Document Type and Number:
WIPO Patent Application WO/2023/221355
Kind Code:
A1
Abstract:
Disclosed is an insulating thin film for a large aircraft, comprising: a first thin film base material layer, a second thin film base material layer and a flame-retardant fusion adhesive layer and a fiber mesh layer which are located between the first thin film base material layer and the second thin film base material layer. The flame-retardant fusion adhesive layer is composed of 70-90 parts of modified melamine formaldehyde resin and 10-30 parts of halogen-free phosphorus-containing flame retardant; the modified melamine formaldehyde resin is composed of the following components in parts by weight: 100 parts of melamine, 150-250 parts of a formaldehyde solution, 2-6 parts of polyethylene glycol, 8-20 parts of ethylene glycol, 10-30 parts of urea, 10-15 parts of paraformaldehyde, 3-8 parts of hexahydrophthalic anhydride and 2-4 parts of carbodiimide. The flame-retardant fusion adhesive layer in the insulating thin film for a large aircraft of the present invention improves the stability of the toughness of an adhesive with increase of the temperature while improving the toughness of the adhesive, thereby improving the weather resistance of the flame-retardant fusion adhesive layer.
