Technical Field

The invention relates to the field of automobile sound insulation pads, in particular to a manufacturing method of an automobile sound insulation pad with drying and anti-mildew functions.

Background

With the continuous development of social economy, the tools for riding instead of walk of people are continuously updated. As a mainstream vehicle in the society at present, the technologies of automobiles in all aspects are not continuously improved. The sound insulation pad is used as a necessary inner decoration in the automobile, and can prevent or weaken various noises from being directly transmitted into a carriage in the driving process to cause noise pollution to a driver in the automobile. However, in the daily use process of the existing automobile sound insulation pad, the existing automobile sound insulation pad does not have a drying function due to rainy weather or high air humidity, and the existing automobile sound insulation pad can be mildewed in the past.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a method for manufacturing an automobile sound insulation pad with drying and anti-mildew functions.

The technical scheme for realizing the purpose of the invention is as follows: the manufacturing method of the automobile sound insulation pad with the drying and anti-mildew functions comprises an upper decorative layer, a sound insulation layer, a drying layer and a lower decorative layer which are sequentially arranged, and comprises the following specific steps:

1) a waterproof layer is arranged on the lower surface of the upper decorative layer;

2) arranging a nano-silver antibacterial mildew-proof layer on the upper surface or the lower surface of the sound insulation layer;

3) a non-metal mineral filter material with drying and adsorption functions is filled in the drying layer;

4) sequentially placing each layer prepared in the step 1), the step 2) and the step 3) and the lower decorative layer in a forming die;

5) and 4) pressurizing the mould in the step 4), introducing water vapor, transferring to a hot-pressing mould after ventilation is finished, and pressurizing to form the mould.

Preferably, the waterproof layer in step 1) is a PE film.

Preferably, the sound insulation layer in the step 2) is a full-open-pore foam material layer.

Preferably, in the step 5), the temperature of the die is 165-175 ℃, the aeration time of water vapor is 8-11 s, and the pressure is controlled to be 4-7 Pa.

Preferably, the upper facing layer and the lower facing layer are both made of cotton materials.

After the technical scheme is adopted, the invention has the following positive effects:

(1) the nano-silver antibacterial mildew-proof layer laid on the upper surface or the lower surface of the sound-proof layer can effectively prevent the inner and outer surfaces of the sound-proof pad from mildewing caused by high humidity in a carriage in rainy days or under the condition of high air humidity. In addition, the waterproof layer laid below the upper decorative layer can prevent water vapor from entering the sound insulation pad. In addition, the inside of the sound insulation pad can be dried by the aid of the drying layer, a small amount of water vapor is prevented from entering the deep structure of the sound insulation pad, and the inside of the sound insulation pad is prevented from mildewing.

Detailed Description

(example 1)

The invention discloses a method for manufacturing an automobile sound insulation pad with drying and anti-mildew functions. The method comprises the following specific steps:

1) a waterproof layer is laid on the lower surface of the upper decorative layer, wherein the waterproof layer is a PE film;

2) the upper surface or the lower surface of puigging set up the antibiotic mould proof layer of nanometer silver, and the puigging adopts the full open cell expanded material layer.

3) A non-metal mineral filter material with drying and adsorption functions is filled in the drying layer;

4) sequentially placing each layer prepared in the step 1), the step 2) and the step 3) and the lower decorative layer in a forming die;

5) pressurizing the mold in the step 4) and introducing water vapor, transferring the mold to a hot-pressing mold after the gas introduction is finished, pressurizing and forming the mold, wherein the temperature of the mold is 165-175 ℃, the gas introduction time of the water vapor is 8-11 s, the gas outlet time of the water vapor is 15-20 s, and the pressure is controlled to be 4-7 Pa.
