Description
Technical field
The present invention relates to paint field more particularly to a kind of light energy absorption coating.
Background technology
Absorber coatings are very big on the technical and economic performance influence utilized, to improve the absorptivity of device, reducing cost, various countries
Scientific worker attaches great importance to studying, developing absorber coatings, is developed into a variety of coatings, and some has been used for producing, achieve
Good result.Electroplated coating is a kind of mature technology of absorbing material, is divided into black chrome coating or black nickel coating, the suction of black chrome coating
It is 6~13 that receipts, which are respectively 0.93-0.97 and 0.07-0.15, α/ε than α and transmitting ratio ε, is had excellent
Spectral selection.The thermal stability and high temperature resistant property of black chrome coating are also fine, are suitable for hot conditions, can be grown at 300 DEG C
Phase steady operation.In addition, black chrome coating also has preferable weatherability and corrosion resistance.But the electroplating black chromium work used now
Skill, current density is big (15~200A/dm2), and solution conductivity is poor, and when plating will produce a large amount of Joule heat, need
Cooling and vented exhaust could maintain normally to produce.In addition, black chromium is plated in non-copper piece, first copper pre-plating is needed, then plate light
Nickel, last black chromium plating, production cost are higher.Black nickel coating is mostly nickel-alloy coating, is formed with electroplate liquid composition and deposition
Condition changes.The electroplate liquid of black nickel is divided into two classes, i.e. zinc sulfate electroplate liquid and the electroplate liquid of salt containing molybdic acid.By first kind plating solution
The black nickel coating obtained, nickeliferous 40%~60%, it is about 20%~30% containing zinc.The absorptance α of black nickel coating is reachable
0.93~0.96, heat emission ratio ε be 0.08~0.15, α/ε close to 6~12, absorbent properties are preferable.It is black
Nickel coating is very thin, in order to improve the binding force and corrosion resistance of coating and matrix, frequently with inter coat (such as Ni, Cu, Cd)
Or the double-deck nickel coating.Since the thermal stability of black nickel coating, corrosion resistance are poor, it is usually applicable only to low-grade utility.With section
, also there are the technologies such as electrochemical surface conversion coatings, vacuum plating coating and pigment coating in the development of skill, and the coating type sun absorbs
Coating is a kind of optical surface of diffusion, is made of pigment and binder two parts.
