Abstract

The invention relates to a wire rope lubricating grease composition having dual effects of lubrication and anti-corrosion. The composition comprises the following components: 51.0 % to 72.5 % of No. 2 composite calcium sulfonate grease, 25.0 to 38.0 % of low-freezing-point base oil, 0.2 to 1.0 % of diphenylamine, 1.3 to 5.5 % of colloidal graphite and 1.0 to 4.5 % of ozocerite. According to the invention, the composite uses the specific composite calcium sulfonate grease as a base oil, and is added with the low-freezing-point base oil and various additives to further improve performance such as low-temperature resistance, anti-oxidation, wear resistance, and water resistance of the product, so that the wire rope lubricating grease having dual effects of lubrication and anti-corrosion can be obtained. The lubricating grease has dual effects of lubrication and anti-corrosion, and can delay corrosion and wearing speed of the wire rope. The product is suitable for lubrication and protection of various wire ropes under ocean climate conditions such as seaport, marine ship, offshore drilling platforms, etc.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a steel wire rope grease composition with dual functions of lubricating and antirust. Background technique [0002] In marine climate conditions, various corrosion problems can be caused to various metal parts. Especially for marine operating environments such as seaports, shipping ships, and offshore drilling platforms, the corrosion problem of steel wire ropes used in various lifting or traction machinery is more prominent due to long-term exposure. Most of the failure modes of wire ropes working in this environment are two types of wear and corrosion. The waste of steel wire ropes due to wear and corrosion is staggering. The survey shows that due to serious corrosion, a set of ropes will be replaced every 2 to 3 months. Compared with the relatively dry climate on land, marine climate conditions will significantly accelerate the degree and speed of ele...
