Abstract

The invention relates to an aluminum-plastic composite panel, and in particular relates to an aluminum-plastic composite panel with high rigidity and high bending strength and a preparation method of the aluminum-plastic composite panel. According to the aluminum-plastic composite panel and the preparation method thereof, firstly a PE / PP (Polyethylene / Polypropylene) core layer is reinforced by adopting coupling agent modified nanometer calcium carbonate, meanwhile the PE / PP core layer is modified by using dicumyl peroxide and triallyl isocyanurate; finally the needed panel is prepared according to a production process of the aluminum-plastic composite panel. The aluminum-plastic composite panel sequentially comprises a coating aluminum plate (1), a first type of polymer adhesive film (2), the PE / PP core layer (3), a second type of polymer adhesive film (4) and a coating aluminum plate (5) from top to bottom. The aluminum-plastic composite panel produced by the preparation method is convenient to produce, the rigidity and bending strength of an aluminum-plastic composite material produced by utilizing the modified PE / PP core layer are higher than those of a conventional aluminum-plastic composite material, and the aluminum-plastic composite panel can be widely used in transportation, decoration materials, municipal gardens and the like.

Description

technical field [0001] The invention relates to an aluminum-plastic composite plate, in particular to an aluminum-plastic composite plate with high rigidity and high bending strength and a preparation method thereof. Background technique [0002] With the enhancement of people's awareness of environmental protection, aluminum-plastic composite materials with a wide range of raw materials, environmental friendliness and recyclability have attracted more and more attention. Aluminum-plastic composite materials have the advantages of aluminum and plastic. The main features are light weight, strong and durable, and stronger impact resistance and dent resistance than aluminum alloy sheets; they can be bent freely and do not rebound after bending, so they are easy to form. When bending along the curved surface of the substrate, no special fixing is required, and it can be well adhered to the substrate, which is convenient for pasting and fixing. However, aluminum-plastic composit...
