Embodiment 1
[0024] Embodiment 1: a kind of steel wire rope grease, the weight percent of its preparation raw material is:
[0025] 150BS 71%, synthetic hydrocarbon 10%, ozokerite 5%, polyethylene 6%, phenolic resin 3%, chlorinated paraffin 2%, petroleum barium sulfonate 2%, MCA 1%. Its preparation method is as follows:
[0026] 1) Preheat 2 / 3 of the base oil to 70-90°C in advance, and start the stirring device at the same time to make it evenly heated;
[0027] 2) When the temperature is between 80 and 100°C, add thickener and polymer adhesive in batches in sequence, and stir until completely dissolved;
[0028] 3) Continue heating to 120-140°C and stir for 20-40 minutes to remove trace moisture in the raw materials;
[0029] 4) Add the remaining amount of base oil, and when it is cooled to 90-110°C, add various additives in batches and stir evenly;
[0030] 5) After cooling, the finished product can be obtained after sampling and testing are qualified.

Abstract
The invention relates to steel rope grease with high dropping point and a preparation method of the steel rope grease. The steel rope grease with high dropping point comprises the following compositions in percentage by weight: 65%-85% of base oil, 5%-20% of thickening agent, 2%-15% of adhesion agent, 1%-6% of rust inhibitor, 0-5% of antioxidant, 0-5% of polar additive and 0.5%-6% of solid lubricant. According to the steel rope grease, the dropping point of the steel rope grease is high (no less than 100 DEG C), the adhesion property is good (a slump test is qualified), the low temperature performance is good, superior adhesion property and oil film forming capacity are realized, and comprehensive performances such as waterproofing, corrosion resistance, oxidation resistance and wear resistance are also realized; and high-quality steel rope grease products required by the imported steel rope products can be partially replaced by the steel rope grease, so that the production cost is reduced for enterprises, the lubrication and corrosion resistant problems of the steel rope can be relieved, and the service life of the steel rope can be greatly prolonged.
Description
technical field [0001] The invention relates to a steel wire rope grease mixture, in particular to a high dropping point steel wire rope grease and a preparation method thereof. Background technique [0002] Steel wire ropes are widely used in tourism, mining, fishery, machinery, transportation and other industries. With the development of my country's economic construction and the adjustment of industrial structure, wire rope users have higher and higher requirements for wire rope grease, which not only requires steel wire rope grease to have good protective properties , It also requires a high dropping point, strong adhesion, and no adverse effects on the surrounding environment. [0003] At present, the domestic ordinary grease is basically based on SH0387-92 steel wire rope surface grease, and the product index can meet the standard requirements, but the product index and performance are still far from foreign advanced products such as Elaskon protective grease.
