Description

Technical Field

[0001] The invention relates to a high-performance anti-rust oil composition and a preparation method thereof, and belongs to the field of soft film anti-rust oil. Background Art

[0002] With the continuous advancement of mechanical automation technology, the protection of metal parts from wear and corrosion has become an increasingly critical issue. As a special protective medium, anti-rust oil achieves long-term protection through the following dual mechanisms: first, it forms a dense protective film on the metal surface, effectively isolating the erosion path of corrosive media such as oxygen and moisture, and inhibiting electrochemical corrosion reactions; second, it exerts excellent lubrication properties, reduces the friction coefficient of the metal interface, and thus delays mechanical wear. Such comprehensive protective properties make anti-rust oil indispensable for the long-term storage and operation and maintenance of precision equipment and metal products. With the widespread application of anti-rust oil in the fields of steel, automobile manufacturing, aerospace, etc., the expansion of the steel industry, as the main application field of anti-rust oil, has driven the growth of demand for this product; the development of new energy vehicles and the upgrading of traditional automobile technology have also increased its demand in the automotive manufacturing industry.

[0003] Common rust-proof oils on the market can provide adequate rust prevention between processes and for some sealing applications, but they are less effective for marine applications. The complex marine environment, characterized by large temperature swings, high humidity, and high salt content, can reduce the effectiveness of rust-proof oils. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a high-performance anti-rust oil composition and a preparation method thereof, which has a longer salt spray anti-rust time and is beneficial for long-term protection of metals in high temperature and high humidity environments such as sea transportation.

[0005] The technical solution adopted by the present invention to solve its technical problem is: In a first aspect, the present application provides a high-performance rust preventive oil composition, comprising, by mass, 70 to 80 parts of a base oil, 1 to 3 parts of a film-forming agent, and 15 to 30 parts of a rust preventive agent, wherein the base oil is selected from at least one of 10# white oil, 60N base oil, 150N base oil, and 500N base oil; the rust preventive agent is selected from at least five of barium petroleum sulfonate, sodium sulfonate, calcium petroleum sulfonate, barium dinonylnaphthalene sulfonate, dodecenylsuccinic acid, alkenylsuccinic acid half ester, and sorbitan monooleate; and the film-forming agent is selected from at least two of oxidized paraffin butyl ester, oxidized wax, lanolin pentaerythritol ester, and lanolin magnesium soap.

[0006] The high-performance rust-proof oil composition provided in this application uses a specific combination of base oil, film-forming agent, and rust inhibitor. Within the dosage range, the components cooperate with each other to provide a dense oil film base to effectively isolate salt spray.

[0007] Furthermore, the high performance anti-rust oil composition has a viscosity of 16 mm at 40°C. 2 / s ~59mm 2 / s.

[0008] Optionally, the base oil comprises 70% to 80% by mass, the film-forming agent 1% to 3% by mass, and the rust inhibitor 19% to 28% by mass.

[0009] By optimizing the ratio of base oil, film-forming agent and rust inhibitor, a better synergistic effect can be achieved among the three, which can further improve the comprehensive performance of the rust-proof oil composition, such as rust prevention performance and stability, thereby more effectively resisting corrosive media and extending the rust protection time of metals.

[0010] Furthermore, the base oil is 10# white oil, more preferably paraffin-based 10# white oil.

[0011] Compared with other optional base oils, 10# white oil can better meet the permeability, solubility and lubricity requirements of high-performance rust-proof oils, making the rust inhibitor and other additives more evenly dispersed in the oil. The adsorption film formed by the combination of its base oil molecules and rust inhibitor molecules is denser and more complete, thereby significantly improving the anti-rust effect of the rust-proof oil composition and enhancing the protection of the metal surface. In practical applications, it can more effectively prevent metals from rusting and wearing in various environments.

[0012] Furthermore, the calcium sulfonate is selected from at least one of Arcot 625 neutral petroleum calcium sulfonate, Arcot NH302 medium-base petroleum calcium sulfonate, AR-01 synthetic calcium sulfonate, and T106 high-base synthetic calcium sulfonate.

[0013] These specific calcium sulfonates can be more effectively combined with other rust inhibitors in rust-proof oil to exert chemical and physical protective effects.

[0014] Furthermore, the rust inhibitor comprises T701 barium petroleum sulfonate, T705 barium dinonylnaphthalene sulfonate, T746 dodecenylsuccinic acid, Arcot 625 neutral calcium petroleum sulfonate and Span 80 sorbitan monooleate.

[0015] By selecting a variety of rust inhibitors with complementary functions for compounding, the components can play a synergistic role, which significantly improves the density and protective stability of the anti-rust film as a whole. It is particularly suitable for high salt spray and high humidity transportation environments.

[0016] Furthermore, the rust inhibitor's weight ratio of T701 barium petroleum sulfonate: T705 barium dinonylnaphthalene sulfonate: T746 dodecenylsuccinic acid: Arcot 625 neutral calcium petroleum sulfonate: Span 80 sorbitan monooleate is 12:6:6:2:1.5. This allows for optimal synergy within the compound system, fully leveraging their respective anti-rust advantages to create an optimal anti-rust film structure and performance. Compared to other ratios, this combination maximizes the anti-rust performance of the anti-rust oil composition, significantly extending the duration of rust protection in salt spray testing and improving its ability to protect metals from rust in harsh environments.

[0017] Furthermore, the oxidized wax includes at least one of oxidized paraffin and HY-6070 oxidized wax.

[0018] Furthermore, the film-forming agent comprises EX985 oxidized paraffin butyl ester and HY-6070 oxidized wax.

[0019] The combination of the two can effectively improve the ductility and flexibility of the oil film, enhance the film integrity and corrosion resistance in harsh environments such as temperature changes and salt spray erosion, and ensure that the rust-proof oil provides a continuous and stable physical barrier during long-distance transportation or sea transportation.

[0020] Furthermore, the film-forming agent features a ratio of 3:1 (by mass) of EX 985 oxidized paraffin butyl ester to HY-6070 oxidized wax, achieving optimal synergy in the composite film-forming agent, resulting in a protective film with optimized structure and performance. This ratio allows the film to better adapt to complex environments, offering enhanced resistance to erosion and penetration. Compared to other ratios, it significantly improves the rust-preventive performance of the rust-preventive oil composition and extends the rust protection period of metals.

[0021] In a second aspect, the present application provides a method for preparing the high-performance rust-proof oil composition as described in the first aspect, the steps comprising: stirring the base oil, heating it to 60±5° C., adding the rust inhibitor and the base oil, mixing and stirring, and then adding the film-forming agent. After the film-forming agent is dissolved, the high-performance rust-proof oil composition is obtained.

[0022] Through a specific preparation method, the process is carried out at 60±5°C, a temperature that ensures thorough mixing of the base oil, rust inhibitor, and additives, while effectively dissolving the film-forming agent without compromising the properties of the components. This ensures that the components of the final high-performance rust-preventive oil composition are evenly mixed and have stable performance, fully utilizing the synergistic rust-preventive effects of the components, ensuring that the rust-preventive oil has good rust-preventive performance and stability, and meets testing requirements such as water displacement and lamination.

[0023] The beneficial effects of the present invention are as follows: the high-performance rust-proof oil composition of the present invention can simultaneously achieve excellent comprehensive protective properties such as physical isolation, chemical adsorption and salt spray resistance by optimizing the combination of the types and contents of base oil, rust inhibitor and film-forming agent, significantly improving the anti-rust effect in high-humidity and high-salt environments such as marine transportation, and having longer-lasting rust inhibition ability and better lubrication stability compared to conventional soft film rust-proof oils. DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be understood that, under the premise of no conflict, any and all embodiments of the present invention can be combined with the technical features in any other embodiment or multiple other embodiments to obtain additional embodiments. The present invention includes such combinations to obtain additional embodiments.

[0026] In this specification, groups and substituents thereof can be selected by those skilled in the art to provide stable structural moieties and compounds. When substituents are described by conventional chemical formulas written from left to right, the substituents also include chemically equivalent substituents obtained when the structural formula is written from right to left.

[0027] Unless otherwise specified, all technical and scientific terms used herein have the standard meanings in the art to which the claimed subject matter belongs. If there are multiple definitions for a term, the definition herein shall prevail.

[0028] In the description of this application, when only the trade name and brand are described, or when the trade name and brand appear at the same time as the chemical substance name, as long as the brand is the same, the three expression formats of "brand-chemical substance", "chemical substance-brand" and "brand" describe the same agent; when only the chemical substance name appears, the specific agent is not limited.

[0029] Existing soft-film anti-rust oils can provide rust prevention between processes and during storage, but they cannot meet the requirements for longer rust prevention cycles and more stringent transportation environments (such as high temperature and high humidity). Currently, hard-film anti-rust oils can meet the harsh conditions of marine transportation (high temperature, high humidity, and large temperature differences), but the subsequent cleaning process of hard-film anti-rust oils is more complicated and less convenient than soft-film anti-rust oils.

[0030] To this end, the present invention provides a high-performance anti-rust oil composition, which is a soft film anti-rust oil, comprising 70 to 80 parts by mass of base oil, 1 to 3 parts of film-forming agent, and 15 to 30 parts of rust inhibitor.

[0031] The preparation steps of the high-performance anti-rust oil composition include: stirring base oil, heating to 60±5° C., adding a rust inhibitor and mixing with the base oil, and then adding a film-forming agent, and obtaining the high-performance anti-rust oil composition after the film-forming agent is dissolved.

[0032] Through the mutual cooperation of various components, the high-performance anti-rust oil composition prepared can effectively meet the anti-rust protection needs of metal parts and equipment in complex environments, and make up for the defect that common anti-rust oils are not ideal in complex environments such as marine protection.

[0033] The components are detailed as follows: base oil Select deeply refined mineral oil or synthetic oil as base oil. Base oil is an important component of rust-proof oil. It not only serves as a carrier of rust inhibitor, but also enhances the rust-proof effect of rust inhibitor through physical adsorption and oil effect, while providing lubrication protection. Base oil can be mineral oils such as 10# white oil, 60N, 150N, and 500N. Preferably, base oil is 10# white oil. Preferred base oil can meet the permeability, solubility and lubricity of high-performance rust-proof oil, and can make rust inhibitor and other additives uniformly dispersed in oil. The hydrocarbon group of base oil molecule penetrates into the rust inhibitor molecules of directional adsorption, and blocks pores together with rust inhibitor molecules by van der Waals attraction, making the adsorption film on the metal surface more dense and complete, ensuring that they form a protective film on the metal surface, thereby accurately playing the rust-proof effect.

[0034] Rust inhibitor Rust-inhibiting additives effectively protect metal surfaces and prevent rust through adsorption, displacement, solubilization, and neutralization. The polar groups in the additive molecules have a strong adsorption force on metal surfaces, forming a tight monomolecular or multimolecular protective layer on the metal surface, preventing contact between corrosive media and the metal, thereby preventing rust. Rust-inhibiting additives displace water films and water droplets on the metal surface, allowing the oil film to directly contact and absorb the metal surface, thus protecting the metal from rust. Rust inhibitors can include T701 barium petroleum sulfonate, Arcot 625 neutral calcium petroleum sulfonate (Shanghai Zhenzhi Chemical Co., Ltd.), Arcot NH302 medium-base calcium petroleum sulfonate (Shanghai Zhenzhi Chemical Co., Ltd.), AR-01 synthetic calcium sulfonate (Dongguan Wonder New Materials Co., Ltd.), T106 high-base synthetic calcium sulfonate, sodium sulfonate NA SUL SS (King Industries), neutral barium dinonyl and naphthalene sulfonate T705, dodecenylsuccinic acid T746, alkenylsuccinic acid half ester T747, sorbitan monooleate Span 80, and the like. Preferably, the rust inhibitor is a combination of T701 barium petroleum sulfonate, T705 barium dinonylnaphthalene sulfonate, T746 dodecenylsuccinic acid, Arcot 625 neutral calcium petroleum sulfonate, and Span 80 sorbitan monooleate. The preferred rust inhibitor in the rust-proof oil mainly provides chemical and physical protection, preventing moisture and oxygen from contacting the metal, thereby effectively preventing the occurrence of metal corrosion.

[0035] film-forming agent Film-forming agents play a key role in isolating and reinforcing rust preventative oils. By forming a protective film, they effectively prevent metal corrosion and enhance the overall performance of the rust preventative oil. Examples of film-forming agents include EX985 oxidized paraffin butyl ester (from Wengkaier (Shanghai) International Trading Co., Ltd.), oxidized paraffin, pentaerythritol lanolin ester (for example, from Dongguan Hongli Chemical Technology Co., Ltd.), lanolin magnesium soap, and light-colored, low-odor oxidized wax HY-6070 (from Dongguan Wonder New Materials Co., Ltd.). Preferably, the film-forming agent is a combination of EX985 oxidized paraffin butyl ester and HY-6070 oxidized wax. This preferred film-forming agent can enhance the strength of the rust preventative oil film, preventing it from being washed away by condensation in salt spray and hot and humid environments, thereby improving the protective performance of the rust preventative oil.

[0036] Combining the above preferred technical features, a high-performance rust-preventive oil composition is obtained, by weight, comprising: 70.5% base oil, 27.5% rust inhibitor, and 2% film-forming agent. The rust-preventive additives comprise barium petroleum sulfonate T701, neutral dinonyl and barium naphthalene sulfonate T705, Arcot 625 neutral calcium petroleum sulfonate, T746 dodecenylsuccinic acid, and Span 80 sorbitan monooleate in a ratio of 12:6:6:2:1.5. The film-forming agents, butyl oxidized paraffin EX985 and HY-6070 oxidized wax, achieve optimal rust-preventive performance when combined in a ratio of 3:1. This high-performance rust-preventive oil composition exhibits moderate viscosity, a salt spray rust protection duration of up to 264 hours, and a salt spray protection duration of up to one month for aluminum test pieces. It exhibits excellent stability, exhibiting no precipitation from samples after long-term storage. It also meets requirements for water displacement and lamination tests, effectively enhancing rust protection for metal parts and equipment in harsh environments.
