The invention relates to the technical field of cement boards, especially to a sandwich composite foamed cement board and a making method thereof. The sandwich composite foamed cement board comprises: an upper foamed cement board, a bonding layer wrapped with an anti-cracking material and a lower foamed cement board. The bonding layer is boned with the upper foamed cement board and the lower foamed cement board. According to the invention, an interlayer is disposed between the two layers of foamed cement boards, and the interlayer has the anti-cracking material structure, so that the foamed cement board has reinforced strength and good toughness, is difficult to break, and has good thermal insulation performance, and can greatly reducing the expenses of cooling and heating, and other electric power and burning, thus being the optimal choice for energy saving. The sandwich composite foamed cement board has fast construction speed, is easy and convenient to install, can greatly shorten the construction period, has good sound insulation, waterproof and fireproof performance, and good surface decorative performance. The wallboard surface planeness is good, and can be directly used for sticking wallpaper and wall bricks and spraying. With low comprehensive cost, the sandwich composite foamed cement board is environment-friendly, energy saving and waste utilizing, and can increase the available building area.
