Abstract
The invention provides a kind of Metal surface anti-corrosion processing method, including sanding and polishing, high pressure water washing, drying, coating adhesive linkage and coating corrosion-inhibiting coating, temperature control during by coating corrosion-inhibiting coating, the compactness connected between coating and substrate is improved, greatly extending the service life of coating.
Description
Technical field
The present invention relates to anti-corrosion of metal field, specifically a kind of Metal surface anti-corrosion processing method.
Background technology
Metal material is damaged by the effect of surrounding medium, referred to as metal erosion (Metallic Corrosion).Metal
Corrosion be most common etch state.During corrosion, there occurs chemistry or electrochemistry heterogeneous reaction on the interface of metal, make gold
Category is transferred to oxidation（Ion）State.This can significantly reduce the mechanical properties such as the intensity, plasticity, toughness of metal material, destroy metal
The geometry of component, increase the abrasion between part, deteriorate the physical property such as electrical and optical, shorten the service life of equipment,
Even cause the catastrophic failures such as fire, blast.
The metal protection method used at present can be roughly divided into three classes：One kind is to carry out anodized, i.e., in metal
Surface forms one layer of tens microns of thick anode oxide film, but because anode oxidation process power consumption is big, and electrolyte is molten
Liquid is seriously polluted, it is difficult to handles, is restricted using its application；Second class is chemical composition coating, i.e., is immersed in metal parts
In the solution of definite composition, one layer of chemical composition coating is formed by chemical reaction at a certain temperature, it is now most widely used
Be chromate chemical oxidation, but chromate is a kind of carcinogenic toxicant, and world environments protective tissue, which has pointed out limitation, to be made
With chromate and other contain chromate compound；3rd class is organic coating, i.e., coats one layer of organic coating in metal surface, with
Improve the outward appearance and physical and chemical performance of metal.
After the completion of present intermetallic composite coating, generally go through simple cleaning and be directly surface-treated, its surface drop or
Impurity particle is liable to stick between metal and coating, is caused to connect between coating and substrate not closely, is easily come off.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided a kind of Metal surface anti-corrosion processing method, utilizes this hair
Bright technique anticorrosive coating, is connected between coating and substrate, greatly extends the service life of coating.
The present invention comprises the following steps：
1）The metal machined is subjected to surface sanding and polishing；
2）Shower cabinet high pressure water washing 1-3 minutes are put into, hydraulic pressure is more than 300 pas；
3）It is sent into baking oven under conditions of 150-180 degrees Celsius, dries 2-14 hours；
4）Adhesive linkage is coated in metal surface, 5-10 minutes are stood after coating；
5）Corrosion-inhibiting coating is coated on adhesive linkage, 15-30 minutes are preheated under 200-300 degrees Celsius, it is then Celsius with per minute 5
The speed of degree is heated up, until temperature reaches 450 degrees Celsius, is incubated 3-5 hours.
Beneficial effect of the present invention is：Using the technique anticorrosive coating of the present invention, connected between coating and substrate, greatly
Extend the service life of coating.
Embodiment
With reference to embodiment, the invention will be further described.
The present invention comprises the following steps：
1）The metal machined is subjected to surface sanding and polishing；
2）Shower cabinet high pressure water washing 1-3 minutes are put into, hydraulic pressure is more than 300 pas；
3）It is sent into baking oven under conditions of 150-180 degrees Celsius, dries 2-14 hours；
4）Adhesive linkage is coated in metal surface, 5-10 minutes are stood after coating；
5）Corrosion-inhibiting coating is coated on adhesive linkage, 15-30 minutes are preheated under 200-300 degrees Celsius, it is then Celsius with per minute 5
The speed of degree is heated up, until temperature reaches 450 degrees Celsius, is incubated 3-5 hours.
Concrete application approach of the present invention is a lot, and described above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise without departing from the principles of the invention, some improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
