Description

High-temperature-resistant and flame-retardant automotive carpet

Technical Field

The utility model relates to an automotive carpet, especially a high temperature resistant, fire-retardant automotive carpet.

Background

The automotive carpet belongs to a part of automotive interior, and has the functions of absorbing water, preventing dirt, insulating sound, improving foot treading feeling and protecting an automotive body carpet. Patent numbers: CN201220480612.1 discloses an automotive carpet, which comprises a three-layer composite structure, the upper layer is a carpet, the middle layer is a fixed layer, and the bottom layer is a composite layer. According to the specification of the scheme, the composite layer is formed by alternately compounding PE and PA, the fixing layer is made of PE materials, and the carpet is a tufted carpet. The materials in the scheme are inflammable and non-high temperature resistant materials, so that when the cigarette ends of smokers fall off carelessly in a car, the car carpet is extremely easy to be burnt by the cigarette ends and even ignited, and safety accidents are caused. Therefore, an automotive carpet with high temperature resistance and flame retardant function is needed.

SUMMERY OF THE UTILITY MODEL

In view of the above insufficiency, the utility model aims to provide a high temperature resistant, fire-retardant automotive carpet makes automotive carpet still possess high temperature resistant, fire-retardant characteristic under the condition that possesses basic function.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a high temperature resistant, fire-retardant automotive carpet, includes the blanket body, the blanket body includes the PET stratum basale, the upper surface on PET stratum basale sets up hot melt PE rete, and hot melt PE rete upper surface sets up inhales the sound composite bed, the upper surface of inhaling the sound composite bed sets up first ceramic fiber precoat, the fire-retardant PVC coating of upper surface spraying on ceramic fiber precoat, the upper surface on first ceramic fiber precoat is still evenly planted and is established the carbon fiber.

In this scheme, the PET stratum basale has extremely strong wearability, then makes through the mode of hot melt and inhale sound composite bed and firmly combine with the PET stratum basale. The structure ensures that the automobile carpet keeps the excellent properties of water absorption, sound insulation and protection of the traditional automobile carpet. Meanwhile, a first ceramic fiber fabric layer with high temperature resistance and flame retardance is arranged on the upper surface of the attraction composite layer, so that high-temperature objects are prevented from being burnt or ignited after falling on the automobile carpet. The high-temperature-resistant carbon fibers are uniformly planted on the surface of the first ceramic fiber fabric layer, so that the feet of a passenger can feel soft after being placed on an automobile carpet, and meanwhile, a high-temperature object can be overhead after the high-temperature object drops on the automobile carpet, and the high-temperature object is prevented from directly conducting heat to the lower side. It should be noted that, in order to improve the appearance of the scheme, a flame retardant PVC coating is further sprayed on the surface of the first ceramic fiber fabric layer.

Preferably, the upper end of the carbon fiber is bent and rolled.

The upper end of the carbon fiber is bent, so that the touch feeling of the automobile carpet can be further improved, and thorns and hard feeling caused by the inorganic fiber are reduced.

Preferably, inhale the sound composite bed and include the cotton layer of PET and with the cotton layer complex foaming EVA layer in PET.

The PET cotton layer has the effect of making an uproar, making an uproar that gives sound insulation, and the foaming EVA layer then has sound absorbing effect, and the two combines, can effectively promote the sound insulation effect of car pad.

Preferably, a second ceramic fiber fabric layer is arranged between the PET cotton layer and the foaming EVA layer, and the upper surface of the PET cotton layer is wavy.

The upper surface on the PET cotton layer is set into a wavy shape, so that the contact area between the second ceramic fiber fabric layer and the PET cotton layer and between the second ceramic fiber fabric layer and the foaming EVA layer can be effectively increased, and the flame retardant effect of the second ceramic fiber fabric layer can be furthest exerted.

Preferably, the difference from wave crest to wave crest of the upper surface of the PET cotton layer is not less than 1/3 of the thickness of the sound absorption composite layer.

In the scheme, the ceramic fiber fabric with flame-retardant and high-temperature-resistant performances and the automobile carpet made of the carbon fiber and the traditional high polymer resin material are organically combined, so that the high-temperature-resistant and flame-retardant characteristics which are not possessed by the traditional automobile carpet are endowed.
