Problems solved by technology

The concave-convex structure of the core layer of the laminate will be transferred to the surface layer during melting and compounding and cause the surface layer to be uneven. It is necessary to use a thicker fabric and an adhesive with stronger adhesion to ensure a better fabric covering effect and increase usage cost
[0005] Patent CN 301381461S discloses the appearance of a three-layer hollow resin board. The surface of the board has an uneven appearance with protrusions on one side and depressions on the other. When it is used for automotive interior materials, the unevenness of the surface will lead to fabric coating requirements The height becomes higher, and only thicker non-woven fabrics can ensure a smooth appearance, and even the front and back sides need to be distinguished during processing, which increases the cost of use

Embodiment 1

[0038] The composite panel for automobile interior decoration of this embodiment is manufactured according to the above-mentioned preparation method, wherein the base material is selected as PP, the filler is talcum powder with 20% of the weight of the base material, and no high-temperature resistant additive is used;

[0039] Adjust the parameters so that K=0.5mm, D=0.4mm, L=4mm, H=8mm, and make composite board A, the thickness of the composite board is 9mm, and the surface density is 2000g / m 2 .

[0040] The commercially available thickness of the same weight is 9mm, and the surface density is 2000g / m 2 The discontinuous circular tube honeycomb panel D.

[0041] The composite panel A1 outside the range of the same structural parameters (K=0.5mm, D=0.15mm, L=3mm, H=8mm) was tested for comparison.

[0042] Under the condition of 23°C, the bending test was carried out according to GBT 1456-2005, and the measured load-bearing capacity of A was 191N, while the non-continuous ci...

Embodiment 2

[0046] The composite panel for automobile interior decoration of this embodiment is manufactured according to the above-mentioned preparation method, wherein the base material is selected as PP, the filler is talcum powder with 20% of the weight of the base material, and high-temperature-resistant additives accounting for 30% of the total weight of the raw materials are used: phosphorus-containing The mass ratio of epoxy resin, benzoxazine resin, dicyandiamide and silicon aluminate is 12:35:3:3.

[0047] Adjust and prepare the mold so that K=0.5mm, D=0.4mm, L=4mm, H=8mm, make composite board B, the thickness of the composite board is 9mm, and the surface density is 2000g / m 2 . A comparative test was carried out with the composite board B1 of the high-temperature-resistant additive with the same gram weight and the addition ratio (5:5:1:1). Tested under the GBT 1456-2005 sandwich structure bending performance test standard, the bending bearing capacity of the B composite plate...

Abstract

The invention provides a composite board for the automobile interior decoration. The composite board has smooth and uniform surfaces, the appearance of two faces is symmetrical, the manufacturing costis low, the manufacturing is convenient, the weight is light, and the composite board has relatively good mechanical properties. At the same gram weight, the load-bearing performance and rigidity arerelatively strong, the flat appearance, relatively strong peeling strength and relatively excellent performances can be obtained only by coating the board with a relatively thin fabric, and the boardespecially has relatively strong heat resistance and less attenuation of high temperature bending performance.

Description

technical field [0001] The invention relates to the field of composite material production, in particular to the field of thermoplastic resin composite material production. Background technique [0002] Non-fiber-reinforced thermoplastic honeycomb panels, due to their low cost, light weight, moderate load-bearing performance, 100% recyclability, low odor and low VOC, are increasingly used in car trunk floors, shelf boards and sound insulation panels. The wider the application. At present, the fiber-free reinforced honeycomb panels used in automotive interiors are mainly PP blister hollow panels. Such as figure 1 As shown, limited by the plastic forming process, the core layer of this type of board is generally a discontinuous honeycomb structure, with a certain distance between each honeycomb unit cell, and the core layer is a concave-convex structure with one side skin and one side without skin . Such as figure 2 As shown, when the core layer and the surface layer of ...
