Abrasion-resistant, anti-drag and damaged surface repair agent for metal and preparation method thereof

Abstract

The invention belongs to the field of repair agents for surface of metal and in particular relates to an abrasion-resistant, anti-drag and damaged surface repair agent for metal and a preparation method thereof. The repair agent includes, by mass, 2-40% of abrasion-resistant repair powder, 45-95% of lubricating oil and 3-20% of random polyether, and a hexahydric composite emulsifier can also be added, wherein the abrasion-resistant repair powder comprises, by mass, 5-35% of organic molybdenum, 20-60% of lanthanum fluoride, 2-28% of nickel powder, 5-30% of silicon dioxide powder and 3-15% of boron nitride powder. The preparation method includes grinding the lubricating oil, the abrasion-resistant repair powder and the random polyether according to the ratio after even mixing, adding the hexahydric composite emulsifier, and evenly mixing to obtain the repair agent. According to the repair agent, abrasion due to friction can be reduced, the repair function of damaged surfaces is provided, using accuracy and reliability of equipment can be improved, energy and electricity can be saved, and the service life of the equipment can be prolonged.

Description

technical field [0001] The invention belongs to the field of metal surface repairing agents, in particular to a metal wear-resistant, drag-reducing and damaged surface repairing agent and a preparation method thereof. Background technique [0002] Friction and wear is an inevitable phenomenon in the operation of mechanical equipment. In the operation of mechanical equipment, one-third of the energy is used to overcome frictional resistance. It is the main link of energy consumption. Wear is a sign of the life of mechanical equipment. When the amount of wear exceeds the design requirements of the equipment, it marks the end of the equipment's life. Relevant data show that the economic loss caused by friction and wear in the United States exceeds 200 billion U.S. dollars every year. With the development of our country's economy, it has become a big country of machinery and equipment, and the machinery and equipment manufacturing industry is also developing rapidly. It will a...

Problems solved by technology

[0005] The main problems in the manufacturing process: First, most of the working machines of their own are used for too long, and the precision is greatly lost. The precision of the manufactured parts is affected, and the tolerance of the parts is large, which leads to low precision of my country's mechanical equipment since the factory , short service life and high consumption

The second is that with the extension of the service life of the equipment, the operating parts are worn and corroded, and a large amount of money is spent on the purchase of equipment for maintenance every year. The equipment cannot work with the same accuracy during the maintenance cycle, which affects the quality of the product.

Third, due to the gap in the general assembly level of the machinery and equipment manufacturing industry, it is difficult to achieve a high level of precision of machinery and equipment, and the noise of equipment operation is relatively large.
