Description
Technical field
The present invention relates to technical field of coatings, be specially a kind of nanometer compound water-based heat insulation anticorrosion paint used for metal and preparation method thereof.
Background technology
Metallic substance will occupy critical role in field of materials with its good mechanical property and use characteristics; But always carve and also do not caused massive losses to human society in the metallic corrosion of carrying out, developing therefore efficiently that protective system protects it is the most simple and practical method.Facilities such as the storage equipment of making by metallic substance, petrochemical equipment, storage roof; Can be damaged by corrosion because of chemistry or the electrochemical action that receives surrounding medium for a long time on the one hand, can bring hidden danger because of the heat absorption in summer heats up on the other hand, along with the great attention of global economy development to resource, environment; Development set anticorrosive heat insulating function is in one; The Multifucntional coating of easy construction, aqueous, environmental protective meets the coating Development Trend, has a good application prospect.
Domestic cooling and insulating coating generally is divided into three kinds of isolation-types, reflection-type, radial pattern.The filler that is used for thermal insulating coating should possess low thermal conductivity (being high resistive properties) characteristic, and using maximum at present is hollow glass or ceramic fine bead.The high interstitital texture material of this type has thermal conductivity little (being generally 0.03-0.10W/ (mK)), plurality of advantages such as tap density is little, surface-area is little, wearing quality, weathering resistance, excellent corrosion resistance.
In the total quantity of radiant energy of the sun, ultraviolet region 0.2-0.4 μ m accounts for 5% of total energy; Visible region 0.4-0.72 μ m accounts for 45% of total energy; Near-infrared region 0.72-2.5 μ m accounts for 50% of total energy, and reflection type thermal insulation coating is mainly through improving the purpose that the sunshine reflectivity of visible light and near-infrared band is reached cooling.Semiconductor fills is a kind of novel doping filler; In theory; Suitably select parameters such as carrier density, carrier mobility and carrier impact frequency, can make doped semiconductor have lower emittance at infrared band, nano ATO (antimony-doped stannic oxide) is the mixtinite of transition metal oxide; Absorption and reflectivity to infrared light are very strong, are a kind of novel lagging materials.
The radiativity thermal insulating coating be beyond radiation mode go out the energy emission that absorbs and play heat-blocking action; The ir radiation powder mainly is the mixture and the carbide of MOX; Main radiation wave band is in the scope of 2.5～12 μ m; What use morely is transition metal or nonmetal oxide, like red stone, aluminum oxide, zirconium white etc.The super-refinement of ir radiation filler, nanometer are a kind of means that improve its emittance (emissivity); It also is the effective means that improves paint film compactness and then improve the coating antiseptic performance; But nanoparticle has, and particle diameter is little, specific surface area is big, surface energy is high, the insufficient characteristics of the serious coordination of surface atom; Directly add coating and be difficult to disperse, nano-powder is processed slurry, and to be scattered in the traditional coating the high performance nano composite dope of preparation be the hot subject of research at present.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art; A kind of nanometer compound water-based heat insulation anticorrosion paint used for metal is provided, and this coating had both satisfied the outer rot-resistant basic demand of metal, fully utilized obstruct, reflection, radiation heat insulation cool principle again; Integrate anticorrosive heat insulating; Characteristics such as have environment-protecting asepsis simultaneously, cost is low, and it is simple to construct.
Another purpose of the present invention is to provide a kind of preparation method of nanometer compound water-based heat insulation anticorrosion paint used for metal.
