Description

Technical Field

[0001] The invention belongs to the technical field of protection of metal materials, and in particular relates to a long-lasting rust-proof and high-lubricating easy-to-clean rust-proof oil and a preparation method thereof. Background Art

[0002] Metal materials, especially steel products, are very prone to rust in harsh environments such as humidity, acid and alkali, which not only shortens the service life of the materials, but may also cause a series of safety problems. Therefore, how to effectively prevent metal rust and improve the service life and performance of materials has always been the focus of attention in the industry and academia. As one of the important means of metal rust prevention, the performance of rust-proof oil directly affects the protective effect of metal materials. Although traditional rust-proof oil can prevent metal from contacting with moisture and oxygen to a certain extent, thereby inhibiting the occurrence of rust, they often have problems such as insufficient lubrication performance, unsustainable rust-proof effect, and difficulty in cleaning after use. In modern industry, especially in high-end fields such as machinery manufacturing, automobile manufacturing, and aerospace, higher requirements are placed on the performance of rust-proof oil. In addition to the basic rust-proof function, it is also necessary to have good lubrication performance to reduce friction and wear of mechanical equipment and improve the operating efficiency and service life of equipment. At the same time, with the increasingly stringent environmental protection regulations and the improvement of people's environmental awareness, the easy cleaning of rust-proof oil has also become an important evaluation indicator. Easy-to-clean rust-proof oil can not only reduce energy consumption and the use of chemical reagents during the cleaning process, reduce environmental pollution, but also improve equipment maintenance efficiency and reduce downtime. However, to achieve the long-term rust prevention, high lubrication performance and easy cleaning of rust-proof oil at the same time, it requires in-depth research and innovation in the formulation design and preparation process of rust-proof oil. Summary of the invention

[0003] The present invention develops a new type of high-performance anti-rust oil product through innovative formula design and preparation process to meet the high requirements of modern industry for anti-rust protection of metal materials. This new type of anti-rust oil product can not only improve the anti-rust protection effect of metal materials, effectively extend the service life of metal materials, reduce material loss caused by rust, but also reduce equipment maintenance costs and downtime, and improve equipment operation efficiency and service life.

[0004] In order to achieve the above-mentioned invention object, the present invention provides a long-term rust prevention and high lubricity easy-to-clean rust-proof oil, the rust-proof oil comprises the following components in parts by weight: 50 to 70 parts of compounded deep refined mineral oil, 15 to 25 parts of compounded synthetic oil, 8 to 12 parts of compounded high-efficiency rust inhibitor, 4 to 6 parts of compounded extreme pressure anti-wear agent, 1 to 4 parts of compounded oiliness agent, 0.5 to 5 parts of compounded antioxidant, 0.5 to 3 parts of compounded metal passivator, 0.5 to 3 parts of compounded viscosity index improver, and 0.5 to 3 parts of compounded easy-to-clean surfactant.

[0005] In the above technical solution, further, the compounded deeply refined mineral oil is prepared by mixing light mineral oil and medium mineral oil in a weight ratio of (6-7):3, and the compounded deeply refined mineral oil is used as the base oil component.

[0006] The composite oil is prepared by mixing poly-alpha-olefin synthetic oil, ester synthetic oil and polyether synthetic oil in a weight ratio of (2-3):2:1. The composite oil can make the lubricant have excellent low-temperature fluidity, high-temperature stability and oxidation resistance.

[0007] The compound high-efficiency rust preventive is prepared by mixing petroleum barium sulfonate, dodecenylsuccinic acid and calcium sulfonate in a weight ratio of (1-2):2:1. The compound rust preventive can provide a long-term and effective rust preventive effect for the metal surface.

[0009] The compound oiliness agent is prepared by mixing rapeseed oil and stearic acid in a weight ratio of (3-4):1. The compound oiliness agent can ensure that the lubricant has good adhesion and lasting lubrication effect on the metal surface.

[0010] Furthermore, the compound antioxidant is prepared by mixing 2,6-di-tert-butyl-p-cresol, N-phenyl-α-naphthylamine and phenothiazine in a weight ratio of (1-2):2:1. The compound antioxidant is a key component for protecting the lubricant from oxidative degradation.

[0011] The composite metal passivator is prepared by mixing sodium benzoate, benzotriazole and mercaptobenzothiazole in a weight ratio of (1-2):2:1. The composite metal passivator can form a protective film on the metal surface to isolate the metal from direct contact with the external environment, thereby effectively preventing metal oxidation. The protective film is dense, fine and uniform, not easy to fall off, and can protect the metal surface from corrosion by oxygen, water and chemicals for a long time.

[0012] Furthermore, the compound viscosity index improver is prepared by mixing polymethacrylate and polyisobutylene in a weight ratio of (6-7):3, which will ensure that the lubricant has stable viscosity performance under different temperature conditions.

[0013] The compound easy-to-clean surfactant is prepared by mixing fatty alcohol polyoxyethylene ether, sodium alkylbenzene sulfonate and alkylphenol polyoxyethylene ether in a weight ratio of (2-3):2:1. The compound easy-to-clean surfactant enhances the cleanability and compatibility of the lubricant.
