Problems solved by technology

[0004] In view of the problem of low flash point and high flammability risk of organic solvent cleaning agents on the market, the traditional method of adding toxic substances such as methylene chloride, trichloroethylene, and tetrachloroethylene can achieve the purpose of increasing the flash point, but because the additive itself is harmful to the human body It is highly toxic, so it has high protection requirements for operators and the environment

Abstract

The invention discloses an oil stain cleaning agent and a preparation method thereof, and the oil stain cleaning agent is prepared from the following raw materials in parts by weight: 10 to 20 parts of 2, 3-dimethyl butane, 10 to 20 parts of isohexane, 20 to 30 parts of heptane, 10 to 20 parts of n-decane, 5 to 10 parts of methyl cellosolve, 3 to 8 parts of ampholytic surfactant and 20 to 30 parts of dichlorofluoroethane. The oil stain cleaning agent disclosed by the invention has the beneficial effects that the 2, 3-dimethyl butane, the isohexane, the heptane, the n-decane, the methyl cellosolve and the ampholytic surfactant in the oil stain cleaning agent disclosed by the invention interact and have good oil stain cleaning performance, and the flash point of the oil stain cleaning agent is increased by adding the dichlorofluoroethane; the oil stain cleaning agent has the advantages of strong cleaning force, no toxicity, harmlessness, high flash point and nonflammability.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and particularly relates to an oil stain cleaning agent and a preparation method thereof. Background technique [0002] Oil stain cleaning agent is compounded by a variety of surfactants, penetrants and auxiliaries, and has the functions of penetrating, emulsifying, dispersing and glass. The oil cleaning agent is specially developed for the production process cleaning of metal parts in the machining process. It has excellent cleaning effect on grease, oil and mixed dirt. [0003] At present, the domestic industrial oil cleaning agent market is mainly divided into two types: organic solvent-based cleaning agents and water-based cleaning agents. Organic solvent-based cleaning agents have the advantages of fast volatilization, strong cleaning power, and less waste liquid. However, there are some cleaning agents. Low flash point, high flammability risk, some high flash point cleaning agents ...
