Abstract
The invention provides a weakly alkaline environment-friendly aluminum product surface degreasing agent and a preparation method thereof. The weakly alkaline environment-friendly aluminum product surface degreasing agent comprises the following components in percentage by mass: 5-6% of polyoxyethylene octyl phenol ether, 6-8% of sodium dodecyl benzene sulfonate, 3-4% of polyoxyethylene fatty alcohol ether sodium sulfate salt, 1-2% of sodium silicate, 4-5% of sodium carbonate, 5-8% of normal propyl alcohol, and 67-76% of de-ionized water. As the pH value is approximately neutral, no great corrosion effect is generated on an aluminum product; and the degreasing agent has high biodegradability, causes no environmental pollution, is environmentally friendly and safe, and is highly efficient in removing oil stains and grease.
Description
Technical field
The present invention relates to easy-open lid production technical field, relate in particular to a kind of weakly alkaline environmental protection aluminium material surface grease-removing agent with and preparation method thereof.
Background technology
Easy-open lid production process need to be used and meet other aluminium of food grade, but in the preparation and transportation of aluminium, easily be subject to lubricating oil, machine oil, releasing agent, the oily matters such as sweat stain pollute, carry out the processing such as passivation, coating at aluminium before, must adopt grease-removing agent by these oiliness contaminant removal, otherwise can cause follow-up varnish coating to occur the macroscopic irregularitys such as shrinkage cavity, flake.
Traditional grease-removing agent contains phosphoric acid salt, and its waste water easily causes the rich oxidation stain of water body; In addition, traditional grease-removing agent also, generally containing alkaline sodium hydroxide, easily causes aluminium burn into surface blackening, affects product appearance, and workman has larger danger while operating.Also some subalkaline skimmed prods have been there are in recent years, for example Chinese patent discloses the agent of a kind of aluminium material surface degreasing degreasing, application number is CN201210323986.7, disclosure of the invention the agent of aluminium material surface degreasing degreasing, component by following weight percent forms: sodium carbonate 5-6%, water glass 4-5.5%, polyoxyethylenated alcohol sodium sulfate 1.5-2.5%, hydrolytic polymaleic anhydride 15-19%, hydroxy ethylene diphosphonic acid 8-12.5%, alkylphenol polyoxyethylene 0.8-1.3%, all the other are softening water.Although this invention declares that its product is nontoxic, tasteless, it is not quick-fried not fire, it is closely neutral to clean waste liquid, containing strong acid, heavy metal ion, environmentally safe, but in 4.1 material requirements in China standard GB/T/T 13171.2-2009 washing powder (without phosphorus type) because environmental security is clearly classified the alkylphenol polyoxyethylene this invention Suo Shu as forbidding material.
Given this, a kind of grease-removing agent product of, Environmental Safety corrosion-free to aluminium is needed in market badly.
Summary of the invention
For the deficiencies in the prior art, the invention reside in a kind of aluminium material surface grease-removing agent that does not contain strong acid and strong base and can not cause the rich oxidation stain of water body is provided.
For achieving the above object, the present invention is achieved by following technical proposals:
A weakly alkaline environmental protection aluminium material surface grease-removing agent, its constituent mass per-cent is, polyoxyethylene octylphenol ether 5-6%, Sodium dodecylbenzene sulfonate 6-8%, polyoxyethylene aliphatic alcohol ether sulfuric ester sodium salt 3-4%, water glass 1-2%, sodium carbonate 4-5%, n-propyl alcohol 5-8%, deionized water 67-76%.
A making method for weakly alkaline environmental protection aluminium material surface grease-removing agent, the steps include:
1) according to described mass percent 6-8%, weigh Sodium dodecylbenzene sulfonate, according to described mass percent 67-76%, measure deionized water, Sodium dodecylbenzene sulfonate is dissolved in to deionized water;
2) according to described mass percent 4-5%, weigh sodium carbonate, be dissolved in the liquid of step 1) acquisition;
3) according to described mass percent 3-4%, weigh polyoxyethylene aliphatic alcohol ether sulfuric ester sodium salt, be dissolved in step 2) in the liquid that obtains;
4) according to described mass percent 1-2%, weigh water glass, be dissolved in the liquid of step 3) acquisition;
5) according to described mass percent 5-6%, weigh polyoxyethylene octylphenol ether and weigh n-propyl alcohol according to described mass percent 5-8%, polyoxyethylene octylphenol ether is put into n-propyl alcohol, then liquid step 4) being obtained adds in the mixture of polyoxyethylene octylphenol ether and n-propyl alcohol, stir, can obtain finished product.
Described Sodium dodecylbenzene sulfonate adopts linear alkylbenzene sulphonic acid (LAS), linear chain structure readily biodegradable, and biological degradability can be greater than 90%, and environmental pollution degree is little, meets the environmentally safe requirement of national standard completely.
A kind of its principle of weakly alkaline environmental protection aluminium material surface grease-removing agent of the present invention is: described Sodium dodecylbenzene sulfonate and polyoxyethylene aliphatic alcohol ether sulfuric ester sodium salt are outstanding aniorfic surfactant, more responsive to the water hardness, therefore add water glass and sodium carbonate as the tenderizer that reduces the water hardness; Described Sodium dodecylbenzene sulfonate and polyoxyethylene aliphatic alcohol ether sulfuric ester sodium salt are outstanding aniorfic surfactant, add appropriate nonionic surface active agent can increase decontamination scope, therefore add polyoxyethylene octylphenol ether, finally by described components dissolved in deionized water, avoid ion pair water hardness to exert an influence, and then affect degreasing power.
Beneficial effect of the present invention is: pH value approaches neutral, can not produce larger corrosive nature to aluminium, and biological degradability is high, environmentally safe, Environmental Safety, high-efficient greasy dirt removing grease.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.
