Preparation raw materials and method of antiwear protective agent of engine

Abstract

The invention discloses preparation raw materials and a method of an antiwear protective agent of an engine. The preparation raw materials comprise the following materials in parts by mass: 50-100 parts of lubricating oil, 10-20 parts of chlorinated paraffin, 5-10 parts of dibutyl phosphate, 5-10 parts of vulcanized oil, 2-5 parts of alkenyl succinic acid, and 2-5 parts of petroleum calcium sulfonate. The prepared protective agent has the advantages that (1) a firm lubrication protective film capable of bearing high temperature and high pressure can be formed on the frictional surface, the friction coefficient is small and the extreme pressure property is high; (2) due to the added anti-corrosion material, the corrosion of an extreme-press antiwear powder dispersion product can be prevented; (3) after being practically applied to the surface on site, the protective agent can reduce the afterburnt and engine oil consumption, the wear of an air cylinder can be reduced, the airtightness of the air cylinder can be enhanced, the overhaul period of vehicles can be prolonged, the starting and acceleration can be improved, noise can be reduced, the emission of black smoke can be eliminated, and the environmental pollution can be reduced; (4) after the protective agent is added in engine oil of the engine, a layer of film can be formed on the frictional surface, so that the friction can be reduced, the direct contact with metal can be prevented, and further the friction damage can be decreased.

Description

technical field [0001] The invention relates to an automobile engine protective agent, in particular to a preparation material and method of an engine anti-wear protective agent. Background technique [0002] The engine is only under the protection of lubricating oil. The surface looks smooth, but after zooming in, many traces of wear and tear can be found. Therefore, the lubricating oil cannot be replaced only. When the conditions are ripe, the engine needs to be given additional protection, and the engine has been used for a long time. Its power and fuel consumption will gradually increase, and the quality of exhaust emissions will gradually decrease, which will increase pollution to the environment and directly affect people's living environment. According to incomplete statistics, 70% of engine failures are caused by wear, and more than 30% of energy consumption is caused by friction. The lubrication technology that can protect the engine well and maximize the potential ...
