life and wall hanging time, can be attached to the surface of equipment for 25 min or longer, can rapidly infiltrate dirt to soften, loosen and emulsify the dirt, reduces adhesion of the dirt, can completely remove the dirt of the equipment and has lower cost.

Description

technical field [0001] The invention belongs to the technical field of alkaline cleaning agents, and in particular relates to an environment-friendly composite alkaline foam cleaning agent and a preparation method thereof. Background technique [0002] With the improvement of food safety awareness, people are paying more and more attention to the hygienic issues in food processing, and suitable cleaning agents are the prerequisite for meeting food hygiene standards. For industries such as meat and dairy processing, in order to remove stubborn dirt such as heavy oil and protein, alkaline cleaning agents are used. Alkaline cleaners can react with protein, fat, carbohydrates and other dirt to achieve the purpose of cleaning. [0003] The traditional method of cleaning fat or protein dirt is to spray a liquid alkaline cleaning agent on the surface to be cleaned. In this method, the cleaning agent flows faster, and the contact time between the active ingredient and the dirt is s...

AI Technical Summary

Problems solved by technology

However, the foam emitted during cleaning has weak adhesion, poor stability, weak mechanical properties between foam and foam, resulting in faster foam elimination or faster flow, shorter adhesion time on the surface to be washed, and insufficient cleaning.

[0005] Chinese patent CN106590960 discloses an alkaline foam cleaning agent for cleaning food dirt. Calculated according to mass percentage, the alkaline foam cleaning agent includes components: sodium hydroxide 4%~7%, chelating agent 1%~3 %, thickener 0.5%~10%, amine oxide 5%~15%, glycoside nonionic surfactant 5%~10%, isopropanol 1%~5% and pure water 50%~82%, other The disadvantages are: (1) the C selected in the above-mentioned published patent 8~10 Alkyl glycoside nonionic surfactants have poor resistance to hard water, and their foams are greatly affected by hardness and have high cost; (2) The thickeners described in the above-mentioned published patents are polyacrylamide, polyvinyl alcohol, sodium carboxymethyl cellulose , one of xanthan gum or its mixture, among which polyacrylamide and polyvinyl alcohol are synthetic high polymers, which are not easily soluble in water, even at a very low concentration, it is difficult to dissolve, and the resulting solution has a high viscosity , although it is conducive to the adhesion of foam on the surface of the equipment to be cleaned, it also largely inhibits the foaming volume of the diluent; (3) the above-mentioned published patent chelating agent is selected as a compound of organic phosphorus series and organic carboxylic acid series, Organophosphorus chelating agents have poor alkali resistance, are likely to cause water pollution, and increase environmental pressure; (4) the above-mentioned published patents have a long preparation period, and the preparation method includes adding pure water to the thickener, stirring and dissolving evenly, and the thickener polypropylene Amide and polyvinyl alcohol are insoluble in water, and excessive stirring will cause degradation. Carboxymethyl cellulose sodium and xanthan gum are both powders and have strong hydrophilicity. If they are directly added to water without sufficient stirring , the outer layer absorbs water and swells into micelles, thereby preventing water from entering the inner layer, affecting the system ratio and prolonging the production cycle
