Description
Technical field
The present invention relates to a kind of heat preserving and insulating material for road surface, in particular to a kind of resistance for alleviating urban heat land effect
Hot material.
Background technique
Urban heat land effect has become serious environmental problem, and harm not only shows that the summer weather that will lead to is cruel
In heat, it is also manifested by and endangers civic health, furniture atmosphere pollution, the natural calamity for causing some areas, leads to weather and object
Wait not normal, aggravation energy crisis.Bituminous pavement with its driving comfort the features such as good, low noise, short construction period, low cost at
A significant drawback for the principal mode of domestic and international road pavement, but asphalt concrete pavement is exactly the absorption to solar radiation
Ability is stronger.Newly-built pitch asphalt concrete pavement to the absorptivity of solar radiation energy up to 0.95, reuse in vehicle
Take turns under load action, wrap up building stones surface layer pitch be worn away after expose building stones, the reduction of road surface absorptivity can be made, but still reached
To 0.80-0.85.Due to solar radiation energy absorptivity with higher, a large amount of heat is caused to be accumulated in road structure again,
The temperature on road surface itself is not only increased, it is also highly exothermic to ambient enviroment.And excessively high pavement temperature is to cause bituminous pavement
One of the main reason for track disease and urban heat land effect.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of heat resistant material for alleviating urban heat land effect, using hot anti-
Penetrating reduces excessively high pavement temperature with thermal resistance technological means " initiatively ", or else increase or reduce plus highway construction cost on the basis of,
The operating temperature of pavement structure is reduced, track disease is controlled, while improving the thermophysical property that city is mated formation, can effectively delay
The urban heat land effect that solution is got worse provides more suitable living environment for city dweller, reduces since urban heat island is imitated
Bring refrigeration electricity consumption is answered, to play protection environment and energy saving effect.
The heat resistant material of alleviation urban heat land effect of the invention, raw material include following components by weight:30-40 parts poly-
Vinyl alcohol, 10-20 parts of polyoxyethylene polyoxypropylene pentaerythrite ethers, 10-20 parts of pure-acrylic emulsions, 2-6 parts of 3- glycidyl ether oxygens
Base propyl trimethoxy silicane, 4-9 part styrene-acrylic emulsion, 1-5 parts of rutile titanium dioxides, 5-10 parts of expanded perlites, 2-6 parts
Decylene glycol ester, 1-3 part hydroxyethyl cellulose, 5-10 parts of nano-hollow glass fibres, 2-6 parts of near-infrared reflection materials, 2-6 parts of second
Alkene-vinyl acetate co-polymer, 1-3 part dispersing agent;The near-infrared reflection material is made by following manner:
By Zn (NO3)2·6H2O and Ni ((NO3)2·9H2O is dissolved in deionized water, according to the ratio of molar ratio P/Zn=1.7
Phosphoric acid solution is added in example, water-bath 1-2 hour and stirs at a temperature of 50-60 DEG C, and then addition sodium carbonate liquor stirs evenly
And pH=7 is adjusted, presoma is obtained through precipitating, suction filtration, washing and drying, heat at being 600 DEG C -900 DEG C in temperature by presoma
Processing 4-6 hours;
Further, raw material includes following components by weight:35 parts of polyvinyl alcohol, 15 parts of polyoxyethylene polyoxypropylene seasons penta
Four alcohol ethers, 15 parts of pure-acrylic emulsions, 4 parts of 3- glycidyl ether oxypropyltrimethoxysilanes, 7 parts of styrene-acrylic emulsions, 3 parts of rutile
Type titanium dioxide, 7 parts of expanded perlites, 4 parts of decylene glycol esters, 2 parts of hydroxyethyl celluloses, 8 parts of nano-hollow glass fibres, 4 parts
Near-infrared reflection material, 4 parts of ethylene-vinyl acetate copolymers, 2 parts of dispersing agents;
Further;It water-bath 1.5 hours and is stirred at a temperature of 55 DEG C, sodium carbonate liquor is then added and stirs evenly and adjusts
PH=7 is saved, obtains presoma through precipitating, suction filtration, washing and drying, is heat-treated 5 hours at being 750 DEG C in temperature by presoma;
Further, the Zn (NO3)2·6H2O and Ni ((NO3)2·9H2In O, Zn:Ni=0.85:0.15;
Further, the dispersing agent is N, the mixture of N- ethylene two isostearic acid amide and grafted polybutadiene.
Beneficial effects of the present invention:The heat resistant material of alleviation urban heat land effect of the invention alleviates urban heat land effect
Heat resistant material, excessively high pavement temperature is reduced using heat reflection and thermal resistance technological means " initiatively ", or else increases or reduces
On the basis of adding highway construction cost, the operating temperature of pavement structure is reduced, controls track disease, while improving the hot object that city is mated formation
Characteristic is managed, the urban heat land effect got worse can be effectively alleviated, more suitable living environment is provided for city dweller,
It reduces due to urban heat land effect bring refrigeration electricity consumption, to play protection environment and energy saving effect.The present invention
Heat resistant material, not only can thermal resistance, moreover it is possible to by the anti-of the visible absorption of sunlight medium wavelength 400-750nm or so and reduction amount
Be shot out, can reflect back the black light of wavelength 750-2500nm is most, effective reflectivity up to 80-90%, from
And achieving the purpose that cooling, cooling extent fundamentally reduces the temperature of road surfaces up to 10-18 DEG C, can also reduce road body
Amount of stored heat, to reduce the Rutting damage of asphalt concrete pavement, prolonging service life of pavement improves traffic safety, while can
Improve the durability on road surface, rutting resistance.
