Description

Technical Field

[0001] This invention belongs to the field of rust-preventive aerosol technology, specifically relating to a general-purpose rust-preventive lubricating oil aerosol and its preparation method. Background Technology

[0002] Rusting, a common natural phenomenon, has a significant impact on both daily life and industrial production. From household goods to industrial equipment, the corrosion of metal materials not only shortens their lifespan but also creates safety hazards and economic burdens. In daily life, hardware such as door locks, bicycles, and sliding rails are prone to rusting in humid environments. Once rust occurs, it increases the difficulty of operation, undoubtedly affecting usability and leading to increased living expenses. In industrial production, rust makes metal surfaces rough and uneven, hindering operation, reducing the strength and toughness of metal materials, and ultimately causing equipment failure or a decline in processing quality.

[0003] With technological advancements and evolving market demands, the application prospects of rust-preventive lubricating aerosols are expanding. In the industrial sector, rust-preventive lubricating aerosols play an indispensable role in automobile manufacturing, machining, and power industries. In automobile manufacturing, they protect critical components such as the chassis and engine parts, preventing rust and wear and ensuring long-term stable operation. In machining, they provide lubrication and protection for various metal processing equipment, extending equipment lifespan and improving production efficiency. The power industry has extremely high requirements for corrosion resistance of metal components, and rust-preventive lubricating aerosols meet these stringent requirements, ensuring safe equipment operation. With the increasing prevalence of smart homes, the application of rust-preventive lubricating aerosols in households is also becoming more widespread. Door locks, hinges, sliding rails, and other hardware in homes are prone to rusting in humid environments; using rust-preventive lubricating aerosols can easily solve these problems and extend the lifespan of these hardware components. Furthermore, sports equipment, gardening tools, bicycles, and other items frequently require rust prevention and lubrication, making rust-preventive lubricating aerosols an essential maintenance product for households. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an aerosol with multiple excellent properties such as rust prevention, lubrication, cleaning and rust removal, and applicable to multiple fields.

[0005] Based on this, the first aspect of the present invention provides a general-purpose rust-preventive lubricating oil aerosol, comprising, by mass percentage: 80%-90% base oil, 1%-5% film-forming agent, 2%-8% rust inhibitor, 0.3%-5% lubricant, and 0.1%-0.5% dehydrating agent; wherein the base oil is composed of solvent oil D80 and mineral oil 500N in a mass ratio of (3.5-4.5):1.

[0006] The aerosol of this invention can form a protective film on the metal surface, isolating moisture and air, and preventing rusting for a long time. Simultaneously, it can penetrate to form an oil film, reducing friction and wear, maintaining the flexible operation of metal parts, and further penetrating into capillaries to dissolve corrosion deposits such as rust particles, causing rust and other deposits to fall off and loosening bolts. Furthermore, the aerosol of this invention can remove grease, dirt, and dust adhering to the metal surface, keeping the metal surface bright and clean; and improve the conductivity of circuits, enabling the starting of wet engines. Specifically, solvent oil D80 and mineral oil 500N are selected in a specific proportion and ratio as base oils. This satisfies the requirements for volatility and penetration, allowing for uniform distribution and rapid drying on the metal surface to support the aforementioned technical effects. It also better ensures that rust inhibitors and other additives such as lubricants are uniformly dispersed in this specific base oil system, ensuring the formation of a uniformly distributed protective film on the metal surface and improving the rust-preventive effect.

[0007] The aforementioned rust inhibitor is at least one of calcium-based rust inhibitors (HY-023, ALOX 2100, T106, T705C, AR-01, HY-095CA, etc.) and sodium-based rust inhibitors (NA SUL SS, SPS 600, DH 526, T702A, etc.). In some preferred embodiments, the aforementioned rust inhibitor is composed of rust inhibitor NA SUL SS, rust inhibitor SPS 600, and rust inhibitor ALOX 2100 in a mass ratio of 1:2:0.5. Based on theoretical research and continuous experimentation, the inventors have discovered that, under the specific base oil system of this invention, the aerosol prepared using the aforementioned specific composition of rust inhibitor can better provide chemical and physical protection (preventing moisture and oxygen from contacting the metal), thereby more effectively preventing metal corrosion.

[0008] The film-forming agent is at least one selected from butyl paraffin oxide, paraffin oxide, lanolin, lanolin magnesium soap, and dimethyl silicone oil. In some preferred embodiments, the film-forming agent is composed of lanolin and dimethyl silicone oil in a 2:1 mass ratio. Based on theoretical research and continuous experimentation, the inventors have discovered that, under the specific base oil system of this invention, the film-forming agent with the above-mentioned specific composition can synergistically work with the above-mentioned specific rust inhibitor, thereby further improving the salt spray and damp heat resistance of the aerosol and extending the rust prevention period.

[0009] The aforementioned lubricant is at least one selected from phosphite ester, high-base-value calcium sulfonate, sulfurized fatty acid ester, fatty acid methyl ester, high-viscosity complex ester 9505, methanol phosphate ammonium salt, dialkyl thiophosphate derivative, phosphate amine mixture 349, ISOFOL 16, and ISOFOL 23. In some preferred embodiments, the lubricant is composed of phosphite ester 253 and dialkyl thiophosphate derivative 353 in a mass ratio of 1:0.3. Based on theoretical research and continuous experimentation, the inventors have discovered that, under the specific base oil system of this invention, the use of the lubricant with the above-mentioned specific composition can further improve rust prevention performance while also further improving the lubrication performance of metal parts, extending their service life, and ensuring the normal operation of equipment.

[0010] In some preferred embodiments, the dehydrating agent is DW 553. Using this dehydrating agent can more effectively adsorb and disperse moisture on the metal surface, decomposing or removing moisture through a chemical reaction, thereby further reducing the humidity of the alkali metal surface and decreasing the likelihood of corrosion. Simultaneously, it enables the aerosol to form a more uniform and denser protective film on the metal surface, further improving the rust prevention effect, extending the service life of metal products, and enhancing its applicability to various fields such as different metal materials and industrial production needs.

[0011] In some preferred embodiments, the above-mentioned general-purpose rust-inhibiting lubricating oil aerosol comprises, by weight percentage: 75.4% of solvent oil D80, 18.0% of mineral oil 500N, 1.5% of film-forming agent, 3.5% of rust inhibitor, 1.3% of lubricant, and 0.3% of dehydrating agent; wherein the rust inhibitor is composed of rust inhibitor NA SUL SS, rust inhibitor SPS 600, and rust inhibitor ALOX 2100 in a weight ratio of 1:2:0.5; the film-forming agent is composed of lanolin and dimethyl silicone oil in a weight ratio of 2:1; the lubricant is composed of phosphite 253 and dialkyl thiophosphate derivative 353 in a weight ratio of 1:0.3; and the dehydrating agent is DW553. This particular aerosol has a suitable viscosity (3.5 mm at 40°C). 2 It has excellent rust prevention, volatility, penetration and lubrication properties, and can penetrate into the metal surface, i.e., the inside of the capillary, so as to achieve better lubrication, rust removal and rust prevention effects.

[0012] A second aspect of the present invention provides a method for preparing the above-mentioned general-purpose rust-preventive lubricating oil aerosol, comprising the following steps:

[0013] The above-mentioned rust inhibitor and base oil are mixed at 55℃-65℃, and then the above-mentioned film-forming agent is added and mixed again. Then, the above-mentioned lubricant and dehydrating agent are added sequentially at 35℃-45℃ and mixed thoroughly. The mixture is then filled using a propellant to obtain the above-mentioned general-purpose rust-inhibiting lubricating oil aerosol. CO2 is preferably used as the propellant, as it is safer and more environmentally friendly than propane or butane propellants.

[0014] The beneficial effects of the present invention are as follows: The aerosol provided by the present invention can not only solve the problem of product quality affected by rust in daily life and industrial production, but also its excellent multifunctionality can effectively solve the corrosion of metal materials, provide better rust protection, and increase the lubrication performance of metal materials. Its excellent penetrability can effectively break down rust, deposits and other substances on the surface of metal materials, and keep the metal surface clean and bright. Detailed Implementation
