example 1

[0021] Put 750g of soybean oil into the kettle, add 180g of tallow and 50g of hydrogenated oil (obtained by hydrogenation of tallow), heat up and stir, when the temperature rises to 140-150°C, keep stirring at the temperature for 20-30 minutes, stop heating, when When the temperature drops to 125-130°C, add 20g of lanolin additive, stir evenly, and leave the kettle. The composition and performance tests are shown in Table 1.

example 2

[0023] Put 670g of soybean oil into the kettle, add 280g of tallow, 20g of hydrogenated oil (obtained by hydrogenation of castor oil), heat up and stir, when the temperature rises to 140-150°C, keep the temperature and stir for 20-30 minutes, stop heating, when When the temperature drops to 125-130°C, add 30g of lanolin additive, stir evenly, and leave the kettle. The composition and performance tests are shown in Table 1.

Abstract

A kind of grease lubricant used to protect tightwire, the weight content basing on the whole weight of the compound of each component is as following: (1) the proportion of the animal fat is 10-50%. (2) The proportion of hydrogenated oil is 1-10%. (3) The proportion of the wool grease rust-preventing agent is 0.5-8%. (4) Vgetable oil remainder. The hydrogenated oil of above is produced by hydrotreating of the animal oil, and the molecular weight of it is 850-890.The melting point of the wool oil is 38-42DEG C, and the iodine value of it is 18-36. The fat in this invention is kind of grease lubricant used to protect the tightwire which is friendly to the environment, and independent to petroleum raw material, and the biological degradation property of it is very good. It can be smeared on the surface of the tightwire during the process of it, or the hemp center can be dipped in it, it can prevent the rust-eaten of the tightwire, and also can act as a lubricant. The dropping point of the grease lubricant is more than 65DEG C, and it can resolve the problem that the dropping point of the hydrocarbon-based grease lubricant is too low.

Description

technical field [0001] The invention belongs to a grease composition, in particular to an antirust grease for metal parts, steel wire ropes and rope cores. technical background [0002] At present, hydrocarbon-based lubricating grease is mainly made of petroleum fat thickeners, namely ozokerite, paraffin and wax paste thickened with high-viscosity mineral oil and added with antirust agents. This product has been used for many years and is still widely used. Its advantages are cheap price and good antirust performance. But its disadvantage is that the dropping point is low, generally 58°C, and there is a problem of poor high temperature and cold resistance, which needs to be improved. Metal specimens and steel ropes using this product will be seriously lost in direct sunlight in summer, resulting in loss of protection and environmental pollution. [0003] The techniques for improving the dropping point of hydrocarbon-based grease include adding polyolefin, fatty acid salt, ...
