Description
Technical field
The present invention relates to a kind of coating, particularly to a kind of high temperature resistant zinc-rich paint preventing metal erosion and preparation side thereof
Method, belongs to painting field.
Background technology
The corrosion of metal is modal etch state.During corrosion, the interface of metal there occurs chemistry or electrochemistry
Heterogeneous reaction, makes metal proceed to aoxidize (ion) state, and this can significantly reduce the mechanics such as the intensity of metal material, plasticity, toughness
Performance, destroys the geometry of hardware, increases the abrasion between part, deteriorates the physical properties such as electrical and optical, and shortening sets
In standby service life, even cause the catastrophic failure such as fire, blast.
According to statistics, the iron and steel being directly lost due to corrosion every year, account for 1/4th of iron and steel annual production.People pass through
Various modes delay the corrosion rate of iron and steel, as improved base material, selecting anticorrosive, the increase coat of metal, interpolation inhibition
Agent, employing electrochemical protection.People suppress or stop corrosion of metal by adding other materials in simple metal, obtain
Success in various degree.But the trace substance added in ferrum may accelerate the speed of corrosion, and employing is less likely to occur
The material of corrosion solves the shortcoming of etching problem and is that, compared with original metal, its physical property has lacked, or
Person causes cost to increase due to the cost of alloy.The most the most frequently used anti-corrosion mode is exactly to needing metal to be protected additional
The individual face coat (or coating) having tolerance.The material that this type coating is used is different, but conventional be coating.
Common coating is the simplest covers isolation air, and antisepsis is the strongest.
The present invention, by developing a kind of rich, high temperature spelter coating, is coated in steel surface, thus is greatly prolonged making of steel construction
Use the life-span.This paint uses Lithium metasilicate to be base material, by Lithium metasilicate and zinc powder cross-linking reaction film forming under certain condition, Lithium metasilicate
Aqueous solution is water white transparency or the liquid in opalescent, nontoxic, do not fire.Lithium silicate aqueous solution has and has the glass of water-wetted surface
The characteristic of the surface reaction film forming of glass, iron and steel, aluminum and fiber etc., more than 60 DEG C can be carried out, and temperature is the highest, react the fastest.Make
For paint binder, available water as solvent, the film of formation, there is heat-resisting, radiation hardness, the performance such as nontoxic.The normal potential of zinc is relatively
Iron and steel is low, and when corrosive medium penetrates into, iron and steel forms galvanic element with zinc powder, and zinc powder loses electronics, iron and steel as the negative pole of galvanic element
Obtain electronics as positive pole and obtain protection.It addition, the anion binding in the zinc ion being dissolved out and corrosive medium and shape
Become basic zinc salt and zinc-iron double salt, fill up the crack of film, and reach to isolate etch-proof purpose.This coating property is stable,
Applied at elevated temperature not demoulding, has good resistance to elevated temperatures.
Summary of the invention
It is an object of the invention to provide a kind of high temperature resistant zinc-rich anti-corrosive paint and preparation method thereof, for realizing this purpose,
This coating includes the raw material of following mass fraction:
Lithium metasilicate 5%-10%；
Ludox 20%-50%；
Poly alkyl alcohol oxirane ether 5%-10%；
Silane coupler 5%-10%；
Silicone acrylic emulsion 20%-30%；
Super-fine zinc dust 20%-30%；
The preparation method of a kind of high temperature resistant zinc-rich anti-corrosive paint comprises the steps:
(1) pouring a certain amount of Lithium metasilicate solution into vessel in heating, temperature controls at 50-70 DEG C；
(2), under ceaselessly stirring, it is slowly added dropwise the Ludox of metering so that it is be sufficiently mixed；
Certain poly alkyl alcohol oxirane ether measured and silane coupler, high-speed stirred is added the most again in container；
(4) stop heating, when temperature is down to room temperature, add silicone acrylic emulsion；
(5) last add appropriate super-fine zinc dust, continuously stirred 10-15 minute a kind of high temperature resistant zinc-rich anti-corrosive paint.
The present invention has following advantages and a characteristic:
(1) this has coating high-temperature behavior good；
(2) good mechanical property, easy construction；
(3) technique is simple, low cost.
