Abstract

The invention relates to the technical field of aluminum-plastic composite boards, and in particular to a high-temperature resistant aluminum-plastic composite board. The high-temperature resistant aluminum-plastic composite board comprises a high-temperature resistant board core, upper and lower two aluminum board layers, and adhesive layers used for bonding the high-temperature resistant board core and the aluminum board layers. Preparation steps of the composite board comprise: mixing raw materials of the high-temperature resistant board core: adding 70-80 parts of a matrix resin, 20-30 parts of silicon nitride, 12-20 parts of modified sepiolite, 10-15 parts of modified sodium montmorillonite, 8-15 parts of nano-magnesium hydroxide, and 1-3 parts of a silane coupling agent into a high-speed mixer, and then performing full stirring for 10 min at a stirring speed of 120 r / min. By adding ingredients in the interior of the matrix resin, a uniform-dispersed sepiolite-sodium montmorillonite-nano-magnesium hydroxide copolymer is formed, heat transferred by the resin can be absorbed under the high temperature environment, the inner layer temperature distribution is uniform during the entire heat absorption process of the aluminum-plastic board, no temperature difference can be appeared, and thereby the bending phenomenon cannot be appeared due to stress concentration. At the same time, the peeling strength of the aluminum-plastic composite board can be effectively improved by the preparation method, so that the overall quality is relatively good.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic composite panels, in particular to a high-temperature-resistant aluminum-plastic composite panel. Background technique [0002] The aluminum-plastic composite panel is a three-layer composite panel with plastic as the core layer and aluminum on both sides. The surface of the product is covered with a decorative and protective coating or film as the decorative surface of the product. When evaluating various performances of aluminum-plastic composite panels, the physical and chemical properties of the core layer determine the performance of the entire aluminum-plastic composite panel. [0003] With the wide use of aluminum-plastic composite panels in the field of home decoration, its fireproof and high-temperature resistance performance is particularly important, and the fireproof performance of aluminum-plastic composite panels is completely determined by the core layer. The core layer of...
