Environmentally friendly industrial heavy oil cleaning agent

Abstract

The invention discloses an environmentally friendly industrial heavy oil cleaning agent. The environmentally friendly industrial heavy oil cleaning agent mainly comprises the following raw materials of 20-35% of sodium carbonate, 5-10% of sodium hydroxide, 5-10% of sodium silicate, 0.2-1% of sodium gluconate, 0.2-0.5% of benzotriazole, 15-35% of a composite surface active agent and the balance water. The composite surface active agent is at least one of alcohol alkoxylate, LMEO-18 and a low-foam type emulgator. The heavy oil cleaning agent is excellent in cleaning effect, capable of cleaning up heavy oil on various surfaces of machining equipment, machine tools, steel materials and the like, low in use amount and high in oil removal efficiency, and the cleaning rate for oil stains is up to 99% or above.

Description

technical field [0001] The invention belongs to the field of mechanical cleaning, and in particular relates to an environment-friendly industrial heavy oil cleaning agent. Background technique [0002] In the field of mechanical processing and other fields, it is very common to have oil stains on the metal surface. Usually, organic solvents or even gasoline are used to clean the oil stains on the metal surface. During the cleaning process, organic solvents will pose a threat to human health; at the same time, the waste liquid and waste gas generated during cleaning will also cause serious environmental pollution. At present, to realize the cleaning of heavy oil, a single surfactant is often used, but its consumption is large and the cost is high, and for some special oil stains, a single surfactant cannot achieve the cleaning function. In addition, there are also surfactant compound formulations used as cleaning agent products, such as linear alkylbenzene sulfonate sodium (...

AI Technical Summary

Problems solved by technology

During the cleaning process, organic solvents will pose a threat to human health; at the same time, the waste liquid and waste gas generated by cleaning will also cause serious environmental pollution

At present, to realize the cleaning of heavy oil, a single surfactant is often used, but its dosage is large and the cost is high, and for some special oil stains, a single surfactant cannot achieve the cleaning function

In addition, there are also surfactant compound formulations used as cleaning agent products, such as linear alkylbenzene sulfonate sodium (LAS) and alkylphenol polyoxyethylene ether (TX), etc. (Chinese patents 201410514429.2, 20081148043.9, 201410665872.x), A compound formula based on alkylphenol polyoxyethylene ether and fatty alcohol polyoxyethylene ether is usually used, but these two surfactants are not environmentally friendly, especially the alkylphenols are banned by the European Union or restricted in China

Moreover, the above-mentioned surfactants are difficult to degrade in nature and cause certain hazards to the human body and organisms.
