Abstract

An environment friendly industrial oil stain cleaning agent is prepared from, by weight, 3.5 parts of sodium carbonate, 7.6 parts of ethylene diamine tetraacetic acid, 3 parts of sodium citrate, 7.5 parts of sodium alcohol ether sulphate, 4 parts of amine oxide, 1.4 parts of polyquaternium, 2 parts of sodium dodecylbenzenesulfonate, 3.6 parts of isopropyl alcohol, 3.4 parts of polyethyleneglycol, 2.4 parts of corrosion inhibitor, 1.5 parts of foam suppersor and 60 parts of water. The cleaning agent of the invention has high oil removal efficiency, free of ions of such heavy metals as manganese and chromium, chloridion, phosphorus and other toxic and harmful components. It is biodegradable, has no pollution to the environment and will not produce toxic or harmful gas during utilization. It will not cause human injury or environmental pollution. The corrosion rate caused by the cleaning agent to devices is very low, thus prolong the service life of devices.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an environment-friendly industrial oil stain cleaning agent and a preparation method thereof. Background technique [0002] In most industrial production operations, all kinds of devices and mechanical equipment will have various oil stains attached to them, so that operators and maintenance personnel can easily contaminate the oil stains on their bodies when they are working, so people will just arrive. discomfort. [0003] At the same time, the toxic and volatile materials in many equipment are often dissolved in the oil pollution during the processing, and spread out of the device or mechanical equipment along with the oil pollution. Moreover, since the pressure in the device or mechanical equipment is often greater than the pressure in the environment, the toxic and volatile materials are easy to vaporize and enter the air quickly, which will cause environmental pollution and c...
