Embodiment 2

[0023] Embodiment 2: respectively by weight magnesia 30%: magnesium chloride solution 50%: modification 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

[0024] Embodiment 3: magnesia 60% by weight: magnesium chloride solution 17%: modification agent 0.5%: short fiber 1%: fly ash 5%, the rest add vitrified microbead particles, this example adopts lightweight materials The vitrified microbead particles can enhance the compressive resistance of the entire door leaf in the case of the above-mentioned beneficial effects, and are suitable for buildings that require hardness and strength.

Embodiment 4

[0025] Embodiment 4: be respectively magnesium oxide 35% by weight: magnesium chloride solution 40%: modification agent 0.5%: short fiber 1%: fly ash 5%, all the other add 3% ceramic mud ball, 3.5% glass microsphere, 3% wood sawdust, 3% slag, 3% expanded perlite particles, 3% fiber. This example not only has high fire resistance, but also has the characteristics of light weight, heat insulation, high strength and high hardness.

[0026] The magnesium chloride solution glassy degree is 22 °-29 ° among the above each embodiment.

[0027]In this program, when filling the inner space of the door leaf and the door frame, 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 foam stabilizer 0.1% additive, 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 one of ...

Abstract

The invention relates to a cast-in-situ fireproof material of a fireproof door and a manufacturing method of the fireproof door, in particular to a cast-in-situ inorganic gelled material of a fireproof door leaf and a fireproof door frame, comprising the following components by weight percent: 30-60 of magnesia; 17-50 of magnesium chloride solution; 0.5-3 of modifier; 0.1-1 of flock and 5-30 of fly ash, which are mixed to be a liquid inorganic gelled material. The invention has the advantages that the inorganic gelled material is manufactured by a cast-in-situ mode, and no adhesive or no prefabricated inner is needed, thereby the conditions of cracks, filling and uneven material mix in the prior art are avoided, and materials which can evaporate noxious gas after heating are completely cancelled; the inorganic gelled material containing a large amount of foam is filled in a framework, thereby the weight of the whole fireproof door is reduced, and the transportation and the installation efficiencies are greatly enhanced; the foam has good insulation effect, and the solidified foam in the fireproof material can further shrink after pressure processing so as to have complete filling, thereby enhancing the density of the fireproof door and greatly strengthening the fireproof performance.

Description

technical field [0001] The invention relates to a fireproof material for the construction industry, in particular to a cast-in-place inorganic gelling material for fireproof door leaves and frames. Background technique [0002] At present, the fire protection of fireproof doors and frames in the prior art is mainly changed in materials and structures, but all parts of the fireproof doors are made in a split type and then assembled into a complete door leaf and frame. The gaps or joints between the parts are easy to be broken in case of fire, thus reducing the fire prevention effect of the whole fire door. Moreover, many of them use solid objects to fill the gaps in the fire doors. This method is prone to problems such as dead corners that cannot be filled and uneven mixing of various mixed materials. When a fire occurs, the fire resistance of the cracks is much lower than that of other parts. Some fillers will produce harmful substances when heated, endangering human health...
