Cleaning solution for engine

Abstract

The invention relates to a cleaning solution and particularly relates to a cleaning solution for an engine. The cleaning solution is prepared from the following substances in parts by weight: 15-25 parts of coconut high-carbon fatty alcohol polyoxyethylene ether, 18-25 parts of polyoxyethylene nonylphenol ether, 3-5 parts of polyisobutene amine, 2-5 parts of methacrylic acid, 15-25 parts of fatty alcohol polyoxyethylene ether sulfate, 3-5 parts of potassium polyoxyethylene laurylether phosphate MAEPK, 1-5 parts of ethylene oxide-propylene oxide copolymers, 25-45 parts of sulfonated castor oil, 0.05-0.08 part of an ethylene glycol-ethyl ether mixed solution, 4-6 parts of sodium silicate, 15-25 parts of ethyl acetate and 45-55 parts of water. The cleaning solution for the engine, disclosed by the invention, can generate a great number of randomly moving colloidal suspended particles together with oil stains, dust, oil dirt and rust in the engine after being added into the engine so as to emulsify and decompose dirt and the like; and due to the addition of a great deal of dispersing agent, the dispersed particles cannot be caked and can be dispersed into an organic solvent so as to be directly discharged out of the engine.

Description

technical field [0001] The invention relates to a cleaning fluid, in particular to an engine cleaning fluid. Background technique [0002] For engine cleaning, in the 1960s and 1970s, diesel oil was used as a cleaning agent. When cleaning, the old engine oil needs to be drained first, and then the same amount of diesel oil should be injected, and the car should be idled for 10 minutes. Then inject new oil, and it's over. The injected diesel can carry out the oil dirt, metal debris and inclusions in the engine. The engine after washing is about 50% cleaner than before, but there are still metal particles deposited in the dark corners, which are difficult to discharge. Moreover, diesel oil is discarded after being used as a cleaning agent, or it needs to be treated as waste oil, which is inconsistent with the advanced concepts of environmental protection, emission reduction, and energy saving; the sulfuric acid content of diesel oil is higher than that of engine oil, and it ...

After washing, the engine is about 50% cleaner than before washing, but there are still metal particles deposited in dark corners, which are difficult to discharge

Moreover, diesel oil is discarded after being used as a cleaning agent, or it needs to be treated as waste oil, which is inconsistent with the advanced concepts of environmental protection, emission reduction, and energy saving; the sulfuric acid content of diesel oil is higher than that of engine oil, and it has the effect of time accumulation, which will cause oil seal damage The oil leakage will accelerate the damage to the bearing; the production, transportation, storage and use of diesel oil are not environmentally friendly and will cause fire hazards

[0003] There are a lot of engine cleaning fluids on the market now, and the mixed cleaning method is used. When these flammable and explosive liquids are used as cleaning additives, the engine is in a high temperature state, which increases the risk of fire; refined petroleum and solvents come into contact with the high temperature engine, resulting in Toxic gases and unpleasant odors that are extremely harmful to human health; the cleaning process increases the discharge of 450ml of flammable liquid; these existing cleaning agents in the market are acidic, and the accumulation of time will also damage the oil seal and cause oil leakage, and Accelerate damage to bearings and pollute the environment; flammable and explosive refined petroleum, solvent production, transportation, storage, and use are also not environmentally friendly and sometimes cause fire hazards
