Problems solved by technology

However, the above-mentioned technical solution adopts multiple mortar layers and inorganic slurry layers to be bonded together, which has a high bulk density and is inconvenient to use.
[0003] In summary, the composite fireproof panels obtained by the preparation methods disclosed in the prior art have poor environmental protection, low strength, and high bulk density, which limit their further application in wider fields

preparation example Construction

[0021] The invention provides a method for preparing a composite fireproof board, comprising the following steps:

[0022] a) Fix a number of stainless steel nails in the groove of the metal plate and apply an inorganic binder, then press into the ceramic fiber blanket folding block, so that the stainless steel nails penetrate the folding block; then coat the surface of the folding block with an inorganic adhesive, and then Bond the punching mesh and metal foil, hot press to the height of the inner frame of the metal plate groove, and obtain a composite fireproof board;

[0023] The compression rate of the ceramic fiber blanket folding block is 30%-60%.

[0024] In the present invention, several stainless steel nails are firstly fixed in metal plate grooves and coated with an inorganic adhesive. In the present invention, the plate material of the metal plate tank is preferably galvanized plate, stainless steel plate or aluminum plate, more preferably galvanized plate; its edg...

Embodiment 1

[0044] Weld the flat head of a stainless steel nail with a length of 9.5mm into the galvanized sheet groove (the edge forms an inner frame with a height of 10mm), and arrange the corresponding points of the mesh center of the punching net as fixed points at equal intervals, see figure 1 Process 2: Apply 136g of inorganic adhesive on the galvanized sheet tank and on the flat plate, with a thickness of 0.2mm, press into a 20mm thick standard ceramic fiber blanket folding block, so that the stainless steel nails penetrate the folding block, and then apply 523g of inorganic adhesive The bonding agent is applied on the surface of the folding block with a thickness of 0.8mm, see figure 1 Process 3; then bond the perforated net to the folded block to ensure that the stainless steel nails can pass through the perforated net, while the inorganic binder is extruded from the round hole and distributed on the surface of the perforated net, see figure 1 Process 4; then bond the aluminum fo...

Embodiment 2

[0046] Weld a section of the flat head of a stainless steel nail with a length of 19.5mm into the galvanized sheet groove (the edge forms an inner frame with a height of 20mm), and arrange the corresponding points of the mesh center of the punching net as fixed points at equal intervals, see figure 1 Process 2: Apply 136g of inorganic binder around the galvanized sheet tank and on the flat plate, with a thickness of 0.2mm, press into a 30mm thick zirconium-containing ceramic fiber blowing blanket folding block, so that the stainless steel nails penetrate the folding block, and then apply 523g of inorganic adhesive Adhesive is applied on the surface of the folded block with a thickness of 0.8mm, see figure 1 Process 3; then bond the perforated net to the folded block to ensure that the stainless steel nails can pass through the perforated net, while the inorganic binder is extruded from the round hole and distributed on the surface of the perforated net, see figure 1 Process 4;...

Abstract

The invention provides a composite fireproof plate and a preparation method thereof. The preparation method comprises the following steps that a), a plurality of stainless steel nails are fixed in a metal plate groove, are coated with an inorganic binding agent, and then are pressed into ceramic fiber blanket folding blocks, so that the stainless steel nails penetrate through the folding blocks; after the inorganic binding agent is coated on the surfaces of the folding blocks, a punching hole mesh and a metal foil are sequentially bound, hot pressing is carried out to the height of the frame in the metal plate groove to obtain the composite fireproof plate; and the compression rate of the ceramic fiber blanket folding blocks is 30%-60%. Compared with the prior art, the preparation method of the composite fireproof plate adopts specific process steps and conditions, and through pressing into the ceramic fiber blanket folding blocks, the obtained composite fireproof plate is excellent infire resistance and low in volume weight; meanwhile, the bearing capacity of the product is improved through the specific fixing mode under the action of the metal plate groove, the stainless steel nails and the punching hole mesh; and raw materials does not contain organic, toxic and harmful components, the environmental protection property is good, and wide application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of fireproof materials, more specifically, to a composite fireproof board and a preparation method thereof. Background technique [0002] The Chinese patent with the publication number CN109437681A discloses a composite fireproof board and its preparation method. A high-quality fireproof board is obtained by pressing different proportions of fireproof materials and skeleton reinforcement materials; its fire resistance grade reaches A1 , smoke toxicity reaches AQ1 level, and at the same time has good water resistance, acid and alkali resistance and freeze-thaw resistance. However, the above-mentioned technical solution uses a large amount of organic components, mainly adopts the chemical expansion method to prepare the composite fireproof board, and the raw material also contains chlorides, which will inevitably have an impact on safety and environmental protection, and the strength is not high. And the Chin...
