Problems solved by technology

However, cylinder oil and gear oil are easy to oxidize, emulsify and deteriorate in harsh lubricating environments, and it is difficult to form an effective lubricating film to ensure the normal operation of the tire under high load, high temperature and water spray conditions
Lubricants containing soap base have the defects of poor high temperature resistance and extreme pressure performance. Under the working conditions with a lot of dust, lubricants containing soap base are easy to coke, which makes the tires easy to be in a state of severe wear, which increases the wheel load. Probability of network cracks, spalling, or even fracture
Because the rotary kiln tires are operated in the open air, due to the poor adhesion of asphalt-based and soap-based lubricants at high temperatures, and most of these products use raw materials such as polyalphaolefins and mineral base oils with poor biodegradability, the machine During high-temperature operation, it is easy to cause lubricant to be thrown out, causing pollution to the site environment
[0004] The lubrication problem of the rotary kiln tire has been difficult to solve for a long time. In view of the above situation, a lubricant with high temperature resistance, extreme pressure, anti-wear and high biodegradability is needed to meet the lubrication of the tire and maintain the normal production of the rotary kiln

preparation example Construction

[0042] The present invention also provides a preparation method of the lubricant according to the present invention, comprising the following steps: uniformly mixing the components, and grinding the obtained materials to obtain the lubricant.

[0043] More preferably, include the following steps:

[0044] (1) Pour the base oil into a clean stainless steel blending kettle for heating, heat to 80-100°C, add antioxidant, and stir at a constant temperature of 80-100°C; (2) Cool down, add tackifier, extreme pressure and anti-wear agent, solid additive and dispersant, stir evenly;

[0045] (3) The material in the blending kettle is beaten out, and the lubricant is obtained after being ground by a three-roll mill.

[0046] The heating temperature is preferably 90°C, and the constant temperature stirring temperature is preferably 90°C.

Abstract

The invention provides a lubricant and a preparation method thereof. The lubricant is prepared from the following components by mass percent: (a) 50 to 59 percent of base oil, (b) 10 to 20 percent of a tackifier, (c) 1 to 6 percent of an anti-wear reagent at extreme pressure, (d) 1 to 5 percent of an antioxygen, (e) 20 to 35 percent of a solid additive, and (f) 0.5 to 5 percent of a dispersant. The lubricant has better high-temperature lubrication adhesion, high temperature resistance and extreme pressure antiwear property, and is specially suitable for lubrication of a high temperature tyre.

Description

technical field [0001] The invention relates to a lubricant and a preparation method thereof, in particular to a lubricant applied to high-temperature tires of cement rotary kilns and metallurgical chemical rotary kilns and a preparation method thereof. Background technique [0002] Rotary kiln is the key equipment in cement, chemical industry, metallurgy and other industries. It is characterized by high temperature, heavy load, high dust, humidity, open-air operation, and long-term operation under harsh environmental conditions. With the enlargement of the rotary kiln and the increase of production capacity, the pressure on the tire belt and related components also increases, so the requirements for lubricants are also getting higher and higher. There are still few special lubricants for rotary kiln tires and related parts, the main reason is that the amount of this type is small and has not attracted enough attention from oil product manufacturers. [0003] At present, th...
