Abstract

The invention relates to an environment-friendly safe solvent cleaning agent which specifically comprises the following components in parts by weight: 0-97 parts of C10-C12 alkanes, 3-100 parts of alcohol ether solvent, 0.00-0.01 part of antioxidant and 0.00-0.01 part of corrosion inhibitor. The environment-friendly safe solvent cleaning agent provided by the invention is narrow in boiling range and the distillation recovery rate of the environment-friendly safe solvent cleaning agent can be above 95%; the environment-friendly safe solvent cleaning agent is also high in clearing ability, and has strong cleaning ability for polar dirt and nonpolar dirt; especially, the environment-friendly safe solvent cleaning agent can be used for thoroughly cleaning various metal working fluids, and oil-based and water-based cutting fluids without any residual and corrosion on metals; moreover, the shortcoming that the previous hydrocarbon type cleaning agents are wide in boiling range and only capable of dissolving and cleaning the nonpolar dirt are overcome. The cleaning agent is perfect in balance of cleaning ability, safety, dryness and reproducibility.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning agents, in particular to an environment-friendly and safe solvent cleaning agent. Background technique [0002] In the field of industrial cleaning, halogenated hydrocarbon cleaning agents have always occupied a large proportion, such as: methylene chloride, trichloroethylene, tetrachloroethylene, etc. It is widely used because of its strong cleaning ability, non-combustion, fast drying, and easy distillation and regeneration. With people's concern and emphasis on environmental protection and personal health, problems such as high toxicity, corrosion, large evaporation loss, and environmental pollution of halogenated hydrocarbons have attracted more and more attention. my country has successively acceded to two international environmental conventions for the protection of the ozone layer, the Vienna Convention on the Protection of the Ozone Layer and the Montreal Protocol on Substances ...
