The effectively insulating color steel
Technical field
The invention belongs to building material field, especially relate to a kind of color steel with effectively insulating.
Background technology
Color steel is typically used as wall board for building, roofing slab, also be used as the enclosure wall in building site, but color steel easily absorbs sunshine, color steel surface heat constantly accumulates under the sunshine, the temperature on color steel surface is up to more than 60 degree during sunshine in summer, the temperature of its internal layer also reaches degree more than 50, the internal layer of color steel is just as a radiator, under such high temperature, in habitat, the factory building workshop, what the temperature in the silo grain depot was inevitable is raising, and gives human normal the inhabitation, material is deposited, the safety of equipment has all caused very big influence, might produce great potential safety hazards such as blast, need cooling, cause the significant wastage of the energy simultaneously again.In the prior art, a kind of heat insulation color steel commonly used is to paste extruded sheet or foaming plate at the endonexine of color steel, and the surface of this color steel still absorbs infrared rays and accumulates heat; A kind of thermal insulation color steel, its color steel are two-layer, are separated with cavity between the described two-layer color steel, and the color steel surface is provided with topping, and it is many that this kind color steel consumptive material is many, weight doubles, and its surface still absorbs infrared rays and accumulates heat; Another kind of heat insulation PE color steel all is coated with zinc coat, chemical conversion layer, thermal control polyester layer, heat insulation PE coating in the both sides of cold-reduced sheet, this color steel production process is many.
Summary of the invention
In order to overcome the above-mentioned deficiency of background technology, the purpose of this invention is to provide a kind of effectively insulating color steel.
Effectively insulating color steel of the present invention, it is substrate with the color steel, its technical scheme is: sticking the carrying out of the external surface of substrate an aluminium foil layer is arranged.
As improvement of the present invention, be provided with the multiple rete of PET at aluminium foil layer.
The present invention is at the sticking aluminium foil layer of carrying out of color steel external surface, light such as sunshine can be reflected, in visible wavelength 0.38-0.765m scope, its reflectivity can reach 70-80%, in infrared ray wavelength 0.76-505m scope, reflectivity can reach 75-100%, its heat-insulating efficiency height, also non-scald on hand of the surface temperature of color steel during sunshine in summer, therefore, improve color steel building interior environmental degree of comfort significantly, provide strong support to energy-conservation and environmental protection; The PET that arranges is multiple, and rete has anticorrosion, anti-aging function, prolongs the application life of aluminium foil layer and color steel substrate, further saves use cost; The low cost of manufacture of this product, simple in structure and be easy to the transportation, dismounting.
Description of drawings
Fig. 1 is the structural representation of effectively insulating color steel of the present invention.
1-substrate, 2-aluminium foil layer, the multiple rete of 3-PET among the figure.
Below in conjunction with the drawings and the specific embodiments the present invention is described in further detail.
The specific embodiment
As shown in Figure 1, effectively insulating color steel of the present invention, it is substrate with the color steel, its technical scheme is: sticking the carrying out of the external surface of substrate 1 aluminium foil layer 2 is arranged.Aluminium foil layer can reflect light such as sunshine, in visible wavelength 0.38-0.765M scope, its reflectivity can reach 70-80%, in infrared ray wavelength 0.76-505M scope, reflectivity can reach 75-100%, its heat-insulating efficiency height, also non-scald on hand of the surface temperature of color steel during sunshine in summer, therefore, improve color steel building interior environmental degree of comfort significantly, provide strong support to energy-conservation and environmental protection.
As improvement of the present invention, be provided with the multiple rete 3 of PET at aluminium foil layer, PET is multiple, and rete has anticorrosion, anti-aging function, prolongs the application life of aluminium foil layer and color steel substrate, further saves use cost.
