The invention provides a compound foamed cement slab for exterior-wall external insulation systems. The compound foamed cement slab is composed of the following components in parts by mass: 140-160 parts of Portland cement, 30-35 parts of fly ash, 0.5-0.8 part of polypropylene fiber, 0.1-0.3 part of pp fiber, 2-3 parts of aluminum sulfate, 0.2-0.4 part of sodium metasilicate, 0.8-1.2 parts of lithium carbonate, 0.6-0.8 part of vermiculite, 0.3-0.5 part of sodium stearate, 0.5-0.8 part of calcium chloride, 1-1.5 parts of a foaming agent, 0.3-0.5 part of a foam stabilizer, 4-7 parts of a water repellent, and 130-150 parts of water. The invention also provides a preparation method of the compound foamed cement slab. The compound foamed cement slab disclosed by the invention overcomes the defects of large brittleness and easiness for breakage, and is strong in water resistance, good in heat preservation effect, and applicable to exterior-wall external insulation systems.
