Abstract

The invention relates to a production method for an automobile engine compartment heat-insulating cushion and belongs to the technical field of processing of automobile interior ornament. The production method comprises the following steps: paving raw materials, placing semi-curing reconstituted cotton into a bottom layer, and placing black non-woven fabric on an upper layer; placing the paved raw materials into a die and performing hot-press forming to obtain a semi-finished product; placing aluminum foil on the surface of the product along with the shape of the product and performing hot-press forming again to obtain a semi-finished product; placing the formed semi-finished product into a cooling jig, naturally cooling and sizing; positioning the semi-finished product and performing water cutting to obtain the required engine compartment heat-insulating cushion; and after inspecting, placing the products into boxes and placing into a storage. By the method, the problems about the performance indexes such as sound absorption, sound insulation, environmental protection, light weight and the like of the engine compartment heat-insulating cushion assembly are solved; the weight of the engine compartment heat-insulating cushion is greatly reduced; and the requirement of the whole automobile on the lightweight design is met.

Description

technical field [0001] The invention relates to a production method of an automobile engine compartment heat insulation pad, in particular to an automobile engine compartment heat insulation pad which is installed around an automobile engine and has functions of heat insulation, sound insulation and sound absorption, and belongs to the processing technology of automobile interior parts field. Background technique [0002] The car engine compartment heat insulation pad is installed around the car engine to play the role of heat insulation, sound insulation and sound absorption. 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, h...
