Example Embodiment

[0088] Example 1

[0089] A method for preparing a gas gel modification of a phlioside fire insulation plate, including the following steps:

[0090] 34 kg of industrial seven aqueous magnesium sulfate was added to 22 kg of water, and thoroughly stirred and dissolved, and the magnesium sulfate solution was obtained. Gradually addition to 0.7kgeva rubber powder, 1.2kg citric acid, 10kg gas gel complex powder, mixed powder, high-speed dispersion of 60 min at 300-3000r / min through high speed dispersing machine, and achieve change Magnesium sulfate solution. Then, 19kg lightly magnesium oxide powder (lightly magnesium oxide content is not less than 80%), stirring is stirred at a thorough slurry, and the slurry is sent into the plate machine for template filling, double-sided After the alkali-resistant mesh cloth and the roller are gradually solidified to obtain a wet plate, the wet plate is cut, and the natural maintenance is obtained, that is, the thiragmic oxide sheet is obtained....

[0094] A method for preparing a gas gel modification of a phlioside fire insulation plate, including the following steps:

[0095]44 kg of industrial seven aqueous magnesium sulfate was added to 33 kg of water, and thoroughly stirred and dissolved, and the magnesium sulfate solution was obtained. In the mixed powder of 1.0kgeva rubber powder, 1.0kg citric acid, 15kg airgel composite powder, high-speed dispersion is 60 min, resulting in a high speed dispersion of 300-3000r / min, and is modified. Magnesium sulfate solution. Then add 38kg lightly magnesium oxide powder, stir well, form a homogeneous slurry, the slurry is fed into the plate machine, and the double-sided tolerate the alkalib fiber non-woven felt and the rolls, gradually solidify The wet plate, the wet plate is cut, and the natural maintenance is complete, that is, the thiragmic oxide plate, such as figure 2 As shown, Fig. A is a common thiraminated magnesium oxide plate, and Fig. B is a gas gel modi...

[0098] Example 3

[0099] A method for preparing a gas gel modification of a phlioside fire insulation plate, including the following steps:

[0100] 39kg industrial seven aqueous magnesium sulfate was added to 33 kg of water, and thoroughly stirred and dissolved, and the magnesium sulfate solution was obtained. Adding a mixed powder from 0.5 kGeva rubber powder, 1.0kg citric acid, 13kg gas gel composite powder, high-speed dispersion 60min by high-speed dispersing machine with a high speed of 300-3000r / min, and modified Magnesium sulfate solution. Then add 38kg of lightly magnesium oxide powder, stirred for 5 min, form a homogeneous slurry, the slurry is fed into the plate machine, and the double-sided to the alkali-resistant glass mesh cloth and the rolls are gradually solidified. The wet plate, the wet plate is cut, and the natural maintenance is obtained, that is, the thio-oxide sheet is obtained.

[0101] In this example, the gel composite powder is torn with a gas gel compo...

Abstract

The invention provides an aerogel modified magnesium oxysulfate fireproof insulation board and a preparation method thereof. The insulation board is composed of fiber-containing aerogel powder composite powder, magnesium sulfate heptahydrate, light calcined magnesia powder and an additive. The preparation method mainly comprises the following steps: S1, preparing a magnesium sulfate aqueous solution; s2, dispersing the magnesium sulfate solution, the aerogel composite powder, an additive and the like into slurry fluid through a high-speed dispersion machine; s3, doping light calcined magnesia powder and stirring evenly to form slurry, then pouring in a board making machine mold, and obtaining the magnesium oxysulfate fireproof insulation board through curing forming, cutting and curing. Compared with a traditional magnesium oxysulfate board, the fireproof insulation board has the advantages that the strength of the board is guaranteed, the density is lower, the heat insulation performance is better, the water resistance is obviously improved, and the comprehensive performance is obviously improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an airgel-modified magnesium oxysulfide fireproof insulation board and a preparation method thereof. Background technique [0002] Magnesium oxysulfide board is an air-hardening magnesium cementitious material product formed by activated magnesium oxide and magnesium sulfate solution. Compared with Portland cement board, magnesium oxysulfide board has relatively light texture, low thermal conductivity and excellent fire resistance It is widely used as a refractory insulating material, such as building wall panels, door core panels, ceiling panels, packaging boxes, etc., and can also be painted with blending paint and clear water paint according to needs, and can be processed into various types It can also be used for simple fire prevention projects in damp environments such as basements and mines. [0003] Compared with the commonly used magnesium oxychloride board, the magn...
