Abstract

The invention discloses an industrial heavy oil dirt cleaning agent. The industrial heavy oil dirt cleaning agent comprises the following components: an anionic surfactant, a nonionic surfactant, polyethylene glycol, sodium metasilicate, triethylamine, a terpene compound, inorganic base, an emulsifier and water. The industrial heavy oil dirt cleaning agent has a remarkable removal effect on heavyoil dirt attached to equipment, especially semi-solid heavy oil dirt; the stability is excellent; and moreover, the industrial heavy oil dirt cleaning agent contains less organic solvent and is a low-toxicity solvent, so that no pressure is brought to the environment.

Description

technical field [0001] The invention belongs to the field of industrial cleaning, and in particular relates to a formula of an industrial heavy oil dirt cleaning agent and a preparation method thereof. Background technique [0002] Industrial equipment will accumulate a large amount of heavy oil dirt during daily production and maintenance, and its types are mainly various cutting fluids, lubricating oils and anti-rust greases left in the processing process. Therefore, regular cleaning of industrial machinery and equipment is required. Since the development of industrial cleaning, it has penetrated into all industrial fields, such as machinery, textile printing and dyeing, petrochemical industry, mining and smelting, chemical industry, surface treatment, instrumentation, electronics, semiconductor, watch jewelry, biomedicine, electronic optics and other industries. The current cleaning agents are mainly divided into three types: water-based cleaning agents, solvent cleaning...
