Abstract
The invention relates to a method for increasing the heat reflection amount of the road surface, which comprises a step of adding far infrared ceramic powder into a road surface material. When the road surface is irradiated by sunshine to be heated, the far infrared ceramic powder can radiate infrared rays with the wavelength of 2 to 18mu m, and the absorption rate of the infrared rays with the wavelength of 2 to 18mu m in air is low, so the aim of radiating heat energy to the atmosphere in an infrared ray mode is fulfilled.
Description
Technical field
The present invention relates to a kind of method that increases heat reflection amount, particularly a kind of method that increases heat reflection amount of road surface.
Background technology
At present, adopt the heat-reflecting method in road surface to reduce environment temperature and pavement temperature.And the heat reflection on road surface will add hot air.
Summary of the invention
The purpose of this invention is to provide a kind of method that increases heat reflection amount of road surface.Utilize this method, the heat reflection on road surface can be transformed into long wave, make more heat reflect atmosphere to reduce the heat absorption of air.
For achieving the above object, the technical scheme that the present invention increases the method employing of heat reflection amount of road surface is: add far-infared ceramic powder in ground surface material.After the road surface was raise by the solar radiation temperature, far-infared ceramic powder was the infrared rays of 2～18 μ m with radiation wavelength.Wavelength is that the aerial absorptivity of the infrared rays of 2～18 μ m is low, so reach heat energy is given off atmospheric purpose in ultrared mode.
The method that the present invention increases heat reflection amount of road surface reaches the infrared spectral coverage of absorption of heat radiation being avoided air, the purpose that raises with the temperature that reduces air.
The invention has the beneficial effects as follows: method is simple, realizes easily, and is with low cost, improved operating efficiency.
Description of drawings
Fig. 1 is the infrared emanation spectrogram of the present invention's method of increasing heat reflection amount of road surface.
1. air short-wave band transmission spectrum curves among the figure, 2. air long-wave band transmission spectrum curve, 3. far-infared ceramic powder sends the infrared spectrum curve.
The specific embodiment
Add far-infared ceramic powder in ground surface material, the ratio of interpolation is 5%～15%.
The particle diameter of far-infared ceramic powder is that 100 orders are above, also can be nano far infrared ceramic powder.
In Fig. 1, illustrate that the principle of the invention is in far-infared ceramic powder sends between the peak region that the infrared spectrum curve is in air long-wave band transmission spectrum curve.Its energy absorption is few.
Claims (2)
1. a method that increases heat reflection amount of road surface comprises ground surface material, and far-infared ceramic powder is characterized in that: add far-infared ceramic powder in the ground surface material, the ratio of interpolation is 5%～15%.
