Abstract
The present invention provides a kind of preparation method of composite material for nanometer injection molding, it in turn includes the following steps :-direct current energization corrosion-secondary dipulse energization corrosion-post-processing-drying-nanometer injection molding of-two step pre-etching of mechanical pretreatment, and corrode in galvanization with ultrasonic wave added, the substrate of composite material is one of aluminium alloy, titanium alloy, magnesium alloy or stainless steel, which can be applied to the preparation of mobile communication terminal shell.
Description
Technical field
The present invention relates to field of metal surface treatment, more particularly, to one kind using stainless steel, titanium alloy, aluminium alloy as substrate
The preparation method and application of composite material for nanometer injection molding.
Background technique
Japanese great achievement plastics (Taiseiplas) Co., Ltd. has invented nanometer forming technique (NMT), the skill in 2002
Art is that metal and resin integrated molding can be widely used in metal and the integrated nanometer forming technique of plastics thin light, just to
On the shell for the mobile electronic product taken, such as computer terminal, cell phone.
Now in the art, the treatment process of NMT includes process as follows: the metal for needing to combine is carried out at lye
Reason, sour processing, weak acid treatment are dried after washing with water again completely, are molded.After processing nothing will be formed in metal surface
The micropore that several apertures is about 20nm, that is to say, that may be considered and formd on metal surface after treatment very much
The resin of small concaveconvex structure, injection enters in these concaveconvex structures, generates anchoring effect, in other words: metal base is first
The impurity such as the grease on surface are removed by alkali cleaning, the metal oxide on surface is removed by pickling and etch nanoscale hole hole；
It is handled again by T and etches smaller nanoscale hole hole；Metal after washing and drying is clamped in mold and plastics note
Modeling reaches integral structure, is obtained by above-mentioned record, the key technology of NMT be processing for substrate and nano injection at
The operation of type, and pass through pickling and remove the metal oxide on surface and etch nanometer or micron order hole often will appear big face
Product excessive erosion, can not only form effective duct, can occur plane dissolved corrosion instead, heavy losses substrate metal, in addition,
The duct that acid corrosion is formed is concentrated mainly on nanoscale, since duct is too small, is unfavorable for the flowing injection of resin, and easy to form
Gas barrier is unfavorable for contact of the resin with substrate, therefore the nanometer injection molding of metal base faces following problem: (1) base at present
Material etch pit is small, and duct depth as shallow, cannot effectively penetrate through between duct；(2) since duct forms poor, it is unfavorable for resin
Attachment, and cause the binding force of resin and substrate weaker, the binding force otherness between resin and substrate is larger, in conjunction with uniformity
It is poor.
Summary of the invention

Magnesium, iron oxide make substrate metal keep clean, smooth, lay one to form more uniform etch pit during subsequent corrosion
Fixed basis.
Two step pre-etching, i.e. first acid processing, rear caustic corrosion are used in preprocessing process, the pretreatment with the prior art exists
Obvious difference, firstly, the phosphoric acid main function of strong acid on the surface of magnesium, titanium, stainless steel as in is not corrosion, but
One layer of relatively stable chemical composition coating is formed, is occurred in oxidation reaction process in phosphoric acid and metal, three H in phosphoric acid+It is slow
On The Drug Release avoids metal base by excessive erosion (excessive erosion that hydrochloric acid is frequently present of large area), in addition, the chemical composition coating is in acid
Property under the conditions of in dissolution and and precipitating dynamic equilibrium in, if second step continued using other caustic acids corrode oxygen
Change film, although feasible, effect is poor, by exploring, it is found that the chemical composition coating is double property, it can be dissolved in acid, and can be with
It is dissolved in alkali, under alkaline condition, it is aperture that the place of chemical conversion film surface existing defects can be corroded by lye, and the aperture is in base
The distribution on material surface and density are all much higher than the pre-etching effect of similar low-kappa number.
The main purpose of direct current energization corrosion process is that longitudinally perpendicular etch pit is formed in substrate surface, and cardinal principle is
By aggressive chloride ion attack metal oxide film surface, and in H+Synergistic effect under, (direct current is logical for the formation in accelerated corrosion hole
Galvano-cautery is the model machine process for constantly losing electronics, that is, has oxidation to have the process of corrosion again), and during this, deep-etching
Key reaction is remained, this easily causes longitudinally perpendicular etch pit too drastic or uneven, therefore in order to reduce deep-etching

It cannot be replenished in time again constant with sulfuric acid in retaining hole and concentration of nitric acid, therefore affect duct inner wall uniformity.Direct current simultaneously
Gas or other products are constantly generated in electrochemical corrosion course, are adsorbed on the inner surfaces of pores of hole wall or hole wall, and part hinders
Hindered the duct of hole wall protrudes into or is difficult to happen being connected between the duct of hole wall, and electrical pulse caustic solution is used to introduce
Pulse current, after corroding a period of time, stop for some time allows corruption of the reaction product to outside hole external diffusion and hole
Erosion acid is to pore diffusion, to fill up consumption.In addition, dipulse electric current is compared with single-pulse current, in a wave period not only
There are the turn-off times, and there are negative currents, and the average current value that power supply exports in electrodeposition process is constant, but due to
It is positive and negative to be conducive to acid solution to all there is the turn-off time and constantly impact and discharge in aluminium surface, it is further formed on hole wall rotten
Borrosion hole, therefore, secondary dipulse, which is powered, corrodes the etch pit of acquisition, and duct is uniform, is mutually communicated, and is conducive to the attachment of resin.
In addition, forms of corrosion of the invention can also select primary exchange energization corrosion and secondary AC to be powered corrosion to gold
Belong to substrate handled, at this stage for, final conclusion there is no for the mechanism model of AC corrosion metal, but have following thing substantially
Real, alternating current can accelerate metal anode course of dissolution, and the destruction of the metal erosion as caused by alternating current causes than direct current electro ultrafiltration
It is light, and increase in intensity with a-c cycle and reduce, as just exploration in the present invention.
