Air isolating aluminum foil

Abstract

The invention discloses air isolating aluminum foil which comprises an aluminum foil layer and an air isolating layer. Single-side glossy aluminum foil is adopted as the aluminum foil layer, the upper surface of the aluminum foil layer is a glossy surface, and the lower surface is a non-glassy surface; the air isolating layer is fixedly adhered to the position under the aluminum foil layer and divided into an upper air isolating layer body and a lower air isolating layer body; a plastic film layer is arranged under the lower air isolating layer body, an aluminum laminated film layer is arranged on the lower surface of the plastic film layer; the thickness of the aluminum foil layer is 0.04-0.08 mm; a heat preseravation layer is arranged between the upper air isolating layer body and the lower air isolating layer body; the upper air isolating layer body, the heat preservation layer and the lower air isolating layer body are all fixedly adhered through a waterproof air isolating adhesive. According to the air isolating aluminum foil, a multi-layer composite structure is adopted in the structural design, and on one hand, the air isolating layer and the plastic film layer both have the excellent air tightness and moisture resistance, air transmission can be isolated, and the temperature stability can be guaranteed; on the other hand, the heat preservation performance and the air isolating function of the product can be promoted through the heat preservation layer; the cost is effectively reduced, and environmental protection and energy conversation are achieved.

Description

technical field [0001] The invention relates to an aluminum foil, in particular to a gas-insulating aluminum foil. Background technique [0002] Aluminum foil is a soft metal film. It not only has the advantages of waterproof and moisture-proof, air and heat insulation, light shading, abrasion resistance, non-toxic and tasteless, but also because of its natural luster and easy processability, it is used in industrial production and household daily necessities. and other fields. Due to its non-toxic and odorless environmental performance, aluminum foil is widely used as interior decoration and thermal insulation materials in houses, vehicles or ships. However, in some places where heat insulation, air insulation, waterproof, moisture-proof and other factors are particularly high due to the use environment, it is necessary to mix and press aluminum foil and other materials, because the aluminum foil of the composite structure can use the respective characteristics of the comp...
