Thermal insulation sheet and method of manufacturing the same

Abstract

Disclosed herein is a thermal insulation sheet. The thermal insulation sheet comprises a bulk thermal insulation material 3, which is a void creator formed with bubbles therein, aluminum foil 10 attached to one side of the bulk thermal insulation material 3 by a direct heat or indirect heat (fused thereto by melting with fire at a temperature of 140 - 150 DEG C) and an oiled paper 7 attached to the other side of the bulk thermal insulation material by adhesives 2 such that the oiled paper can be used like a sticker. The insulation sheet has a total thickness of 3 mm. The insulation sheet can be directly attached to an existing building or a newly built building, so that the building can provide a wide inner space through the outside insulation construction using the insulation sheet. The aluminum foil provided in the insulation sheet prevents dewing and enhances insulation effect.

Description

technical field [0001] The present invention relates to a thermal insulation panel and a method of manufacturing the same, and more particularly to a thermal insulation panel including a bulk thermal insulation as a void creator with air bubbles formed therein and a method of manufacturing the same. ) material, aluminum foil bonded to one side of the bulk insulation material by direct heating or indirect heating (melted by fire at a temperature of 140-150°C), and oil paper bonded to the other side of the bulk insulation material by adhesive , so oil paper can be used as an adhesive. Background technique [0002] In conventional insulation panels, a silver-colored polyethylene film 4 as a material for insulating radiant heat is used as an insulation material, which is bonded with a foam polyethylene sponge or a foam polyethylene sponge as a void generator through an adhesive. The nonwoven fabrics 3 are joined. In addition, for glass fiber asbestos, perlite or the like used ...

AI Technical Summary

Problems solved by technology

In addition, for glass fiber asbestos, perlite or the like used as an inorganic heat insulating board, these materials are difficult to form a heat insulating board alone without an adhesive material or bonding material, and are useless on the surface of the heat insulating board. When other materials are firmly reinforced, it is difficult to guarantee its pressure resistance or impact resistance

Furthermore, although a design is proposed that provides foam insulation panels made of synthetic resins (Korean Utility Model Registration No. 0141039, Korean Patent Application No. 10-1998-0004097), it is not considered to be made of synthetic resins such as polystyrene foam, polyurethane foam, foamed vinyl, and the like), there is a problem that foam insulation panels are not suitable for applications that require pressure resistance, impact resistance, and surface strength. Applications

In addition, due to the weak fire resistance of synthetic resins, direct contact with fire will immediately cause the insulation board to be ignited and burn

Therefore, the proposed insulation panel still has the disadvantages of traditional foam insulation materials (such as the existing polystyrene foam or polyurethane foam), and it does not differ from traditional insulation panels in this respect.

In particular, as schematically shown the conventional insulation panel structure Figures 1 to 3 As shown, since the insulation panels proposed above also use materials that are not suitable for conventional insulation panels as insulation materials, they are the same as conventional bulk insulation materials such as polystyrene foam, polyurethane foam, glass wool and the like. , still has the disadvantage that the insulation board is easily ignited and burned by direct contact with fire

In addition, since the insulation board absorbs moisture in the air, its insulation efficiency is significantly reduced after 2 or 3 years, and condensation cannot be avoided, which also poses problems for traditional insulation systems

[0003] In addition, if figure 2 As shown, even if aluminum is laminated on the surface of the paper, when the insulation board is directly exposed to the fire, it will be ignited and burned immediately, or the position where the paper is bonded cannot be insulated against radiant heat
