Problems solved by technology

For example, Chinese patent 201610632382.9 discloses that by adding biomass fuel during the sintering process, the biomass fuel in the green body is rapidly carbonized in a high-temperature anaerobic and airtight environment during the sintering process, leaving only a small amount of coke, and the volume of the biomass fuel is rapidly occupied. Shrunken and filled with gas generated by biomass carbonization, numerous pores visible to the naked eye can be formed in the green body, but the ceramics prepared by the above method generally have the problems of uneven distribution of pore size and low porosity

Abstract

The invention provides a preparation method of a silencing microporous artistic decorative ceramic tile, and belongs to the technical field of porous ceramic materials. The preparation method comprises the steps: mixing water, acrylamide, dimethylene acrylamide and a dispersing agent, and adjusting the pH value to obtain a premixed solution; mixing the premixed solution, ceramic powder and a forming additive to obtain mixed slurry; mixing the mixed slurry, an initiator and a foaming agent for polymerization reaction to obtain polymerization product slurry; sequentially carrying out injection molding, demolding and drying on the polymerization product slurry to obtain a green body; and carrying out glue discharging and sintering on the green body, and thus obtaining the silencing microporous artistic decorative ceramic tile. Data of the embodiment show that the average pore diameter of the prepared silencing microporous artistic decorative ceramic tile is 0.01-2.0 mm, the porosity is 60%, the breaking strength and compressive strength are 990 MPa, the fracture toughness is 5-6 MPa*m<3> / 2, the insulation breaking strength is 18 kV / mm, and the Rockwell hardness is 88 HRA.

Description

technical field [0001] The invention relates to the technical field of porous ceramic materials, in particular to a preparation method of sound-absorbing microporous artistic decorative tiles. Background technique [0002] Traditional microporous sound-absorbing materials are rough and unattractive and are usually used in interlayers. They are not safe, environmentally friendly, and pose a fire hazard. At present, the main preparation method of porous ceramics is to add a foaming agent to the raw materials. The foaming agent generates gas during the firing process. By changing the type, quantity and particle size of the foaming agent, the size and shape of the pores in the ceramics are controlled. For example, Chinese patent 201610632382.9 discloses that by adding biomass fuel during the sintering process, the biomass fuel in the green body is rapidly carbonized in a high-temperature anaerobic and airtight environment during the sintering process, leaving only a small amount...
