Abstract

The invention relates to a netlike reinforcing composite foaming cement board. The board consists of a netlike reinforcing part and foaming cement, wherein the netlike reinforcing part is formed by connecting upper and lower netlike reinforcing layers through a reinforcing rib. The compressive strength and tensile strength of the foaming cement board are improved. In order to improve the durability of the netlike reinforcing rib, a galvanized steel wire net or alkali-resistant grid cloth is adopted, and the grids and height of the net or the cloth are adjusted according to the requirement, so that the safety and stability of a heat preservation layer can be effectively improved, and the board is high in compressive strength, tensile strength, breaking strength, mechanical property and using stability.
