Abstract
The present invention relates to a kind of preparation technique of the water heater heat collecting pipe surface covering of efficient heat-collecting, innovative point is：It is to be prepared from the following raw materials：Resin, absorbent, auxiliary agent and solvent；It improves the low disadvantage of existing solar energy absorbing paint formula coating solar-energy availability, can not only be the thermal energy that is converted into of solar energy highly effective rate, and the weatherability of coating, guarantor's light colour retention are excellent.Solar energy absorbing paint formula of the invention, is mainly used for solar energy to be transformed into thermal energy, especially suitable for solar water heater, greenhouse etc..
Description
Technical field
The present invention relates to technical field of solar water heaters more particularly to a kind of water heater heat collecting pipe surfaces of efficient heat-collecting
The preparation technique of coating.
Background technique
Solar energy absorbing coating is very big on the influence of the technical and economic performance of Solar use, for the suction for improving solar energy equipment
Light rate reduces cost, and various countries solar energy scientific worker attaches great importance to research, exploitation solar energy absorbing coating, is developed into
A variety of coatings, some have been used for producing, and achieve good result.Electroplated coating is a kind of mature skill of solar absorptive material
Art is divided into black chrome coating or black nickel coating, and 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 resistant property of black chrome coating are also fine, fit
It, can long-term stable operation at 300 DEG C for hot conditions.In addition, black chrome coating also has preferable weatherability and corrosion resistance.But
It is the electroplating black chromium technique used now, current density is big (15~200A/dm2), and solution conductivity is poor, and when plating can generate
A large amount of Joule heat needs cooling and vented exhaust that could maintain normally to produce.In addition, black chromium is plated in non-copper piece, elder generation is needed
Copper pre-plating, then bright nickel plating, last black chromium plating, production cost are higher.Black nickel coating is mostly nickel-alloy coating, is formed with electricity
Bath element and sedimentary condition variation.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.
The black nickel coating obtained by first kind plating solution, nickeliferous 40%~60%, it is about 20%~30% containing zinc.The absorptance of black nickel coating
α is up to 0.93~0.96, and heat emission ratio ε is 0.08~0.15, α/ε close to 6~12, and absorbent properties are preferable.Black nickel coating is very
It is 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-temperature solar energy heat utilization.With the hair of science and technology
, also there are the technologies such as electrochemical surface conversion coatings formula, vacuum plating coating and formulation for coating material type coating, formulation for coating material type is too in exhibition
Positive absorber coatings are a kind of optical surfaces of diffusion, are made of pigment and binder two parts.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparing for the water heater heat collecting pipe surface covering of efficient heat-collecting
Technique.
In order to solve the above technical problems, the technical scheme is that：A kind of water heater heat collecting pipe surface of efficient heat-collecting
The preparation technique of coating, it is made of the raw material of resin, absorbent, auxiliary agent and solvent；The absorbent is by carbon black tune
It is made into black, the auxiliary agent includes dispersing agent, levelling agent, plasticizer, wherein the dispersing agent is polymer electrolyte dispersion
Agent, the levelling agent are silicon oil liquid, and the plasticizer is BBP(Butyl Benzyl Phthalate.
The advantage of the invention is that：
The present invention improves the low disadvantage of existing solar energy absorbing paint coating solar-energy availability, can not only be solar energy highly effective rate
Be converted into thermal energy, and the weatherability of coating, to protect light colour retention excellent.Solar energy absorbing paint formula of the invention, mainly
For solar energy to be transformed into thermal energy, especially suitable for solar water heater, greenhouse etc..
Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
A kind of preparation technique of the water heater heat collecting pipe surface covering of efficient heat-collecting, it be by resin, absorbent, auxiliary agent and
The raw material of solvent is made；The absorbent is that black is deployed by carbon black, and the auxiliary agent includes dispersing agent, levelling agent, increasing
Mould agent, wherein the dispersing agent is high-molecular type dispersing agent, and the levelling agent is silicon oil liquid, and the plasticizer is neighbour
Phthalic acid butyl benzyl.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
It is merely illustrated the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also has
Various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention
It is defined by the appending claims and its equivalent thereof.
