Anti-oxidant and wear-resistant surface protection grease for steel wire ropes

Abstract

The invention relates to anti-oxidant and wear-resistant surface protection grease for steel wire ropes. The surface protection grease consists of the following components in percentage by weight: 12-16 percent of palm wax, 17-20 percent of Duroc slack wax, 17-21 percent of naphthenic base extract oil, 22-26 percent of paraffin base high-viscosity oil, 2-5 percent of zinc dialkyl dithiophosphate, 1-4 percent of diphenylamine, 6-10 percent of polyisobutene, 7-11 percent of ethylene-propylene copolymer and 0.1-1 percent of calcium sulfonate. Compared with the prior art, the surface protection grease has the advantages of high dropping point, no softening or drain on hot weather, quick coagulation during coating, no waste of raw materials, no pollution on the operation environment (including use), high moving viscosity, high adhesion to the surfaces of steel ropes, and avoidance of the phenomenon of falling in a strong shocking state at a high temperature during operation. The more outstanding characteristic is that the neutral and weakly acid states of the conventional final products (including imported Elaskon) are turned into a weakly alkaline (NaOH is not more than 0.15 percent) state in which metals can pass a corrosion test. As the formation of acid substances can be neutralized effectively, SH/T0325 oxidation stability test and SH/T0332 corrosion test are passed excellently, the service lives of steel wire ropes are prolonged, and the production, storage and use environments are purified.

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...

AI Technical Summary

Problems solved by technology

[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
