Problems solved by technology

[0003] The most cutting-edge technology product in the world: gasoline additive-polyetheramine, its effect is only to clean the IVD of the intake valve deposits of automobile engines, and has a certain effect on reducing emissions and saving fuel on gasoline vehicles, but the effect is not ideal
[0004] At present, the commonly used lubricating oil and its additives have the following defects: 1) odorous, toxic, corrosive, and non-biodegradable; A high proportion of phosphorus, sulfur, and chloride, among which phosphorus, sulfur, and chlorine have many disadvantages in terms of environmental protection and metal damage, especially phosphorus can cause rapid poisoning of automobile three-way catalytic converters; 3) The adsorption film or reaction formed by the friction pair Membranes are not only fragile, but also consumable, corrosive to metals, and one of the contributing factors to automobile exhaust

Embodiment 1

[0035] This embodiment relates to a phosphorus-free, sulfur-free, chlorine-free and ash-free lubricating oil, and the specific preparation includes the following steps:

[0036] 1.1 Preparation of hydroxystearic acid / ricinoleic acid neopentyl polyol synthetic complex ester

[0037] R-O-SO 3 H (R is a C20 straight-chain alkyl) as a catalyst, in the presence of nitrogen, in the presence of an emulsifier, a mixture of hydroxystearic acid and ricinoleic acid, and pentaerythritol as a reaction raw material, the molar ratio of acid to alcohol 3: 1, the amount of catalyst is 0.1% of the total mass of the reaction material, polyol: emulsifier molar ratio is about 1: 0.01, under the condition of 60 ℃, the water is cut off, and the esterification reaction is distilled for 48 hours to remove untreated The reacted fatty acid is the product of polyalcohol synthesis complex ester. This esterification reaction is carried out in a batch type reactor. The emulsifier is a random copolymer of...

Embodiment 2

[0042]This embodiment relates to a phosphorus-free, sulfur-free, chlorine-free and ash-free lubricating oil, and the specific preparation includes the following steps:

[0043] 2.1 Preparation of hydroxystearic acid / ricinoleic acid neopentyl polyol synthetic compound ester

Abstract

The invention discloses non-phosphorus sulfur-free chloride-free ashless lubricating oil which comprises the following components in percentage by weight: 15-55% of neopentyl polyol compound duplicate-ester hydroxystearate / ricinoleate, 15-50% of a hydropolymer of C10-30 linear olefin, 0.1-15% of ethoxylated amine, 0.1-15% of octyl butyl diphenylamine and 0.1-15% of an ester group containing thiadiazole derivative, wherein the neopentyl polyol compound duplicate-ester hydroxystearate / ricinoleate is prepared by carrying out an esterification reaction on a mixture of hydroxy stearic acid and ricinoleic acid and a neopentyl polyol polymer in the presence of nitrogen, an emulsifier and a catalyst. The lubricating oil disclosed by the invention can be added into a sump as an additive, and can be used for reducing emission of pollutants in automobile exhaust gases by about 50-75%, protecting a three-way catalyst of an automobile and delaying at least one time of poisoning time of the three-way catalyst.

Description

technical field [0001] The invention relates to an additive for energy-saving gasoline, in particular to a phosphorus-free, sulfur-free, chlorine-free and ash-free lubricating oil. Background technique [0002] In order to make up for the quality problems of gasoline itself and the shortcomings of the mechanical manufacturing limit of motor vehicles, gasoline additives are usually added to gasoline; so that the gasoline engine can overcome the cold shock effect and gap effect, and remove the carbon deposits on the intake valve and electric nozzle ; It also enables gasoline engine vehicles to protect the engine working conditions and achieve more complete combustion of fuel, thereby achieving the effects of eliminating carbon deposits, saving fuel, reducing emissions, and enhancing power. [0003] The most cutting-edge technology product in the world: gasoline additive-polyetheramine, its effect is only to clean the IVD of the intake valve deposit of the automobile engine, an...
