Description

A kind of compound additive for engine oil

(1) technical field

The present invention relates to the compound additive of a kind of engine oil, particularly to a kind of answering for engine oil Close preparation scheme and the manufacture method of additive.

(2) background technology

Engine oil almost occupies half lubricating oil market at present, and China's car owning amount in 2013 is More than 100,000,000, thus receive much attention.The major function of engine oil is the prolonged mechanical life-span, Ensure machinery normal operation under the conditions of different rotating speeds, temperature and pressure.At low temperatures, lubricating oil should have Having good mobility so that the lubrication of moving component can be ensured in time, at high temperature, lubricating oil should be preferable Isolation moving component thus reduce abrasion.Lubricating oil is rubbed by minimizing and walks heat from friction surface generation Form plays lubrication, and the pollutant that engine adds up in running just can affect engine Often work, these pollutants are probably particle, greasy filth, carbon deposit, acid or peroxide.The one of lubricating oil Individual very important effect prevents these materials from working the mischief engine exactly.And current each class lubricating oil Additive matter is measured expensive, the poor effect that a lot of prices are low.And along with social progress and people The development of class science and technology, engine oil also must have the biggest development, because present oil drain interval itself It it is exactly great energy waste.And defining of drain period is all decided by, effect of various additives and basis The selection of oil and the science of preparation scheme.If so effect of additive and the selection of base oil and Preparation scheme can more be rationalized, technicalization, first evolve.So oil drain interval of engine lubricating oil is certain Have breakthrough greatly.

(3) summary of the invention

It is an object of the invention to provide one, to prepare scheme more scientific, and preparation method is simple, and price is low, quality In the high use cycle that can extend lubricating oil, improve wear-resistant and anti-extreme pressure, resistance to oxidation, peace and quiet excellent effect, Anti-foaming is remarkably productive, antirust, anti-corrosive, emulsion resistance, and degradable is more environmentally friendly, extends the drain period, waits each Plant effect and all can reach the compound additive for engine oil of good result.
