Embodiment 1

[0014] Embodiment 1 Car trunk cover

[0015] A new type of automobile trunk cover, comprising an EPP foam layer 3, the surface of the EPP foam layer 3 is compounded with the first hot-melt adhesive film layer 2, and the back is compounded with the second hot-melt adhesive film layer 4; the first hot-melt adhesive The film layer 2 covers the surface decoration layer 1 outside; the second hot melt adhesive film layer 4 covers the bottom surface decoration layer 5 outside. The surface decoration layer 1 is non-woven fabric, and the bottom surface decoration layer 5 is spunlace fabric. The first hot-melt adhesive film layer 2 and the second hot-melt adhesive film layer 4 are hot-melt adhesive film layers reinforced by long glass fibers. The thickness of the EPP foam layer is 15mm. The total thickness of the trunk lid is 20mm.

Embodiment 2

[0016] The preparation method of embodiment 2 automobile trunk lid

[0017] The formed EPP foam sheet is thrown away, and the two layers of hot melt adhesive film are heated to 180°C on the front and back sides respectively. After heating for 1 minute, one layer of hot melt adhesive film, EPP foam sheet and surface decoration layer Composite; Another layer of hot melt adhesive film is composited with EPP foam sheet and bottom decorative layer; the periphery is edge-wrapped.

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; a surface decoration layer covers the first hot melt adhesive film layer; and a bottom decoration layer covers the second hot melt adhesive film layer. Materials are completely environmentally-friendly, do not have any odor and can be recycled by 100 percent, the lightweight of the cover plate is improved by over 50 percent, and the bearing capacity of the cover plate meets the related weight bearing requirement of automobiles.

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. It is generally on the spare tire. The trunk cover cannot make any abnormal noise, and can be removed or flipped to facilitate the removal of the spare tire and tools. It plays a role of decoration and load-bearing. function, related items are placed on the trunk lid. The main materials of the trunk cover in the prior art are fabric composite fiberboard and fabric composite PP honeycomb panel, which have disadvantages such as not being environmentally friendly, the material cannot be recycled, the smell does not meet the requirements, and the product is heavy. Contents of the invention [0003] The problem to be solved by the present invention is a novel automobile trunk cover with the advantages of light weight, good load-bearing performance and environmental protection and a p...
