Abstract
The utility model discloses a kind of automobile-used laminated board, the automobile-used PU laminated boards of particularly a kind of top load, including PU layers, metal sheet is compounded with the unilateral or bilateral layer surface of the PU layers, the automobile-used decorative cover bed of material is compounded with the metal sheet of any side；Meanwhile, a kind of preparation method of automobile-used top load PU laminated boards a kind of as described above is additionally provided in this utility model.The technical problem of " structural strength and toughness that lift automobile-used PU laminated boards " is which solved, possesses that timber intensity is high, good toughness, bearing stability are good, as the automobile-used sheet material series of advantages such as use limitation little.
Description
Technical field
This utility model is related to a kind of automobile-used laminated board, the automobile-used PU laminated boards of particularly a kind of top load.
Background technology
In the early time, applicant is real to the China that State Intellectual Property Office have submitted a Application No. 201220748359.3
Use new patent application documents.A kind of fiberglass reinforced type lamination PU has been disclose in detail in the patent application document to be combined
Material, which includes substrate, and the upper and lower surface of substrate is provided with plastic film, and described substrate is PU composite plates, the modeling of upper and lower surface
Tablet film is fixed with substrate bonding, and described the upper of plastic film is uniformly covered with glass fiber.A kind of above-mentioned fiberglass reinforced type
The cellular board of the papery for using PU material substitutions common in lamination PU composite structure, PU materials have more preferable energy-absorbing, noise reduction
And damping performance, it is often more important that PU materials have more preferable mouldability than paper material, then by the upper of plastic film
Laying glass fiber, further improves intensity and toughness so as to possess preferable performance and service life.
But in practice process, it is found by the applicant that the intensity of above-mentioned such fiberglass reinforced type lamination PU composite and tough
Degree is all still not ideal enough.
The content of the invention
The purpose of this utility model is to put forward a kind of automobile-used PU laminations of top load to solve above-mentioned the deficiencies in the prior art
Plate, and the preparation method of the automobile-used PU laminated boards of the top load.
To achieve these goals, the automobile-used PU laminated boards of a kind of top load designed by this utility model, including PU layers,
Metal sheet is compounded with the unilateral or bilateral layer surface of the PU layers, it is preferred that in the bilateral layer surface of the PU layers
Composition metal sheet material, is compounded with the automobile-used decorative cover bed of material on the metal sheet of any side.
Above-mentioned mentioned PU materials are the abbreviations of polyurethanes, and English full name is polyurethane, and it is one
Macromolecular material is planted, is current material.
The metal material of above-mentioned mentioned metal sheet can adjust according to needs of production, and preferred intensity and toughness are equal
Relatively good sheet metal, or copper or aluminium thin plate.
Meanwhile, a kind of preparation method of the automobile-used PU laminated boards of top load as described above is additionally provided in this utility model, is adopted
Metal clicker press machine or high-pressure water-cutting machine, foaming machine and hydraulic press, is characterized in that comprising the following steps：
Step one, punching；Size and dimension of the metal sheet using metal clicker press machine or high-pressure water-cutting machine on demand enters
Row punching or excision forming；Sheet metal of the preferred thickness for 0.10-0.15mm；
Step 2, foaming；Wherein, first the metal sheet being punched in abovementioned steps one or cutting is obtained is put into and is sent out
The foaming mould of bubble machine is interior and positions, matched moulds rear-inclined；Then, PU foamed materials are injected and is foamed in foaming mould；
Step 3, molds feeding.
The hardness and intensity of above-mentioned middle PU foaming is according to A：The ratio ranges of B, i.e. polyurethane combination material（Polyhydric alcohol W5453/
101C-A）：Polyurethane combination material（Isocyanates W5313/101C-B）Ratio ranges carry out selection setting, for car boot
The application of case carpet, the preferred density of the PU foamings is：0.2-0.55g/cm3.
A kind of above-mentioned designed automobile-used PU laminated boards of top load, substitute the honeybee of common papery using PU layers in its structure
Nest plate, PU materials have more preferable energy-absorbing, noise reduction and damping performance, it is often more important that PU materials have more than paper material
Good mouldability；In addition, being combined metal sheet in the unilateral or bilateral layer surface of PU layers, it is contemplated that metal material is high-strength
The characteristic of degree and wilfulness, causes above-mentioned automobile-used PU laminated boards structure to compare more traditional automobile-used PU laminated boards with relatively more preferable
Intensity and toughness, lift its overall performance and service life.
In order that after above-mentioned PU laminated boards are specifically used on car body, facilitating the overall lifting upset behaviour of PU laminated boards
Make, handle mounting hole site is additionally provided with above-mentioned PU laminated boards, is connected with handle in the handle mounting hole site.
The automobile-used PU laminated boards of a kind of top load that this utility model is obtained, which possesses, and timber intensity is high, and good toughness is carried
Good stability, as the automobile-used sheet material series of advantages such as use limitation little.
