[0001] The invention belongs to the technical field of rust-proof aerosols, and in particular relates to a universal rust-proof lubricating oil aerosol and a preparation method thereof. Background Art

[0002] Rust, a common natural phenomenon, has a certain impact on daily life and industrial production. From household items to industrial equipment, the corrosion of metal materials not only shortens their service life, but also brings safety hazards and economic burdens. In daily life, hardware such as door locks, bicycles, and sliding rails are prone to rust due to humid environments. Once problems occur, it will increase the difficulty of operation, which will undoubtedly affect the use and increase living expenses. In industrial production, the metal surface becomes rough, uneven, and difficult to operate due to rust, which reduces the strength and toughness of the metal material, thereby causing equipment failure or reduced processing quality.

[0003] With the advancement of science and technology and the continuous evolution of market demand, the application prospects of anti-rust lubricating aerosol are broader. From the perspective of the industrial field, anti-rust lubricating aerosol plays an indispensable role in automobile manufacturing, mechanical processing, power and other industries. In the process of automobile manufacturing, anti-rust lubricating aerosol can be used to protect key parts such as the chassis and engine parts of the car body, prevent rust and wear, and ensure the long-term stable operation of the car. In the field of mechanical processing, it can provide lubrication and protection for various metal processing equipment, extend the service life of the equipment, and improve production efficiency. The power industry has extremely high requirements for the anti-corrosion of metal parts. Anti-rust lubricating aerosol can meet these strict requirements and ensure the safe operation of equipment. With the popularization of smart homes, the application of anti-rust lubricating aerosol in homes is becoming more and more extensive. Door locks, hinges, sliding rails and other hardware in the home are prone to rust due to humid environments. The use of anti-rust lubricating aerosol can easily solve these problems and extend the service life of hardware. In addition, sports equipment, gardening tools, bicycles, etc. often require rust prevention and lubrication treatment. Anti-rust lubricating aerosol has become one of the essential maintenance products for the home. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and provide an aerosol having 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 universal anti-rust lubricating oil aerosol, which comprises, 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; 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 the present invention can form a protective film on the metal surface, isolate moisture and air, and prevent the metal from rusting for a long time; at the same time, it can penetrate to form an oil film, reduce friction and wear, keep the metal parts flexible, and can further penetrate into the pores, dissolve corrosion sediments such as rust particles, make rust and other sediments fall off, and loosen bolts; in addition, the aerosol of the present invention can also remove attachments such as grease, dirt and dust adhering to the metal surface, keep the metal surface bright and clean; and improve the conductivity of the circuit and start the wet engine. Among them, solvent oil D80 and mineral oil 500N with a specific proportion and ratio are specially selected as base oils. On the one hand, it can meet the requirements of playability and permeability, so that it can be evenly distributed on the metal surface and quickly dried to form a film to support the realization of the above-mentioned technical effects; on the other hand, it can also better ensure that other additives such as rust inhibitors and lubricants can be evenly dispersed in the specific base oil system, ensuring that a layer of evenly distributed protective film is formed on the metal surface to enhance the anti-rust effect.

[0007] Wherein, the above-mentioned rust inhibitor is at least one of a calcium-based rust inhibitor (HY-023, ALOX 2100, T106, T705C, AR-01, HY-095CA, etc.) and a sodium-based rust inhibitor (NA SUL SS, SPS 600, DH 526, T702A, etc.). In some preferred embodiments, the above-mentioned 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 experiments, the inventors found that under the specific base oil system of the present invention, the aerosol prepared by using the rust inhibitor of the above-mentioned specific composition can better provide chemical and physical protection (prevent moisture and oxygen from contacting the metal), thereby more effectively preventing the occurrence of metal corrosion.

[0008] The film-forming agent is at least one of butyl oxidized paraffin, oxidized paraffin, lanolin, lanolin magnesium soap and dimethyl silicone oil.

[0009] The lubricant is at least one of phosphite, high base calcium sulfonate, sulfurized fatty acid ester, fatty acid methyl ester, high viscosity complex ester 9505, methanol phosphate ammonium salt, dialkyl thiophosphoric acid derivative, phosphoamine mixture 349, ISOFOL 16 and ISOFO L 23. In some preferred embodiments, the lubricant is composed of phosphite 253 and dialkyl thiophosphoric acid derivative 353 in a mass ratio of 1:0.3. Based on theoretical research and continuous experiments, the inventors found that under the specific base oil system of the present invention, the use of the lubricant of the specific composition can further improve the anti-rust performance, and can also further improve the lubrication performance of metal parts, extend their service life, and ensure the normal operation of the equipment.

[0010] In some preferred embodiments, the dehydrating agent is DW 553. The dehydrating agent can more effectively absorb and disperse the moisture on the metal surface, decompose or remove the moisture through chemical reaction, thereby further reducing the humidity on the surface of the alkali metal and reducing the possibility of rust; at the same time, the aerosol can form a more uniform and denser protective film on the metal surface, thereby further improving the anti-rust effect, extending the service life of metal products, and improving the applicability to different metal materials and industrial production needs.

[0011] In some preferred embodiments, the universal anti-rust lubricating oil aerosol comprises, by mass percentage: 75.4% of the solvent oil D80, 18.0% of the mineral oil 500N, 1.5% of the film former, 3.5% of the rust inhibitor, 1.3% of the lubricant and 0.3% of the 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 mass ratio of 1:2:0.5; the film former is composed of lanolin and dimethyl silicone oil in a mass ratio of 2:1; the lubricant is composed of phosphite 253 and dialkylthiophosphoric acid derivative 353 in a mass ratio of 1:0.3; the dehydrating agent is DW553. The specific aerosol has an appropriate viscosity (viscosity of 3.5 mm at 40°C). 2 / s), and has very good rust resistance, volatility, permeability and lubricity, and can penetrate into the metal surface, that is, the inside of the capillary pores, so as to achieve better lubrication, rust removal and rust prevention effects.

[0012] The second aspect of the present invention provides a method for preparing the above-mentioned universal anti-rust lubricating oil aerosol, comprising the following steps:

[0013] The above rust preventive and the above base oil are mixed at 55°C-65°C, and then the above film-forming agent is added and mixed; then the above lubricant and the above dehydrating agent are added in sequence at 35°C-45°C, mixed, and then filled with a propellant to obtain the above universal antirust lubricating oil aerosol. Among them, CO2 is preferably used as the propellant, which is safer and more environmentally friendly than propane 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 quality problem of products affected by rust in daily life and industrial production, but also its excellent multifunctionality can effectively solve the rust of metal materials, provide them with better anti-rust protection, and increase the lubrication performance of metal materials.
