AI Technical Summary

Technical Problem

In existing technologies, cleaning external oil stains on the engines of special vehicles on the apron requires rinsing with water, which leads to oil stains polluting the apron environment. Furthermore, traditional cleaning agents are costly, inefficient, and cannot be used frequently.

Method used

The cleaning agent contains alkyl glycosides, glycolipid anionic surfactants and secondary alcohol polyoxyethylene ethers. It is sprayed onto the oily surface to penetrate and then wiped clean, reducing water rinsing and waste liquid generation.

Benefits of technology

It achieves efficient cleaning of external engine oil stains, reduces pollution to the apron environment, lowers cleaning costs and time, and is suitable for environmentally friendly cleaning of special vehicles on the apron.

Abstract

The present application provides an engine cleaner, the cleaner contains surfactant and water, wherein the surfactant is alkyl glycoside, secondary alcohol polyoxyethylene ether and glycolipid anionic surfactant; the alkyl glycoside is C8-C16 alkyl glycoside, the secondary alcohol polyoxyethylene ether is selected from at least one of C8-C15 secondary alcohol polyoxyethylene ether, the number of ethylene oxide addition in the secondary alcohol polyoxyethylene ether is 3-30 or 4-20, the glycolipid anionic surfactant is selected from one or more of trehalose lipid, rhamnose lipid, sophorose lipid and mannose erythritol lipid; wherein, the content of the alkyl glycoside in the cleaner is 2-8wt%, such as 2.5-7wt% or 3-6.5wt%, the content of the glycolipid anionic surfactant is 10-20wt%, such as 12-18wt% or 13-17.5wt% or 14-16.5wt%, the content of the secondary alcohol polyoxyethylene ether is 7-12wt%, such as 8-10wt% or 9-9.5wt%, and the content of the surfactant is 20-35wt%, such as 23-30wt% or 25-29wt%. The cleaning agent product of the present application only needs to be sprayed on the oil stain surface, the penetration time is short, and the oil stain can be removed by simple and direct wiping, without generating a large amount of waste liquid and without polluting the ground.
