Embodiment Construction

[0015] The production process steps of the automobile sound-absorbing and heat-insulating integral carpet of the present invention are as follows:

[0016] (1) Heating and baking: put the foamed leather into the oven to bake, the oven temperature setting: 320°C for the outer ring, 290°C for the inner ring, 270°C for the center, and the heating tube is 400mm away from the baking material tray; Baking time: 40°C seconds, reverse side 60 seconds;

[0017] (2) Suction molding: use the pre-feeding device to pre-feed and then suck, vacuum pressure setting: -0.04~-0.06Mpa, molding time 5 seconds;

[0018] (3) Cooling and shaping: Spray cooling water to cool the surface of the product rapidly, and increase the amount of cooling water for parts that are stretched greatly;

[0019] (4) Pressing and bonding: the back of the sound-absorbing and heat-insulating felt is covered with glue, and after positioning, it is pressed and bonded to the back of the foam leather;

[0020] (5) Cutting...

Abstract

The invention relates to a method for producing an automotive sound-absorption and heat-insulation integrated carpet and belongs to the technical field of automotive interior decorations. In the method, an environmentally-friendly 3.5 millimeter (including 0.8 millimeters of a toughening layer, 2.5 millimeters of a foaming layer and 0.2 millimeter of a bottom film protective layer) PVC foamed leather is mainly used and subjected to heating, baking, vacuum forming, cooling forming, 8 millimeter cotton-based sound-absorption and heat-insulation carpet compression and lamination, shearing, hole making, punching and inspection to produce a finished product. The method solves and improves the indexes, such as sound absorption, heat insulation, dust prevention, attractive appearance and easy cleaning, of the automotive carpet and makes the automotive carpet reach international advanced level-III and meet the design requirements on environmental protection, attractive appearance, comfortableness, sound absorption and heat insulation of an automotive cab. In a plastic absorption process, a pneumatic pre-feeding device is used to ensure the thickness of the foamed leather on the highly-stretched part of the large section of the product, so the overall quality of the product is improved, the quality consistency of the product is guaranteed, the production efficiency is improved greatly and the labor intensity is relieved greatly. The compression and lamination of the sound-absorption and heat-insulation carpet improve the sound and heat insulation performance of the product and make the appearance of the product smooth and elegant and touch comfortable. In the while production process of the product, no harmful matter is produced, and the product is an environmentally-friendly product.

Description

technical field [0001] The invention relates to a production method of an automobile sound-absorbing and heat-insulating integral carpet, specifically a carpet for installation in the cab of an automobile. Trim technology field. Background technique [0002] Automotive interior parts are generally installed inside the cab to beautify the cab environment, sound-absorbing, heat-insulating and dust-proof. With people's higher requirements for the environment of the car cab, environmental protection, beauty, comfort and personalization are the basic requirements for car interior parts. In the prior art, automobile carpets are all produced by foaming technology and spliced ​​in multiple pieces. The sound-absorbing and heat-insulating performance cannot be significantly improved, the dust-proof effect is poor, it is not easy to clean and affect the overall appearance, and the production cost is relatively high. The environment cannot be improved. Contents of the invention [...
