Abstract
The invention provides a kind of guardrail wires rare earth corrosion-inhibiting coating, include the component of following mass fraction：Rare earth aluminium alloy powder 13；Siloxanes 10 20；Compound α-ceramic 58；Carborundum 13 15；Deionized water 20 65.The present invention replaces rare earth yttrium with the relatively relatively inexpensive rare earth aluminium alloy of low content price, on the premise of antiseptic property is suitable, significantly reduces cost.
Description
Technical field
The present invention relates to anti-corrosion of metal field, specifically a kind of guardrail wires rare earth corrosion-inhibiting coating.
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.
The best corrosion-inhibiting coating of existing most widely used effect is combined high temperature ceramic anticorrosive paint, using high temperature resistant fluosilicic
The retrofit under closed high temperature such as solution, rare earth yttrium micro mist, compound α-ceramic, carborundum forms, and heatproof can reach
To 1600 DEG C, soda acid long-term corrosion environment can be widely used in.But its cost is higher, can not apply civilian in guardrail wires etc.
Field.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided and a kind of guardrail wires rare earth corrosion-inhibiting coating is and existing dilute
Native corrosion-inhibiting coating is compared, and rare earth yttrium is replaced with the relatively relatively inexpensive rare earth aluminium alloy of low content price, suitable in antiseptic property
On the premise of, significantly reduce cost.
The present invention includes the component of following mass fraction：
Rare earth aluminium alloy powder 1-3；
Siloxanes 10-20；
Compound α-ceramic 5-8；
Carborundum 13-15；
Deionized water 20-65.
Described rare earth aluminium alloy Al-RE-Cu-Si-Mn-Ni-Mg casting alloys.
Beneficial effect of the present invention is：Compared with existing rare earth corrosion-inhibiting coating, with relatively relatively inexpensive dilute of low content price
Native aluminium alloy replaces rare earth yttrium, on the premise of antiseptic property is suitable, significantly reduces cost.
Embodiment
With reference to embodiment, the invention will be further described.
The present invention includes the component of following mass fraction：
Rare earth aluminium alloy powder 1-3；
Siloxanes 10-20；
Compound α-ceramic 5-8；
Carborundum 13-15；
Deionized water 20-65.
Described rare earth aluminium alloy Al-RE-Cu-Si-Mn-Ni-Mg casting alloys.
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.
