Problems solved by technology

Although oil-based oils have good lubricity, they will oxidize and volatilize seriously at a high temperature of 300°C, and the oil will smoke seriously, and fires may occur, which not only pollute the environment, but also endanger the safe use of equipment.
Pure water-based tire agent has a fast volatilization speed at high temperature, no flash point, no smoke, but it is difficult to ensure continuous and effective lubrication
[0005] With the increasing emphasis on environmental protection and energy conservation worldwide, the widely used oil-based tire tires have the disadvantages of poor biodegradability and environmental pollution, and are facing the severe test of environmental requirements, while the water-based lubricant products The lubricating performance cannot reach a satisfactory level; therefore, the development of environmentally friendly, high temperature resistant, good lubricating performance and safe use of tire tire products has become a new development direction

Abstract

The invention provides a preparation method of a water-soluble nanometer high-temperature super lubricant for a wheel belt. The preparation method comprises the following steps: firstly, preparing a sandwich-structure solid additive MoS2 / graphene / MoS2 and a water-based bio-based bactericide carbon nanotube / lysozyme; preparing an oil-phase mixed solution and a water-phase solution, namely sequentially adding a lubricant, an emulsifier and an oily bactericide into base oil, conducting full stirring at 50-60 DEG C to obtain the oil-phase mixed solution, sequentially adding an anti-corrosion and anti-rust agent and a waterborne bio-based bactericide carbon nanotube / lysozyme into water, and conducting full dissolving to obtain a water-phase solution; then, adding the water-phase solution into the oil-phase mixed solution, and carrying out uniform stirring to obtain an emulsion; then, adding the sandwich-structure solid additive MoS2 / graphene / MoS2 into the emulsion, and performing stirring to obtain a colloid mixture; and finally, homogenizing the colloid mixture in a three-roller ball mill 2-3 times to obtain the water-soluble nanometer high-temperature super lubricant for the wheel belt. With the water-soluble nanometer high-temperature super lubricant, relative friction between the wheel belt and a base plate can be reduced, the service life of equipment is prolonged, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a preparation method of a water-soluble nano-tire high-temperature super lubricant. Background technique [0002] At present, in the rotary kiln in the cement industry, high-temperature equipment in steel and chemical industries, lubrication technology is a key link in production; the development of lubricants restricts the development of the industry. Taking the rotary kiln as an example, the rotary kiln is the key equipment for cement plant production. It rotates through gears, and there are three sets of support wheels and tire belts in the middle to make a rotary motion; the backing plate is a strip support arranged in an arc-shaped gap between the rotary kiln body and the tire belt, and it plays a role in cooling the cylinder. And tires, transmission torque and facilitate the role of tire installation. [0003] The tires of the rotary kiln play the role of supporting th...
