Description
Technical field
The present invention relates to hole sealing agent technical fields, and in particular to a kind of high heat resistance corruption coating sealing reagent.
Background technique
Aluminium element is that most wide one of element is distributed in nature.Fine aluminium quality is soft, density is small, ductility is good, plasticity is high,
It can carry out various machinings and have good electric conductivity and thermal conductivity, electric conductivity is only second to, and purposes is very extensive.Due to
The intensity of fine aluminium is low, could only be made as structural material by by its alloying, obtaining the aluminium alloy that density is small, intensity is high
With.Aluminum alloy materials have a series of excellent physics, chemistry, mechanics and processing performance, can satisfy from kitchen meal apparatus to point
End science and technology is drilled industry to a variety of requirements of all trades and professions such as transportation and aerospace from building dress, is passed through in its people
It is used widely in the every field of Ji.
Aluminium is the active substance of chemical property, and surface will form one layer of oxide thin layer film in air, this layer of oxidation film exists
There is good corrosion resistance in dry atmosphere, but in the atmosphere of pollution and water, seawater, soil and various corrosive mediums, does not then have
Enough protective values.Therefore, aluminium and aluminum alloy surface require to be surface-treated in many cases, and anodic oxidation is that aluminium closes
The most common surface treatment means of gold.This method is that aluminium alloy is immersed in the oxidation such as acidic electrolysis bath such as sulfuric acid, oxalic acid, phosphoric acid
Pass to certain additional positive current in liquid, aluminum alloy surface can be formed one layer with amorphous alumina be mainly form, thickness
Up to tens microns of hard coating.Anode oxide film have double-layer structure, internal layer is thin and compact, claim barrier layer, outer layer be compared with
Thick porous layer, this porous layer have excellent adsorption capacity, often as the bottom of aluminium coloring or the mistake of outer overcoat layer
Cross layer, but anti-corrosion capability, weatherability, stain resistance, etc. cannot all reach requirement, therefore consider from practical application, aluminium sun
The micropore of pole oxidation film must be closed.The anode oxide film of non-sealing of hole makes to be exposed to due to the area in a large amount of micropore holes
The effective surface area of workpiece or sample in environment increases by tens times and arrives hundreds of times, and corresponding corrosion rate also greatly increases thus
Add.Therefore anodizing of aluminium film is in addition to individual such as abrasion-resistive hard oxidation films, from corrosion resistance and stain resistance consideration is improved, all
It must carry out sealing pores.
Industrial relatively common common sealing of hole operating method has 4 kinds: high temperature hole sealing, cold seal hole, medium temperature sealing of hole, organic matter
Sealing of hole.
High temperature hole sealing, high temperature hole sealing are called boiling water sealing hole, are the oxidation film (Al by aluminum products surface2O3) hydration it is anti-
Vigorous nurse body, vigorous nurse body good corrosion resistance should be generated, and the expansion of oxidation film molecular volume seals oxide-film micropore when hydration reaction
It closes.Cold seal hole, cold seal hole do not need to heat, and can operate at room temperature, so being called room temperature sealing of hole.Generally use fluorine in cold seal hole
Change nickel, relies primarily on the nickel ion of positive divalent and the fluorine ion of negative one valence.
Medium temperature sealing of hole, medium temperature sealing of hole refer to a kind of temperature of the sealing of hole sealing of hole between the two in high temperature hole sealing and cold seal hole
Technology, main hole sealing agent are nickel acetate, and stability is good, is easy to control.
Organic matter sealing of hole coats one layer of organic polymer coating on aluminium material oxidation film.
At present in aluminum alloy anode oxidative work-up technique, in order to reduce the voidage and adsorption capacity of anode oxide film,
It is a large amount of using low temperature pore sealing agent mild in containing, the hole sealing agent sealing of hole is fast, easy to operate, dyestuff when sealing of hole can be effectively prevented
It leaches, impurity permission is big, and sealing of hole weightlessness is minimum, and properties of product and appearance are attained by requirement.But due to nickeliferous metal
Gadget is contacted with human skin for a long time, and can dissociate Ni out under the effect of human body sweat stain2+, disturb skin and itch, induce Allergic contact
Dermatitis is forbidden to use by many countries, and has put into effect relevant limitation standard, thus exploitation can volume production without nickel hole-sealing technology at
For the task of top priority.There are many relevant report about no nickel hole sealing technology, but comparative maturity: fluotitanate without nickel medium temperature
Hole sealing agent.This hole sealing agent is potassium fluotitanate 5-10g/l, cyclohexanone 0.05-0.15g/l, isoamyl alcohol 0.05-0.15g/l.The envelope
Temperature of hole agent when carrying out sealing of hole is 55-65 DEG C, and the processing time is 1.0-1.5um/min.Although the hole sealing agent solves
Injury of the nickel to human body and the pollution to environment, but coating sealing reagent has that high temperature heat-resistant corrosivity is poor.
