Abstract
The present invention relates to the production technique of wear resistant anticorrosive paint, particularly to super critical boiler wear resistant anticorrosive paint and a production method thereof. The wear resistant anticorrosive paint is formed in a mode that nano-grade alumina, titanium carbide, silicon oxide, zirconium oxide, pyrophyllite powder, metal aluminum powder, calcium oxide, magnesium oxide, potassium oxide and sodium oxide are adequately stirred and evenly mixed to a slurry material shape with high-temperature binding agent to be produced after mixed and milled into balls. The aim of the present invention is to provide a super critical boiler wear resistant anticorrosion paint and a production method thereof having high combined strength of a coating, good wear resistant and anticorrosive performance and stable performance. Compared with the prior art, the coating is fine and compact, can not crack, can not bubble and has high heat conduction coefficients after the paint is used, and the service life of ' four pipes ' can be enhanced from one to two overhaul periods. The present invention can be widely applied to the high temperature application field of boiler pipelines of a coal-fired power plant, chemical equipment, metallurgical industry, etc.
Description
Affiliated technical field
The present invention relates to the production technology of wear resistant anticorrosion paint, relate in particular to a kind of Corrosion-resisting coating of anti-friction supercritical boiler and its preparation method.
Background technology
The attrition and attack of coal-fired plant boiler is the significant problem of puzzlement safe operation of power plant.Super critical boiler is often referred to more than the 224.56 table normal atmosphere, vapor temperature 540-650 ℃ large coal-fired boiler, and the generated energy that such boiler provided accounts for more than 80% of national gross generation.Because super critical boiler vapor temperature flue-gas temperature height, the position that the generator tube system is huge or the like goes wrong is many.Wherein, boiler " four pipe " (water wall tube, superheater tube, reheater tube, economizer tube) is modal safe operation accident because of the high temperature corrosion of the high-temperature erosion abrasion that is subjected to flying dust and flue gas causes the tube wall attenuate to produce pipe explosion accident.So the high temperature erosion problem is an important factors that influences the normal operation in its coal-burning power plant.The whole nation is annual because of attrition and attack causes loss that the boiler booster causes at least more than 10,000,000,000 yuan, and its remote effect that cause and loss are inestimable especially.
Traditional abrasionproof measure is to install abrasionproof steel watt on boiler tubing additional, watt yielding in operational process owing to steel, come off, deflection does not have good abrasionproof effect also influences thermo-efficiency.Anticorrosive measure adopts the aluminizing pipe technology usually, also can't play the ideal effect because infiltration layer is thin.Directly retube both uneconomical also not from dealing with problems in essence.Use common wear resistant anticorrosion paint to be difficult to obtain good result.
Summary of the invention
The object of the present invention is to provide and a kind ofly can make that the paint coatings bonding strength is higher, wear-corrosion resistance good, the Corrosion-resisting coating of anti-friction supercritical boiler and its preparation method of stable performance.
In order to achieve the above object, the technical solution used in the present invention is as follows:
A kind of super critical boiler wear resistant anticorrosion paint, it is characterized in that being made up of alumina in Nano level, nano level carbonization titanium, nano level silicon oxide and zirconium white, calcium aluminate, pyrophyllite in powder, metallic aluminium powder, calcium oxide, magnesium oxide, potassium oxide, sodium oxide and homemade high temperature resistant thick shape tackiness agent, its weight proportion is:

2Mix with 10～20% epoxy acrylates, its weight accounts for first component 28～35%.
The first component was through thorough mixing and ball milling 40 to 50 hours, the component B that adds weight again and be first component 28～35% stirs and transfers to pulp-like, form coating with 0.5～0.8MPa compressed air spraying to super critical boiler " four pipes " outside surface through processing of rust removing, thickness is 0.3～1mm, and forming certain intensity after solidifying in 24～48 hours can use.Along with boiler temperature this coating that raises will sinter the higher ceramic structure coating of bonding strength voluntarily into, and it is good to have a wear-corrosion resistance, characteristics such as stable performance.
The present invention compared with prior art has the following advantages: the nanometer wear resistant anticorrosion paint through said process preparation is easy to spraying application, the apparent exquisiteness of resulting coating, densification, do not ftracture, bubbling not.Behind high temperature sintering, has higher binding strength, good temperature tolerance and oxidation-resistance, good wear resistance and corrosion resistance nature.Also have the thermal conductivity higher than common inorganic coating.Adopt this coating also can realize for the position that can't protect originally.After using this coating, can improve 1～2 time between overhaul the work-ing life of " four pipes ".This coating can be widely used in high temperature Application Areass such as coal-fired plant boiler pipeline, chemical industry equipment, metallurgical industry.
