[0004] 1. The dropping point is low (Sinopec SH / T0387 standard is not lower than 58°C), and the dropping point is generally around 70°C. In the hot summer season, it is easy to soften and lose during work and storage, resulting in oil shortage and pollution;
[0005] 2. Low viscosity (standard: ≮20), generally around 30 on the market, poor adhesion (regardless of work or storage), easy to be lost and polluted;
Poor performance in inhibiting oxidation and neutralizing acid bodies

preparation example Construction
[0028] The preparation process of the anti-oxidation and wear-resistant surface grease for steel wire ropes in the present invention is to put cycloalkyl oil and paraffin-based high-viscosity oil into the reaction kettle, stir and heat up to 110°C, and dehydrate after stirring slowly
[0029] Put into palm wax, Duroc pine wax in the process, heat up to 130 ℃, cool down.
[0030] During the cooling process, put in zinc dialkyldithiophosphate, diphenylamine, polyisobutylene, ethylene-propylene copolymer, calcium sulfonate, homogenize at 100°C (±5°C), degas, and pack.
Embodiment 1
[0031] Embodiment 1: steel wire rope anti-oxidation wear-resistant surface grease, by weight percentage, its component is as follows: palm wax 12.8%, duroc pine wax 20%, cycloalkyl extract oil 19%, paraffin-based high-viscosity oil 25%, two Zinc alkyl dithiophosphate 3%, diphenylamine 3%, polyisobutylene 10%, ethylene-propylene copolymer 7%, calcium sulfonate 0.2%.
Embodiment 2
[0032] Embodiment 2: steel wire rope anti-oxidation wear-resistant surface grease, by weight percentage, its component is as follows: palm wax 14%, duroc pine wax 19%, cycloalkyl extract oil 17.5%, paraffin base high-viscosity oil 26%, two Zinc alkyl dithiophosphate 5%, diphenylamine 1%, polyisobutylene 8%, ethylene-propylene copolymer 9%, calcium sulfonate 0.5%.

Abstract
An antioxidation and wear-resistant surface protection grease for a steel wire rope, which comprises the following components in percentage by weight: 12%-16% of a palm wax, 17%-20% of a Duroc slack wax, 17%-21% of a cycloalkyl extract oil, 22%-26% of a paraffinic high-viscosity oil, 2%-5% of zinc dialkyl dithiophosphate, 1%-4% of diphenylamine, 6%-10% of polyisobutene, 7%-11% of an ethylene-propylene copolymer and 0.1%-1% of calcium sulfonate. The protection grease has a high kinematic viscosity and a strong adhesion to the surface of a steel rope, and prolongs the service life of the steel wire rope.
Description
technical field [0001] The invention relates to a lubricating protection material that can be synchronized with the steel wire rope and coated on the surface of the steel wire rope to resist oxidation, wear resistance, high temperature loss resistance, good adhesion, water resistance and antirust performance, specifically a steel wire rope Oxygen resistant and wear resistant surface grease. Background technique [0002] During the processing and manufacturing of steel wire ropes, there must be a lubricating material, that is, grease on the surface of steel wire ropes. During the production and processing of steel wire ropes, it is evenly coated on the surface of each steel wire, and then the surface of the whole rope is sealed after the rope is closed. It can be delivered to users with a layer of lipid film of moderate thickness. Because some parts of the steel wire rope lack oil during use, there will be great safety hazards, and it is inconvenient to replenish grease in t...
