Description
Technical Field
The invention relates to the field of preparation of cleaning agents, in particular to an engine cleaning agent and a preparation method thereof.
Background
The cleaning agent for the interior of the engine is a product developed for solving the problem of oil sludge, colloid, carbon deposition, paint film, dirt and other deposits formed in the lubricating system, consists of a plurality of components with very strong cleaning capability, and is an additive capable of automatically cleaning the internal system of the lubricating system. The cleaning agent for the interior of the engine is added into the crankcase of the engine, and flows along with engine oil during the operation of the engine, so that the cleaning process can be completed, the colloid can be dissolved, and the adhered sediments become loose and then fall off. Paint film, carbon deposit, oil sludge and other deposits on piston rings, piston skirt portions and the like can be thoroughly removed. The cleaned deposits can be filtered by an oil filter along with the circulation of the oil or deposited in an oil pan and removed together when the oil filter and the oil pan are replaced and cleaned.
The existing engine cleaning method is to pour the cleaning agent into the engine oil tank and then to run for about 20 minutes to clean, and because the cleaning time is too short and the cleaning steps are too simple, the cleaning effect is not ideal. The existing cleaning agent basically takes a solvent as a main body and is assisted with other chemicals, and has the advantages of quick and labor-saving engine cleaning, and the defects that the solvent used by some formulas is toxic, and some patents have no actual use methods, so that maintenance personnel of the engine cannot perform cleaning work; the solvents used in most patents are the cellosolve family of products, such as: the use of ethylene glycol butyl ether, ethylene glycol monobutyl ether, propylene glycol methyl ether, ethylene glycol monobutyl ether, and polyethylene oxide-propylene oxide monobutyl ether, as a large amount of these cellosolve solvents, is liable to be flammable and dangerous.
