Preferably, the thickness of the reinforced self-adhesive gas-barrier film in the composite aluminum foil glass fiber is less than 0.8 cm.
The utility model discloses beneficial effect:
1. aluminium possesses outstanding gas barrier property, but the shortcoming is the poor easy brittle fracture of toughness, the utility model discloses a coating process is compound on the aluminium foil with the PE polyethylene that the elongation percentage of fracture is high or the tensile PET polyester of high temperature resistant for compound aluminium foil layer has combined the advantage of two kinds of materials, and gas barrier property is good, and toughness is strong, the reinforcing is supported, high temperature resistant.
2. The glass fiber mesh cloth used by the inner enhancement layer enhances the strength and flexibility of the air barrier film, can absorb the force in the length direction and the width direction at the same time, is not easy to be stepped and rubbed to damage, and plays a role in reducing the temperature difference.
3. The asphalt of the self-adhesive layer not only has the performance of gas isolation, but also is in contact fit with the composite aluminum foil through meshes of the glass fiber gridding cloth, so that the glass fiber gridding cloth is equivalently tightly fixed between the composite aluminum foil and the asphalt, and the effect of supporting and connecting is achieved.
4. The utility model discloses the fine interior reinforcing self-adhesion gas barrier membrane of compound aluminium foil glass has formed a similar vacuum structure, not only separates the gas, but also can reach good heat preservation effect to a certain extent moreover.
