Manufacturing method of automobile sound insulation pad with drying and anti-mildew functions

Abstract

The invention relates to a manufacturing method of an automobile sound insulation pad with drying and anti-mildew functions. The manufacturing method is characterized in that the automobile sound insulation pad comprises an upper facing layer, a sound insulation layer, a drying layer and a lower facing layer which are arranged in sequence, and the manufacturing method comprises the following specific steps: 1) arranging a waterproof layer on the lower surface of the upper facing layer; 2) arranging a nano-silver antibacterial mildew-proof layer on the upper surface or the lower surface of the sound insulation layer; (3) the drying layer is filled with a non-metal mineral filtering material with drying and adsorption functions; (4) sequentially placing the layers prepared in the step (1), the step (2) and the step (3) and the lower facing layer in a forming mold; and (5) pressurizing the mold in the step (4), introducing water vapor, transferring to a hot-pressing mold after the ventilation is finished, and pressurizing to mold. The invention aims to overcome the defects in the prior art, and provides the manufacturing method of the automobile sound insulation pad with the drying and anti-mildew functions.

Description

technical field [0001] The invention relates to the field of automobile sound-insulating mats, in particular to a method for manufacturing an automobile sound-insulating mat with the functions of drying and anti-mildew. Background technique [0002] With the continuous development of social economy, people's means of transportation are also constantly updated. As the current mainstream means of transportation in society, automobiles are not constantly improving in all aspects of technology. As a necessary interior decoration in the car, the sound insulation pad can avoid or reduce various noises directly transmitted to the compartment during driving, causing noise pollution to the driver in the car. However, in the daily use of existing car sound insulation mats, due to rainy weather or high air humidity, and existing sound insulation mats do not have a drying function, the sound insulation mats will become mildewed if things go on like this.
