High-efficiency and heat-insulation color steel compound plate

Abstract

The invention discloses a high-efficiency and heat-insulation color steel compound plate and belongs to the field of construction materials. The high-efficiency and heat-insulation color steel compound plate uses a color steel plate or a color aluminium plate as a base plate and adopts the technical scheme that a non-woven fabric layer, an aluminium foil layer and a PET laminating layer are bonded to the outer surface of the base plate in sequence; embossed patterns are arranged on the PET laminating layer in the outermost part; a PE coating and a PE film layer are arranged between the non-woven fabric layer and the aluminium foil layer. The product is obvious in heat-insulation effect due to low absorbance, sound-proof, fire-resistant and corrosion-proof at the same time, simple and reasonable in structure, thin and light in weight, easy to transport, mount and dismount, and long in service life, does not reflect light, causes no light pollution, and achieves the purposes of energy conservation and environmental friendliness at the same time.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a color-steel composite board with high-efficiency heat insulation. Background technique [0002] As the wall panels, roof panels and construction site walls of temporary buildings, color steel plates are usually used, but color steel plates are easy to absorb sunlight, and the heat on the surface of color steel plates continues to accumulate under sunlight. The temperature of the inner layer reaches more than 50 degrees. The inner layer of the color steel plate is like a radiator. The normal living of human beings, material storage, and equipment safety have all had a great impact. There may be great safety hazards such as explosions, which require cooling and cause a great waste of energy. In the prior art, in order to insulate heat, two pieces of color steel plates are used, and the middle of the two color steel plates is thickened with a layer of core material. ...

Problems solved by technology

[0002] As the wall panels, roof panels and construction site walls of temporary buildings, color steel plates are usually used, but color steel plates are easy to absorb sunlight, and the heat on the surface of color steel plates continues to accumulate under sunlight. The temperature of the inner layer reaches more than 50 degrees. The inner layer of the color steel plate is like a radiator. The normal living of human beings, material storage, and equipment safety have all had a great impact. There may be great safety hazards such as explosions, which require cooling and cause a great waste of energy.

In the prior art, in order to insulate heat, two pieces of color steel plates are used, and the middle of the two color steel plates is thickened with a layer of core material. The core material is usually: plastic core material, honeycomb core material or polyethylene core material. The color steel plate The surface of the surface still absorbs infrared rays and accumulates heat, and the heat insulation effect is not good, and the double-layer color steel plate has many consumables, heavy weight and volume, is not easy to transport, difficult to install, and poor in firmness
