Abstract
This invention provides a colour (brick red) solar energy selective absorption paint which is made up from light absorbent, adhesive, solvent and auxiliaries. Its colour is formed by proportioning multiple light absorbents having semi-conductor property and is mainly used to transform solar energy into heat energy. It not only has useful purpose, but also has decorative effect, and thus alters the monotonic situation of solar energy absorbing paint colour (black), especially is suitable for use as heat-absorption layer of solar energy water heater and solar energy greenhouse.
Description
The present invention is a kind of solar energy absorbing paint, be mainly used in sunlight is transformed into heat energy, be especially suitable for use as the heat absorbing coating of solar water heater and the heat absorbing coating that is used as solar heated green house, it comprises following feature: optical absorbing agent, binding agent, solvent and auxiliary agent.
Present solar energy heat absorbing coating all is black, and color is single.The Japanese Patent spy opens clear 58-57477 and discloses a kind of solar energy absorbing paint, in order to improve absorptive character, optical absorbing agent has used inorganic black pigment, the same with other solar energy absorbing paint, weak point be do not have ornamental, not attractive in appearance, can not constitute one to solar water heater and buildings in phase, more should not be as the heat absorbing coating of solar heated green house.And make defensive conventional colo(u)r coating, and have bolariously, but do not have the premium properties that absorbs sun power.
The objective of the invention is to overcome the deficiencies in the prior art part, provide a kind of bolarious, can be transformed into heat energy and the good solar energy absorbing paint of weather resistance to the solar energy highly effective rate.
Purpose of the present invention can reach by following measure: component of the present invention includes optical absorbing agent, binding agent, solvent and auxiliary agent.Bright-coloured brick-red for coating is had, and sun power had the excellent absorption performance, optical absorbing agent must possess special performances and requires so: at first, the primitive colour of main body optical absorbing agent is corresponding to be red.Secondly, they should have semiconductor property, so just, can give heat absorbing coating has the absorption selected to sun power spectrum characteristic, promptly to the wavelength below 2.5 microns, specific absorption (α) is very high, and to the wavelength more than 2.5 microns, emittance (ε) is very low, heat absorbing coating just can absorb sun power expeditiously so, and makes the radiation loss of itself very little.In addition, optical absorbing agent must have very little grain warp, and tiny particle can form very thin coating, and thin coating can reduce emittance (ε), reduces thermosteresis.
In view of the foregoing, optical absorbing agent of the present invention is at the ferric oxide (Fe below 0.2 micron by granularity
2O
3), selenium Cadmium Sulfide (CdS.CdSe), iron-manganese-copper oxide (FeMnCuOx) or cupric oxide (CuO) furnishing be brick-red, the variation of optical absorbing agent proportion of composing within the specific limits, the form and aspect that can align coating.Binding agent of the present invention adopts weather resistance good, and the mono-component polyurethane resin of being convenient to construct, solvent are dimethylbenzene, and auxiliary agent is a cobalt naphthenate solution.The weight percent of each component is:
Indian red 25-30%
Selenium Cadmium Sulfide 5-8%
Iron-manganese-copper oxide (or cupric oxide) 1-2%
Mono-component polyurethane resin 50-55%
Cobalt naphthenate solution 3-6%
Dimethylbenzene 6-8%
Manufacture method of the present invention: with various optical absorbing agents, mono-component polyurethane mixed with resin, stir, it is qualified fully to be ground to fineness through shredder, adds dimethylbenzene and cobalt naphthenate solution then, fully mixes well, and filters and packages promptly.
Optimum of the present invention also can use as protective paint as the heat absorbing coating that sun power is changed into heat energy.
The invention will be further described below in conjunction with embodiment.Heat absorbent is ferric oxide, selenium Cadmium Sulfide, cupric oxide, and its granularity is all between the 0.05-0.15 micron.The weight percent of each component of coating is:
Fe
2O
327.5%
CdS.CdSe 7.7%
CuO 1.1%
Mono-component polyurethane resin 52.7
Cobalt naphthenate solution 5%
Dimethylbenzene 6%
By above-mentioned manufacture method operation, just get the present invention.
In order to test various performance of the present invention, the spray painting that makes is being grown * galvanized iron sheet of wide * thick=60 * 60 * 1mm on, make the heat absorbing coating sample, after testing, the present invention compared with prior art has the following advantages:
1, color is bright-coloured brick-red, has both had usability, has again Ornamental.
2, record the absorptivity α of heat absorbing coating=0.92-0.95 with spectrophotometer, record the emissivity ε=0.3-0.4 of coating with the emissivity analyzer, this explanation the present invention can absorb the solar energy spectral selectivity, is that a kind of photo-thermal changes the very high good coating of efficient.
3, resistance to water of the present invention, chemical reagent resistance, resistance to ag(e)ing is all fine, and convenient construction.
