Problems solved by technology

However, in the process of manufacturing aluminum silicate or rock wool core boards, severe dust pollution is unavoidable. The dust floating in the air pollutes the production environment and also causes physical harm to operators.
In addition, during the mixing process, the fluidity of the material is reduced due to the dragging effect of the aluminum silicate fiber, as a result, it is difficult to mix the material and it is prone to insufficient filling during pressing.
These obvious shortcomings of the prior art restrict the improvement of the performance level of fire doors, thus posing a safety hazard

Embodiment 1

[0017] This embodiment is a perlite fire door core board, which contains 73% of 50 mesh expanded perlite measured by weight percentage, 17% of powdery magnesium oxide and 10% of magnesium chloride solution. Add 18 grams of phosphoric acid in addition to the cubic meter, and press it into shape according to the following method after stirring evenly:

[0018] (1) cold pressing

[0019] Stir the material evenly and put it into the mold, press the press with a pressure of 35T for 5 minutes to press into a blank sheet with a thickness of mm;

[0020] (2) hot pressing

[0021] Dry-heat the cold-pressed slab to 82±2°C, apply 120T pressure with a press for 20 minutes, and form a 30mm-thick core board after hot-pressing.

Embodiment 2

[0023] Embodiment 2 has the same raw materials as Embodiment 1, only the weight percentage is different, and the core plate thickness is 60 mm. The concrete proportioning of embodiment 2 is that 70 mesh expanded perlite accounts for 67%, powdery magnesium oxide accounts for 23% and 10% magnesium chloride solution, every cubic meter of mixing with the above-mentioned materials adds 12 grams of phosphoric acid in addition, after stirring evenly, press The following methods are pressed into shape:

[0024] (1) cold pressing

[0025] Stir the material evenly and put it into the mold, press the press with a pressure of 40T for 10 minutes to form a blank sheet with a thickness of 48mm;

[0026] (2) hot pressing

[0027] Dry-heat the cold-pressed slab to 95±2°C, apply a pressure of 130T with a press for 35 minutes, and form a 45mm-thick core board after hot-pressing.

[0028] The key properties of the core plate made by the present invention are as follows:

[0029] Density 280~3...

Abstract

The invention discloses a fireproof door panel made of pearlite. The fireproof door panel comprises the following components in percentage by weight: 65 to 75 percent of granulated expanded perlite, 15 to 25 percent of a powdered magnesium oxide, and 10 percent of a magnesium oxide solution. 10 to 20 grams of phosphoric acid is added into and mixed with each cubic meter of materials; and the mixture is uniformly stirred and molded according to the following method comprising the steps of: uniformly stirring the materials, putting the mixture into a die, and applying 30 to 40 tons of pressure by a pressing machine for 3 to 10 minutes to prepare a blank; heating the cold-pressed blank to reach temperature of between 80 and 100 DEG C, and applying 110 to 130 tons of pressure by the pressing machine for 20 to 40 minutes to prepare the door panel. The expanded perlite serving as a main ingredient is a natural substance, and is nontoxic and non-radioactive; and when the expanded perlite is combusted, the smoke toxicity AQ1 is more than or equal to 100.0, so that the safety is high. The prepared door panel has stable physical property and high fire resistance, and the heat value of the door panel is only 0.1 MJ / kg. The fireproof door panel is light and is favorable for protecting an assorted door from being deformed.

Description

technical field [0001] The invention relates to a composite material, in particular to a fireproof composite material. The main component of the material is expanded perlite, and the finished core board is mainly used for making wooden fireproof doors. Background technique [0002] Contemporary residential buildings, office buildings, hospitals, schools, large shopping malls and other buildings are equipped with corresponding fire safety measures, and fire doors are the most basic fire prevention facilities. Most of the fire doors available in the market are wooden doors, and the core boards of the inner linings are generally made of aluminum silicate fiber or rock wool. Require. However, in the process of manufacturing aluminum silicate or rock wool core boards, severe dust pollution is unavoidable. The dust floating in the air pollutes the production environment and also causes physical harm to operators. In addition, during the mixing process, the fluidity of the materi...
