Abstract

The invention discloses lubricating oil capable of remarkably reducing engine noise and a preparation method thereof, and belongs to the technical field of lubricating oil and additives. The lubricating oil is composed of the following components: 6-12% of a gasoline engine oil complexing agent; 5-15% of a viscosity index improver; 0.1-1% of a friction reducing agent; 0.1-0.5% of a pour point depressant; 38%-45% of base oil A; and 35-40% of base oil B. The preparation method comprises the following steps: sequentially adding the components into a blending kettle according to the high-low sequence, heating to 50-60 DEG C, heating and stirring for 2 hours, uniformly mixing, filtering while hot, and cooling to room temperature to obtain the product. By optimizing component selection, proportion and preparation process, the obtained lubricating oil has excellent wear resistance, cleaning and dispersing performance, high-temperature oxidation resistance and the like, can remarkably reduce the working noise of an engine, and is beneficial to improving the driving feeling of people.

Description

technical field [0001] The invention belongs to the technical field of industrial lubricating oil and additives, and more specifically relates to a lubricating oil which significantly reduces engine noise and a preparation method thereof. Background technique [0002] In the current development of the automobile industry, there are many metal surfaces in the engine that rub against each other. Especially for new cars leaving the factory or old cars after engine overhaul, if the fit clearance of each part is uneven or too tight, running-in adjustment is required, and lubricating oil is often used. Lubricating oil is a liquid or semi-solid used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. It generally consists of base oil and additives. Base oil is the main component of lubricating oil and determines th...
