Abstract
The present invention relates to heat-absorbing paint of a sealed shining type solar water heater, which is made of heat-absorbing materials and adhesives, wherein the heat-absorbing materials are prepared from carbon black, manganese dioxide, lithopone, titanium white, lead powder, calcium chloride and zinc powder according to a certain proportion by weight, and the adhesives are sodium silicate. Compared with the prior art, the paint has high heat-absorbing efficiency which is up to 70% or more, the service life of the paint is longer than 10 years, and the cost of the paint is low. The present invention provides a wide prospect for the development of sealed shining type solar water heaters.
Description
The present invention relates to a kind of passive solarenergy water heater's heat-absorbing paint, belonging to the resorber is the solar energy collector technical field of coatings of feature.
Among the existing passive solarenergy water heater, generally adopting lustreless paint is heat-absorbing paint, this lustreless paint mainly contains carbon black, titanium dioxide etc., and containing the tackiness agent composition, the characteristics of this coating are that its cost is low, but its specific absorption to sunlight is not high, cause the thermo-efficiency power of water-heater to be 30-40%, and this coating is short work-ing life, only be 3-4, above-mentioned deficiency has limited greatly passive solarenergy water heater's with low cost, popular to people deeply development.
The objective of the invention is to provide a kind of passive solarenergy water heater's heat-absorbing paint at above-mentioned deficiency of the prior art, it has the specific absorption senior middle school to sunlight, the characteristics of long service life, reach practical purpose with low cost again, thereby provide wide prospect for passive solarenergy water heater's development.
Technical essential of the present invention is: suitable weight ratio scope and the optimum weight ratio that each component of heat absorption material Tu is provided.
The present invention is made up of heat-sink material and tackiness agent, wherein, described heat-sink material contains carbon black, titanium dioxide etc., or rather, described heat-sink material is to contain carbon black, Manganse Dioxide, lithopone, lead powder, calcium chloride, the composition of refined powder component, and, the prescription of this composition is pressed carbon black: titanium dioxide: MnZn barium white: titanium white: powder lead powder: calcium chloride: zinc powder=1: (0.010-0.014): (0.010-0.015): (0.035-0.040): (0.010-0.015): (0.045-0.053): weight ratio (0.015-0.025), its optimum weight ratio is 1: 0.012: 0.012: 0.037: 0.012: 0.049: 0.020, even the heat-sink material that adopts identical each component to form, as exceed weight ratio scope provided by the present invention, then can reduce heat absorption rate significantly, in addition, with the heat absorption rate of optimum weight ratio gained heat-sink material for the highest.Each component of above-mentioned heat-sink material is solid-state Powdered or particulate state, and carbon black, Manganse Dioxide, lithopone, titanium dioxide are the heat absorbents to sunlight, and lead powder can absorb energetic ion especially, and zinc powder plays the surface anticorrosion effect.Among the present invention, described tackiness agent adopts solid-state water glass to get final product.With carbon black, Manganse Dioxide, lithopone, titanium dioxide, lead powder, calcium chloride, zinc powder, be mixed into heat-sink material by weight ratio scope provided by the present invention, adding water glass is mixed, the add-on of general tackiness agent is 3-4 a times of heat-sink material weight, has promptly formed passive solarenergy water heater's heat-absorbing paint.During actual the use, add entry as one feels fit and make thinner, stir, be prepared into the coating of user mode, it is painted on the thermal-arrest plate and thermal-collecting tube of solar water heater, dry in the shade or fire-cure with flame, until forming velvet-like dry hair side, be passive solarenergy water heater's heat absorbing coating.
Compare prior art, the present invention has following advantage:
1, to the specific absorption height of sunlight, water-heater thermo-efficiency reaches more than 70%, has started passive solarenergy water heater's four seasons available precedent.
2, long service life can reach more than 10 years.
3, with low cost.
4, high temperature resistant and low temperature, 130 ℃ of high temperature and low temperature do not ftracture for subzero 20 ℃.
Below the present invention is further elaborated by three embodiment.
Embodiment one component carbon black Manganse Dioxide lithopone titanium dioxide lead powder calcium chloride zinc powder sodium silicate water weight g 100 1.1 1.1 3.6 1.1 4.6 1.7 400 surpluses
