Definitions

  • the invention belongs to the technical field of ceramic materials, in particular to a low melting point porous ceramic material and a preparation method thereof.
  • Porous ceramic materials have the characteristics of large specific surface area, energy absorption, and damping.
  • the specially processed porous ceramics have selective permeability to liquids, gases and other substances, so they are widely used in various fields, such as automotive environmental protection, chemical industry, mechanical and biomedical fields.
  • commercial porous ceramics mainly use Al 2 O 3 , SiC, ZrO 2 and mullite as the main raw materials.
  • these materials have complex production processes, high sintering temperature, high energy consumption, high cost, or due to pore-forming agents.
  • the purpose of the present invention is to overcome the defects of the prior art and provide a low melting point porous ceramic material.
  • Another object of the present invention is to provide a method for preparing the above-mentioned low melting point porous ceramic material.
  • a low melting point porous ceramic material the firing temperature is 680-830 DEG C, the porosity is 24-42%, and the raw material is composed of a binder and raw material powder, wherein the raw material powder is mixed with the following mass percentages of raw material components After vitrification, wet grinding, drying and sieving to make:
  • the binder is dextrin.

  • the mass ratio of the raw material powder to the temporary binder is 80-90:10-20.
  • the mass ratio of the raw material powder to the temporary binder is 85:15.
  • the raw material powder can pass through a 5000 mesh screen.
  • the preparation method of the above-mentioned low melting point porous ceramic material comprises the following steps:
  • the first mixture is obtained by dry grinding and sieving in turn;
  • the temperature of the vitrification treatment is 800-900°C.
  • the heating rate in the step (7) is 4-6° C./min, and the holding time for sintering is 1.5-2.5 h.
  • the beneficial effects of the present invention are: the raw material components in the present invention act synergistically, and the obtained product has the advantages of simple sintering process, good mechanical strength, no need to add pore-forming agent and can generate pores, etc.
  • the problems of mismatched refractoriness, poor heat dissipation, and poor air permeability of the porogen can improve the life and holding force of the porous ceramic material.

  • the firing temperature of porous ceramics still needs to be 680 °C, and the firing temperature does not decrease with the increase of boron glass content.
  • the temporary binder used in the ceramic binder prepared by the present invention is dextrin, and the conventional temporary binder on the market, such as water glass, etc., will react with the ceramic binder during mixing or will generate pores after sintering. Destroying the pores of purple sand soil will make the ceramic bond denser.
