Abstract
The invention discloses cold roof reflective insulation paint which is characterized in that the paint is prepared by following raw materials comprising, by weight percentage, 40-50% of elastic pure acrylic polymer emulsion, 15-20% of light insulation fillers, 10-15% of nanometer semiconductor materials and 0.1-0.5% of cold pigments, wherein the cold pigments are BASF series cold pigments. The paint has high reflectivity on both light-colored coatings and deep-colored coatings, reaches high infrared reflectivity and high infrared shielding rate, has an infrared reflectivity up to 85% and has high insulation effect due to the high infrared reflectivity.
Description
Technical field
The invention belongs to building roof coating, relate in particular to a kind of cold roofing reflective heat-insulation paint and preparation method thereof.
Background technology
Economic sustained and rapid development brings becoming increasingly conspicuous of the energy, resource problem, protects environment, energy-saving and emission-reduction, makes rational use of resources, and the development low-carbon circular economy has become the great themes that attracts nation-wide attention.
American energy minister Zhu is subordinate to literary composition and in Xinmin Evening News, proposes " if white is painted on all roofs; road surface and automobile use light application; reflected solar radiation heat in a large number just, to use at the reduction Greenhouse effect, be equivalent to all automobiles in the world and stop the carbon emission of going and being reduced in 11 years.”
Cold roofing coating uses reflecting material to slow down the solar heat transmission, can cut down and load 20%.The characteristics of common cold roofing are light-colored surfaces, can be used on the flat bed face or low gradient roofing of commercial facility.But the household does not adopt this cold roofing form as yet, and is attractive in appearance than shade because they often tend on the roof, abrupt slope, to select for use, at present, attractive in appearance, dark color cold roofing product do not arranged as yet.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind ofly can effectively shield infrared light, low, the dark cold roofing reflective heat-insulation paint of heat transfer coefficient.The present invention also provides the preparation method of this kind coating.
The present invention seeks to realize like this: a kind of cold roofing reflective heat-insulation paint; It is characterized in that: it adopts and comprises that the following raw material of weight percentage makes: elasticity pure acrylic acid polymer emulsion 40～50%; Lightweight heat-proof filler 15～20%; Nano semiconductor material 10～15%, 0.1～0.15% cold pigment.
Adopt technique scheme; With lightweight heat-proof filler and nano semiconductor material is main raw material; Adopt cold pigment to carry out colour match and make this cold roofing reflective heat-insulation paint; Cold pigment has extraordinary sun inverse ratio and hemispherical emissivity, makes this coating not only on light coating, have higher reflectivity, and on dark coating, higher reflectivity is arranged also.Coating has reached high infrared reflection rate and shielding rate: up to 85%, coating high infrared reflection rate has high effect of heat insulation to ultrared reflectivity for it.Can be on roof pitch, metal coiled material, mix above earth base material, the polyurethane base material etc. and use, heat transfer coefficient is low, firmly durable, its excellent reflective insulation function can effectively reduce energy expenditure, and comfortable space is provided, the minimizing urban heat land effect.
As of the present invention preferred: it adopts and comprises that the following raw material of weight percentage makes: elasticity pure acrylic acid polymer emulsion 45%, lightweight heat-proof filler 18%, the cold pigment of nano semiconductor material 15%, 0.15%.
In technique scheme, also be added with auxiliary agent, its surplus is a deionized water; Said auxiliary agent comprises that weight percentage is 0.2～0.4% film coalescence aid, 0.5～0.7% dispersion agent, 0.2～0.3% skimmer, 0.1～0.2% pH value stabilization agent, 0.3～0.5% flow agent, 0.3% wetting agent, 0.5% mould inhibitor and thickening material of 0.2% etc.
In technique scheme: said nano semiconductor material adopts nanometer Bi doping SnO
2Semi-conductor powder and nanometer Po doping SnO
2The semi-conductor powder is by weight the mixing that is the proportioning of 1:1.
In technique scheme: said lightweight heat-proof filler is selected one or both in vitreous cenosphere, the hollow float bead for use, and the granularity of its vitreous cenosphere and hollow float bead is-300 orders.In technique scheme: said cold pigment is the serial cold pigment of BASF
.
The method method of cold roofing reflective heat-insulation paint of the present invention does; With nano semiconductor material described in the claim 3, water, lightweight heat-proof filler, elasticity pure acrylic acid polymer emulsion and auxiliary agent; Mix with the ultra-sonic oscillation method, shear and disperse, adjust viscosity to 70～80KU then; Promptly make the finished product whitewash, through cold pigment it is transferred to aim colour more at last.
The present invention has following beneficial effect:
1, this coating not only has higher reflectivity on light coating, and higher reflectivity is also arranged on dark coating.Coating has reached high infrared reflection rate and shielding rate: up to 85%, coating high infrared reflection rate has high effect of heat insulation to ultrared reflectivity for it.
2, coating of the present invention is water-borne coatings, more low-carbon (LC), more environmental protection, more energy-conservation.
3, coating use of the present invention is simple, difficulty of construction is low; Can directly be covered in all kinds of Roof systems; Can well combine as a whole with metal coiled material, asphalt felt, mixed earth base material, polyurethane base material etc.; Firmly durable, can prevent disadvantages such as ftractureing, come off, seep water, damage by worms and catch fire effectively.This is the usage period of prolong insulation thermal insulation layer greatly, reduces maintenance cost significantly.
4, coating of the present invention need not to reinstall new waterproof roll, does not produce solid waste, and is simple, prolongs the 5-10 roof life-span at least; Its excellent reflective insulation function can effectively reduce energy expenditure; Comfortable space is provided, reduces urban heat land effect, give full play to the more high-level efficiency (heat supply, ventilation, air-conditioning) of HVAC system; Avoid the peak energy consumption to produce, on average can practice thrift the 20-25% energy consumption.
5, the preparation method of coating is simple among the present invention.
