Abstract

The invention relates to a method for manufacturing an automobile glass wool insulating mat, which pertains to the technical filed of automotive upholstery. The method is characterized by adopting the following steps: glass wool is arranged between surface and base fabric to form base stock which is pressed, cooled and then incised by a water jet; and after being checked and proved eligible, the automobile glass wool insulating mats are packaged for storage. The insulating mat manufactured via the method has the performance indexes of sound absorption, heat resistance, light weight, high rigidity and the like, not only greatly reducing the weight of the insulating mat, but also meeting the requirements of the whole automobile on low weight design. Besides, manual arrangement of glass wool can make up for uneven glass wool density. The insulating mat manufactured via the method has the advantages of high rigidity, invulnerability, non-deformation and low cost of raw material. Therefore, the glass wool insulating mat manufactured via the method meets the requirement of the whole automobile on low cost design.

Description

technical field [0001] The invention relates to a production method of an automobile glass wool heat insulation pad, specifically for being installed in an automobile engine compartment to play the functions of heat insulation, sound insulation and beautification, and belongs to the technical field of automobile interior decoration parts. Background technique [0002] Car heat insulation pads are generally installed in the engine compartment of cars to play the role of heat insulation, sound insulation and beautification. 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 prior art, performance indicators such as high sound absorption, low grammage, and high strength of heat insulation pads ha...
