The invention discloses a composite foamed cement board with a good sound insulation effect. The composite foamed cement board is prepared from the following components in parts by mass: 120-130 parts of portland cement, 15-20 parts of coal ash, 3-5 parts of expanded perlite, 0.5-0.8 part of vermiculite, 0.1-0.3 part of polypropylene fiber, 0.4-0.6 part of sodium metasilicate, 0.3-0.5 part of calcium stearate, 2-3 parts of aluminum sulfate, 0.3-0.5 part of calcium chloride, 1-1.5 parts of a foaming agent, 0.3-0.5 part of a foam stabilizer, 3-5 parts of a water repellent and 110-115 parts of water. The invention also provides a preparation method of the composite foamed cement board. The composite foamed cement board provided by the invention is favorable in heat insulation and sound insulation effects and suitable for a heat insulation system for an exterior wall.
