Description
Technical field
The present invention relates to chemical material technical field, more particularly to a kind of corrosion-resistant ceramic coating composition and its preparation side
Method.
Background technology
With continuing to develop for offshore oil, port and pier, water-power plant and shipping industry, as drilling well winning apparatus,
Drilling platforms, conveyance conduit etc., due to submergence throughout the year in the seawater, it is easy to by tidewater and fluctuation and splashing, and by
Marine biological erosion, therefore, develop a kind of the heavy anticorrosive material of application can have great importance in ocean and fresh water.
China current most of large high-temperature wet tanks or pipeline, use metal pipe material, such as carbon steel, stainless steel material more
Matter.It is general to add lining in these tank bodies, inner-walls of duct or directly coat coating in inwall, to improve the resistance to of these equipment
High temperature, Corrosion Protection, extend its service life.The tank body or inner-walls of duct of stainless steel or carbon steel material frequently with liner protect
Shield mode is mostly to use composite, but its complex process, cost are high, and popularization is low, and what is used at present more generally selects
With suitable coating in inner wall surface formation protective coating, this kind of measure implements i.e. simple and effective, and use cost is again low.
With oil field into the later stage exploit, aqueous, silt content raising, metal pipe line, the wear-resisting loss of equipment, corrosion-resistant feelings
Condition more allows of no optimist.And the corrosion of some oil field sulfide hydrogens, aphthenic acids and carbon dioxide is extremely serious, cause equipment corrosion
Perforation is frequent, has a strong impact on the safety and stability production in oil field；Although taking some measures, for example, making in oil well and equipment

Still the generation of corrosion is difficult to avoid that in environment, huge loss is brought to oil field.Some hydrogen sulfide containing oil fields, because of release
Go out poisonous gas, cause casualties.Solve the etching problem of acid-containing raw oil, the development to petroleum industry, safety and stability
Production is significant.Therefore, for such Basic Geological and operating mode situation, it is necessary to disposably solve acid resistance corrosion and impact
The problem of property.
In terms of acid-proof resin, comparatively the excellent resin of acid resistance is chlorinated polyethylene rubber, but chlorination is poly-
Ethylene rubber has the drawback that paint film is crisp, in the case of impact-resistant operating mode, it is easy to peel off, it is difficult to which satisfaction is actually needed.One
Individual thinking is exactly to add flexible resin in phenolic resin to carry out blending and modifying.But general flexible resin, such as thermoplastic poly
Due to there is ester bond in the molecule, under sour hydrionic catalytic action, ester bond easily occurs for urethane, polyadipate series plastics
Fracture, influences the service life of material.Meanwhile, also there is the consistency problem between resin and epoxy resin.Utilize cosolvent
Although scheme can solve the compatibility before construction, paint film is in different drying stages after construction, it will phase occur
Separation.The change of this microstructure will influence the antiseptic property of paint film.Even if in addition, by chlorinated polyethylene rubber and poly- second
Alkene butyral, which is mixed, is made coating, and it still suffers from the not enough defect of corrosion resistance in ocean and fresh water during application.
