Description

Technical Field

[0001] The invention relates to the technical field of hydrocarbon cleaning agents, and in particular to a hydrocarbon cleaning agent for preventing metal surface oxidation and a preparation method thereof. Background Art

[0002] In daily life, iron and steel parts are easily rusted due to contact with air containing moisture and oxygen, so iron parts need to be treated with rust prevention after cleaning. In the prior art, rust prevention oil is usually used for rust prevention, but rust prevention oil has poor cleaning power, poor cleaning effect on metal chips and processing chips, and cannot clean the rusted parts. It has high viscosity and is not conducive to cleaning, so it can only be used as rust prevention oil.

[0003] Therefore, there is an urgent need for a hydrocarbon cleaning agent for preventing metal surface oxidation and a preparation method thereof to solve the deficiencies of the prior art. Summary of the invention

[0004] The purpose of the present invention is to provide a hydrocarbon cleaning agent for preventing metal surface oxidation, so as to solve the problem that the current anti-rust oil has poor cleaning power and single function.

[0005] To solve the above technical problems, according to one aspect of the present invention, more specifically, a hydrocarbon cleaning agent for preventing metal surface oxidation comprises the following components: hydrocarbons, alcohol ether compounds, organophosphorus compounds, phenolic free radical reaction terminators, oxygen scavengers, crown ether compounds, hypophosphites, glacial acetic acid, amide compounds, sulfoxide compounds, and higher fatty alcohol sulfate compounds.

[0006] Hydrocarbons are used as the main component to remove oil stains on the surfaces of iron and steel parts; high-grade fatty alcohol sulfate compounds are used as surfactants to enhance the ability to remove stains on the surfaces of iron parts. At the same time, because of their lipophilic and hydrophilic properties, the small amount of water that enters the cleaning agent during use will not become turbid due to the mixing of water and emulsions; alcohol ether compounds, amide compounds, and sulfoxide compounds are used as solubilizers to increase the solubilization effect between crown ether compounds, oxygen scavengers, organic phosphorus compounds and hydrocarbons, thereby improving the stability of hydrocarbon cleaning agents that prevent metal surface oxidation, and at the same time can further improve the effect of removing oil stains; phenol free radical reaction terminators and oxygen scavengers are used as anti-rust additives, which can form a strong force with the surface of iron parts and thus form a stable The invention discloses a novel novel cleaning agent for cleaning the surface of iron parts and steel parts, and adopts a novel method to form an anti-oxidation protective film, thereby delaying the rust caused by the contact of the iron and steel surfaces with air and moisture; adopts crown ether compounds as inorganic salt solubilizers, wherein the crown ether compounds and sodium or potassium atoms form supramolecules through ion complexation, and then bring the inorganic salts into the organic phase, so that the inorganic salts can be dissolved in the organic solvent, thereby avoiding the instability of the system caused by the precipitation of inorganic salts due to the volatilization of the solvent; adopts organic phosphorus compounds as flame retardants, reduces the flammability of the organic system, and increases the safety of use; adopts glacial acetic acid and hypophosphite, through local acid-base reaction and reduction reaction with the rust spots on the surface of iron parts, the rust spots are repaired in situ, which will not cause the surface roughness caused by rust, and the related reactions can form an internal cycle, so that the cleaning agent can be reused many times.

[0007] Therefore, the above hydrocarbon cleaning agent is particularly suitable for cleaning iron parts to remove oil stains and rust spots on the surface of iron parts and steel parts, and can also delay the rusting of iron parts and steel parts.

[0008] Furthermore, the hydrocarbon cleaning agent includes the following components in parts by weight: 75 to 85 parts of hydrocarbons, 5 to 15 parts of alcohol ether compounds, 2 to 5 parts of organic phosphorus compounds, 0.5 to 10 parts of phenol free radical reaction terminators, 0.1 to 2 parts of oxygen scavengers, 2 to 4 parts of crown ether compounds, 1 to 2 parts of hypophosphites, 0.1 to 0.2 parts of glacial acetic acid, 0.5 to 3 parts of amide compounds, 1 to 4 parts of sulfoxide compounds, and 2 to 6 parts of higher fatty alcohol sulfate compounds.

[0009] Furthermore, the weight ratio of the phenolic free radical reaction terminator to the oxygen scavenger is 5: 1.

[0020] Furthermore, the higher fatty alcohol sulfate compound of the present invention includes at least one of 2-propylheptanol polyoxyethylene ether sodium sulfate, dodecyl alcohol polyoxyethylene ether sodium sulfate, and isooctyl alcohol sodium sulfate.

[0021] According to another aspect of the present invention, a method for preparing a hydrocarbon cleaning agent for preventing metal surface oxidation is provided, comprising the following steps: S1, adding a formula amount of a higher fatty alcohol sulfate compound to a sulfoxide compound, stirring to dissolve, and recording as a first mixed system; S2, adding the crown ether compound to the first mixed system obtained in step S1, mechanically stirring to dissolve, adding hypophosphite, stirring to dissolve, and recording as the second mixed system; S3, add a formula amount of hydrocarbons to a single-mouth bottle, add amide compounds under stirring, mix well, add alcohol ether compounds, mix well, and record as the third mixing system; S4, slowly adding the second mixed system obtained in step S2 to the third mixed system obtained in step S3 under stirring, stirring for 5 to 10 minutes after the addition is completed, and recording it as the fourth mixed system; S5, adding the organophosphorus compound, the phenolic free radical reaction terminator, the oxygen scavenger, and the glacial acetic acid to the fourth mixed system obtained in step S4, stirring and mixing, and preparing a hydrocarbon cleaning agent for preventing metal surface oxidation.

[0022] In addition, the present invention also provides an application of a hydrocarbon cleaning agent for preventing metal surface oxidation in cleaning iron parts, wherein the hydrocarbon cleaning agent for preventing metal surface oxidation is used to perform ultrasonic heating cleaning on the iron parts and steel parts to be cleaned.

[0023] The hydrocarbon cleaning agent for preventing metal surface oxidation and the preparation method thereof of the present invention have the following beneficial effects: compared with the prior art, the hydrocarbon cleaning agent for preventing metal surface oxidation of the present invention not only has a strong decontamination ability and can wash away the oil stains on the surfaces of iron parts and steel parts, but also can repair the rust spots on the surfaces of iron parts, and form a protective film on the surfaces of iron parts and steel parts to achieve the effect of delaying oxidation and rusting, and has a certain flame retardant effect, and is safer. Moreover, since the reaction can be internally circulated to restore the related substances consumed in the process of repairing the rust spots, they can be reused many times, thereby reducing the use cost. Therefore, after the iron parts and steel parts are ultrasonically cleaned using the hydrocarbon cleaning agent for preventing metal surface oxidation of the present invention, not only can the oil stains and rust spots on the surfaces of the iron parts and steel parts be removed, but the oxidation and rusting of the iron parts and steel parts can also be delayed.
