Aluminum composite board and manufacturing method thereof

Abstract

The invention relates to an aluminum composite board and a manufacturing method thereof. The aluminum composite board comprises a base layer formed by sequentially leaning a plurality of aluminum profile square tubes together side by side in the horizontal direction, and aluminum boards covering the upper side face and the lower side face of the base layer respectively. The aluminum boards and thealuminum profile square tubes are bonded together through PUR glue, a ventilation system is constructed between the aluminum boards and the aluminum profile square tubes, external air permeates through the ventilation system, moisture existing in the air reacts with the PUR glue, chain extension is conducted, and a high-molecular polymer with high cohesion is generated. The aluminum board and thealuminum profile square tube are bonded together. The aluminum composite board is composed of the aluminum profile square tubes and the aluminum boards, and the prepared board is stable in performance, seamless in compounding, good in flatness, excellent in hand feeling and sound, low in deformation coefficient and environmentally friendly, has good waterproof, fireproof, insect-proof, anti-corrosion and high-low-temperature-resistant effects and can be used as a wall board or a furniture board. The production process is simple, high in efficiency, high in productivity and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite board suitable for home decoration and furniture products. Background technique [0002] Traditional composite panels are mainly wood composite panels, which have defects such as too small format size, cumbersome production process, large deformation coefficient, and easy cracking and deformation, which greatly restrict the development and application of this industry. The reasons for these defects are: the materials of the upper and lower layers of the wood composite board are different, so the coefficient of contraction and expansion is also different, so there will be quality problems such as panel cracking, adhesive surface opening, and serious deformation during use. [0003] With the development of the economy and people's demand for a healthy life, more and more attention has been paid to environmental protection issues, and more and more attention ...
