Problems solved by technology

However, the high temperature resistance and water resistance of this grease are not enough. The preparation method of this patent is to compound calcium sulfonate and then compound titanium, and the reaction is not easy to control. Moreover, the conventional water addition reaction is difficult to control the grease formation, and there is also a reaction time that is too long. long wait question
The defects of the above preparation method will further affect the performance of the grease
[0005] In short, the high temperature resistance and water spray resistance of the grease in the prior art are still not enough. For example, when the continuous casting machine and roll bearing in the steel plant are used for a long time, problems such as high temperature coking and blockage of centralized lubrication pipelines are prone to occur.

Abstract

The invention relates to complex titanium and calcium sulfonate lubricating grease and a preparation method thereof. The complex titanium and calcium sulfonate lubricating grease comprises the following components in percentage by weight: 70-80 percent of base oil, 17-24 percent of a complex titanium and calcium sulfonate soap thickener, 2-4 parts of a high-temperature thermal-stability improving agent and 1-2 percent of an antioxidant. By introducing a solvent and the base oil in the preparation method, an reaction interface is added, the reaction rate and the extent of reaction are improved, the preparation time is greatly shortened, the thickening capability of complex titanium and calcium sulfonate soap is improved, and at the same time the composite production process is optimized. The product quality is good in stability. The complex titanium and calcium sulfonate lubricating grease has a good extreme pressure anti-wear property and long lubrication life, can be used for a long term at a high temperature of 200 DEG C, and also has a good effect of reducing noises.

Description

technical field [0001] The invention relates to lubricating grease and a preparation method thereof, in particular to a composite calcium titanium sulfonate lubricating grease and a preparation method thereof. Background technique [0002] Although transition metals are widely distributed in nature, and transition metal organic compounds have been widely used, there are few studies on greases prepared with fatty acid soaps prepared from transition metals as thickeners. In 1961, Markley prepared titanium stearate soap, but the dropping point was only 62°C, so it was not used as a thickener for grease. Until the 1990s, Indian researchers successfully developed high-performance, multi-functional composite titanium-based grease. Studies from the perspective of toxicity and safety have shown that composite titanium-based grease is safe for both producers and users, and the composite titanium-based grease prepared from vegetable oil has good biodegradability. From the perspective...
