Description
Technical field
The present invention relates to solar water pipe paint field, more particularly to a kind of solar water pipe absorbing coating.
Background technology
The technical and economic performance influence that solar water pipe absorber coatings utilize solar water pipe is very big, to improve solar energy
The rate of pipe device, reduce cost, and various countries solar water pipe scientific worker is to studying, developing solar water pipe absorber coatings
Attach great importance to, be developed into a variety of coatings, some has been used for producing, and achieves good result.Electroplated coating is that solar water pipe is inhaled
A kind of mature technology of material is received, is divided into black chrome coating or black nickel coating, ε points of the absorptance α and transmitting ratio of black chrome coating
Not Wei 0.93-0.97 and 0.07-0.15, α/ε be 6~13, there is excellent spectral selection.Black chrome coating
Heat endurance and high temperature resistant property it is also fine, can long-term stable operations at 300 DEG C suitable for hot conditions.In addition, black chromium
Coating also has preferable weatherability and corrosion resistance.But the electroplating black chromium technique used now, current density it is big (15~
200A/dm2), solution conductivity is poor, and when plating can produce substantial amounts of Joule heat, it is necessary to which cooling down could maintain with vented exhaust
Normal production.In addition, black chromium is plated in non-copper piece, it is necessary to first copper pre-plating, then bright nickel plating, last black chromium plating, production cost compared with
It is high.Black nickel coating is mostly nickel-alloy coating, it is formed changes with electroplate liquid composition and sedimentary condition.The electroplate liquid of black nickel point
For two classes, i.e. zinc sulfate electroplate liquid and the electroplate liquid of salt containing molybdic acid.The black nickel coating obtained by first kind plating solution, nickeliferous 40%
~60%, it is about 20%~30% containing zinc.The absorptance α of black nickel coating is up to 0.93~0.96, heat emission ratio
ε for 0.08~0.15, α/ε close to 6~12, its absorbent properties is preferable.Black nickel coating is very thin, is applied to improve
The combination power and corrosion resistance of layer and matrix, frequently with inter coat (such as Ni, Cu, Cd) or double-deck nickel coating.Due to black nickel
Heat endurance, the corrosion resistance of coating are poor, are usually applicable only to low-temperature solar energy water pipe heat utilization.With the development of science and technology,
There are the technologies such as electrochemical surface conversion coatings, vacuum plating coating and pigment coating, coating type sun absorber coatings are a kind of
The optical surface of diffusion, is made of pigment and binding agent two parts.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of solar water pipe absorbing coating.
In order to solve the above technical problems, the technical scheme is that：A kind of solar water pipe absorbing coating, its innovative point
It is：It is made of following raw material：Resin, absorbent, extender pigment, auxiliary agent and solvent；The absorbent is by carbon
It is black, enamel is black, chrome oxide green is deployed into black, the extender pigment includes blanc fixe and talcum powder；The auxiliary agent
Including dispersant, levelling agent, plasticizer, coupling agent, anti-settling agent, wherein, the dispersant is inorganic molecule type dispersant, institute
The levelling agent stated is ethyl silicon oil liquid, and the plasticizer is dibutyl phthalate, and the coupling agent is silane coupled
Agent, the anti-settling agent are the N monomethyl pyrrolidones of modified polyurea；The solvent includes acetone, ethyl acetate and to two
Toluene；
The resin, absorbent, extender pigment, the parts by weight of auxiliary agent and each specific raw material of solvent are as follows：Concentration is 45%
- 55% acrylic resin is 28-35 parts, carbon black is 1.0-2.4 parts, enamel it is black be 4-9 parts, chrome oxide green be
1.1-1.8 parts, the talcum powder of 400-600 mesh be 15-18 parts, the blanc fixe of 400-600 mesh is 8-11 parts, changes
The N monomethyl pyrrolidones of property polyureas is 0.6 part, silane coupling agent is 0.2-0.5 parts, inorganic molecule type dispersant is
1.5-1.9 parts, concentration be 0.5%-1.5% silicone oil be 0.1 part, dibutyl phthalate is 2-5 parts, acetone 6-8
Part, ethyl acetate are 8-10 parts, paraxylene is 24.7-26.7 parts.
The advantage of the invention is that：
1）It improves the shortcomings that existing solar water pipe absorbing coating coating solar-energy water pipe availability is low, can not only be solar energy
Water pipe is efficient to be converted into thermal energy, and the weatherability of coating, guarantor's light colour retention are excellent.The solar water pipe of the present invention
Absorbing coating, is mainly used for solar water pipe to be transformed into thermal energy, especially suitable for solar water pipe water heater, greenhouse
Deng.
