Abstract

The utility model discloses a layer structure of an anti-fouling carpet, which comprises a TPO surface layer and a PUR foaming layer, wherein the TPO surface layer is arranged on the PUR foaming layer; the top layer anti-soil performance of the carpet of this structure is good, and is easy clean, satisfies the net car of appointment and requires high easy abluent requirement to carpet top layer anti-soil, and simultaneously, the TPO top layer adds the layer structure on PUR foaming layer, has promoted the NVH performance of product, can block most noise that comes from vehicle chassis, plays the function of making an uproar that falls that gives sound insulation.

Description

Layer structure of anti-pollution carpet

Technical Field

The utility model relates to an automotive carpet technical field, in particular to layer structure of anti-soil carpet.

Background

With the rapid development of the automobile market and the continuous improvement of the living standard of people, the requirements of people on the speed feeling, the driving feeling, the comfortable feeling, the safety feeling and the like of automobiles are gradually improved.

The automobile generates a large noise in the driving process, such as noise of mechanical components such as an engine, friction sound of tires and the ground, collision and friction sound generated by the automobile breaking through an air curtain, sound transmitted into the automobile from an external environment, and internal noise generated by vibration of parts such as an interior trim of a cab. The long-time noise is easy to have great influence on the health of human bodies, so that the noise in the vehicle needs to be eliminated.

At present, the causes of the generation of noise in the vehicle mainly include: the automobile bottom plate is poor in sound insulation material, and road noise is easily transmitted to a cab; poor assembly, loosening of the suspension system, or aging failure of the fittings, which cannot effectively reduce vibration; the whole car sheet metal process and the thickness of the used iron sheet are not enough, and the like. Generally, a way to reduce noise in a vehicle is to lay a carpet of the vehicle inside the vehicle. However, the performance of the car carpet is poor, and the noise in the car cannot be reduced to a great extent.

Along with the popularization and development of the net car, the surface anti-pollution performance of the automobile carpet needs to be effectively improved and is easy to clean, so that the requirement that the net car has high anti-pollution requirement on the surface of the carpet and is easy to clean is met.

Disclosure of Invention

The utility model aims at solving the defects in the background art and providing a carpet layer structure with good anti-pollution performance on the surface layer of an automobile carpet and convenient cleaning.

The utility model provides a layer structure of anti-soil carpet, includes TPO top layer and PUR foaming layer, and the TPO top layer sets up on the PUR foaming layer.

Preferably, the TPO skin comprises a PP material and an EPDM material and a layer of non-woven fabric.

The process and the manufacture of the utility model are as follows:

the TPO surface layer comprises a PP material and an EPDM material which are mixed and then attached with a layer of non-woven fabric, and the TPO surface layer has good surface anti-fouling performance, easy cleaning and good sound insulation performance.

PUR foamed layer: and further plays a role in sound absorption and sound insulation.

The TPO surface layer is placed on heating equipment for heating, then the TPO surface layer is placed into a plastic suction mould for plastic suction forming, a semi-finished product after the plastic suction forming is placed into a foaming mould, one side of a non-woven fabric faces to the surface to be foamed, then a certain amount of foaming material is poured, mould closing and foaming are carried out, a PUR foaming layer is added behind the non-woven fabric, and then the punching mould is used for punching holes and punching edges.

The utility model has the advantages that:

the top layer anti-soil performance of the carpet of this structure is good, and is easy clean, satisfies the net car of appointment and requires high easy abluent requirement to carpet top layer anti-soil, and simultaneously, the TPO top layer adds the layer structure on PUR foaming layer, has promoted the NVH performance of product, can block most noise that comes from vehicle chassis, plays the function of making an uproar that falls that gives sound insulation.

Drawings

Fig. 1 is a schematic view of the layer structure of the present invention.

Detailed Description

Referring to fig. 1, a layer structure of an anti-fouling carpet includes a TPO surface layer 2 and a PUR foam layer 1, wherein the TPO surface layer 2 is disposed on the PUR foam layer 1.

Preferably, the TPO skin 2 comprises a PP material and an EPDM material and a layer of non-woven fabric.

The process and the manufacture of the utility model are as follows:

TPO top layer 2 includes PP material and EPDM material after mixing, attaches the one deck non-woven fabrics, and the surface anti-soil performance is good, and easy cleanness, sound insulation performance are good.

PUR foam layer 1: and further plays a role in sound absorption and sound insulation.

The TPO surface layer 2 is placed on heating equipment for heating, then is placed into a plastic suction mould for plastic suction forming, a semi-finished product after the plastic suction forming is placed into a foaming mould, one side of a non-woven fabric faces to the surface to be foamed, then a certain amount of foaming material is poured, mould closing foaming is carried out, a PUR foaming layer 1 is added behind the non-woven fabric, and then a punching die is used for punching and trimming.

Claims

1. A layer structure of anti-soil carpet which characterized in that: including TPO top layer (2) and PUR foaming layer (1), TPO top layer (2) set up on PUR foaming layer (1), TPO top layer (2) upper surface be provided with the one deck non-woven fabrics.
