Embodiment 1

[0008] Composed of the following components by mass percentage: 10% dichloromethane, 20% trichloroethylene, 5% naphtha, 2.5% o-dichlorobenzene, 0.1% dimethyl silicone oil, 0.5% alkyl succinimide And the balance of odorless kerosene.

[0009] The preparation method is carried out according to the following steps: first put the calculated and weighed odorless kerosene into the solvent reactor, and then successively put the calculated and weighed dichloromethane, trichlorethylene, naphtha, o-dichlorobenzene, dimethyl Silicone oil and alkyl succinimide are slowly added into the solvent reactor, and the stirrer rotates at 30 rpm under normal temperature conditions, stirring until the solvent is transparent.

Embodiment 2

[0011] Composed of the following components by mass percentage: 25% dichloromethane, 5% trichloroethylene, 15% naphtha, 0.1% o-dichlorobenzene, 2.0% dimethyl silicone oil, 0.1% alkyl succinimide And the balance of odorless kerosene.

[0012] The preparation method is the same as in Example 1.

[0013] Example 2:

[0014] Composed of the following components by mass percentage: 15% dichloromethane, 13% trichloroethylene, 10% naphtha, 2% o-dichlorobenzene, 1.0% dimethyl silicone oil, 0.3% alkyl succinimide And the balance of odorless kerosene.

[0015] The preparation method is the same as in Example 1.

[0016] The appearance of the products of Examples 1, 2, and 3 is uniform and transparent liquid; relative density: 0.70~0.90; open flash point: ≥66°C; ignition point: ≥75°C.

[0017] At room temperature, using Examples 1, 2, and 3 of the present invention to clean petroleum equipment by spraying, wiping, brushing, and immersion cleaning, all have strong decontamination capa...

Abstract

The invention discloses a petroleum equipment cleaning agent which has good safety, saves energy and is suitable for multiple cleaning modes, and a preparation method. The petroleum equipment cleaning agent comprises the following components in percentage by mass: 10-25% of dichloromethane, 5-20% of trichloroethylene, 5-15% of naphtha, 0.1-2.5% of o-dichlorobenzene, 0.1-2.0% of dimethicone, 0.1-0.5% of alkylbutanimide and the balance of tasteless kerosene. The preparation method comprises the steps of firstly putting the calculated and weighed tasteless kerosene into a solvent reactor; then slowly adding the calculated and weighed dichloromethane, trichloroethylene, naphtha, o-dichlorobenzene, dimethicone and alkylbutanimide into the solvent reactor sequentially; stirring at a speed of 30rpm at normal temperature by a stirrer until the solvent is transparent.

Description

technical field [0001] The invention relates to an equipment cleaning agent, in particular to a petroleum equipment cleaning agent which is safe, energy-saving and suitable for various cleaning methods and a preparation method thereof. Background technique [0002] Petrochemical plants, ethylene plants, oil production plants, oil transportation companies and other enterprises all need to regularly clean the slightly viscous oil stains on various equipment. Currently, the cleaning agents used are extremely flammable93 # 、97 # or 120 # Gasoline, on-site operation is prone to fire, which seriously endangers personal and property safety. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and provide a petroleum equipment cleaning agent with good safety, energy saving, and suitable for various cleaning methods and a preparation method. [0004] The technical solution of the pr...
