Problems solved by technology
The data shows that the nano-metal lubricating oil additives sold in the market are usually inorganic nanoparticles with a particle size of more than 100nm. Poor, easy to agglomerate, precipitate, unable to exert the special anti-wear effect of nano-metal anti-wear materials, and the effect of anti-wear and anti-friction is poor, so the use of global anti-wear agent products is still at a low-tech level and low-efficiency stage
In China, due to the lack of breakthroughs in key technologies for energy conservation and emission reduction, poor investment returns and waste of funds are often caused by the advancement and maturity of technologies.
There are some inconveniences in the use of commercially available nano antiwear agents in lubricating oil
Inorganic type: poor compatibility with lubricating oil, long-term use is easy to form sludge, resulting in clogging of precision filters, which in turn causes equipment wear
Polymer particle type: the compatibility with lubricating oil is also poor, it is easy to block the precision filter, and it is easy to deteriorate under the long-term action of high temperature and high pressure
Strong corrosive chemical formulation with strong extreme pressure: Although the extreme pressure is strong, it is easy to form inorganic acid or other acids with the water in the oil, causing engine corrosion

Abstract
A disclosed nanometer running-in agent is composed of the following compositions in percent by weight: 10-20 parts of heavy alkyl benzene, 10-20 parts of alkyl naphthalene, 20-50 parts of boronized polyisobutylene succinimide, 20-40 parts of molybdenum dialkyldithiophosphate, 1-2 parts of oil-modified phenolic resin, 1-4 parts of hydroxyl silicone oil emulsion 305, 1-4 parts of beef tallow, and 1-4 parts of detergent LD-1. The agent is prepared according to the following steps: (1) putting heavy alkyl benzene into a blending kettle, heating to 60 DEG C, and stirring for 30 min; (2) then adding boronized polyisobutylene succinimide, and continuing to stir for 30 min; (3) then adding molybdenum dialkyldithiophosphate, cyclically stirring for 120 min, then adding oil-modified phenolic resin, hydroxyl silicone oil emulsion 305, beef tallow and the detergent LD-1, keeping a constant temperature of 60 DEG C for 60 min, and then slowly cooling to 40 DEG C or less, loading a barrel, and capping, so as to obtain the agent. Compared with the prior art, the agent possesses the substantial advantages that the agent is applicable to lubrication systems of various vehicles, ships, petroleum chemical machinery, mine machinery and other large-scale equipment, and possesses multiple functions of reducing wear, reducing oil consumption, restoring wear surface, improving bearing capability, reducing noise and the like.
Description
technical field [0001] The invention relates to a running-in agent or an anti-wear agent for an engine, in particular to a nano-running agent. Background technique [0002] According to the data reported by the Chinese Academy of Engineering "Research on the Current Situation and Development Strategy of Tribology Science and Engineering Application": one-third of the world's annual total energy application is consumed in friction loss, and 70%-80% of mechanical parts are due to friction and wear. And failure to scrap. In terms of energy consumption, my country has become the third largest energy consumer in the world, and its energy utilization rate is only 32%, which is much lower than that of developed countries. Low efficiency and high proportion of consumption seriously restrict the growth of my country's corporate and social benefits. Therefore, under the severe situation that the world is facing increasing resource, energy and environmental problems, the research and...
