Abstract
The present invention relates to a kind of aluminium workpiece surface nano aperture processing method for nanometer injection, including：Oil removal treatment is carried out to aluminium workpiece surface；The aluminium workpiece surface cleaned with water after oil removal treatment, then aluminium workpiece surface is once neutralized；The aluminium workpiece surface cleaned with water after once neutralizing, alkaline etching processing then is carried out to aluminium workpiece surface, after secondary neutralization is carried out to aluminium workpiece surface；Using the aluminum component after secondary neutralization as anode, progress primary electrochemical corrosion treatment in the first acidic electrolysis pond is placed in；Using the aluminum component through primary electrochemical corrosion treatment as anode, progress making active materials for use in secondary electrochemical corrosion treatment in the second acidic electrolysis pond, after water cleans, drying are placed in, you can.Compared with prior art, the obtained nano aperture distributing homogeneity of the inventive method is good, and the surface of nano aperture is mellow and full smooth, and hole size homogeneity is good, may be such that resin is easily accessible, and can be effectively improved nanosizing combination effect of the aluminum component with plastics.
Description
Technical field
The invention belongs to materials processing technology field, is related to a kind of aluminium workpiece surface nano aperture processing method, especially relates to
A kind of and aluminium workpiece surface nano aperture processing method for nanometer injection.
Background technology
Nanometer forming technique（NMT, i.e. Nano Molding Technology), it is metal with plastics with nanometer technology knot
The engineering method of conjunction, first by metal surface after nanosizing is handled, plastics direct injection allows metal and plastics in metal surface
Can be not only able to take into account metal appearance texture with integrally formed, the design of product construction part can also be simplified, allow product it is lighter, it is thin,
It is short, small and more cost effective compared with CNC engineering methods.Effective combination for metal and plastics, nanometer forming technique can substitute at present
Conventional insertion is projected or zinc-aluminium, magnalium die casting, and can providing one kind, there is price competition, high performance gold to mould integration and produce
Product.Japan uses NMT technologies many years ago, and the technology has simplified processing procedure process, shortening man-hour and elevating mechanism performance etc. excellent
Point, production cost and high bond strength are reduced, and the utilization rate of consumables associated therewith is greatly reduced.Japanese great achievement plastics possess NMT
Patent.When starting, aluminium and hard resin are simply subjected to integrated molding, this later NMT technology is further changed
Enter, can apply to the metals such as magnesium, stainless steel, titanium and hard resin integrated molding.And further develop between metal
Combination technology, it is expected there is new purposes in the composite article of metal and resin.
Corrode in existing nanometer forming technique frequently with amine substance, the cavity that aluminium workpiece surface is formed is too small, and resin is difficult
Enter nano level hole to be directly molded, this reduces the bond strength of aluminum component and resin, tensile resistance is poor, simultaneously
The combination of resin and aluminum component is mainly to rely on amine groups, and the species of the resin used is very limited.At present, the technology can use
Resin there was only tetra- kinds of resins of PPS, PA, PPA, PBT, practical ranges are narrower, and use amine substance be it is poisonous,
Volatile material, it is unfavorable for keeping the safety in production, the feature of environmental protection is poor.For example, the A of Publication No. CN 103286996 patent discloses
A kind of cushioning liquid, aluminium alloy are dipped into pH=10-13 composite buffering solution, and the number of immersion is 2 to 20 times, Ke Yi
The oxide-film extexine of aluminium alloy forms etch pit and obtains surface treated aluminum alloy base material, and composite buffering solution is can
The mixed solution of soluble phosphoric acid hydrogen salt and water soluble alkali.Although this method can prepare good nano aperture structure, aluminium closes
Gold is good with resin-bonded power, but contains P elements and highly basic in preparation, and its is big for environment pollution.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of energy consumption is small, environment is friendly
Good, easy to operate, economic and practical is good, may be implemented in the uniform nanoscale hole hole of aluminium workpiece surface, can be effectively improved aluminum component and modeling
The aluminium workpiece surface nano aperture processing method for being used for nanometer injection of the nanosizing combination effect of material.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of aluminium workpiece surface nano aperture processing method for nanometer injection, this method specifically include following steps：
Step（1）：Oil removal treatment is carried out to aluminium workpiece surface；
Step（2）：With water cleaning step（1）Aluminium workpiece surface after oil removal treatment, then aluminium workpiece surface is once neutralized；
Step（3）：With water cleaning step（2）Aluminium workpiece surface after once neutralizing, alkaline etching processing then is carried out to aluminium workpiece surface,
After alkaline etching processing terminates, secondary neutralization is carried out to aluminium workpiece surface；
Step（4）：With step（3）Aluminum component after secondary neutralization is anode, is placed in the first acidic electrolysis pond and carries out once electricity
