[0048] The specific embodiment part of the present invention provides a kind of preparation method of composite sandwich board, and described preparation method comprises the following steps:

[0049] (1) The glass fiber reinforced plastic board is heated, and the heating temperature of the upper and lower surfaces is different; the heated glass fiber reinforced plastic board, the polystyrene foam board and the heated glass fiber reinforced plastic board are stacked in order to obtain composite material;

[0050] (2) Compressing the combined material obtained in step (1) to obtain a composite sandwich panel.

Embodiment 1

[0053] The present embodiment provides a kind of preparation method of composite sandwich board, and described preparation method comprises the following steps:

[0054] (1) Put the PP glass fiber board into the oven to heat, the heating temperature of the upper surface is 280°C, the heating temperature of the lower surface is 300°C, heat for 100s, then take two heated PP glass fiber boards and a piece of polystyrene Foam boards are stacked in sequence in the order of heated PP fiberglass boards, polystyrene foam boards and heated PP fiberglass boards. When stacking, put the hot surface of the PP fiberglass boards close to the polystyrene foam Material, to get the composite material;

[0055] (2) Put the combined material obtained in step (1) into the mould, apply a pressure of 15MPa, keep for 60s, and obtain a composite sandwich panel; the thickness of the PP glass fiber board layer of the composite sandwich panel is 3mm, polystyrene foam board The layer thickness was 15 mm....

Embodiment 2

[0058] The present embodiment provides a kind of preparation method of composite sandwich board, and described preparation method comprises the following steps:

[0059] (1) Put the PP glass fiber board into the oven to heat, the heating temperature of the upper surface is 270°C, the heating temperature of the lower surface is 310°C, heat for 80s, then take two heated PP glass fiber boards and a piece of polystyrene Foam boards are stacked in sequence in the order of heated PP fiberglass boards, polystyrene foam boards and heated PP fiberglass boards. When stacking, put the hot surface of the PP fiberglass boards close to the polystyrene foam Material, to get the composite material;

[0060] (2) Put the combined material obtained in step (1) into the mould, apply a pressure of 14MPa, keep for 70s, and obtain a composite sandwich panel; the thickness of the PP glass fiber board layer of the composite sandwich panel is 4mm, polystyrene foam board The layer thickness was 17 mm. ...

Abstract

The invention provides a composite sandwich panel as well as a preparation method and application thereof. The preparation method of the composite sandwich panel comprises the following steps: heatinga glass fiber reinforced plastic plate at different upper and lower surface heating temperatures; stacking the heated glass fiber reinforced plastic plate, a polystyrene foam plate and the heated glass fiber reinforced plastic plate in sequence to obtain a combined material; and carrying out compression molding on the obtained combined material to obtain the composite sandwich plate. The preparation method disclosed by the invention is simple to operate, environment-friendly, low in cost and high in production efficiency, is beneficial to industrial large-scale production, and has a relatively good industrial application prospect.

Description

technical field [0001] The invention belongs to the field of automobile interior decoration, and in particular relates to a composite sandwich panel and its preparation method and application. Background technique [0002] Along with the development of economy and the progress of society, more and more private cars have entered thousands of households. While pursuing environmental protection and energy saving, car consumers also put forward higher requirements for comfort and practicality. Among them, the trunk of a car as a storage space has also become a factor for people to consider when buying a car. A trunk backup board is generally installed in the trunk of a car, which can separate the space, carry items and beautify the effect. [0003] At present, the PU spraying process is generally used to combine the honeycomb paper core and glass fiber to produce the luggage backup board, but the PU material consumption of the spraying process is large, the cost is high, and t...
