Abstract

The invention provides neopentyl polyol ester automobile gear lubricating oil containing sulphurized isobutylene. The neopentyl polyol ester automobile gear lubricating oil is prepared by taking neopentyl polyol ester as basic oil, adding the sulphurized isobutylene with the code of T321, dialkyl pentasulfide with the code of RC2540 and a composition of a phosphorus family with the code of P120, and uniformly mixing. The proportions of the composition are as follows: the weight percents of esters added by taking the neopentyl polyol ester as the basic oil are as follows: 0.05%-0.35% of T321, 0.03%-0.39% of RC2540 and 0.02%-0.32% of P120. The neopentyl polyol ester automobile gear lubricating oil containing the sulphurized isobutylene has very good extreme pressure abrasion resistance and the bearing capability is up to 3361N; the minimum grinding crack value is shown in description. The neopentyl polyol ester automobile gear lubricating oil can be used for preparing heavy-load vehicle gear oil and can also be used for heavy-load and middle-load industrial gear oil.

Description

technical field [0001] The invention relates to the technology of gear lubricating oil, in particular to a neopentyl polyol ester automotive gear lubricating oil containing sulfur thinner. Background technique [0002] Sulfurized isobutylene Sulfurized isobutylene, T321 has a high sulfur content and has better extreme pressure and anti-wear properties than general sulfide products. Very low chlorine content. T321 is the preferred extreme pressure and anti-wear agent for vehicles and industrial oils. It has excellent extreme pressure and anti-wear properties and high load-carrying capacity. It is mainly used to configure heavy-duty vehicle gear oil, and can also be used for heavy-duty and medium-duty industrial gear oil. Phosphorus Star P120 is an alkyl phosphate produced by the reaction of low-carbon alcohols and phosphorus oxychloride, and then reacted with organic amines and phosphate esters. Due to the small alkyl group of the organic amine and the high extreme pressur...
