Abstract

The invention relates to a method for producing a car carpet with an ethylene propylene diene monomer layer. The method includes the following steps that a composite carpet surface carpet is laid on a surface carpet feeding table of a forming machine and is fixed, wherein the carpet is provided with three layers of raw materials, the upper layer is the fleece surface carpet, the middle layer is EPDM, and the lower layer is non-woven fabric; the fixed composite carpet surface carpet is fed into a drying oven for heating; the heated composite carpet surface carpet is fed into a forming die, and then a semi-finished carpet is obtained; the semi-finished carpet is placed on a water jet cutter cutting jig, and edge excess materials of the semi-finished carpet are cut off; the cut semi-finished carpet is taken down, hole site excess materials are removed, surface water stains are blown to be dry, and then the finished carpet is obtained. According to the method, indexes of performance of sound absorption, sound insulation and environment friendliness of a carpet assembly are achieved, and cost of raw materials is reduced due to the combination of the carpet and the EPDM.

Description

technical field [0001] The invention relates to a production method of an automobile carpet with an EPDM layer, and belongs to the technical field of automobile interior decoration processing. Background technique [0002] The car carpet is a decorative part installed on the top of the car chassis, which plays the role of sound insulation and absorbing part of the noise during driving. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are also getting higher and higher. In the prior art, performance indicators such as high sound absorption, high sound insulation, low grammage, and environmental protection of carpets have become bottlenecks, restricting the development of automotive carpets. [0003] The existing carpet mainly has...
