Embodiment 1

[0027] Such as Figure 1-3 As shown, a kind of high-load vehicle trunk spare tire cover provided in this embodiment includes a PU layer 1, and a metal sheet 2 is compounded on the surface of both sides of the PU layer 1. The metal sheet 2 on the side is compounded with a vehicle decorative fabric layer 3, and the surface of the PU laminated board is covered with a non-woven fabric layer 4 except for the vehicle decorative fabric layer 3. Both the peripheral edge of the layer 4 and the peripheral edge of the automotive decorative fabric layer 3 are pressure-bonded.

[0028] Simultaneously, the present invention also provides a method for preparing a spare tire cover for a high-load vehicle trunk as described above, which uses a metal blanking machine or a high-pressure water cutting machine, a foaming machine and a hydraulic press, and is characterized in that it includes the following steps:

[0029] Step 1, punching; the metal sheet 2 is punched and formed by a metal punchin...

Embodiment 2

[0034] The general structure of the spare tire cover for a high-load vehicle trunk provided in this embodiment is consistent with that of Embodiment 1, but in order to facilitate the PU lamination after the above-mentioned PU laminated board is used on the car body The overall lifting and flipping operation of the board, such as Figure 4 and Figure 5 As shown, the PU laminated board in this embodiment is also provided with a handle installation hole 5, and a handle 6 is connected to the handle installation hole 5.

[0035] The preparation method of the spare tire cover of a high-load vehicle trunk provided in this embodiment is also similar to the preparation method of the spare tire cover of a high-load vehicle trunk provided in the embodiment. Consistent, but in this embodiment, considering that the handle installation hole 5 has been opened on the PU laminated board, the PU foamed laminated body, automotive decorative fabric and non-woven fabric base are used in step 3 o...

Abstract

The invention discloses a laminated plate for cars and particularly relates to a high-load spare tire cover plate for a car trunk. The high-load spare tire cover plate comprises a PU layer. Metal sheets are composited to the surfaces of the single side or double sides of the PU layer. A car decoration fabric layer is composited to the metal sheet on one optional side. A non-woven fabric layer wraps the surfaces of the areas, other than the area covered with the car decoration fabric layer, of the PU laminated plate. The periphery of the non-woven fabric layer is adhered to the car decoration fabric layer under pressure. The invention further provides a production method of the high-load spare tire cover plate. The high-load spare tire cover plate has the advantages that the structural strength and toughness of the PU laminated plates for the cars are increased, and the high-load spare tire cover plate is high in plate strength, good in toughness, good in bearing stability, little in limitation as car plates, and the like.

Description

technical field [0001] The invention relates to a laminated board for vehicles, in particular to a spare tire cover plate for a high-load vehicle trunk and a preparation method for a spare tire cover plate for a high-load vehicle trunk. Background technique [0002] Earlier, the applicant submitted a Chinese utility model patent application document with the application number 201220748359.3 to the State Intellectual Property Office. In this patent application document, a glass fiber reinforced laminated PU composite material has been disclosed in detail. The sheet film is bonded and fixed to the substrate, and glass fiber filaments are evenly spread on the plastic sheet film. In the above-mentioned glass fiber reinforced laminated PU composite structure, PU material is used to replace common paper honeycomb panels. PU material has better energy absorption, noise reduction and shock absorption performance, and more importantly, PU material is better than paper The high-qua...
