Embodiment 1～6

[0026] Pump the correctly measured base oil into the blending tank, heat and stir evenly, when the temperature of the oil product rises to 75°C, add viscosity-temperature index improver, friction modifier, and rust inhibitor in sequence, keep stirring at 65°C for 2.5 hours, When the oil temperature is cooled to 50°C, add antioxidant and anti-corrosion agent, extreme pressure and anti-wear agent in turn, and stir at constant temperature for 2 hours. Wherein each component and its weight percentage are shown in Table 1, and product performance is shown in Table 3.

Embodiment 7

[0030] The lubricating antirust oil of [embodiment 4] is evenly brushed on the steel wire rope, and the oil has good extreme pressure and antiwear properties, antirust and anticorrosion, permeability and adhesion, and the lubricating antirust oil can be used for a period of time. After the actual application, there is no flow down from the wire rope, and there is no phenomenon of hardening, cracking and falling off. At the same time, the wire rope coated with lubricating anti-rust oil has not been rusted within 6 months. The product performance is as follows:

[0031] Kinematic viscosity (40℃), mm 2 / sec 70.86

[0032] Viscosity index 130

[0033] Corrosion test (steel sheet, 100°C, 3 hours), level 0

Abstract

The invention relates to lubricating rust preventive oil and application thereof, mainly aiming to solve the problems of the prior art that: a rustproof product has poor adhering property; and the prior art only lays stress on rustproof property and does not attach equal importance to the extreme pressure property, oxidation resistance and permeability of a petroleum product. The lubricating rust preventive oil solves the problems better through adopting the following technical proposal that: the compositions in percentage by weight of the lubricating rust preventive oil are: (a) 0.1 to 10 percent of extreme pressure antiwear agent, (b) 0.5 to 15 percent of rustproof agent, (c) 0.5 to 5 percent of oxidation and corrosion inhibitor, (d) 0.1 to 15 percent of viscidity temperature index improver, (e) 0.1 to 12 percent of friction improver and (f) the balance being base oil. The lubricating rust preventive oil can be used in fields such as harbor machinery, excavator, travelling crane, cargo winch and commercial elevator cable.

Description

technical field [0001] The invention relates to a lubricating antirust oil and its application. Background technique [0002] Wire rope lubrication products have been widely used in port machinery, excavators, cranes, cargo hoists and commercial elevator cables, etc. The demand is gradually expanding. It not only requires good lubricity, but also good rust resistance. For a long time, steel wire ropes have been rust-proofed by using grease products such as wire rope surface grease, steel wire rope hemp core grease, and open gear grease. Document CN1854270A discloses a lubricating grease for steel wire rope protection. Based on the total weight of the composition, the weight content of each component is: (1) animal fat 10-50%; (2) hydrogenated oil 1-10%; wool Grease antirust agent 0.5-8%; (4) The balance of vegetable oil; wherein the hydrogenated oil is obtained from animal oil or vegetable oil through hydrogenation, the molecular weight is 850-890; the melting point of lano...
