Problems solved by technology

[0002] As an excellent flame retardant, fireproof and thermal insulation material, carbon fiber cotton can still maintain looseness, softness, good elasticity and stability at high temperatures, and has good high temperature shrinkage, heat insulation, shock resistance and sound absorption performance. The surface is made of good materials, and the commonly used thermal insulation veneer has a good thermal insulation effect due to the insulation cotton and the surface-coated material, but there are often formaldehyde and benzene harmful small molecule volatile substances in the rubber material, and the overall flame retardancy The performance is difficult to meet the relevant requirements, and cannot be directly used in passenger cars

Embodiment 1

[0021] A flame-retardant carbon fiber cotton veneer, the flame-retardant carbon fiber cotton veneer has a two-layer structure, one of which is a flame-retardant carbon fiber cotton layer 1, and the other layer is a hot-melt adhesive layer, and the hot-melt adhesive layer is coated On the flame-retardant carbon fiber cotton layer 1, the hot melt adhesive layer includes a fiber transition layer 3 and a surface coating 2, the fiber transition layer 3 is formed by mixing hot melt adhesive and fiber cotton, and the surface coating 2 Inside is a single hot melt adhesive. The thickness of the hot-melt adhesive layer is 0.2mm, and the thickness of the fiber transition layer 3 is 0.1-0.12mm, which can prevent the bonding force between the adhesive layer and the fiber cotton from being insufficient, resulting in the high-temperature attachment of the carbon fiber veneer. When there is a problem of fiber cotton falling off, at the same time prevent the amount of glue on the surface coati...

Embodiment 2

[0027] A flame-retardant carbon fiber cotton veneer, the flame-retardant carbon fiber cotton veneer has a two-layer structure, one of which is a flame-retardant carbon fiber cotton layer 1, and the other layer is a hot-melt adhesive layer, and the hot-melt adhesive layer is coated On the flame-retardant carbon fiber cotton layer 1, the hot melt adhesive layer includes a fiber transition layer 3 and a surface coating 2, the fiber transition layer 3 is formed by mixing hot melt adhesive and fiber cotton, and the surface coating 2 Inside is a single hot melt adhesive. The total thickness of the hot-melt adhesive layer is 0.3mm, and the thickness of the fiber transition layer 3 is 0.1-0.2mm, which can prevent the insufficient bonding force between the adhesive layer and the fiber cotton, resulting in the high temperature attachment of the carbon fiber veneer. When there is a problem of fiber cotton falling off, at the same time prevent the amount of glue on the surface coating 2 f...

Embodiment 3

[0033] A flame-retardant carbon fiber cotton veneer, the flame-retardant carbon fiber cotton veneer has a two-layer structure, one of which is a flame-retardant carbon fiber cotton layer 1, and the other layer is a hot-melt adhesive layer, and the hot-melt adhesive layer is coated On the flame-retardant carbon fiber cotton layer 1, the hot melt adhesive layer includes a fiber transition layer 3 and a surface coating 2, the fiber transition layer 3 is formed by mixing hot melt adhesive and fiber cotton, and the surface coating 2 Inside is a single hot melt adhesive. The thickness of the hot-melt adhesive layer is 0.5mm, and the thickness of the fiber transition layer 3 is 0.2-0.3mm, which can prevent the insufficient bonding force between the adhesive layer and the fiber cotton, resulting in the carbon fiber veneer being pasted at high temperature. When there is a problem of fiber cotton falling off, at the same time prevent the amount of glue on the surface coating 2 from bein...
