Embodiment 1

[0041] The high-strength lightweight fireproof aluminum composite board includes the following steps:

[0042] (1) Preparation of flame retardant core board:

[0043] 1) Preparation of modified hydrotalcite: Put the hydrotalcite in a muffle furnace and calcinate at 480 °C for 5.5 h to obtain the calcined product, which is stored in a desiccator; boil the distilled water until it boils and keep it in a slightly boiling state. Reflux, put the calcined product into slightly boiling distilled water and stir, then add the modifier immediately, adjust the pH to 10 with NaOH solution, and continue stirring for 3 h to obtain a mixed solution; place the mixed solution statically for aging until obvious The layered mixture was suction-filtered and washed with distilled water until the filtrate was neutral. The product was dried in a drying oven at 80°C, and the dried white solid was ground into powder to obtain the improved Sexual hydrotalcite;

[0044] 2) Melt mixing: the flame-retar...
