Title:
A fire prevention film and fire prevention glass
Document Type and Number:
Japanese Patent JP5993380
Kind Code:
B2
Abstract:
In this fireproof film (2), which results from a foamable insulating layer (21) being laminated to a resin film (23), an intermediate layer (22) containing inorganic microparticles is provided between the resin film (23) and the foamable insulating layer (21). Fireproof glass (3) results from the fireproof film (2), which is provided with the intermediate layer (22) containing inorganic microparticles between the resin film (23) and the foamable insulating layer (21), being provided onto glass (1) in a manner so that the foamable insulating layer (21) contacts the glass (1). The intermediate layer containing inorganic microparticles also functions as an ultraviolet ray shielding layer, prevents delamination of the resin film during high temperatures, and can increase the time of sustaining flame-shielding performance.
