What deoiling adopted at present is the method that organic solvent, hot alkaline solution and surfactant soln clean.Organic solvent method is divided into two classes: a class is to be actives with the halohydrocarbon, and the 86-98798 as day disclosure special permission discloses the washing composition that contains ethylene dichloride 75%.Detersive power is 86%, and ability still can.But ethylene dichloride toxicity is bigger, damages the ozone layer not environmental protection again.Another kind of is to be actives with the stone hydrocarbon, as English Patent " 1066407 " liquid concentration metal cleaner and grease-removing agent, is main actives with kerosene.This method not only wastes energy, and also contaminate environment has potential safety hazard again.Hot alkaline solution washing deoiling efficient is low also not to be included, and to corrosion of metal and bigger to the stimulation of skin.As United States Patent (USP) 4048121, can remove grease and dirt on the metal≤50 ℃ the time with the straight-chain alkyl polyoxyethylene ether of 40% alkane alkali, 7% soda ash and 5%.But also will heat during operation, and corrosion is stronger, the deoiling effect is also not ideal enough.
For addressing this problem, China begins to promote " water base metal cleaning agent " from " six or five ", but uses still not general.According to the statistics made by the departments concerned, China is used in metal cleaning aspect leaning solvent such as kerosene, diesel oil every year still more than 500,000 tons.
Summary of the invention
The purpose of this invention is to provide a kind of efficient, environmental protection, multifunctional deoiling decontaminant, to solve the above-mentioned problems in the prior art.With this deoiling decontaminant of the present invention, except that having the efficient degreasing soil removability, and can use (the tap water dissolving is used down for 20-30 ℃) at low temperatures, corrodibility and pungency also reduce greatly simultaneously.Product of the present invention can be used for multiregion fields such as metal, fabric, pottery, plastics, woodenware and cleans, and especially the deoiling effect of component of machine is better.
A kind of high effective environmental protection multifunctional deoiling decontaminant of the present invention, by weight percentage, form by following component:
Sodium dodecylbenzene sulfonate 0.2-10%, soda ash 0-30%, triethanolamine oleate 0.2-6%, caustic soda 0-10%, polyoxyethylene nonylphenol ether 0.2-2%, water glass 3-10%, fatty alcohol-polyoxyethylene ether 0.2-2%, Sodium sulfate anhydrous.min(99) 0-10%, cocoanut fatty acid diethanolamide 0.2-2%, tertiary sodium phosphate 0-30%, alkyl polyglycoside 0.2-2%, tripoly phosphate sodium STPP 0-15%, glucose amide 0.2-2%, ethylenediamine tetraacetic acid (EDTA) 0-2%, carboxymethyl cellulose 0-2%.
In above-mentioned deoiling decontaminant, two big class materials are arranged: a class is the kinds of surface promoting agent, and another kind of is multiple washing assistant.Sodium dodecylbenzene sulfonate, triethanolamine oleate are anion surfactants.Polyoxyethylene nonylphenol ether, fatty alcohol-polyoxyethylene ether, alkyl polyglycoside, glucose amide are nonionogenic tensides.These tensio-active agents are main active components of a kind of high effective environmental protection multifunctional deoiling decontaminant among the present invention, have significant emulsification, dispersion force, good dissolving and wettability, and be that multiple different components, different component are composite, thereby produced good synergistic function, thereby improved comprehensive deoiling ability of the present invention greatly.
Soda ash and/or caustic soda, water glass, Sodium sulfate anhydrous.min(99), ethylenediamine tetraacetic acid (EDTA) and/or tertiary sodium phosphate, tripoly phosphate sodium STPP and/or carboxymethyl cellulose all are washing assistants.
The preferred triethanolamine oleate of the present invention is because it has special emulsifying capacity to grease.Particularly composite with Sodium dodecylbenzene sulfonate, cooperative synergism effect is more obvious.
The present invention is also preferred to remove the stronger coco-nut oil fatty acid trolamine of mineral oil ability, thereby has improved the ability of removing mineral oil.
The present invention is also preferred alkyl polyglycoside, glucose amide is based on renewable plant material the 4th and represents surface-active agent, is to consider from the ecological security aspect on the one hand, simultaneously also because they have a series of excellent properties, and good compatibility arranged.When composite, can produce synergistic function as alkyl polyglycoside and anion surfactant.Experimental results show that: 50 ℃, when activity concentration 0.1%, the water hardness 16, alkyl polyglycoside in varing proportions with Sodium dodecylbenzene sulfonate composite after, to the detersive power of the plate that scribbles butter, with the detersive power that how much characterizes compound of dishwashing number, the many more detersive poweies of dishwashing number are good more.The dishwashing number of single alkyl polyglycoside is 8, the dishwashing number of single Sodium dodecylbenzene sulfonate is 4, the dishwashing number that adds the compositional liquor of 20% (the Sodium dodecylbenzene sulfonate amount) alkyl polyglycoside and Sodium dodecylbenzene sulfonate is 15, almost is the twice of single Sodium dodecylbenzene sulfonate dishwashing number.As seen composite back synergistic function is obvious.
Principal character of the present invention just is a small amount of (0.2%) kinds of surface promoting agent science composite, produces synergistic function, has improved deoiling effectiveness.
Principal character of the present invention also is the combining of alkali lye oil removing, soap lye oil removing, solvent oil removing and tensio-active agent oil removing science not only improved oil removing effectiveness, has also reduced the oil removing operational condition.For example general alkali lye oil removing will be at 70-80 ℃, and deoiling decontaminant of the present invention can be at normal temperature (20-30 ℃) operation deoiling.
