The manufacturing method of the fireproof door core board is free of exhaust gas emission in the process, and accords with the requirements of development of environmental development.

Description

technical field [0001] The invention belongs to the technical field of fire door core boards, and in particular relates to a fire door core board material, a fire door core board and a manufacturing method 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 can prevent the spread of flames and prevent the flow of combustion smoke 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, buildings with fire protection requirements have fire doors. At present, most fire protection design codes in China clearly require the use of fire doors. The research, development and production of fire door products have played a positive role in ensuring the safety of people's lives and property. China's fire door market started late, but developed rapid...
