Description
Technical field
The present invention relates to solar paint field more particularly to a kind of solar energy absorbing paints.
Background technology
Solar energy absorbing coating is very big on the technical and economic performance influence of Solar use, to improve solar energy equipment
Rate reduces cost, and various countries solar energy scientific worker attaches great importance to studying, developing solar energy absorbing coating, is developed into more
Kind coating, some have been used for producing, and achieve good result.Electroplated coating is a kind of mature technology of solar absorptive material,
It is divided into black chrome coating or black nickel coating, the absorptance α and transmitting ratio ε of black chrome coating are respectively 0.93-0.97 and 0.
07-0.15, α/ε is 6~13, has excellent spectral selection.The thermal stability and high temperature resistance of black chrome coating
Can also very well, it, can long-term stable operation at 300 DEG C suitable for hot conditions.In addition, black chrome coating is also with preferable weather-proof
Property and corrosion resistance.But the electroplating black chromium technique used now, current density is big (15~200A/dm2), solution conductivity
Property it is poor, when plating, can generate a large amount of Joule heat, need cooling and vented exhaust that could maintain normally to produce.In addition, black chromium plating
In non-copper piece, first copper pre-plating, then bright nickel plating are needed, last black chromium plating, production cost is higher.Black nickel coating is mostly nickel
Alloy coat, composition change with electroplate liquid composition and sedimentary condition.The electroplate liquid of black nickel is divided into two classes, i.e. zinc sulfate is electroplated
Liquid and the electroplate liquid of salt containing molybdic acid.The black nickel coating obtained by first kind plating solution, nickeliferous 40%~60%, be about containing zinc
20%~30%.For the absorptance α of black nickel coating up to 0.93~0.96, heat emission is 0.08~0. than ε
For 15, α/ε close to 6~12, absorbent properties are preferable.Black nickel coating is very thin, in order to improve the binding force of coating and matrix
And corrosion resistance, frequently with inter coat (such as Ni, Cu, Cd) or double-deck nickel coating.Due to the thermal stability of black nickel coating,
Corrosion resistance is poor, is usually applicable only to low-temperature solar energy heat utilization.It is applied with the development of science and technology, also there is electrochemical surface conversion
The technologies such as material, vacuum plating coating and pigment coating, coating type sun absorber coatings are a kind of optical surfaces of diffusion, by pigment
It is formed with binding agent two parts.
