High-flame-retardant bubble heat insulation material

Abstract

The invention discloses a high-flame-retardant bubble heat insulation material. A flame-retardant polyethylene bubble layer is used as a middle basic layer, a first flame-retardant polyethylene layer is attached to the upper surface of the flame-retardant polyethylene bubble layer, a flame-retardant polyester polymer film layer is attached to the upper surface of the first flame-retardant polyethylene layer, a first aluminum film layer is attached to the upper surface of the flame-retardant polyester polymer film layer, a second flame-retardant polyethylene layer is attached to the lower surface of the flame-retardant polyethylene bubble layer, a flame-retardant woven cloth layer or a flame-retardant non-woven layer which is made of polyethylene or polypropylene and has the thickness of 10-100 microns is attached to the lower surface of the second flame-retardant polyethylene layer, and a second aluminum film layer is attached to the lower surface layer of the flame-retardant woven cloth layer or the flame-retardant polyethylene layer. The high-flame-retardant bubble heat insulation material has excellent performance, such as high flame retardation, high heat insulation, high corrosion resistance, high strength, shock absorption, and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a high-resistance gas-bubble heat-insulating material used in buildings. Background technique [0002] With the current global warming, in the environment of low-carbon economy, the state vigorously encourages and promotes energy conservation and emission reduction, and environmental protection and energy-saving buildings are an important part. At present, the building roof and wall heat insulation materials commonly used in the market are heat insulation materials formed by EPE foam or non-woven cloth and aluminum film single-layer composite. But it generally has the following disadvantages: first, EPE foam or non-woven fabric and other materials have poor shock absorption performance, and are easy to oxidize and corrode, and have a low service life. Generally, it will gradually lose its waterproof and heat preservation functions in two to three years. Secondly, this material has low ten...
