A kind of double-layer bubble type heat insulation film and its production equipment

Abstract

The invention relates to a double-layer bubble type heat insulation film. The heat insulation film sequentially comprises an aluminum foil bottom layer, a first bubble layer, an XPE foam cotton layer, a second bubble layer and an aluminum foil surface layer, wherein the aluminum foil bottom layer and the aluminum foil surface layer are formed by compounding aluminum foil and a PE film; the aluminum foil is positioned on the outer layer; the PE film is positioned on the inner layer. The double-layer bubble type heat insulation film is suitable for heat insulation of building ceilings and building external walls, is particularly suitable for simple house ceilings, can be directly paved on the top surface of the building, is high in heat insulation coefficient and good in heat insulation effect, and can provide normal working environment for operators; meanwhile, the two sides of the heat insulation film are made of aluminum foil, so that the heat insulation film is long in overall service life. The double-layer bubble type heat insulation film also has the characteristics of simple production process, high efficiency, low cost and the like, can be coiled and collected, and is small in size and simple in construction.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials and their production, in particular to thermal insulation materials for buildings, in particular to a double-layer air bubble type thermal insulation film and its production equipment. Background technique [0002] There are many types of thermal insulation materials on the market according to the applicable places, such as thermal insulation film for vehicles, thermal insulation film for glass windows, etc. Thermal insulation materials for buildings are mainly polystyrene board (EPS board), polyurethane foam material And perlite and other materials, and mainly made of hard plates, hanging on the building's exterior wall or top surface, the production cost of this kind of building insulation materials is high, the cycle is long, the product is heavy and bulky, and the construction inconvenient. At present, in the field of construction, there is no heat-insulating film profile...

Problems solved by technology

[0002] There are many types of thermal insulation materials on the market according to the applicable places, such as thermal insulation film for vehicles, thermal insulation film for glass windows, etc. Thermal insulation materials for buildings are mainly polystyrene board (EPS board), polyurethane foam material And perlite and other materials, and mainly made of hard plates, hanging on the building's exterior wall or top surface, the production cost of this kind of building insulation materials is high, the cycle is long, the product is heavy and bulky, and the construction inconvenient

At present, in the field of construction, there is no heat-insulating film profile that can be used directly. Ordinary heat-insulating films have low thermal insulation coefficient and poor heat-insulating effect, so they are not suitable as thermal insulation materials for buildings.
