Description
Technical field
The present invention relates to a kind of oxidizing layer of stainless steel cleaning agent and its preparation method and application, metal surface cleans and field of surface treatment.
Background technology
In producing stainless steel process, inevitably can generate oxide layer, the existence of oxide layer not only has influence on stainless attractive in appearance,Also can have influence on stainless steel and further process processing, the removal of oxidizing layer of stainless steel has become in stainless steel processing indispensableStep. The oxidizing layer of stainless steel cleaning agent using at present, substantially taking inorganic acid as main, comprises nitric acid, hydrochloric acid, phosphoric acid, hydrofluoric acidDeng (CN200510020976.6, CN200710133741.7, material protection, 2010,43,28, clean the world, 2013,29,29). Inorganic acid has stronger corrosivity, can reach the object of cleaning oxidizing layer of stainless steel, but taking inorganic acid as mainOxidizing layer of stainless steel cleaning agent shorter service life, waste water generation is large, and inorganic acid environment degradable is poor, environmental pollutionSeriously. Under the pressure of environmental emission reduction, the oxidizing layer of stainless steel cleaning agent that contains higher proportion inorganic acid is performance gradually in useGo out certain limitation. Although organic acid has good biological degradability, due to acidity a little less than, carry with organic acid separatelyClean oxidizing layer of stainless steel for sour environment, effect is substantially poor, and cost is relatively high.
Cyclodextrin (cyclodextrin is called for short CD) is formed by connecting by α-Isosorbide-5-Nitrae-glycosidic bond by D-(+)-glucopyranose unitsCyclic oligosaccharide, is truncated cones shape, has special construction and the character of " inner chamber is hydrophobic, and outer wall is hydrophilic ". Due to cyclodextrinPolyhydroxy and hydrophobic cavity structure, make it there is very strong complexing and inclusion effect, Jin Er to metal ion in waterIn weak acid environment, can effectively " peel off " oxidizing layer of stainless steel, realize with biodegradable organic acid and replaced inorganic acidPrepare oxidizing layer of stainless steel cleaning agent. In addition, after cyclodextrin molecular complexing and inclusion metal ion, be easy to from cleaning system withThe form of Inclusion Complexes is separated out. Therefore, in the time that the cleaning performance of oxidizing layer of stainless steel cleaning agent can not reach requirement, as long as addAdd a certain amount of cyclodextrin and organic acid and can continue to meet cleaning requirement, waste water generation is few, relatively environmental protection.
Summary of the invention
The object of the present invention is to provide a kind of oxidizing layer of stainless steel cleaning agent and its preparation method and application.
A kind of oxidizing layer of stainless steel cleaning agent provided by the invention, described oxidizing layer of stainless steel cleaning agent is composed of the following components: matterThe cyclodextrin that amount percentage composition is 30%～50%, the organic acid that quality percentage composition is 10%～20%, quality percentage composition is10%～20% complexed surfactant, surplus is water;
Described cyclodextrin is in alpha-cyclodextrin, beta-schardinger dextrin-, gamma-cyclodextrin, hydroxypropylβ-cyclodextrin, methylated β-cyclodextrinOne or more mixture;
Described organic acid is one or more in formic acid, acetic acid, propionic acid, citric acid, oxalic acid, maleic acid, laurateMixture, optimization citric acid;
Described complexed surfactant be enuatrol, APG, lauryl sodium sulfate, cocoanut fatty acid diethanolamide,Two or more mixture in AEO, polyethylene glycol, preferably enuatrol, APG and coconut oil fatThe mixture of acid diglycollic amide; More preferably enuatrol, APG and cocoanut fatty acid diethanolamide mass ratio 1:1:1 mixture.
Preferably, described oxidizing layer of stainless steel cleaning agent is composed of the following components: the cyclodextrin that quality percentage composition is 35%～40%,Quality percentage composition is 15%～20% organic acid, the complexed surfactant that quality percentage composition is 15%～20%, and surplus isWater. More preferably described oxidizing layer of stainless steel cleaning agent is composed of the following components: the cyclodextrin that quality percentage composition is 35%, qualityPercentage composition is 15% organic acid, the complexed surfactant that quality percentage composition is 15%, and surplus is water.
The present invention also provides the preparation method of described oxidizing layer of stainless steel cleaning agent, and described method is: by cyclodextrin and composite surfaceActivating agent is dissolved in deionized water by component ratio, 50～70 DEG C of (preferably 60 DEG C) preferred 24.0h of stirring reaction 24.0h～96.0h(),Cool to room temperature, filters, and adds organic acid, 50～70 DEG C of (preferably 60 DEG C) stirring reactions in gained clear liquid by component ratioThe preferred 24.0h of 24.0h～96.0h(), be cooled to room temperature, to filter, filtrate is uniform solution, is described oxidizing layer of stainless steel clearLotion.
The present invention also provides described oxidizing layer of stainless steel cleaning agent at the application of cleaning in oxidizing layer of stainless steel, described application processFor: by oxidizing layer of stainless steel cleaning agent and water in mass ratio 5～10:100 be made into cleaning fluid, stainless steel device to be cleaned is soakedIn described cleaning fluid, at-10 DEG C～100 DEG C temperature, (preferably room temperature～80 DEG C, more preferably under room temperature condition) soaks 5～60 pointsClock, clear water rinses, and dries, and can remove the oxide layer of stainless steel device.
Beneficial effect of the present invention is mainly reflected in: the invention provides a kind of oxidizing layer of stainless steel cleaning agent based on cyclodextrin, systemPreparation Method is simple, use easy to operate, long service life, waste water generation is few, each component easily biological-degradable, environmental protection,And with low cost.
The present invention provides sour environment with the organic acid of degraded by environment, promotes " peeling off " of oxidizing layer of stainless steel with cyclodextrin, systemStandby oxidizing layer of stainless steel cleaning agent, not only can reach and use the identical cleaning performance of inorganic acid, and environmental protection, before applicationScape is wide. This oxidizing layer of stainless steel cleaning agent has the alternative potentiality taking inorganic acid as main oxidizing layer of stainless steel cleaning agent at present.
