Problems solved by technology

[0002] In modern society, rock wool boards are widely used as thermal insulation materials in construction, ships and other fields. At present, the fire resistance limit of rock wool in the market is generally about 1 hour. The board must have higher fire resistance requirements, and ordinary rock wool cannot meet one of the requirements. In order to meet the needs of modern technological development, a rock wool product with a higher fire resistance limit is needed as a high-performance refractory material to meet the needs of building layers. The demand for high-performance fire-proof sealing materials in the field of inter-structure

Embodiment 1

[0021] A fire-resistant rock wool board, the chemical composition of the rock wool board includes Fe 2 o 3 and Al 2 o 3 , Fe 2 o 3 The mass of the rock wool board accounts for 13% to 18% of the total mass of the rock wool board, Al 2 o 3 The mass of the rock wool board accounts for 12% to 15% of the total mass of the rock wool board. The chemical composition of the rock wool board also includes SiO 2 , CaO and MgO, among which SiO 2 The mass of CaO accounts for 30% to 45% of the total mass of the rock wool board, the mass of CaO accounts for 10% to 20% of the total mass of the rock wool board, and the mass of MgO accounts for 3% to 8% of the total mass of the rock wool board.

[0022] The acidity coefficient of the rock wool board is 2.5-3. The organic matter content of the rock wool board is 0.5-1.5%.

[0023] The components of the rock wool board include: basalt, dolomite, hematite, and bauxite, and the mass parts of each component are: 60-70 basalt, 10-20 dolomite...

Embodiment 2

[0025] The preparation method of the rock wool board described in Example 1: the components of the rock wool board include: basalt, dolomite, hematite, bauxite, and the mass parts of each component are: basalt 60-70, dolomite Stone 10-20, hematite 10-20, bauxite 5-10, the preparation steps of rock wool board are:

[0026] 1) Mix basalt, dolomite, hematite, and bauxite evenly in parts by mass, and then input the mixture into an electric furnace and melt it at a high temperature of 1500°C to 1800°C to form a molten slurry;

[0027] 2) The molten slurry flows out from the flow port of the furnace body, and is spun at high speed by a four-roller centrifuge to form rock wool fibers;

[0028] 3) Collect, solidify and shape rock wool fibers to make rock wool products.

Embodiment 3

[0030] Further optimization on the basis of the rock wool board described in Example 2.

[0031] Take 640kg of basalt, 100kg of dolomite, 80kg of bauxite, and 180kg of hematite. After mixing the above raw materials evenly, they are transported into an electric furnace through a conveyor belt and melted at a high temperature of 1500°C to form a melt. The molten body flows out through the flow port of the furnace body, and is spun into fibers under the centrifugal force of the four-roller centrifuge. The adhesive is evenly sprayed, and the cotton is spread by the flat cloth method, and the three-dimensional three-dimensional folding technology is adopted to solidify and form. The test result of the obtained rock wool board is:

Abstract

The invention discloses a fire-resistant rock wool board and a preparing method thereof. Fe2O3 accounts for 13% to 18% of the total mass of the rock wool board, and Al2O3 accounts for 12% to 15% of the total mass of the rock wool board. The method includes the steps that the rock wool board is prepared from, by mass, 60-70 parts of basalt, 10-20 parts of dolomite, 10-20 parts of hematite and 5-10 parts of bauxite, all the raw materials are mixed to be even and put into an electric furnace through an input belt and melted at the high temperature of 1,500 DEG C to 1,800 DEG C into slurry, fibers are formed through a four-roller centrifugal machine in a high-speed mode, the rock wool fibers are collected, solidified and formed, and the rock wool board is prepared. The fire resistance duration of the rock wool board is larger than or equal to 2.0 h, and the fire-resistant rock wool board can be widely used for building-interlayer-structure fire-resistant sealing.

Description
