Abstract
The invention provides an engine cleansing agent with convenient use and high efficiency and a preparation method thereof, wherein, the engine cleansing agent comprises preparation steps as follows according to the parts by weight: (1) giving heating and stirring for 200 parts of naphthenic acid from the room temperature for an hour until the temperature reaches 60 DEG C; (2) when the temperature of the naphthenic acid is heated up to 60 DEG C, adding base oil 650SN of 450 parts, pour point depressants of 4 parts, viscosity index improver of 6.5 to 8 parts, and high-alkaline synthetic calcium sulphonate as detergent of 3.5 to 5 parts into the naphthenic acid; (3) heating up and giving stirring for the mixed components until to 70 DEG C, and continuing stirring for an hour at the constant temperature of 70 DEG C; (4) carrying out filtering to obtain finished products. The engine cleansing agent adopts medicinal oil, which can be used in the engine with lubricating oil, without frequent replacement, therefore, the usage is very convenient and the use time of lubricating oil and service life of the engine are extended. The preparation method of the invention has the advantages of simple technique and high yielding.
Description
Technical field
The present invention relates to technical field of chemistry, relate in particular to a kind of engine cleansing agent and preparation method thereof.
Technical background
In the engine use, grow with time and to produce a lot of greasy filth at engine interior.The existence of these greasy filth can have a strong impact on the service efficiency of engine, even shortens its work-ing life and oil consumption, increase exhaust gas emission.Therefore, need often to use engine cleansing agent that engine interior is cleaned.
Engine cleansing agent at present commonly used is aqua, generally the time must emit in-engine lubricating oil earlier, inject the clean-out system cleaning then.And for fear of the infringement engine, general each scavenging period can only have 3-5 minute, just must drain clean-out system only afterwards.Therefore use very trouble.Therefore, be badly in need of easy to use, engine cleansing agent efficiently at present.
Summary of the invention
The purpose of this invention is to provide a kind of easy to use, engine cleansing agent and preparation method thereof efficiently.
For achieving the above object, the present invention has taked following technical scheme:
Engine cleansing agent of the present invention is grouped into by following one-tenth by weight: 200 parts of naphthenic acid; 450 parts of 650SN base oils; 4 parts of pour point depressant for crude oil; Viscosity index improver 6.5-8 part; High base number calcium alkylbenzenesulfonate purification agent 3.5-5 part.
Preparation method of the present invention is made up of following steps:
1) 200 parts of naphthenic acid begin to heat up from room temperature and stir, and keep to 60 ℃ and stir 1 hour;
2) when naphthenic acid is warmed up to 60 ℃, 450 parts of 650SN base oils, 4 parts of pour point depressant for crude oil, viscosity index improver 6.5-8 part, high base number calcium alkylbenzenesulfonate purification agent 3.5-5 part are added in the naphthenic acid;
3) after mixed composition heats up and is stirred to 70 ℃ 70 ℃ of constant temperature restir 1 hour;
4) filtration gets product.
Described 650SN base oil, pour point depressant for crude oil, viscosity index improver, high base number calcium alkylbenzenesulfonate purification agent all can adopt prior art products.
Engine cleansing agent of the present invention is a finish, can put into engine with lubricating oil and use, and the most of petroleum products that adopts of its cost does not damage any parts of engine.Compare with existing waterborne cleaning agent, product of the present invention has a clear superiority in.Do not need frequent replacing, use very conveniently yet, and can prolong lubricating oil duration of service and engine life.Check data shows that product of the present invention can prolong the machine oil actual service life more than 1000 kilometers in cleaning process.Preparation method's technology of the present invention is simple, the yield height.
Embodiment
Below in conjunction with specific embodiment content of the present invention is described further:
Present embodiment uses raw material all to adopt prior art products.
Calculate by weight, get 200 parts of naphthenic acid, begin to heat up from room temperature and stir, keep to 60 ℃ and stirred 1 hour.Then 450 parts of 650SN base oils, 4 parts of pour point depressant for crude oil, viscosity index improver 6.5-8 part, high base number calcium alkylbenzenesulfonate purification agent 3.5-5 part are added in the naphthenic acid.After mixed composition heats up and is stirred to 70 ℃ 70 ℃ of constant temperature restir 1 hour.The filtration engine cleansing agent that gets product.
Present embodiment product service test experimental data is as follows:
| Sequence number | Vehicle | Car plate | Car age | Capable milimeter number | Use front engine | Use product number of times of the present invention | Use rear engine |
| 1 | 7 passenger cares | Guangdong AN5008 | 9 years | 150,000 kilometers | Greasy filth, stain carbon are arranged | 3 times | Substantially clean |
| 2 | The liberation tank car | Guangdong Y04944 | 4.5 year | 300,000 kilometers | A lot of stain carbon, greasy filth | 3 times | Substantially clean |
| 3 | Red flag car | Guangdong AGY861 | 2 years | 50,000 kilometers | With in the engine greasy filth being arranged soon | 3 times | Substantially clean |
