Problems solved by technology

[0003] At present, most of the metal cleaners on the market contain harmful chemical components such as strong acid, strong alkali, phosphate and aluminum salt. These chemical components will not only cause certain damage to the metal surface, but also cause certain harm to the environment. At the same time Due to the complex process, the cost is high

Embodiment 1

[0039] The preparation of embodiment 1 chloride 1-hydroxyethyl-3-hexadecyl imidazole

[0040] Mix imidazole and 3.8 mL of hexadecane bromide (ratio of substance is 2:1) in 35 mL of ethyl acetate, stir for 10 minutes with magnetic force and mix well. Pour the mixture into a polytetrafluoroethylene liner with a capacity of 60mL, seal the polytetrafluoroethylene liner into a stainless steel reactor, and put it into a digital oven, heat it from room temperature to 120°C for 16 hours, and then cool it naturally to room temperature. Then the mixture was filtered to take out the filtrate, washed several times with distilled water to remove the imidazole that did not participate in the reaction, and the solvent ethyl acetate was evaporated with a rotary evaporator, and the resulting product 1-hexadecyl imidazole was dried in a vacuum oven at 70°C for 12 hours to constant weight. Obtain light yellow liquid, weigh product, 2.9g of 1-hexadecyl imidazole and 1ml of 2-chloroethanol (mass...

Embodiment 2

[0041] Embodiment 2 O, the preparation of O'-diphenyl dithiophosphoric acid-N, N-diethylammonium

[0042] Add 22.2g of phosphorus pentasulfide (0.1mol) and 37.6g of phenol (0.4mol) into a 250mL three-necked flask, and add 70mL of toluene as a solvent; while stirring, gradually raise the temperature to about 100°C and react for 45min; then raise the temperature until reflux, reflux 3h, the solid gradually disappeared during the reaction; the solution was slightly cold, boiled with a small amount of activated carbon to decolorize, filtered while it was hot, and the filtrate was cooled to room temperature; the obtained filtrate was transferred to a beaker, cooled in a water bath, and 22 mL of diethylamine was added drop by drop under stirring (0.2mol), the reaction system emits a large amount of heat, and the color of the liquid gradually becomes orange-red. When stirred rapidly with a glass rod, precipitation occurs, and it is left standing overnight at room temperature; filtered...

Embodiment 3

[0043] Example 3: Metal Stain Remover 1

[0044] Antifoaming agent tributyl phosphate 2g, cationic surfactant distearyl dimethyl ammonium chloride 8g, anionic surfactant sodium tosyl sulfonate 6g, as nonionic surfactant trade name Silicon surfactant 12g, sodium phosphate 20g and sodium silicate 10g, 1-hydroxyethyl-3-hexadecylimidazole chloride 2g prepared in Example 1, O, O'-diphenyl Dissolve 2 g of dithiophosphoric acid-N, N-diethylammonium in deionized water, and stir for about 30 minutes to obtain.

Abstract

The present invention provides an environmental protection type metal detergency agent with an anti-corrosion function. The environmental protection type metal detergency agent comprises: 0.3-5% of an antifoaming agent, 1-15% of a cation surfactant, 1-10% of an anion surfactant, 3-15% of a nonionic surfactant, 20-40% of a main cleaning agent, 2-5% of a corrosion inhibitor and the balance of deionized water, wherein the corrosion inhibitor comprises chloride 1-hydroxyethyl-3-hexadecyl imidazole and O',O'-diphenyl dithiophosphonic acid-N,N-diethylamine. The environmental protection type metal detergency agent is an efficient metal cleaning agent with characteristics of low alkali, low foaming, environmental protection, strong oil removing effect at a low temperature, and low corrosion.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an environment-friendly metal decontamination agent with anti-corrosion function. Background technique [0002] In the maintenance and repair of machining, mechanical equipment, automobiles, etc., diesel oil, kerosene or gasoline are mostly used as cleaning fluids to clean parts. This not only wastes energy, but also has potential unsafe factors. If you are not careful, it may lead to a fire. In recent years, a new type of metal cleaning agent has gradually been widely used. It can replace diesel, kerosene and gasoline to clean parts, and it is cheap and safe to use. It is very suitable for mechanized cleaning operations. It can wash metal without rust spots. [0003] At present, most of the metal cleaners on the market contain harmful chemical components such as strong acid, strong alkali, phosphate and aluminum salt. These chemical components will not only cause certa...
