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.
