Problems solved by technology

However, people are still using gasoline lubricating oil, and the substances produced after methanol gasoline combustion are essentially different from those produced after gasoline combustion. The emissions of formic acid, acetic acid and other acidic substances produced during the combustion of methanol gasoline (M85) fuel substances are harmful to the three-way catalytic converter

Embodiment 1

[0025] A kind of preparation method of lubricating oil is characterized in that, comprises the following steps:

[0026] (1) In the reaction kettle, add 93 parts of machine oil above SH grade, 0.1 part of potassium isooctanoate, 0.1 part of sodium ricinoleate, 1.0 part of alkyl calcium salicylate, alkyl thio 1.5 parts of phosphate, 3.7 parts of polybutylene succinimide, stirring while heating and keeping the temperature at about 55°C;

[0027] (2) After it is all mixed evenly, filter through a mucus filter;

[0028] (3) Test against the national standard, and if there is any deficiency, add viscosity modifier, pour point depressant, antifoaming agent and other additives to adjust to the national standard. Additives include viscosity improver (ethylene propylene copolymer (OCP) viscosity index improver Bohuihua Chemical Co., Ltd.) 0.3 parts, pour point depressant (polyα-olefin) 0.1 part, antifoaming agent (simethicone) (Bohuihua Huihua Chemical Co., Ltd.) 0.1 part.

Embodiment 2

[0030] (1) In the reaction kettle, add 92.3 parts of machine oil above SH grade, 0.1-0.2 parts of potassium isooctanoate, 0.2 parts of sodium ricinoleate, and 1.1-1.3 parts of calcium alkyl salicylate in order by parts by weight; 1.6 to 2.0 parts of alkyl thiophosphate; 3.7 parts of polybutylene succinimide, stirring while heating and keeping the temperature at about 55°C;

[0031] (2) After it is all mixed evenly, filter through a mucus filter;

[0032] (3) Test against the national standard, and if there is any deficiency, add viscosity modifier, pour point depressant, antifoaming agent and other additives to adjust to the national standard. Additives include viscosity improver (ethylene propylene copolymer (OCP) viscosity index improver Bohuihua Chemical Co., Ltd.) 0.2 parts, pour point depressant (polyα-olefin) 0.2 parts, antifoaming agent (simethicone) (Bohuihua Huihua Chemical Co., Ltd.) 0.2 parts.

Embodiment 3

[0034] A kind of preparation method of lubricating oil is characterized in that, comprises the following steps:

[0035] (1) In the reaction kettle, add 90 parts of machine oil above SH grade, 0.3 parts of potassium isooctanoate, 0.3 parts of sodium ricinoleate, 1.4 parts of alkyl calcium salicylate, alkyl thio 2 parts of phosphate, 3.7 parts of polybutylene succinimide, stirring while heating and keeping the temperature at about 55°C;

[0036] (2) After it is all mixed evenly, filter through a mucus filter;

[0037] (3) Test against the national standard, and if there is any deficiency, add viscosity modifier, pour point depressant, antifoaming agent and other additives to adjust to the national standard. Additives include viscosity improver (ethylene propylene copolymer (OCP) viscosity index improver Bohuihua Chemical Co., Ltd.) 0.5 parts, pour point depressant (polyα-olefin) 0.5 parts, antifoaming agent (simethicone) (Bohuihua Huihua Chemical Co., Ltd.) 0.5 parts.

Abstract

The invention discloses lubricating oil, which comprises the following components in part by weight: 90 to 93 parts of engine oil of over SH level, 0.1 to 0.3 part of potassium isooctanoate, 0.1 to 0.3 part of sodium sulforicinolate, 1.0 to 1.4 parts of alkyl calcium salicylate, 1.5 to 2 parts of alkyl thiophosphate and 3.7 parts of polybutene succinamide. A preparation method for the lubricating oil comprises the following steps: (1) adding the components into a reaction kettle according to the formulation in turn, heating and stirring the components at the same time, and preserving the temperature at about 55 DEG C; (2) after all the components are uniformly mixed, filtering the mixture with a viscous solution filter; and (3) adding 0.3 to 1.5 parts of additives into the mixture. The additives comprise 0.1 to 0.5 part of viscosity improver, 0.1 to 0.5 part of pour point reducer and 0.1 to 0.5 part of anti-foaming agent.

Description

technical field [0001] The invention relates to a lubricating oil and a preparation method thereof, in particular to a lubricating oil which can be used in various high-proportion methyl (ethyl) alcohol gasoline electric injection engines. Background technique [0002] "Automobile (M85)" stipulates that it is blended with 84%~86% (volume fraction) of methanol and 16%~14% (volume fraction) of motor gasoline (in line with GB 17930) and additives to improve performance Methanol gasoline (M85) for vehicles, according to the definition of the national standard "Methanol gasoline for vehicles (M85)", "The products covered by this standard are suitable for use as fuel for vehicles with methanol gasoline (M85) ignition engines." Applicable Gasoline vehicles can only have the following three types: [0003] - modified ignition engine vehicles; [0004] - Methanol vehicles; [0005] - Ignition engine vehicles that do not require modification. [0006] In recent years, with the pro...
