Abstract

The invention discloses a rail transit vehicle interior roof decoration composite material and a preparation method thereof. The composite material is formed by sequentially compounding a lower panel,a glue film, a honeycomb core, a glue film and an upper panel from bottom to top, wherein the upper panel and the lower panel are formed by curing a phenol formaldehyde resin-impregnated fiber cloth,the glue film is a modified phenol formaldehyde resin glue film with an area density of 100-400 g / m<2>, and the composite phenol formaldehyde foam comprises a phenol formaldehyde resin, polyimide microspheres, modified basalt fiber, perlite, calcium carbonate microspheres, a fly ash gel, graphene oxide, azodicarbonamide and a surfactant. According to the present invention, the composite materialadopts the structure of the phenol formaldehyde resin-impregnated fiber cloth-composite phenol formaldehyde foam-phenol formaldehyde resin-impregnated fiber cloth, has high structural strength, further has advantages of simple structure, easy molding, good sound insulation effect, good thermal insulation effect, good compression resistance and the like, and can improve the safety of rail transit vehicle interior roof decoration.

Description

technical field [0001] The invention relates to the field of rail transit vehicle materials, in particular to a rail transit vehicle interior roof decoration composite material and a preparation method thereof. Background technique [0002] The application of new materials is the most important and effective way to realize the lightweight of high-speed maglev vehicles, and it is one of the most important key technologies for the development of high-speed rail trains. For materials, in addition to requiring light weight, they must also have higher strength, modulus, toughness, wear resistance, fatigue resistance, aging resistance, flame retardancy and other properties. Sandwich structure composite materials have large bending stiffness / weight ratio, high bending strength / weight ratio, and good sound absorption and heat insulation properties, and are widely used in the interior roof decoration materials of rail trains. [0003] Sandwich structure composite materials are gener...
