Abstract

The invention relates to a special sound insulation and heat insulation glass fiber composite material for aviation, and a preparation method thereof, and belongs to the technical field of glass fibermaterials. The composite material comprises, by mass, 78-90% of glass fiber wool and 10-22% of composite resin, and the composite resin comprises phenolic resin, organic fluororesin and a silicone resin. The glass fiber cotton in the composite material is regularly uniformly distributed, has a small longitudinal and transverse distribution difference, an obvious hierarchical structure and small pores, can effectively reduce acoustic conduction and heat transfer caused by radiation, convection and conduction, and has good sound insulation and heat insulation effects; and the preparation methodhas the advantages of simplicity, low cost, and suitableness for enlarged production.

Description

technical field [0001] The invention belongs to the technical field of glass fiber materials, and in particular relates to a special sound-insulating and heat-insulating glass fiber composite material for aviation and a preparation method thereof. Background technique [0002] Glass fiber wool belongs to a category of glass fiber and is a kind of man-made inorganic fiber. Natural ores such as quartz sand, limestone, dolomite are used as main raw materials, and some chemical raw materials such as soda ash and borax are used to melt into glass. In the molten state, it is blown into flocculent fine fibers by external force, and the fibers are three-dimensionally intersected and intertwined with each other, presenting many small gaps, which can be regarded as pores. Therefore, glass wool can be regarded as a porous material with good heat insulation and sound absorption properties. The reason why glass wool can absorb sound is not because of the rough surface, but because it h...
