Pore-forming agent for nanoscale porous ceramics as well as preparation method and application of pore-forming agent
The invention discloses a pore-forming agent for nanoscale porous ceramics as well as a preparation method and the application of the pore-forming agent. The pore-forming agent contains nanocrystal cellulose modified acrylic acid as the major component, and is mainly used for ceramic materials having Al2O3, SiC and SiO2 as the aggregate; the pore-forming agent for the nanoscale porous ceramics is prepared by use of the steps of four processes, namely acid hydrolysis, homogenization, freeze-drying and surface modification; the pore-forming agent and a ceramic matrix are mixed and fired to obtain the porous ceramics uniform in pore distribution and having the dimension reduced to the nanoscale; the preparation method of the pore-forming agent is simple; the pore-forming agent is a natural organic high polymer material, does not generate toxicity in the production and use processes, and conforms to the environmental protection requirement.
