Embodiment 1

[0015] Example 1 Car trunk cover

[0016] A new type of car trunk cover, comprising an EPP foam layer 3, the surface of the EPP foam layer 3 is compounded with a first hot-melt adhesive film layer 2, and the back side is compounded with a second hot-melt adhesive film layer 4; The film layer 2 covers the surface decoration layer 1 ; the second hot melt adhesive film layer 4 covers the bottom surface decoration layer 5 . The surface decoration layer 1 is a non-woven fabric, and the bottom surface decoration layer 5 is a spunlace cloth. The first hot-melt adhesive film layer 2 and the second hot-melt adhesive film layer 4 are long glass fiber reinforced hot-melt adhesive film layers with a long glass fiber mat in the middle and a hot melt adhesive film on both sides. The thickness of the EPP foam layer is 15mm. The overall thickness of the trunk lid is 20mm.

[0017] The surface decoration layer is non-woven or needle-punched carpet; the gram weight is 200-600g / m 2 .

[001...

Embodiment 2

[0020] Embodiment 2 The preparation method of car trunk cover

[0021] Throw the formed EPP foam sheet, heat the front and back sides of the two layers of hot-melt adhesive film to 180°C, and after heating for 1 minute, a layer of hot-melt adhesive film, EPP foam sheet and surface decoration layer Compounding; another layer of hot melt adhesive film is compounded with EPP foam sheet and bottom surface decorative layer; the periphery is edge-wrapped.

Embodiment 3

[0022] Example 3 Bearing force test

[0023]

[0024] It can be seen from the above test that the trunk cover of the automobile is also excellent in bearing capacity on the basis of environmental protection and lightness.

Abstract

The invention provides a novel car trunk cover plate and a preparation method thereof. The novel car trunk cover plate comprises an EPP foaming layer, wherein the surface of the EPP foaming layer is compounded with a first hot melt adhesive film layer, and the back of the EPP foaming layer is compounded with a second hot melt adhesive film layer; the outside of the first hot melt adhesive film layer is covered by a surface decorating layer, and the outside of the second hot melt adhesive film layer is covered by a bottom decorating layer. The used materials are completely environmentally friendly, and have no peculiar smell, any organic adhesive is not used in the production process, the in-car air quality assessment guideline is fully met, materials can be thoroughly recycled, and the lightweight of a product is enhanced by more than 50%; meanwhile, the load-bearing capacity of the product complies with the relevant weight load-bearing requirements of cars.

Description

technical field [0001] The invention relates to a novel automobile trunk cover and a preparation method thereof. Background technique [0002] The trunk cover is the cover in the trunk of the car, generally on the spare tire. The trunk cover can not have any abnormal noise, and can be removed or flipped to facilitate the removal of the spare tire and tools, and is used for decoration and load-bearing. function, the relevant items are placed on the trunk lid. The main materials of the luggage cover in the prior art are fabric-compound fiberboard and fabric-compound PP honeycomb panel, which have disadvantages such as being unenvironmental, unrecyclable materials, unsatisfactory odor, and heavy product weight. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is a new type of automobile trunk cover plate with advantages of light weight, good load-bearing performance, environmental protection and the like, and a preparation method thereof. ...
