Description
Technical field
The present invention relates to pavement body.More particularly, relate to the pavement body that is used to suppress the pavement temperature rising.
Background technology
In recent years, the ground temperature that has produced the Urban areas in summer in a large number is higher than the Urban areas peripheral part heat island phenomenon of temperature on the ground.Its reason it is said since pavement bodies such as bituminous pavement institute accumulative heat on the road surface in nocturnal radiation, thereby make temperature not descend to be caused.If such heat island phenomenon continues, not only tellurian envrionment temperature rises, and also there is the problem that has difficulty in going to sleep night in the people.As the terms of settlement of heat island phenomenon,, can use the water-retentivity road surface of in porous matter pavement body, having filled the packing materials such as grout of water retention capacity excellence in order to suppress the temperature on the road surface.Utilize this water-retentivity road surface, if, can suppress the temperature rising (for example, the spy opens flat 10-46513 communique) on road surface because rainfall etc. in the road surface watering, utilize the vaporization heat that is trapped in the moisture in the packing material.
But, in above-mentioned water-retentivity road surface,, then can not fully obtain to suppress the effect that pavement temperature rises, thereby must in pavement body, supply with moisture if the intravital moisture of paving the way reduces.That is,, must manually sprinkle water in addition or sprinkle water with sprinkler when the few or complete anhydrous timesharing of the intravital moisture of paving the way.Therefore, existed for and obtained inhibition effect that temperature rises and bothersome problem.
As the technology that addresses the above problem, the known thermal insulation road surface that pavement body has been coated with the coating of heat reflectivity (infrared reflectivity) excellence.Utilize this thermal insulation road surface, the infrared rays in can the daylight on reflected illumination road surface, the intravital heat that can suppress to pave the way is accumulated.
But, in above-mentioned thermal insulation road surface, not only can reflected infrared, sometimes even also can reflect visible light.Therefore, in roads such as driveway, there is driver's the impaired problem of visibility.That is, because visible reflection of light for the driver, exists the road surface to produce the problem of spinning sensation.Particularly when fine day, this tendency is obvious.If use dark-coloured heat reflectivity coating, though can improve visibility, because the heat reflectivity of dark-coloured coating is poor, thereby the inhibition effect that pavement temperature rises is low.
As the thermal insulation road surface that addresses the above problem, known coating is by the technology (for example, the spy opens the 2004-218301 communique) of the heat reflection coatings that reflectivity constitutes more than or equal to 13% tinting pigment at sunshine.The tinting pigment of black such as the tinting pigment that this heat reflection coatings with heavy colours such as phthalocyanine greens is, complex metal oxides system makes up in a large number and is mixed.By at this heat reflectivity coating of coating that paves, can suppress the temperature rising on road surface.
But, in above-mentioned heat reflection coatings, owing to must use the tinting pigment of any kind of, thereby exist being mixed of heat reflection coatings to become complicated, the problem that takes a lot of trouble during use.
Summary of the invention
The objective of the invention is to address the above problem.
The present invention relates to lay the pavement body that is fixed on the roadbed or on the roadbed.This pavement body has the parent of paving the way, is coated on the coating on the surface of the parent of paving the way.Coating is black pigment, white pigment and the vehicles (vehicle) of Han You perylene system at least.In the present invention, so-called " parent of paving the way " is meant " matrix " that constitutes pavement body.
Wherein, in the present invention, the black pigment of so-called “ perylene system ", be meant Ju You perylene skeleton, for black or extremely near the pigment of the color of black.The infrared reflection rate height of the black pigment of You Yu perylene system, ultrared specific absorption is low, and the temperature that therefore can effectively suppress the road surface rises.As the black pigment of Ju Ti De perylene system, can use for example Paliogen Schwarz S-0084 (trade(brand)name, BASF AG makes).In the black pigment of ， Zai perylene system, also the black pigment of the inorganic system that comprises composite oxides that can infrared reflectivity is high mixes use in addition.As the black pigment of concrete inorganic system, for example can use AG235 (trade(brand)name, river village chemical company makes), 42-703A (trade(brand)name, eastern tank material technology company makes).In addition, in the present invention, so-called " white pigment " is meant to have white or extremely near the pigment of the color of white.As concrete white pigment, can use titanium oxide, zinc oxide, aluminum oxide etc.
In addition, in coating of the present invention,, can suitably mix vehicles in order in coating, to disperse various pigment efficiently.This vehicles can be used acrylic resin, MMA (methyl methacrylate) resin, Resins, epoxy, urethane resin, fluoro-resin, silicone resin, Vinylite, vibrin, acrylic emulsions resin, decolouring asphalt emulsion etc. according to the difference of construction site etc.
Wherein, as driveway usefulness, preferably use the high MMA resin of quick solidifying and intensity.In addition, when using, preferably use the acrylic emulsions resin in public places such as park, squares.This is because the acrylic emulsions resin is constructed easily, and cost is reduced.In addition, as walkway usefulness, preferably use urethane resin.Urethane resin can make the pavement body surface have elasticity, reduces the burden to pedestrian foot.
According to the present invention, though make the simplification that is mixed of the coating that is coated on the parent of paving the way, the pavement body with this coating can suppress the temperature rising on road surface significantly.In addition, because the black pigment and the white pigment of perylene system mixed use,, the infrared rays that incides the road surface can be reflected efficiently by both interactions.That is, the black pigment of the Zhi Yong perylene system infrared rays that can not reflect is fully also reflected by white pigment.Therefore, the temperature that can suppress the road surface effectively rises.In addition, according to the present invention, sharp with the black pigment of perylene system and the effect of white pigment, visible reflection of light is inhibited, and can not damage driver's visibility.
In addition, in the present invention, in the scope that being mixed of coating do not become complicated, can in coating, mix other pigment with various tones.For example, also can mix the high pigment of infrared reflectivity.By mixing these pigment, can obtain presenting various tones, and the temperature rising suppresses the high pavement body of effect.As such pigment, for example comprise pigment dyestuffs such as azo system, quinoline a word used for translation ketone system, alizarin Xi, perylene system (redness), anthraquinone system, isoindoline system, benzimidazolone system, phthalocyanine system, halogenated phthalocyanines system, indanthrone system, pinkish red system, two piperazine systems, with the composite oxides of Fe, Cr, Co, Cu etc. mineral dye as principal constituent.In addition, can also mix filler pigment, bright pigment and photoluminescent pigment.As filler pigment, comprise lime carbonate, vertical spar powder etc.As bright pigment, comprise pigments, mica, aluminium powder form etc.As photoluminescent pigment, comprise phosphorescent pigment, high-visibility pigment.
The containing ratio that mixes black pigment, white pigment and other pigment of other pigment Shi ， perylene system in coating of the present invention is preferably 3～15 weight %.This be because, if Zong the pigment containing ratio is lower than 3 weight %, the temperature on road surface rise to suppress effect and significantly reduces, otherwise, even containing ratio greater than 15 weight %, the temperature on the road surface inhibition effect that rises can not further improve.
In coating of the present invention, preferably use titanium oxide as white pigment.Because the light reflective excellence of the infra-red range of titanium oxide, the temperature that therefore can positively suppress the road surface rises.In titanium oxide, preferred especially Titanium Dioxide (Rutile) Top grade.Titanium Dioxide (Rutile) Top grade is not only in the light reflective excellence of infra-red range, and opacifying property is also excellent.In addition, the anti-chalkification of Titanium Dioxide (Rutile) Top grade is also excellent.That is, Titanium Dioxide (Rutile) Top grade can make to film has photostabilization, and it is Powdered to be difficult to make the surface of filming to form.
In addition, Titanium Dioxide (Rutile) Top grade is usually because of the difference characteristic difference of its kind.Therefore, in the present invention, select Titanium Dioxide (Rutile) Top grade with desirable characteristic.For example, for common Titanium Dioxide (Rutile) Top grade, the infrared penetration rate of wavelength 1.4～3.0 μ m is about 36%.But, in the present invention, use the infrared penetration rate to be lower than 36% Titanium Dioxide (Rutile) Top grade (that is, the infrared reflection rate is higher than common Titanium Dioxide (Rutile) Top grade).For example, in the present invention, use JR-1000 (trade(brand)name, テ イ カ company makes).The infrared penetration rate of wavelength 1.4～3.0 μ m of JR-1000 is 3.0%, so preferred.But be not limited to JR-1000, can use any Titanium Dioxide (Rutile) Top grade that has identical or better characteristic with it.Like this, by the kind of suitable selection Titanium Dioxide (Rutile) Top grade, can form desirable pavement body.Described infrared penetration rate can adopt for example Fourier transform infrared light-dividing device mensuration.By this device, can measure the ultrared penetration coefficient of each wavelength.
In addition, in coating of the present invention, can contain hollow minute particle.Wherein, so-called " hollow minute particle " is meant very tiny granulous material, and there is the independently material of hollow space in portion within it.By in coating, adding hollow minute particle, can form the pavement body of excellent in heat insulating performance.The hollow minute particle excellent in heat insulating performance of inorganic system particularly, heat reflectivity and weather resistance are also excellent, so preferably.As the hollow minute particle of inorganic system, comprise the hollow minute particle of silica-based pottery, the hollow minute particle of silica alumina system etc.
In addition, hollow minute particle can be used the hollow minute particle of various particle diameter.For example, can use the hollow minute particle of median size less than 45 μ m.Such particle diameter can force down face concavo-convex of coating composition, therefore can not damage the heat reflectivity of pavement body.
In addition, the containing ratio of hollow minute particle preferably contains 5～15 weight % with respect to coating.This be because, if the containing ratio of hollow minute particle is lower than 5 weight %, effect of heat insulation is low, otherwise, even containing ratio surpasses 15 weight %, can further not improve effect of heat insulation yet, and the intensity of coating is reduced.
In addition, as hollow minute particle, preferred pyrex.Pyrex can improve the weather resistance and the withstand load of pavement body.Therefore, if use pyrex, can form the load that can fully bear oversize vehicle, ballistic pavement body as hollow minute particle.As pyrex, comprise for example Fuji Balloon S-4 5 (trade(brand)name, シ リ シ ア chemical company of Fuji makes).It can form 300kg pressurization destructive rate and (hollow minute particle be applied 300kg/cm
2Hydrostaticpressure and the percentage by volume of destructive particle) less than 20 volume % (mean value is 15 volume %), the pavement body of withstand load excellence.
In addition, by hollow minute particle is made spherical shape, can further improve the heat reflectivity of filming.
In addition, in the present invention, in the scope that being mixed of coating do not become complicated, can in coating, suitably be mixed for suppressing the isolating material (for example dispersion agent, separation inhibitor etc.) of pigment, hollow minute particle.
Similarly, also can blending surface adjust agent, lubricant, softening agent, defoamer, sanitas, frostproofer, solidifying agent, pigment branch and spread agent, emulsifying agent, siccative, UV light absorber, mould inhibitor, antiseptic-germicide etc.
Similarly, before coating composition on the parent of paving the way, also can in coating, mix silica sand, manufactured aggregate etc. in advance as anti-slip material.
Similarly, in order to adjust the viscosity of coating, can in coating, suitably add organic solvent equal solvent or water.
In the present invention, can coating be applied on the parent of paving the way by the whole bag of tricks.
For example, at first, clean the surface of the parent of paving the way, remove dust, moisture.Then, form the 1st layer at this surface coated coating.Then, when the 1st layer coating was also uncured, an amount of anti-slip material that scatters was fixed on the 1st layer anti-slip material on the 1st layer.Behind the 1st layer the paint solidification, the identical coating of coating forms the 2nd layer on it.
In addition, in other method, can remove after dust, the moisture on the pave the way surface of parent of cleaning, coating has been pre-mixed the coating of anti-slip material.
In addition, in other method, at first, the coating that coating has been pre-mixed anti-slip material forms the 1st layer.Then, at the 1st layer coating of surperficial repeated multiple times and the 1st layer of identical coating.In the method, preferably behind the paint solidification of the layer (lower floor) that is coated with before, coating is one deck down.
Coating is applied on the parent of paving the way also can be undertaken, also can use hairbrush, brush, rake etc. to carry out by the spraying of having used machines such as spray gun.
In addition, the glue spread of coating (in the situation of scattering anti-slip material, not comprising the dispersion volume of this anti-slip material) is preferably 0.2～1.5kg/m
2This be because, if be lower than 0.2kg/m
2, the temperature that can not give full play to the road surface suppresses effect, otherwise, even be higher than 1.5kg/m
2, the temperature that can not further improve the road surface rises and suppresses effect.Most preferred glue spread is 0.3～1.0kg/m
2
According to the present invention, being mixed of coating that is coated on the parent of paving the way very oversimplified.
In addition, the temperature that can suppress the road surface effectively rises.
By in coating, containing hollow minute particle, can form the pavement body of excellent in heat insulating performance.
And then, by selecting the material of hollow minute particle, can form the pavement body of weather resistance and withstand load excellence.

As shown in table 2, the temperature measuring value of embodiment all demonstrates the value of the temperature measuring value that is lower than comparative example.Hence one can see that, and the temperature of embodiment rises and suppresses the temperature rising inhibition effect excellence of effect than comparative example.Confirm in addition,, also can bring into play the temperature inhibition effect that rises fully even with simplifications that be mixed of coating.
If the result is carried out detailed research, for example, the temperature measuring value that does not contain the embodiment 1 of hollow minute particle is hanged down 16.9 ℃ than comparative example 1, hangs down 12.9 ℃ than comparative example 2, hangs down 3.3 ℃ than comparative example 3, hangs down 13.5 ℃ than comparative example 4.In addition, embodiment 5 demonstrates minimum temperature measuring value in an embodiment.Embodiment 5 hangs down 21.5 ℃ than comparative example 1, hangs down 17.5 ℃ than comparative example 2, hangs down 7.9 ℃ than comparative example 3, hangs down 18.1 ℃ than comparative example 4.Hence one can see that, if as present embodiment, use has mixed the coating of the black pigment of perylene system, compares with the employed situation of the coating that is mixed with common iron oxide black pigment, combined oxidation system black pigment of having used so far, can obtain bigger temperature and rise and suppress effect.
In addition, the temperature measuring value of embodiment 7 is hanged down 15.2 ℃ than the temperature measuring value of comparative example 4, confirms thus, even using under the situation of acrylic emulsions as vehicles, also has sufficient temperature rising and suppresses effect.
In addition, the temperature measuring value of embodiment 4 is hanged down 2.1 ℃ than the temperature measuring value of embodiment 2.In addition, the temperature measuring value of embodiment 5 is hanged down 3.4 ℃ than the temperature measuring value of embodiment 2.Therefore, (in embodiment 4 and embodiment 5, their amount of being mixed always is 4.0, in embodiment 2 though the amount of being mixed always of the black pigment of embodiment 4 and embodiment 5 and white pigment is lacked than embodiment 2, their amount of being mixed always is 5.0), suppress effect but demonstrate the efficient temperature rising.This shows that if as embodiment 4 and embodiment 5, mix hollow minute particle in coating, the temperature on road surface rises and suppresses effect raising (not containing hollow minute particle among the embodiment 2).Therefore, as the coating on the surface that is coated on the parent of paving the way, be preferably the coating that “ mixes black pigment, white pigment, vehicles and the hollow minute particle of perylene system ".In addition, the temperature measuring value of embodiment 5 is hanged down 1.3 ℃ than the temperature measuring value of embodiment 4.Therefore show,, can expect that better temperature rising suppresses effect if as embodiment 5, use pyrex as hollow minute particle.Therefore, as the coating on the surface that is coated on the parent of paving the way, “ coating that the hollow minute particle of black pigment, white pigment, vehicles and the pyrex of perylene system is mixed more preferably ".
In addition, the temperature measuring value of embodiment 2 is hanged down 1.2 ℃ than the temperature measuring value of embodiment 1, and the temperature measuring value of embodiment 5 is hanged down 1.7 ℃ than the temperature measuring value of embodiment 3.Hence one can see that, under the situation of visually identical bright degree (brightness), if use the high Titanium Dioxide (Rutile) Top grade (for example white pigment 1) of infrared reflectivity as white pigment, compare as the situation of white pigment with having used common Titanium Dioxide (Rutile) Top grade (for example white pigment 2), can bring into play better temperature rising and suppress effect.
