Long-acting steel wire rope hemp core grease

Abstract

The invention provides long-acting steel wire rope hemp core grease. The long-acting steel wire rope hemp core grease is prepared from the following components in parts by weight: 13 to 17 percent ofpalm wax, 16 to 19 percent of microcrystalline wax, 15 to 19 percent of naphthenic high-viscosity oil, 24 to 28 percent of paraffin-based high-viscosity oil, 1.6 to 4.6 percent of zinc dialkyl dithiophosphate, 1.4 to 4.4 percent of nonyldiphenylamine, 4.5 to 8.5 percent of ethylene acetic acid, 8.5 to 12.5 percent of polyisobutene and 0.1 to 1 percent of calcium sulfonate. The invention also provides a preparation method of the long-acting steel wire rope hemp core grease. The preparation method comprises the following steps: S1) putting naphthenic high-viscosity oil and paraffin-based high-viscosity oil into a reaction tank, heating to 130-140 DEG C, stirring for 30 minutes, and dehydrating to obtain a first prefabricated material; and S2) successively adding palm wax, microcrystalline wax, nonyldiphenylamine, ethylene acetic acid and polyisobutene into the first prefabricated material. The long-acting steel wire rope hemp core grease is high in dropping point, high in kinematic viscosity and capable of inhibiting free acidic bodies generated by oxidation and neutralization so that a steel wire rope is not liable to rust, and the service life of the steel wire rope can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of lubricating and protecting materials, in particular to a long-acting steel wire rope hemp core grease. Background technique [0002] During the processing of the steel wire rope with a hemp core, the hemp core rope must be soaked in the protective grease that has been heated and melted, and it can be used after it has been fully soaked for a specified time. Otherwise, the metal surface of the inner wall will be damaged during the working period of the steel wire rope. Without the protection and lubrication of a good performance grease film, it will cause corrosion, shorten the life, fail to achieve safe production, and be prone to accidents. Even if it is found that there is a lack of protection, it is difficult to replenish it. Long-term and safe operation can only be achieved with high-quality lubricating and protective materials. The quality of the wire rope is mainly determined by the performance and ...

[0002] During the processing of the steel wire rope with a hemp core, the hemp core rope must be soaked in the protective grease that has been heated and melted, and it can be used after it has been fully soaked for a specified time. Otherwise, the metal surface of the inner wall will be damaged during the working period of the steel wire rope. Without the protection and lubrication of a good performance grease film, it will cause corrosion, shorten the life, fail to achieve safe production, and be prone to accidents. Even if it is found that there is a lack of protection, it is difficult to replenish it. Long-term and safe operation can only be achieved with high-quality lubricating and protective materials. The quality of the wire rope is mainly determined by the performance and infiltration quality of the core grease. At present, the drop point of the core grease commonly used in the domestic market is low. When used in hot summer, it is easy to cause temperature rise due to high-speed heavy-load friction, and it is easy to flow, resulting in oil shortage and pollution. At the same time, the kinematic viscosity of the existing steel wire rope hemp core grease is low, which is generally about 30 on the market. It is easy to leak and flow, lacks protection, and has little adhesion, and because the hemp core resin is generally neutral or weakly acidic, it cannot inhibit the free acidic body produced by oxidation and neutralization, and it is easy to rust the steel wire rope in advance, reducing the The service life of the wire rope
