Description

A kind of degreaser and preparation method thereof

Technical field

The invention belongs to daily use chemicals configuration product technical field, and in particular to a kind of degreaser and preparation method thereof.

Background technology

Degreaser is mainly grease cleaning agent, with extremely strong remove functional oil, emulsification, strong detergency, at present, most of families The lampblack absorber or gas range that front yard uses is added up due to prolonged, and on surface dense heavy oil stain can be formed, and cleaning becomes Obtain very difficult, common liquid detergent cannot be dissolved easily, but industrial conventional degreaser toxicity is larger, it is impossible to it is light Easy applying causes metal erosion or gets rusty easily in the family such as kitchen place, or strong acid and strong base solution, therefore, prepare one Mitigation is compared in the effect of kind, and the degreaser for going lipid strong is particularly significant.

The Chinese patent application of Publication No. 105002002A discloses a kind of environment-friendly type heavy oil dirt cleaning powder and its preparation Method, environment-friendly type heavy oil dirt cleaning powder is by following percentage by weight into being grouped into：Bentonite mine tailing 90-95% and dodecane Base benzene sulfonic acid sodium salt 5-10%.The invention to bentonite modified, by its good adsorptivity, hydrophily, viscosity, is touched by roasting Denaturation and lubricity, suspension stability and stronger ion exchange and fabulous purifying property so as in the neck of washing degreasing Domain is cleverly with the performance for substituting compound surfactant.But need to use external force friction, meeting during the invention use Mechanicalness is caused to damage.

The Chinese patent application of Publication No. 104818160A discloses a kind of kitchen duplicate removal finish and preparation method thereof, its It is made up of the raw material of following percentage by weight meter：Isomeric alcohol polyethenoxy ether 0.3~6.0%, AEO 0.5~ 8.0%th, organic base 0.1~5.0%, hydroxy ethylidene-diphosphate 0.1~6.0%, sodium carbonate 0.1~3.0%, sodium metasilicate 0.1~3.0%, sodium citrate 0.1~4.5%, essence 0.1~2.5%, balance of deionized water.Heavy oil is removed in the invention kitchen Agent does not contain solvent, and the highly basic without OH-, moderate performance is little to human body skin excitant, and corrosivity is minimum, to lampblack absorber, cooking stove Etc. there is very strong decontamination to deoil ability, but the duplicate removal finish that the invention is provided contains substantial amounts of strong basicity composition, meeting after use The protective layer of the equipment such as lampblack absorber is removed, embroideryization is susceptible to.

The content of the invention

In order to solve the deficiencies in the prior art, the invention provides a kind of degreaser and preparation method thereof, this goes Finish is weakly alkaline solution, and various inorganic constituents are with the addition of in composition, and metal surface can be made to produce passivation after use, is prevented Metal erosion.

Concrete technical scheme of the present invention is as follows：

A kind of degreaser, mainly by following mass fraction into being grouped into：Lauric acid amide of ethanol 8-12%, single bay Base phosphate 10-15%, laurel alcohol ether phosphate potassium 10-15%, ethylene glycol 8-10%, sodium acid carbonate 0.1-0.2%, nitrous acid Sodium 0.1-0.2%, calcium oxide 0.05-0.1%, calcium carbonate 0.05-0.1%, NaOH 1-2%, sodium citrate 1-2%, phosphorus Sour sodium 0.5-1%, magnesium chloride 0.05-0.1%, diethanol amine 4-6%, pH buffer 0.1-3%, essence 0.5-2% and water 30- 50%.

Further described degreaser, by following mass fraction into being grouped into：Lauric acid amide of ethanol 10%, list Tryfac 5573 13%, laurel alcohol ether phosphate potassium 12%, ethylene glycol 9%, sodium acid carbonate 0.16%, natrium nitrosum 0.14%th, calcium oxide 0.08%, calcium carbonate 0.07%, NaOH 1.6%, sodium citrate 1.4%, sodium phosphate 0.8%, chlorination Magnesium 0.07%, diethanol amine 5%, pH buffer 0.3%, essence 1% and water 45.38%.

Preferably, described essence is lemon oil.

Preferably, described pH buffer is citric acid.

Lauric acid amide of ethanol：With significantly emulsifying, deoil ability, it is often more important that act on and have on hardware There are the performances such as antirust, anticorrosion, and with good compatibility.

Single Tryfac 5573：With excellent emulsibility, animal and plant fat, fatty acid ester, silicone oil, mineral oil are had Excellent emulsifying capacity；Good wetting scourability and synergistic function can be just showed at low concentrations；And nontoxic, Non-stimulated, good with skin compatibility, high-effective low foam is easily rinsed, and corrosion-resistant, with alkali compounds in and using performing better than Ground cleaning effect.

Laurel alcohol ether phosphate potassium：The effect of other surfaces activating agent is mainly aided in, with the surface such as lauryl sulfate Active ingredient, can promote the cleaning capacity of other surfaces activating agent, and property is gentle, high with skin compatibility.

Diethanol amine：Some sour gas can be absorbed, organic salt is converted into, is prevented to corrosion of metal, and have one Fixed lubricant effect.

Present invention also offers a kind of preparation method of described degreaser, step is：

S1：By water, lauric acid amide of ethanol, single Tryfac 5573, laurel alcohol ether phosphate potassium, ethylene glycol, hydrogen-oxygen Change sodium, sodium citrate and diethanol amine to add in emulsification pot, be heated to 55-60 DEG C, stir, obtain latex A；
