Embodiment 1
[0038] The fire door core boards of Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, and Embodiment 5 are made according to the different component formulas in Table 1, and the heat insulation performance of the door core board is reflected in the fire door firing experiment. The above is, after subtracting the ambient temperature, the time when the average temperature of each point on the unfired surface does not exceed 140°C and the time when the maximum temperature does not exceed 180°C is called the fire resistance limit time, and the longer the value, the better.

The invention discloses a composite nano-hydroxyl alumina flame-retardant insulation board and a manufacturing method and application thereof. The composite nano-hydroxyl alumina flame-retardant insulation board comprises the following components in percentage by weight: 12-18 percent of nano-hydroxyl alumina flame retardant, 50-55 percent of perlite, 15-18 percent of magnesium oxide binder, 16-18 percent of magnesium chloride binder and 30-45 percent of water. The composite flame-retardant insulation board is an inorganic nano-hydroxyl alumina flame-retardant insulation board with low water content, and can be used for making a fireproof door core board and the like. The fireproof door core board has the characteristics of high fire resistance, long fire resistance time, high compressive strength, stable performance, insulation of sound and heat, low heat conductivity coefficient, no toxicity, freeness from nuisance and pollution, excellent environmental protection performance and high machinability.
Description
technical field [0001] The invention relates to a fire-proof and flame-retardant material, in particular to a composite nano-hydroxide flame-retardant insulation board, a preparation method and an application thereof. Background technique [0002] Fire doors are doors made of fire-resistant and flame-retardant materials with fire-resistant stability, integrity and heat insulation. It is suitable for the passage of people, and it can prevent the flame from spreading and prevent the delay of combustion in the event of a fire, and it can also be used as a seal when the positive air supply system is working. Today, with the increasingly mature fire protection technology, basically buildings with fire protection requirements have fire doors. At present, most of the domestic fire protection design codes have clear requirements for the use of fire doors in buildings. [0003] In 2009, my country set new standards for fire doors. The classification of fire doors is changed from t...
