Problems solved by technology

Among them, the template method can obtain nanometer-sized flow pores, but the template itself has a long manufacturing cycle, is expensive, and can only be used once, so this preparation method is difficult to promote
However, the dealloying method is difficult to obtain a flow pore size below 1 micron in actual production.

Embodiment 1

[0038] First, the surface of spherical calcium carbonate particles 1 with a diameter of 6 μm is dip-coated with a thin layer of water-soluble dilute binder, and when the surface of the binder starts to feel sticky, pour the calcium carbonate particles 1 into the cavity of the steel mold , the length of the cavity is 150mm, the width is 100mm, and the depth is 50mm. Cover the mold cover, operate the pressing device on the mold cover, and apply a pressure of 0.6MPa to make the adjacent calcium carbonate particles in the mold squeeze each other slightly to form an average diameter The contact area is 2 μm.

[0039] Next, the mold was put into a heating furnace to heat up, and the temperature in the furnace was controlled at 80° C. After heating for 20 minutes, the mold cover was opened. At this moment, the binding agent is completely dry, and the spherical particles 1 have been adhered to each other to become a cuboid, which is taken out, such as figure 1 shown. The binder make...

Embodiment 2

[0043] First, dip-coat a thin layer of water-soluble dilute binder on the surface of spherical aluminum particles with a diameter of 500nm. When the surface of the binder starts to feel sticky, pour the aluminum particles into the cavity of the steel mold. The length of the cavity is 100mm, width 80mm, depth 1.5mm, cover the mold cover, operate the pressing device on the mold cover, apply a pressure of 0.2MPa, make the adjacent particles in the mold slightly contact with each other, and form a contact area with an average diameter of 100nm.

[0044] Next, the mold was put into a heating furnace to heat up, and the temperature in the furnace was controlled at 70° C. After heating for 10 minutes, the mold cover was opened. At this point, the binding agent is completely dry, and the spherical particles have mutually adhered to a thin cuboid (this thin cuboid and figure 1 Similar, the difference is that the height of the thin cuboid is reduced), take it out. The binder makes the ...

Embodiment 3

[0048] First, if Figure 6 As shown, apply a thin layer of dilute adhesive on a flat and smooth paraffin wax plate. When the adhesive no longer flows and its surface is dry, use another flat plate to gently press the upper surface of the adhesive. Use a thickness gauge to measure the thickness of the adhesive. When the thickness reaches 3 nanometers, stop pressing the plate. At this time, use a 30mm*50mm rectangular frame 8 made of paraffin to surround the adhesive, and the inside of the rectangular frame 8 forms a thin block of adhesive 7. At this time, spherical particles 1 with a diameter of 6 nm are embedded in the thin block of binder 7 and arranged in a single layer (with the aid of a high-power microscope, the particles are arranged). After the binder is completely dry, the paraffin wax plate and the rectangular frame 8 are melted away, leaving the bonded single-layer granule and the binder thin block 7, such as Figure 7 shown.

[0049] Then, the single-layer partic...

Abstract

The invention discloses a preparation method for a porous solid material with the micro nano-sized circulation pore diameter. The preparation method comprises the following steps that pressure is applied to spherical particles of which the surfaces are coated with binders so that the spherical particles can adhere to one another and be formed, meanwhile, the size of the contact areas between the particles is controlled, or the spherical particles are flat spread in binder thin blocks, then, the binder thin blocks with the spherical particles are inversely placed on a substrate and pressed, the size of the contact areas of the particles and the substrate is controlled, and particle bodies are obtained; then, a material used for a framework is deposited in gaps between the particles through a physical or chemical deposition method, and the framework is generated; and finally, the particles and the binders are removed through a dissolution or baking method, and the porous solid material with the micro nano-sized or nano-sized circulation pore diameter is obtained. The preparation method has the beneficial effects that porous solid materials of different materials can be prepared as required, and the circulation pore diameter of the porous solid material is micro-sized or nano-sized, so that the application range of the porous solid material is wide.

Description
