Abstract

The invention relates to a cleaning agent for spraying. The cleaning agent is prepared from, by weight, 1-5% of fatty alcohol polyoxyethylene polyoxypropylene, 3-10% of silicon-modified alkynediols polyoxyethylene ether, 1-5% of first surfactant, 5-10% of second surfactant, 0.1-2% of complexing agent and the balance water. The structure of modified alkynediols polyoxyethylene ether is shown in thefirst formula, wherein R1, R2, R3 and R4 are independently selected from the H atom, the linear chain or the branched chain C1-C10 alkyl group; at least one of R1 and R2 is H or -CH3; at least one ofR3 and R4 is H or -CH3; m is an integer within the range of 0-50, n is an integer within the range of 0-50, and m and n are not 0 simultaneously. The invention provides a method for preparing the cleaning agent for spraying. The method has the advantages that the obtained cleaning agent for spraying is efficient and environmentally friendly, and high in oil stain surface spreadability and detergency, and has few foams and high alkali-resisting stability and hydrolysis resistance.

Description

technical field [0001] This application relates to the technical field of daily necessities for cleaning and care. Specifically, the application relates to a silicon-modified acetylenic glycol polyoxyethylene ether-containing cleaning agent for spraying and a preparation method thereof. Background technique [0002] As we all know, in production and life, there are many things that need to be cleaned, and there are many types and links that need to be cleaned, such as: oil cleaning on the surface of objects, dust removal or surface rust prevention, etc. Common manual cleaning methods are slow and costly, but spray cleaning can clean objects in batches, which has the advantages of high efficiency, strong controllability and low cost. Surfactants have strong wetting, emulsifying, washing and solubilizing abilities, and are important components of spray cleaning agents. At present, there are many kinds of surfactants that can be used for spray cleaning, but there are also the...
