Abstract

The invention discloses a machine preparation method of high-temperature lubricating grease for kiln cars, which is prepared by adding the following components in parts by weight: 20-50 parts of base oil A; 20-30 parts of base oil B; 5-10 parts of ethylene glycol 10-20 parts of polyabbietic acid; 5-10 parts of polyamine; 1-5 parts of antioxidant; 1-5 parts of rust inhibitor; 1-5 parts of extreme pressure and anti-wear agent. By adding oxidized castor oil and prepared rosin derivatives, the effect of high temperature resistance is achieved, and the viscosity of the lubricant is increased at the same time to enhance its wear resistance.

Description

technical field [0001] The invention relates to a high-temperature lubricating grease for kiln cars and a preparation method thereof, belonging to the technical field of lubricating grease. Background technique [0002] The kiln car refers to the transportation equipment of the tunnel kiln. The working temperature of the kiln car is relatively high, and it must withstand repeated changes in temperature. Therefore, the kiln car should have sufficient strength and heat resistance. The kiln car is mainly composed of a frame, a wheel set and a skirt plate. The grease plays an important role in the connection between the components of the kiln car and the movement of the components themselves. Once the kiln car bearing is stuck due to poor lubrication of the kiln car Death and other problems will cause significant losses to production. At the same time, in the process of using kiln cars, not only the high temperature resistance of lubricating grease is required, but also oxidati...
