Abstract

The utility model relates to a noise-reduction sound-insulation carpet for a light-duty vehicle. The carpet is formed by one-time composite binding of a bed material layer, an intermediate layer and a coat material layer, and covers the sheet metal of the vehicle floor, providing combined effect of noise-reduction and sound-insulation, elegant appearance and peaceful and comfortable interior vehicle environment.

Description

Lilliput car noise reduction sound insulation carpet

Technical field

The utility model relates to the cover panel on the automotive floor panel panel beating, specifically lilliput car noise reduction sound insulation carpet.

Background technology

Along with automobile is more and more universal, people are also increasingly high to the traveling comfort requirement of automobile, reduce car noise and also paid close attention to by people widely.

But, the domestic existing carpet that automobile reduces noise that is used for, majority is individual layer or two-layer compound, its material uses nonwoven fabrics, PVC or regeneration felt more.Because the characteristic of these materials and structure not only causes carpet moulding typing weak effect, can't reach good effect aspect the noise reduction sound insulation; Nor possess good protection against the tide, heat-proof quality, do not meet environmental demands.

Summary of the invention

The purpose of the utility model is a kind of novel carpet of design, makes it have good noise reduction soundproof effect and compliance with environmental protection requirements.

Summary of the invention

The utility model is to realize design goal like this.

In car, be coated with on the panel beating of floor with interlayer 2 and precoat 1 disposable composite adhered together, noise is had the initial bed 3 that stronger absorptive character material is processed;

On initial bed 3, be coated with interlayer 2 and precoat 1 disposable composite adhered together, to have the interlayer 2 that the material of styling and sound insulation and noise reduction effect is preferably processed;

On interlayer 2, be coated with interlayer 2 and initial bed 3 disposable composite adhered together, the precoat of processing with economic, attractive in appearance, generous material 1.

The utility model so the noise that not only below is transmitted absorbs, is accomplished the first step of noise reduction because initial bed 3 is to process noise is had stronger absorptive character material, can also with the tight applying of panel beating;

Because interlayer 2 is to process to have preferably the material of styling and sound insulation and noise reduction effect, so the noise that is not absorbed fully by initial bed 3 is played tight insulating effect;

Because precoat 1 is processed with economic, attractive in appearance, generous material, so give people with attractive in appearance, generous comfort.

Because it is all nontoxic to form the various materials of the utility model, do not have bad smell, and flame retardance is good, so compliance with environmental protection requirements can built the quiet riding environment of safety and comfort for the client.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, a non-limiting examples is explained.

Make initial bed 3 with the PE expanded material.Make interlayer 2 with the EVA material; With poly-ester fibres and add low-melting fiber mixing needle punched non-woven fabrics and make precoat 1;

When making the utility model, put initial bed 3, interlayer 2 and precoat 1 successively, through mould high pressure disposable thermal synthesis type, like this, the utility model is had good stability again, can not produce the distortion bounce-back.Be laid in the utility model of making on the panel beating of automotive floor panel, get final product.

The utility model not only has good noise reduction sound insulation value, and toughness, impact resistance, anti tear and protection against the tide, heat-proof quality are superior, are on-deformable good environment-friendly products.
