Problems solved by technology

The sunlight absorption rate (solar radiation absorption coefficient) of the aluminum foil insulation board is extremely low (0.07), has excellent thermal insulation performance, and can reflect more than 93% of radiant heat, and is widely used in building roofs and external walls for thermal insulation , but the existing plastic foam or plastic foam layer is highly flammable, which makes the application of insulation boards and building insulation have greater safety hazards

Embodiment Construction

[0011] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0012] As shown in the figure, the present invention includes a steam retarder layer 14, a light flame-retardant glass fiber layer 16 disposed above the steam retarder layer and an aluminum foil adhesive layer 12 disposed above the light flame-retardant glass fiber layer, The aluminum foil adhesive layer includes an outer layer of aluminum foil film 13 and an inner layer of polyester film 15 compounded by lamination. The aluminum foil adhesive layer is provided with a plurality of ventilation holes 60 to facilitate the flow of air from the inner layer of the heat insulation book .

[0013] The upper surface of the light flame-retardant glass fiber layer is bonded to the polyester film through a high-temperature-resistant...

Abstract

An inflaming-retarding reflective insulation plate comprises a steam retarder layer, a light inflaming-retarding glass fiber layer arranged on the steam retarder layer, and an aluminum foil bonding layer arranged on the light inflaming-retarding glass fiber layer. The aluminum foil bonding layer comprises an aluminum foil film on the outer layer and a polyester film on the inner layer, the aluminum foil film and the polyester film are compounded in a laminated mode, and the aluminum foil bonding layer is provided with a plurality of ventilating through holes. Due to the fact that the light inflaming-retarding glass fiber layer is adopted, the insulation plate has the character of inflaming retarding. In addition, compared with the prior art, the thickness of the light inflaming-retarding glass fiber layer is greatly reduced, and therefore the defect that an existing insulation plate is inflammable is overcome, and higher applicability is achieved.

Description

technical field [0001] The invention relates to a heat insulation board, in particular to a flame-retardant reflective heat insulation board. Background technique [0002] Aluminum foil heat insulation board is made of aluminum foil veneer and polystyrene board and other plastic foam boards laminated by hot melt adhesive. The aluminum foil coil has the functions of heat insulation, waterproof and moisture resistance. The sunlight absorption rate (solar radiation absorption coefficient) of the aluminum foil heat insulation board is extremely low (0.07), has excellent heat insulation performance, and can reflect more than 93% of radiant heat, and is widely used in building roofs and external walls for heat insulation , but the existing plastic foam or plastic foam layer is highly flammable, which makes the application of the heat insulation board and the heat insulation of buildings have greater safety hazards. Contents of the invention [0003] The technical problem to be ...
