Description
Technical field
The present invention relates to anti-corrosion of metal field, specifically a kind of high-hardness, wearable corrosion-inhibiting coating and preparation method thereof.
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.
Existing corrosion-inhibiting coating disclosure satisfy that the requirement for anticorrosion of outdoor metal guardrail substantially, but guardrail holds in actually using
It is vulnerable to scraping, corrosion-inhibiting coating is vulnerable to destruction, influences antiseptic effect, causes the accident.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided a kind of high-hardness, wearable corrosion-inhibiting coating and its preparation side
Method, compared with existing anti-corrosive metal coating, there is hard high-wearing feature energy, service life length.
The present invention includes the component of following mass fraction：
Alumina particle 5-8
Chrome oxide particle 5-8；
Polyvinyl alcohol 3-15；
Compound α-ceramic 5-8；
DAAM 5-10；
Polyacrylate material 2-7；
Deionized water 30-50.
The particle diameter of described alumina particle is 50-100 nanometers.
The particle diameter of described chrome oxide particle is 50-100 nanometers.
Preparation method of the present invention is as follows：
Ball mill ball milling will be put into after alumina particle, chrome oxide particle and compound α-ceramic drying, makes chromium oxide and oxygen
Change the size controlling of aluminium in 50-100 nanometers, then add polyvinyl alcohol, DAAM, polyacrylate material and go
Ionized water, maturation process is carried out after said components are mixed, then spray, brush or be immersed in substrate surface, in base after deposition
Material surface forms coating.
Described drying course is in an oven under conditions of 150-180 degrees Celsius, to dry 2-14 hours.
Beneficial effect of the present invention is：It is of the invention that there is hard high-wearing feature energy compared with existing anti-corrosive metal coating,
Service life is grown.
