Embodiment 1

[0019] a. Send the carpet raw materials between the upper mold and the lower mold of the oven for drying. The temperature of the upper mold of the oven is controlled at 425~435°C, the temperature of the lower mold of the oven is controlled at 355~365°C, and the drying time is controlled at 50 ~60 seconds, the carpet raw material is a sheet material in which a polyethylene terephthalate plastic layer, an EPDM rubber layer and a non-woven fabric layer are sequentially combined;

[0020] b. The carpet raw material after drying is sent into the lower mold of the compression molding mould, the upper mold of the compression molding mold is pressed down after the pressing plate clamps the carpet raw material, the upper mold and the lower mold compress the carpet raw material, and the pressure of the upper mold is controlled at 4~6 Mbar, cut off the remaining material along the edge of the pressing mold, control the compression molding time of the upper mold and the lower mold at 40~60...

Abstract

The invention relates to a production method of an automotive blanket, belonging to the technical field of automotive upholstery. The production method comprises the following steps: after drying fabric, closing a die, pressing and molding, removing excess materials to form a blanket body, spraying a demolding agent on a foam mold, placing the blanket body, closing the die and foaming, and checking to obtain a finished product. The invention solves performance indexes of sound insulation, light weight and high intensity of a sound insulation pad assembly, and provides the production method of the automotive blanket with simple process, high production efficiency, good sound absorption property and small weight of the produced blanket. The semi-finished product cannot be accumulated on the way, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to a production method of a carpet, in particular to a production method of an automobile carpet. Background technique [0002] Automotive interior parts are generally installed on the top of the car, the trunk, and under the floor to play the role of heat insulation, sound insulation, aesthetics, 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, low grammage, and high strength of underfloor sound-insulating mats have become bottlenecks in the development of this type of interior decoration, restricting the development of under-floor sound-insulating mats. Most ...
