Embodiment 1

[0040] Embodiment 1: A fireproof sealing material, each component and its corresponding parts by weight are shown in Table 1, and it is prepared through the following steps:

[0041] Step 1, firstly add Portland cement to the mixer, and then add sodium gluconate for premixing to obtain a premix;

[0042] Step 2, according to the order of perlite powder, gypsum powder, clay powder and premix, all the raw materials are added into the spiral mixer, and stirred and mixed evenly;

[0043] Step 3: After stirring with the spiral mixer for 15 minutes, unload the bottom material in the spiral mixer, return to the spiral mixer and continue stirring for 10 minutes, and then discharge the material to obtain a fireproof plugging material.

[0044] Among them, the fineness of clay powder is 200 mesh, the fineness of perlite powder is 80 mesh, and the grade of Portland cement is 325.

Embodiment 2-5

[0045] Embodiment 2-5: A fireproof sealing material, the difference from Embodiment 1 is that each component and its corresponding parts by weight are shown in Table 1.

[0046] Each component and parts by weight thereof in table 1 embodiment 1-5

[0047]

Embodiment 6

[0048] Embodiment 6: A fireproof sealing material, the difference from Example 1 is that the fireproof sealing material also includes 1 part of mesoporous silica, and ammonium polyphosphate is loaded in the pores of the mesoporous silica;

[0049] The steps of loading ammonium polyphosphate on mesoporous silica are: add mesoporous silica to deionized water to form a suspension, then add ammonium polyphosphate to the suspension to disperse evenly, and the weight ratio of ammonium polyphosphate to silicon dioxide is 0.1:1, the micropore diameter of mesoporous silica is 40nm, the particle diameter of ammonium polyphosphate is 10nm, and then it is ultrasonically treated for 10min, filtered and dried.

[0050] Among them, step 2 specifically includes adding all the raw materials into the screw mixer in the order of perlite powder, gypsum powder, clay powder and premix, and then adding mesoporous silica loaded with ammonium polyphosphate, stirring and mixing evenly .

Abstract

The invention discloses a fireproof plugging material and a preparation method thereof, relates to the field of plugging materials, and solves the problems in the prior art that the plugging material has too high compressive strength after solidification and is difficult to disassemble and assemble later. The fireproof sealing material includes the following components in parts by weight: 30-50 parts of gypsum powder; 15-25 parts of clay powder; 15-25 parts of Portland cement; 5-10 parts of perlite powder; 0.1-0.5 parts of sodium gluconate share. In the present invention, by adjusting the proportion of components and adding perlite powder and sodium gluconate, the specific gravity of the product is effectively reduced, which can be applied to light partition walls or through load-bearing boards, and the applicability of the product is improved; the curing speed of the product and the post-curing resistance The compressive strength index data is also more reasonable, which improves the convenience of replacement and removal.

Description

technical field [0001] The invention relates to the field of plugging materials, more specifically, it relates to a fireproof plugging material and a preparation method thereof. Background technique [0002] Fireproof sealing material is a kind of fireproof separation for sealing various openings and cable bridges formed when various penetrations such as cables, air pipes, oil pipes, air pipes, etc. , a material that has a fireproof function and is easy to replace. According to its composition and performance characteristics, it can be divided into inorganic fire blocking material, organic fire blocking material and fire retardant bag. [0003] Common plugging materials in the prior art include the following components in parts by weight: 30-60 parts of gypsum powder; 15-30 parts of clay powder; 15-30 parts of Portland cement. [0004] Due to the large specific gravity of the above-mentioned plugging material, it reaches 1.2×10 3 kg / m 3 , Lightweight partition walls or p...
