Problems solved by technology

This increases the energy consumption in the production process; the relative period is relatively long, and at the same time, because the production beats of the two processes are inconsistent, that is, the screw extruder with continuous high extrusion capacity needs to cooperate with the molding process of forming and cooling in the gap, which greatly reduces extrusion. The efficiency of the machine greatly reduces the overall production efficiency; in addition, the initial equipment investment of this method is relatively large, which is not suitable for the production of small batches and multi-variety products.

Embodiment 1

[0045] (A) The specific composition of the automotive interior composite material shown in Figure 1 is as follows:

[0046] The first layer of fabric (1) is a polyester fiber non-woven blanket of 600 g / m2

[0047] The second release layer (2) is a polyester fiber non-woven fabric of 120 g / m2

[0048] The third sandwich layer (3) is composed of a sheet of 2400 g / m2 hot melt felt, in which the weight percentage of polypropylene fiber and recycled cotton fiber is 50%:50%

[0049] The fourth release layer (4) is 120 g / m2 polyester fiber non-woven fabric

[0050] The fifth bottom material layer (5) is 400 g / m2 polypropylene fiber non-woven blanket

[0051] (B) The specific steps of the above-mentioned composite material manufacturing are as follows:

[0052] (1) Lay the sheets to be heated in layers from bottom to top: the release layer (4) is placed on the lower layer, and the sandwich layer (3) is selected from hot melt felt, placed on the second layer, and the upper layer is the rel...

Embodiment 2

[0056] (A) The specific composition of the composite material in the interior of the automobile as shown in Figure 2 is as follows:

[0057] The first fabric layer (1) is a polyester fiber non-woven blanket of 600 g / m2

[0058] The second release layer (2) is a polyester fiber non-woven fabric of 120 g / m2

[0059] The third sandwich layer (3) is composed of two kinds of sheets: 2000 g / m2 hot-melt felt (3a) and 400 g / m2 polypropylene felt (3b), among which the polypropylene fiber in the hot-melt felt and recycled The weight percentage of cotton fiber is 40%:60%, and (3a) is placed on (3b).

[0060] The fifth release layer (4) is 120 g / m2 polyester fiber non-woven fabric

Abstract

The invention relates to a composite material used in vehicle inner decoration and relative producing method. Said composite material is formed by five or six non-woven sheets as surface layer, de-molding layer, filled layer, de-molding layer and base material layer. Wherein, the filled layer can be formed by hot-melt felt (3a) and polypropylene felt (3b). The producing method comprises that using the de-molding layer (4) as lower layer, the filled layer (3) as intermediate layer and the de-molding layer (2) as upper layer to be piled and arranged between the upper and lower heating plates of heat device; adhering said three layers after low-pressure high-temperature heating into the frame of soft-sandwich type; moving said frame into the lower mould of molding mould and above the base material layer (5); coating the surface layer (1) on the frame; closing the mould to be pressurized and shaped; cutting the hole and edge; and lifting upper mould to attain the final product. The invention has the advantages of lower cost, un-deformed product, high strength, impact resistance, welding availability, short producing process and high efficiency.

Description

Technical field [0001] The invention relates to a composite material for automobile interior decoration and a manufacturing method thereof in the industrial textile manufacturing industry of the textile industry, in particular to a composite material for automobile interior decoration of unequal thickness and a manufacturing method thereof. The composite material is widely used in structural door panel materials and other structural interior materials in car interiors. Background technique [0002] With the rapid development of the world economy and the continuous improvement of people's lives, the automobile industry is developing rapidly, the production of cars is changing with each passing day, and the models are constantly being updated. People's requirements for cars are not only beautiful appearance, but also pay more attention to the comfort, integrity and functionality of the interior decoration. These materials are required not only to have the characteristics of heat in...
