[0005] The Chinese invention patent applications with publication numbers CN10351576A, CN103497815A and CN103923728A respectively disclose anti-wear and energy-saving lubricating oils. In the above-mentioned applications, oil-soluble organic molybdenum salts are used to reduce the friction coefficient so as to achieve the purpose of energy saving. The defect is: organic molybdenum Salt only generates antifriction substances after chemical reaction at high temperature and then adsorbs on the metal surface, thereby producing antifriction effect. At low temperature, the antifriction ability is weak, and with the extension of oil use time, organic molybdenum and oil oxidation will produce The reaction of peroxide will lead to the gradual decrease of effective molybdenum content, increase of frictional resistance and increase of fuel consumption
[0006] The publication number is CN101481638A Chinese invention patent application has proposed a kind of energy-saving and emission-reducing heavy truck special nano-anti-wear lubricating oil and its production method. This patent is mainly aimed at heavy-duty diesel engines, and the viscosity of the oil is high. In the state of fluid lubrication, fuel consumption will be increased instead, and there is no comprehensive energy-saving effect

Embodiment 1

[0024] The mixed base oil and the mass percentage of 60% polyalphaolefin synthetic base oil and 20% ester oil and 20% additives are weighed, and the additives include a viscosity index improver, a pour point depressant, an extreme pressure Agent, cleaning agent, anti-oxidant anti-corrosion anti-rust agent, anti-friction and anti-wear synergist, antifoaming agent, according to the lubricating oil composition of energy saving and emission reduction described in claim 1, wherein poly-alpha olefin or polymethacrylic acid Methyl ester, whose content is 5% by weight of the composition, calcium sulfonate or calcium salicylate, whose content is 3% by weight of the composition, boric acid fatty ester amine salt, whose content is 3% by weight of the composition 0.5% (by boron weight). Benzotriazole dodecylamine salt, its content is 5% that accounts for composition mass percent.

Embodiment 2

[0028] Preparation method Add the base oil into the blending kettle according to the metered quantity, start stirring, raise the temperature to 65-70 degrees Celsius, add the quantities of each component to the base oil in the following order, first add the pour point depressant, and the second add Viscosity index improver, followed by adding extreme pressure agent, detergent, anti-oxidation, anti-corrosion and anti-rust agent, anti-friction and anti-wear synergist, anti-foaming agent. After adding all the components, keep the original temperature and continue to stir for 30 minutes. After all the components are mixed evenly, cool down to room temperature to obtain a homogeneous, light brown, clear and transparent lubricating oil.

Abstract

The invention provides an energy-saving emission-reducing lubricant composition, made from, by weight, 80-90% of basic oil and 10-20% of additives; the additives include a viscosity index modifier, a pour point depressant, a clearing agent, an extreme pressure agent, an antioxidant anticorrosion antirust agent, an antifriction wear-resistant synergist, and a defoaming agent; the energy-saving emission-reducing lubricant composition is low in friction efficient and good in antifriction synergic effect, and has significant energy-saving and emission-reducing effects.

Description

technical field [0001] The invention relates to a lubricant, in particular to an energy-saving and emission-reducing lubricating oil composition. Background technique [0002] At present, due to the increase in the number of automobiles, work efficiency and living standards have been improved, but their energy consumption and exhaust emissions are also very alarming to the environment. In order to cope with environmental problems such as reduction of carbon dioxide emissions, energy saving, that is, fuel saving in automobiles and construction or agricultural machinery has become an urgent need, and devices such as engines, transmissions, final drive reducers, compressors or oil hydraulic power units are strongly required to save energy . Therefore, lubricating oils used in these systems need to reduce agitation resistance and friction resistance more than before. [0003] The cost of improving fuel economy through lubricating oil formulation technology is much lower than o...
