Abstract
The invention discloses a kind of modified Portland compound binding agents and the preparation method and application thereof, wherein modified Portland compound binding agent is included and is modified using the presoma of different silicon, boron, aluminium, titanium, zirconium to alkali silicate, to which modified Portland be made, and to its aquation, modified Portland compound binding agent is obtained.For the present invention compared with existing silicate binder, cure shrinkage is small, can be applied on metal base or other inorganic non-metallic substrates directly as binder or coating；Heat-resistant limit is higher, and by adding the doping vario-property of non-element silicon, such as aluminium, titanium and zirconium, heat resistance is higher.
Description
Technical field
The present invention relates to anti-corrosion coating materials binder field more particularly to a kind of modified Portland compound binding agent and its
Preparation method.It includes high-temperature resistant coating that the binder, which can be applied to, ceramic coating, ceramic material, high temperature kiln material for repairing, is determined
The fields such as shape or unshape refractory, flame retardant coating, high-temperature Resistance Adhesives, it is long to be particularly suitable for metal material under hot environment
The corrosion protection of phase.
Background technique
The industry of requirement with to(for) the material of operation, structure etc. under hot environment is higher and higher, is developed various
The high-temperature protection coating for anti-corrosion of metal of various kinds is applied from traditional signal layer coating to MULTILAYER COMPOSITE gradient coating
Layer material is assigned by simple metal material ceramic coating till now and the compound coating of metal material and ceramic material
Coating material anticorrosion, anti-oxidation protection and certain specific functions etc..
Ceramic heat-barrier coating technology of the coating material by simple coat of aluminide till now, construction method also conform to the principle of simplicity
The low-voltage plasma spraying of single dipping aluminium, heating aluminizing technology to today, physically or chemically the methods of vapor deposition.Although this
Coating high temperature resistant that a little materials and technique are prepared, anti-oxidant, Corrosion Protection are all very superior, but its raw material and construction
Equipment cost is high, and large-area construction is difficult, does not still have practical significance for large-scale industrialization application.Based on above-mentioned
Reason can form a film under lower temperature even room temperature and be resistant to the binder of high temperature by traditional aerial spraying
As the bottleneck problem of high temperature protection field development, this also results in the interest of numerous researchers.
Currently, the binder that can tentatively meet conditions above mainly has several major class such as phosphate, colloidal sol and silicate.One
As common phosphate binders have aluminium dihydrogen phosphate, magnesium dihydrogen phosphate and a zinc dihydrogen phosphate, it is stronger it is acid (pH=1~

Agent, with the raising of modulus, its brittleness becomes larger, and storage stability is deteriorated, cure shrinkage also becomes larger, and easily opens in film forming procedure
It splits, but its normal temperature cure performance and water resistance performance are greatly promoted, for manufactured coating material, because of cure shrinkage
Promotion caused by problem of Cracking be hard to avoid.
In consideration of it, all kinds of method of modifying are developed, the method for modifying as disclosed in 1362940 A of patent CN is addition
Nano-powder and polysiloxanes are modified, and are improved its storage stability, can be stabilized three months or more, and apply made of it
Layer material has acidproof, weather-proof and high temperature resistance.As 104177877 A of patent CN passes through addition silicon dioxide fibre and silicon
It is sol-gel modified, so that its manufactured coating material is had both high temperature resistance and flexibility, is not referred in above-mentioned patent and use such
When binder the problem of Cracking of coating material film after cure shrinkage this how to solve.Such as application No. is
Lotion is added in the patent of CN201610781579.9 to improve the flexibility of film and cohesive force while prevent from flocculating, this is specially
Though the solution problem of Cracking that benefit can be more safe, leads to the heat resistance sharp fall of coating because joined lotion.
Therefore, develop be resistant to high temperature and in the curing process indehiscent silicate binder have important reality
Border meaning and vast market prospect.
