Description
Technical field
The present invention relates to high temperature anti-oxidation coating technical fields, and in particular to a kind of modified white graphite alkene compound anti-oxidation painting
Material and its preparation.
Background technology
Steel products are in carrying out a series of heat treatment process, and steel surface is easy under the conditions of atmospheric environment high temperature
Oxidative phenomena is generated, while with the oxidation of alloying element in iron structure, this brings a series of as used to steel products
The problems such as reduced performance, energy consumption increase, seriously affects steel products quality and service life.Up to the present, whole world steel
Industry, because steel oxidation causes product loss to have increased to 15%, causes the huge wasting of resources in heat treatment process.
Therefore taking measures, surface oxidation has been that people urgently solve the problems, such as to reduction steel products in a high temperauture environment.
Currently, what is generally used has vacuum method, protective atmosphere method, high temperature anti-oxidation coating etc. to prevent metallic high temperature from aoxidizing.
Vacuum method is that metal material is carried out to heat treatment in vacuum environment, reduces contact of the metal product with oxygen, prevents
The progress of oxidation on metal surface.But the vacuum equipment that this method uses is costly, requires product size and operating personnel requires very
Height limits its application；Protective atmosphere method carries out in the non-real air atmosphere of few oxygen, particular by be filled with nitrogen, methane,
The protective gas such as hydrogen and inert gas drive the oxygen in environment away, reduce steel surface and contact to reach anti-with oxygen
The purpose of oxidation, but the complex process, equipment is also costly, while protective atmosphere pollutes the environment, and is not suitable for making on a large scale
With.Therefore it is that high-temp antioxidizing paint carries out high-temperature oxidation resistant guarantor during heat treatment to metal material generally to use at present
Shield, principle are before heat treatment, high temperature anti-oxidation coating to be coated in metal surface, when high-temperature heat treatment coating softening reach
Molten condition forms fine and close protective film in metal surface, and high-temperature gas is prevented to reach a high temperature to matrix permeability anti-oxidation effect
Fruit.What application was more currently on the market is addition boron carbide, boron nitride high-temperature antioxidant coating, but it is 1000 DEG C to limit to temperature,
When temperature is more than 1000 DEG C, boron carbide or boron nitride can form higher vapour pressure, and evaporation rate is fast, and anti oxidation time is caused to have
Limit.Therefore it is industry people to develop a kind of high temperature anti-oxidation coating that can stablizes under more harsh temperatures environment to expand market to apply
The target that member pursues always.
Invention content
In view of this, it is necessary in view of the above-mentioned problems, a kind of modified white graphite alkene compound anti-oxidation coating of offer and its system
It is standby.
To achieve the above object, the present invention takes following technical scheme：
The modification white graphite alkene compound anti-oxidation coating of the present invention, including：Liquid phase and inoganic solids phase；
The liquid includes mutually in parts by weight：20~50 parts of matrix resins, 5~30 parts of Ludox, 5~30 parts of couplings
Agent, 20~60 parts of deionized waters；
The inoganic solids include mutually in parts by weight：0.1~10 part of modified white graphite alkene, 5-20 parts of glass powders, 10~
40 parts of ball-aluminium oxides, 5-30 parts of aerosils.
Further, in the liquid phase, matrix resin includes acrylic resin, aqueous polyurethane, acrylic acid-organosilicon
At least one of resin；
The coupling agent includes one kind in Silane coupling reagent KH-570, KH-590, tetrabutyl titanate.
Further, in the inoganic solids phase, modified white graphite alkene is 5~10 layers of white graphite alkene；
A diameter of 50~200nm of the ball-aluminium oxide；
A diameter of 10~the 100nm of aerosil.
The present invention is modified the preparation of white graphite alkene compound anti-oxidation coating, including：It weighs respectively in parts by weight a certain amount of
Matrix resin, Ludox, after coupling agent and deionized water, be added sequentially to room temperature in homogenizer and be mixed, then claim
A certain amount of ball-aluminium oxide, aerosil, glass powder and modified white graphite alkene are taken, and is added sequentially to homogenizer
After middle heating is mixed, then through 30~240min of planetary ball mill ball milling obtain final products；
The homogenizer processing temperature is 40~100 DEG C, mixing time is 10~60min.
Further, the white graphite alkene surface modifying method is：Select 5-10 layers of 0.3% oleyl amine water of white graphite alkene
Solution, long-chain borine, neopelex ethanol solution, brocide ethanol solution or polyethylene oxide alkane
Base alkylolamides aqueous solution soaking 24 hours, must be modified white graphite alkene after centrifuging, being dried in vacuo.
Compared with prior art, beneficial effects of the present invention are：
5~10 layers of modification white graphite alkene has the stratiform of similar graphite because it is single layer or few layer hexagonal boron nitride
Structure, 900 DEG C of oxidation resistance temperature, 2000 DEG C of high temperature resistant, and have good separation gas performance.When atomic layer is less than ten layers,
Lamella arrangements are compact, uniform, and barrier sheet number of layers is more, and gas detours in the coating, and path is elongated, and a small amount of addition can be very
Good blocking gas passes through；In high temperature harsh environment, compared with traditional boron nitride high-temp. antioxidation coatings, repaiied through surface
The white graphite alkene of decorations has better compatibility, densification to be scattered in coating with matrix, and the white graphite alkene piece under same weight
The number of plies is more, can be bound more closely the ability high temperature that is stronger, therefore being modified through white graphite alkene of isolation oxygen between layers
The oxidation resistance of antioxidant coating is stronger.
The modification white graphite alkene compound anti-oxidation coating of the present invention, it is strong to bear 1800 DEG C of high temperature, oxidation resistances, simultaneously
There is prodigious application value this substantially prolongs by the service life of protection materials with preferable adhesive force and weatherability.
