Abstract
Description
technical field
[0001] The invention relates to the field of fire doors, in particular to a composite fire door and a manufacturing process. Background technique
[0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. Composite fire doors usually refer to the structure of steel and wood composite molding, which has the characteristics of good fire prevention effect and light weight; in the existing composite fire doors, when the fire door is closed, the door panel directly hits the airtight strip, which is easy to b...
