Problems solved by technology

On the molded parts that need to be pasted with decorative fabrics, since the surface of these parts has some heat insulation, sound insulation or other polyurethane substances, after the fabrics are pasted, it is easy to produce material penetration, and the surface materials of the molded parts penetrate through the layers of the fabric. The surface will be wrinkled, blistered, uneven, etc.
[0003] At the same time, due to the coating and scraping method used in the production method of the fabric composed of the general PVC-based material layer and the knitted fabric layer, it is foamed and plasticized after the patch is applied. Due to the high temperature, the adhesive is easy to melt, making the base fabric Layers come off easily

Embodiment Construction

[0011] The specific embodiments of the present invention are described below in conjunction with the drawings, such as figure 1 Shown:

[0012] An automotive interior fabric used for deep-drawing molding. The surface layer 1, the foamed layer 2, the sandwich layer 3, the foamed layer 4, the adhesive layer 5, and the base fabric layer 6 in sequence. The sandwich layer 3 is a dense structure, the base fabric layer 6 is a bidirectional elastic cloth, and the adhesive layer 5 is made of polyurethane adhesive.

[0013] Such as figure 2 As shown, specify the production method:

[0014] Using the method of coating and scraping, the raw material is PVC mixture. The dense layer 1 is first coated. After gelling and cooling, the foaming layer 2 is coated. After the gelling and cooling, the sandwich layer 3 is again coated. It is a dense layer structure. After gelling and cooling, the foaming layer 4 is coated; then it enters the oven for plasticizing and foaming, and the foaming and plastici...

Abstract

The invention relates to an interior decorative lining used for deep drawing and shaping, successively comprising a PVC (Poly Vinyl Chloride) base batch layer and a foundation layer, wherein the PVC base batch layer successively comprises a surface layer, a foaming layer 2, a sandwich layer, a foaming layer 4 and a binder layer. The invention also relates to a production method of the lining. The lining is characterized in that a blocked layer is formed between the sandwich layer, so that substance on the shaped surface of an automobile part does not penetrate through the lining, and the lining does not wrinkle, does not foam and is even and the like after the lining is stuck.

Description

Technical field [0001] The invention relates to an automotive interior fabric and a production method thereof, in particular to an automotive interior fabric for deep drawing forming and a production method thereof. Background technique [0002] The current automotive interior fabrics are mainly composed of a PVC-based batch material layer and a knitted fabric layer. On the molded parts that need to be pasted with decorative fabrics, because the surface of these parts has some heat insulation, sound insulation or some other polyurethane materials, after the fabric is pasted, it is easy to produce seepage, and the surface material of the molded part penetrates through the layers of the fabric, The surface will be wrinkled, blistered, uneven, etc. [0003] At the same time, the scraping method used in the production method of the fabric composed of the general PVC-based batch material layer and the knitted fabric layer is all foamed and plasticized after the cloth is attached. Due t...
