Abstract
The invention discloses an environmental protective safe degreasing abluent, which is allocated by 20-100% dicarboxylic acid ester and 0-80% oil hydrocarbon, wherein the dicarboxylic acid ester 1-3 component of C4-6 dicarboxylic acid C1-C5 dialkyl ester; the oil hydrocarbon is C10-C12 oil hydrocarbon solvent; the washed mechanics, apparatus and element are put into abluent under 50-80 deg.c to remove grease, which is cooled to 20-30 deg.c after cleaning to evolve grease from abluent to recycle abluent after removing grease.
Description
Technical field:
The present invention relates to main is the detergent composition of base-material with the on-surface-active compound, contains hydrocarbon, kind solvent; The diester that contains acyclic saturated polybasic acid ester, particularly C4～C6 simultaneously.
Background technology:
Current, the main raw material that clean-out system adopted that is used for solvent degreasing is halogenated hydrocarbon and petroleum hydrocarbon material, in concrete grease-removing agent, and this two classes raw material or use respectively or mix and use with certain proportion.The common toxicity of halohydrocarbon is strong and ODP value is bigger, and some is disabled, some has been prescribed and has limited the time limit that uses, and the petroleum hydrocarbon grease-removing agent exists that flash-point is low, inflammable, big or the like the drawback of danger.For the consideration of environmental protection aspect, external (as Japan) is a large amount of now to adopt the petroleum hydrocarbon material to clean as the solvent degreasing agent.But petroleum hydrocarbon needs the complete special cleaning machine tool equipment of safety features owing to easily fire during use.This kind equipment price is high, and general enterprise is difficult to bear.In addition, the saturated back of lipid that is dissolved in after existing the cleaning in the clean-out system just can't be used, and burns or discards the pollution that all can cause environment.
Summary of the invention:
At the defective that prior art exists, the present invention aims to provide a kind of safety, environmental friendliness, wide application, effective and economic degreased cleaning agent.
Technical scheme of the present invention is: adopt organic acid acetic or/and its mixture as main raw material, or mixes the composition degreased cleaning agent separately or with its petroleum hydrocarbon with certain flash-point with it.Its ingredient and percentage composition (W%) are:
Dicarboxylic esters 20～100
Petroleum hydrocarbon 0～80
Wherein: described dicarboxylic esters is 1～3 kind in di-carboxylic acid two C1～C5 alkyl ester of C4～C6, and described petroleum hydrocarbon is the petroleum hydrocarbon solvent of C10～C12.Collocation method is also very simple, in proportion raw material is mixed.Described dicarboxylic esters is advisable with the di-carboxylic acid dimethyl ester of C4～C6.Be commonly used with following prescription especially in the above-mentioned prescription, effect might as well.
Dicarboxylic esters 60～100
Petroleum hydrocarbon 0～40
The molten clean-out system of this degreasing is colourless～little Huang or little grey transparent liquid, its burning-point 70 ℃～more than 120 ℃, the ODP value is 0, toxicity is minimum, to environment do not have harm, degreasing power is stronger.Can be used for the mineral oil in the component, pipeline etc. of machinery, instrument, equipment, the cleaning of vegetables oil, also can be used for the cleaning of most of organic high molecular polymers.Purging method also without limits, the whole bag of tricks cleans can to adopt ultrasonic wave, spray, scrub etc.Also can adopt the combined method of these methods to clean.To mineral oil, vegetable and animals oils, and other functional greases can both under common cleaning condition, reach more than 99% by extrusion rate.
Degreased cleaning agent by the present invention's preparation has a particular performances, 50 ℃～80 ℃ carry out cleaning by degreasing after, after the grease-removing agent temperature is reduced to 20 ℃～35 ℃ scopes, the greasy dirt that is dissolved in the cleaning process in the grease-removing agent will be separated out from grease-removing agent, the emersion liquid level, can easily greasy dirt be separated from degreasing solvent, realize the repeated use of grease-removing agent, can significantly reduce the work-ing life of cleaning cost, prolonging grease-removing agent.
Compared with prior art, the present invention's characteristics of giving prominence to are: 1. raw material variety is few, the source is abundant; 2. product burning-point height, toxicity are low; 3. wide application, easy to use; 4. reusable, save use cost, the few environmental pollution of letter; Most important character is that greasy extrusion rate is up to more than 99%.
Below with specific examples the present invention is further specified.
Embodiment:
Example 1
When using ultrasonic wave to clean with Methyl glutarate to mechanical part, under 50～70 ℃ of the temperature, 5 minutes time, the whole wash-outs of the mineral dregs of fat wherein come out.Mineral oil is separated out after waiting to reduce to room temperature, and is clear through the visor display interface, separated, and Methyl glutarate is reused again.Cleaning by degreasing efficient reaches more than 99% after testing.
Example 2
Prepare degreased cleaning agent with following raw material and proportioning (W%):
Dimethyl adipate: 30%
Methyl glutarate: 40%
Carbon ten solvents: 30%
Material is stirred the product water white transparency in container.Use ultrasonic wave to clean 5min to component of machine at 50～55 ℃, component of machine innner and outer face cleaning, light show the metal true qualities.Greasy dirt is separated out after waiting to reduce to room temperature, places after the visor display interface is clear, is separated, and clean-out system is reusable.Cleaning efficiency reaches more than 99%.
Example 3
Prepare degreased cleaning agent with following raw material and proportioning (W%):
Diamyl succinate 25%
Pentanedioic acid dipropyl 5%
Polycizer W 260 40%
Compound method, cleaning process, separation and cleaning efficiency are with example 2.
Example 4
Press dimethyl succinate; 50%, Methyl glutarate: 50% part by weight preparation degreased cleaning agent.Compound method, cleaning process, separation and cleaning efficiency are with example 2
Example 5
Press Methyl glutarate: 20%, C8 petroleum hydrocarbon: 80% part by weight preparation degreased cleaning agent.Compound method is with example 2, the wash machine component condition: carry out pressure injection and cleaned (1～5 atmospheric pressure) 2～5 minutes under normal temperature condition.Cleaning performance 99%.
