Cement foaming fireproof door and manufacturing process thereof

Abstract

The invention relates to a cement foaming fireproof door and a manufacturing process thereof. The cement foaming fireproof door includes a fireproof door panel, a fireproof door core plate, a fireproof door back plate and fireproof glue. The fireproof door core plate comprises, by weight, 180-250 parts of magnesium oxide, 250-350 parts of magnesium chloride solutions, 0.5-4 parts of gypsum, 2-10 parts of cement foaming agents, 1-5 part of superfine carbon fiber, 0.5-5 parts of silica fume powder, 5-30 parts of coal ash and 1-7 part of assistants. The manufacturing process of the cement foamingfireproof door comprises the steps that (1) slurry of the fireproof door core plate is prepared; (2) gluing is carried out; (3) pouring is carried out; (4) hardening is carried out; (5) gluing is carried out; (6) pressing is carried out; and (7) maintenance is carried out. According to the cement foaming fireproof door and the manufacturing process thereof, the fireproof door core plate, the fireproof door panel and the fireproof door back plate are bonded more tightly and firmly, the phenomena of efflorescence and empty drum are eliminated effectively, the cost is reduced, the manufacturingprocess is simple, the fireproof thermal insulation performance is good, the mechanical strength is high and harmless to human bodies.

Description

technical field [0001] The invention relates to the field of fire doors, in particular to a cement foam fire door and a manufacturing process thereof. Background technique [0002] Fire doors usually refer to doors located in some closed places such as stair walkways, elevator rooms, cable wells, smoke exhaust ducts, etc. Fire doors can meet the fire resistance stability and heat insulation within a certain period of time, and can prevent the fire from spreading and spreading. , to ensure the evacuation of personnel. The fire door core board is the material filled in the fire door. Due to the low mechanical strength and insufficient fire resistance of the existing foam door core board, it is necessary to install a fire board inside the fire door. The fire board, the fire board and the fire door panel It needs to use more glue for bonding, which increases the cost, and in the process of transportation, handling and use, fire doors are easily affected by impact and appear emp...

The fire door core board is the material filled in the fire door. Due to the low mechanical strength and insufficient fire resistance of the existing foam door core board, it is necessary to install a fire board inside the fire door. The fire board, the fire board and the fire door panel It needs to use more glue for bonding, which increases the cost, and in the process of transportation, handling and use, the fire door is vulnerable to impact and hollowing

Fire doors made of magnesite cement boards often have anti-halogen phenomenon, because the free chloride ions contained in magnesite cement boards will react with the fire door panels and cause them to corrode, reducing the service life of fire doors. Fire doors made of cotton boards can only be spliced ​​with small boards, and the aged rock wool ash is harmful to the human body
