Problems solved by technology

However, rock wool is used for internal hollow filling, which does not meet the requirements of the new national GB12955-2008 standard
Rock wool is solid, if the workers operate carelessly, it will cause gaps and bring fire hazards at the same time
[0005] For example, application number: 200710093204.4 discloses a method and structure of a fireproof door and frame, which uses a pouring method to form a cladding layer on both sides of the door leaf by using a layer of fireproof slurry and a layer of glass fiber on the skeleton surface of the door and frame. The frame is installed in the middle, and the hollow part of the frame is filled with fireproof slurry, and the door leaf formed by the integral casting is not easy to deform after being heated, and the fireproof slurry is added with adhesive to make the attached fireproof board on the surface of the door leaf not easy to crack, but The overall use of fire-resistant slurry casting increases the weight of the entire door leaf, and the product takes a long time to fix and form, which increases the difficulty of construction, and the lack of flexibility is prone to breakage, and the glass fiber will age after being stored for a period of time and its strength will decrease, which is also harmful to people. skin irritation
[0006] At present, the fire-proof door leaf and the interior of the cabinet frame are composed of several parts. The whole door leaf does not form a complete door leaf. , was coaxed to pass the customs, but the passing rate of the sampling inspection on the project site was very low, resulting in completely different products submitted for inspection and random inspection, which brought fire hazards

Embodiment 2

[0035] Embodiment 2: be respectively magnesium oxide 30% by weight: magnesium chloride solution 50%: modifying agent 3%: short fiber 1%: fly ash 5%, all the other add wood sawdust, this example adopts light material wood sawdust to further The weight of the entire inorganic cementitious material is reduced, and the gaps of the wood sawdust soaked in magnesium chloride solution are completely filled with flame retardants, so that the entire door leaf is completely isolated from heat transmission due to the uniform distribution of flame retardant materials when it encounters fire.

Embodiment 3

[0036] Embodiment 3: be respectively magnesium oxide 60% by weight: magnesium chloride solution 17%: modifying agent 0.5%: short fiber 1%: fly ash 5%, all the other add 8% vitrified microbead particle and 8.5% glass microsphere beads. In this example, the use of light-weight material vitrified microspheres and glass microspheres can enhance the compression resistance of the entire fire door in the context of the aforementioned beneficial effects, and is suitable for buildings that require hardness and strength.

Embodiment 4

[0037] Embodiment 4: be respectively magnesium oxide 35% by weight: magnesium chloride solution 40%: modifying agent 0.5%: short fiber 1%: fly ash 5%, all the other add 3% ceramic mud ball, 1.5% glass microsphere, 3% wood sawdust, 3% slag, 3% expanded perlite particles, 2% high phosphorus soil, 3% plant fiber. This example not only has high fire resistance, but also has the characteristics of light weight, heat insulation, high strength and high hardness.

[0038] The magnesium chloride solution glassy degree is 22 °-29 ° among the above each embodiment.

[0039] In this program, when filling the space of the keel skeleton, the inorganic gelling material is foamed and mixed, and the foaming agent used in the foam is 85% by weight of animal protein, 14.9% of sodium lauryl sulfate solution and a foam stabilizer 0.1% mixed, this combination can make the generated foam have the best stability, not easy to burst and the volume of the foam is not far apart. The foam stabilizer is ...

Abstract

The invention relates to a cast-in-situ fire-proof door and a method for manufacturing same, wherein the door comprises: a frame, panels, a keel frame and inorganic cement for filling, outer surface of the frame and one side of the two panels is in-situ cast with fireproofing inorganic cement coatings, the keel frame is installed between the sides cast with inorganic cement of the two panels, blowing agent is added in the liquid inorganic cement, which is cast in-situ in the chamber formed by the keel frame, contact surface of the frame and door leaf has a seal groove for installing sealing strip, and the door leaf and the frame cast-in-suit is pressed and shaped by a pressure device. The fire-proof door leaf and the frame of the invention avoids crack and nonuniform filling and nonuniformmixing of material in prior art because of employing fire-proof material, mass of inorganic cement with bubbles is filled in the keel frame, thereby lightening the fire-proof door, having good heat insulating effect, increasing density of the whole fire-proof door, and greatly strengthening fireproofing performance.

Description

technical field [0001] The invention relates to a kind of building fireproof equipment, in particular to a fireproof door with fireproof function made of cast-in-place inorganic gelling material and a manufacturing method thereof. Background technique [0002] At present, in the fire doors of the existing technology, the structure of the door leaf adopts the method of filling solid flame-retardant materials in the hollow door leaf. The filling materials are generally materials such as rock wool and expanded perlite. The fire doors made by this method are prone to uneven filling, Various flame retardant materials are mixed unevenly, and the hollow door is filled with gaps or dead corners, which reduces the fire resistance of the entire fire door. Even if the above conditions do not occur, the overall fire resistance of the fire door manufactured by this method is not high. The fire resistance time is far lower than the current new national standard. Some use wooden materials...
