specific Embodiment approach 1

[0019] Embodiment 1: The rub-resistant flexible composite material is composed of 9 layers, which are flexible anti-aging layer, adhesive layer, barrier layer, adhesive layer, buffer layer, adhesive layer, load-bearing layer, adhesive layer from outside to inside. Tie layer and heat seal layer. The thickness of the anti-aging layer is 12-50um, and the surface density is 15-80g / m 2 ;The bonding layer density is 2~25g / m 2 ; The thickness of the barrier layer is 10-15um, and the surface density is 12-25g / m 2 ;The thickness of the buffer layer is 12~25um, and the surface density is 15~40g / m 2 ;The density of bearing layer is 60~130g / m 2 ; The surface density of the heat-sealing layer material is 15-40g / m 2 , each layer becomes an integrated and multi-functional material through the lamination composite preparation process.

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the material of the anti-aging layer is polyvinyl fluoride (PVF) film or polyvinylidene fluoride (PVDF) film. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Embodiment 3: This embodiment is different from Embodiment 1 in that the material of the barrier layer is PET film. Others are the same as in the first embodiment.

Abstract

The invention relates to the technical field of composite material manufacturing, in particular to a rubbing-resistant flexible composite material, wherein a flexible anti-aging layer, a bonding layer, a barrier layer, a bonding layer, a buffer layer, a bonding layer, a force bearing layer, a bonding layer and a heat sealing layer are sequentially arranged from outside to inside; the anti-aging layer and the barrier layer, the barrier layer and the buffer layer, the force bearing layer and the heat sealing layer are respectively bonded with a bonding layer, and the layers are compounded through laminating compounding into an integrated material; both the buffer layer and the heat sealing layer are made of thermoplastic polyurethane films, and are bonded with the force bearing layer and thebarrier layer by using a polyurethane adhesive, the thickness is 12-25 microns, certain barrier performance is achieved, meanwhile, rubbing of external force on the barrier layer and the anti-aging layer can be buffered through the self flexibility, a capsule material is protected, and penetrating pinholes do not appear after the capsule material is rubbed for 300 times.

Description

technical field [0001] The invention relates to the technical field of composite material manufacturing, in particular to a rub-resistant flexible composite material. Background technique [0002] The aerostat is a kind of aircraft that uses buoyant gas (hydrogen, helium, etc.) to achieve ascent. It can stay in the air and fly through power control. Due to the low cost of manufacturing and using aerostats, good invisibility, long time in the air, and load bearing Large and other characteristics, it has its unique performance advantages in military and civilian fields such as border patrol, urban security, air communication relay, sightseeing, cargo transportation, scientific investigation, etc., and has attracted great attention at home and abroad. [0003] Flexible composite materials are key materials for the manufacture and processing of aerostat buoyancy capsules. (1) The working environment of the aerostat has the characteristics of high and low temperature alternating...
