Abstract

The invention discloses lubricating oil for rotary kiln wheel belts and a method for preparing the same. The lubricating oil can be used to solve the problem that the lubricating performance of the rotary kiln wheel belts is undesirable in severe environments, has high wear resistance and high temperature resistance. The maximum use temperature of the lubricating oil can reach 600 DEG C, and therefore the lubricating oil can form a high-strength high-temperature protective lubricating firm to prevent vibration, distortion and deformation of rotary kilns and falling of flame-retarding bricks and to prolong the service life of the rotary kilns. The easy method for preparing the lubricating oil can improve working efficiency and product quality obviously and save lots of energy, and is convenient to promote. The lubricating oil for rotary kiln wheel belts comprises the following components in percentage by mass: 49 to 69 percent of poly-alpha-olefin, 10 to 30 percent of composite calcium-base grease, 10 to 40 percent of composite metal soap, 2 to 5 percent of nano colloidal molybdenum disulfide powder, 2 to 4 percent of colloidal graphite powder, 1.5 to 3 percent nano soft metal powder and 5 to 6 percent of flame retarder, wherein the total percentage of the components is 100 percent. The kinematic viscosity of poly-alpha-olefin synthetic oil at 100 DEG C is 40 to 80 centistokes, and the open flash point of the poly-alpha-olefin synthetic oil is not less than 320 DEG C.

Description

technical field [0001] The invention relates to lubricating oil, in particular to a rotary kiln tire lubricating oil and a manufacturing method thereof. Background technique [0002] At present, my country's cement industry is developing rapidly and changing with each passing day. In particular, new dry process production lines of 5000t / d and above have been built, and more than 100 projects are under construction. Production lines of 5000t / d and above have heavy loads and harsh operating conditions. The tires and related components (backing plates, supporting rollers, retaining rings, retaining wheels, etc.) are under high pressure, and ordinary lubricating grease cannot achieve optimal lubrication. state. There are still few special lubricants for rotary kiln tires and related parts, and they mainly rely on imports. The imported products are expensive. The main reason is that the amount of this type of lubricant is small and cannot attract the attention of oil manufacture...
