Abstract

The invention relates to a method for producing a light automobile acoustic carpet, and belongs to the technical field of automobile part production. The light automobile acoustic carpet is obtained through paving, adsorption forming and water jet cutter cutting of an acoustic shock pad surface layer below the carpet, paving, temperature drying and pressing forming of an acoustic shock pad base material below the carpet, and paving, temperature drying, attaching forming and water jet cutter cutting of a surface carpet and a semi-finished acoustic shock pad below the carpet. The light automobile acoustic carpet produced through the method meets the index requirements of performance such as shock absorption, environmental friendliness and lightness; the weight of the automobile acoustic carpet is greatly reduced, and the requirement for the whole automobile light design is met.

Description

technical field [0001] The invention relates to a production method of a lightweight automobile acoustic carpet, belonging to the technical field of production of automobile parts. Background technique [0002] The lightweight car acoustic carpet is installed above the car floor to play the role of heat insulation, shock absorption, noise reduction, sound insulation and vehicle weight reduction. 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 getting higher and higher. In the existing technology, performance indicators such as high sound insulation, low weight, strong heat insulation, shock absorption, recyclability, and environmental protection of lightweight acoustic carpets have become bottlenecks, restricting the develo...
