Problems solved by technology

[0003] Steel fire doors use steel as the main raw material, and steel itself has a high thermal conductivity. Although the interior of steel fire doors is filled with fireproof and heat-insulating briquetting blocks, due to the effect of metal thermal bridges, the heat insulation effect is not ideal, and the fire prevention effect is not satisfactory. Poor; at the same time, due to the poor strength of the fire-proof and heat-insulating material filled inside, it is usually not bonded to the steel during installation, so it is easy to break during use, resulting in a greatly shortened service life
The raw materials of wooden fire doors are mainly made of flame retardant wood materials, but because flame retardant and non-combustible are two concepts, they cannot reach the A1 fire performance in the national standard; It also fails to meet the fire protection level requirements of consumers.
At present, in order to improve the fire protection level of fire doors, some manufacturers add a fireproof board with a thickness of about 5mm to the inner lining board of fire doors. Less than the user's fire rating requirements

Embodiment 1

[0014] See attached figure 1 Shown, this embodiment describes a method for making a fire door made of other materials in the national standard and applied to building access doors. The fire door includes a frame 1, a panel 2, a skeleton slat 3, and a reinforced skeleton slat 4 , base plate 5 and finish layer 6. The production process of the fire door includes: S1: using a plate making machine to make a panel 2 and a bottom plate 5 with a thickness of 5 mm to 6 mm from the magnesium cementitious material at one time, wherein the sides of the panel 2 and the bottom plate 5 are respectively covered with a layer The facing layer 6 is composed of polyester non-woven fabric and PET aluminized film, and cut into corresponding fire door size specifications for later use. The thickness of the facing layer 6 is preferably 0.5mm-0.8mm, and the facing layer 6 One side of the non-woven fabric is bonded to the magnesium gel material in the panel 2 / bottom panel 5 through the chemical reacti...

Embodiment 2

[0017] See attached figure 2 As shown, what is described in this embodiment is a manufacturing method of a fire door applied to the entrance door of a building made of other materials in the national standard. The fire door includes a skeleton lath 3, a reinforced skeleton lath 4, and a molding panel 7 And the molding bottom plate 8. The production process of the fire door includes: S1: Through the molded template provided on the plate making machine, the molded panel 7 and the molded bottom plate 8 with a thickness of 5 mm to 6 mm are cast from magnesium cementitious material, and cut into corresponding The size and specifications of the fire door are spare, wherein the molding panel 7 and the molding bottom plate 8 are respectively equipped with a molding finish layer formed by a molding template; ~30mm thick plate, and the plate is cut into skeleton slats 3 and reinforced skeleton slats 4, wherein the formula of the prepared magnesia cementitious material includes: magnes...

Abstract

The invention discloses a manufacturing method of a fireproof door made of other materials in the national standard. The manufacturing method comprises the following steps of respectively manufacturing a panel and a bottom plate, which are respectively in 5 mm-6mm thickness, by magnesian cementing materials in one time through a plate manufacturing machine; manufacturing a plate in 25 mm-30 mm thickness by adopting concocted magnesian cementing materials through the plate manufacturing machine, and cutting the plate into framework battens and reinforcing framework battens, wherein the formula of the concocted magnesian cementing materials comprises the following compositions in percentage by weight: 35%-40% of magnesium oxide, 18%-23% of magnesium chlori, 5%-10% of magnesium sulfate, 20%-25% of bran coat powder, 0.2%-0.5% of phosphoric acid and 0.3%-0.4% of polycarboxylate superplasticizer, the activity of the magnesium oxide is 60%-65%, the magnesium content of the magnesium oxide is 80%-85%, and the magnesium chloride and the magnesium sulfate can be dissolved into composite brine of which the baume degree is 21%-25% as the magnesium chloride and the magnesium sulfate are stirred by adding water. After the technical scheme is adopted, the weight of the fireproof door is lighter, and the fireproof door is conveniently installed.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a method for making a fire door made of magnesia gelling material. Background technique [0002] The types of fire doors in the national fire door standard system include: wooden fire doors, steel fire doors, steel and wood fire doors, and other material fire doors specified in the national fire door material standards. The types of fire doors currently on the market are mainly wooden fire doors, steel fire doors and steel and wood fire doors. Wooden fire doors are made of wood materials soaked in flame retardant agents, and the doors are filled with fireproof and heat insulating materials, so that they have a certain fire resistance performance; steel fire doors are made of steel, and the interior is filled with There are fire-proof and heat-insulating materials, and then have a certain fire-resistant performance; the steel-wood fire-resistant door is made by mixing the abov...
