Abstract
The invention discloses a brazing aluminum plate for a sound-insulating honeycomb panel, which relates to the technical field of aluminum foilcalendering. The aluminum plate includes a core layer and a brazing layer; the core layer includes two or more alloylayers, and the alloy layer includes aluminum and other metals or non-metallic casting and rolling, the brazing layer includes aluminum and other metals or non-metallic combinations, the manufacturing method of the brazing aluminum plate includes the following steps: melting and casting the core layer material and the brazing layer material respectively and obtaining Respective blanks; rough rolling and annealing the core layer blank and brazing layer blank respectively to obtain their respective semi-finished products; rolling and compounding the core layer semi-finished product and brazing layer semi-finished product to obtain a composite blank; rough rolling and trimming the composite blank , to obtain the embryonic product; molding the embryonic product to obtain the finished product; check the quality of the finished product, and pack the qualified finished product. The present invention has a short process flow, high production efficiency, uniform compounding rate in the width direction of the strip material and satisfies a large compounding rate. Production of welded aluminum plates.
Description
technical field [0001] The invention relates to the technical field of aluminum foil rolling and manufacturing, in particular to a brazed aluminum plate for a soundproof honeycomb panel and a manufacturing method thereof. Background technique: [0002] The traditional sound insulation honeycomb panel adopts aluminum alloy bottom plate and panel, and the hexagonal aluminum foil honeycomb core or foamed aluminum is bonded with adhesive in the middle, and the honeycomb panel is formed by hot pressing; The hexagonal or special-shaped PVC honeycomb core or PVC foam is bonded to form a honeycomb panel by hot pressing. The board has low compressive resistance, poor impact resistance and poor sound insulation effect, especially the board prepared by PVC material and adhesive has low fire resistance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a brazed aluminum plate for sound insulation honeycomb panels and a manufacturing method thereof, ...
