Technical Field
[0001] The invention belongs to the technical field of building materials, and particularly relates to a fireproof and heat-insulating cement foam board and a preparation method thereof. Background Art
[0002] With the continuous development of the construction industry, the performance requirements for building materials are getting higher and higher. Fireproof and thermal insulation materials play a vital role in construction. They can not only improve the fire resistance of buildings, but also effectively reduce energy consumption and achieve the goal of energy saving and environmental protection.
[0003] Cement foam board is a cement-based lightweight porous inorganic fireproof insulation board made by mixing foam and cement and pouring it into shape, and then curing it. It uses the non-combustibility of cement and the large number of closed pores in concrete to achieve the effects of fireproofing, lightness and insulation. It is currently the best product for fireproof isolation zones. At present, cement foam board has been widely used in large-span industrial plants, warehouses, large machine garages, stadiums, exhibition halls, airports, large public facilities, mobile homes, residential mezzanines, and exterior wall insulation of civil residences.
[0004] However, the common insulation materials on the market are mainly organic materials such as polystyrene foam boards and polyurethane foam boards. Although these materials have good insulation performance, they have poor fire resistance. In the event of a fire, they are easy to burn and release a large amount of toxic gases, posing a serious threat to people's lives and property. Traditional inorganic insulation materials such as rock wool and glass wool, although they have good fire resistance, have strong water absorption, and the insulation layer and insulation strips are easy to fall off, which not only increases the manufacturing cost of the insulation materials, but also poses certain safety hazards.
[0005] Therefore, it is of great practical significance to develop a building material that has both good fire resistance and excellent thermal insulation performance. Summary of the invention
