Composite aerogel panel of aluminum alloy honeycomb panel with decorative and thermal insulation effects and preparation method thereof

A composite aerogel panel of an aluminum alloy honeycomb panel with decorative and thermal insulation effects, comprising the following layers from inside to outside:

• an aerogel thermal insulation coating layer, a first aluminum alloy plate layer, a first polypropylene hot-melt film layer, an aluminum alloy honeycomb core layer, a second polypropylene hot-melt film layer, a second aluminum alloy plate layer, a third polypropylene hot-melt film layer, and a polypropylene decorative film layer;
• wherein
• a coating for the aerogel thermal insulation coating layer is made from the following components in parts by weight:
• 60-80 parts of silica aerogel particles, 20-30 parts of polyurethane, 10-20 parts of a resin, 1.5-2.5 parts of a glass fiber, and 0.6-0.8 parts of a fluoride;
• the first polypropylene hot-melt film layer, the second polypropylene hot-melt film layer, and the third polypropylene hot-melt film layer have a same composition and are all made from the following components in parts by weight:
• 80-90 parts of polypropylene, 10-18 parts of a vinyl alcohol-ethylene copolymer, 4-12 parts of a terpene resin, 1-2 parts of zinc stearate, and 1.2-3.5 parts of an antioxidant;
• and
• in the coating for the aerogel thermal insulation coating layer, the resin is composed by mixing a C9 petroleum resin and a rosin-modified phenolic resin in a weight ratio of 9:(0.5-2).
