Problems solved by technology

[0004] 1. Low dropping point (SH / T0388 standard: 45-55°C), temperature rise caused by hot summer and high-speed, heavy-load friction, plus the standard stipulated kinematic viscosity > 25, easy to flow, resulting in oil shortage and pollution
[0005] 2. Low kinematic viscosity (SH / T0388 standard > 25) is generally around 30 (equivalent to high-viscosity lubricating oil) in the market. When the temperature rises slightly, it is easy to seep, flow, and lack protection
Unable to inhibit the free acidic body produced by oxidation and neutralization, and rust in advance

Abstract

The invention relates to a long-acting wire rope hemp core grease. The long-acting wire rope hemp core grease comprises 13-17wt% of palm wax, 16-19wt% of microcrystalline wax, 15-19wt% of naphthenic high-viscosity oil, 24-28wt% of paraffinic high-viscosity oil, 1.6-4.6wt% of zinc dialkyl dithiophosphate, 1.4-4.4wt% of nonyldiphenylamine, 4.5-8.5wt% of vinylacetic acid, 8.5-12.5wt% of polyisobutylene and 0.1-1wt% of calcium sulfonate. Compared with hemp core greases in the prior art, the long-acting wire rope hemp core grease has the advantages of high dropping point, no flowing in hot weather, fast online solidification after rope immersion, no loss, energy saving, no pollution to environment, large kinematic viscosity data, good adhesiveness, and realization of good fluidity and no flowing of a grease film in the motion and compressed processes. Prominently, the property of traditional hemp core greases (including imported hemp core greases) is changed to become weakly alkaline (the free base value is not greater than 0.15, NaOH%), so oxidation is effectively inhibited, generated free acids are neutralized, SH / T0325 oxidation stability test and SH / T0331 corrosion test are extremely well passed, the safe service life of a wire rope is effectively prolonged, and use environment is purified.

Description

technical field [0001] The invention relates to a lubricating and protecting material which is synchronous with steel wire rope, anti-oxidation and anti-corrosion, works in the range of less than 65°C and can provide oil film without loss or slipping, and has good adhesion, water resistance and reversibility, specifically a long-term Efficient wire rope hemp core grease. Background technique [0002] During the processing of the steel wire rope with hemp core, the hemp core rope must be soaked in the protective grease that has been heated and melted, and it can be used only after it is fully soaked for a specified time. Otherwise, during the working period of the steel wire rope, the metal surface of the inner wall cannot be protected and lubricated by a good grease film, which will cause corrosion, shorten the service life, fail to achieve safe production, and cause accidents. Even if a lack of protection is found, it is difficult to replenish. Therefore, it is necessary ...
