Boron-silicon-titanium hybrid resin-based high-temperature-resistant ceramic binder as well as preparation and application thereof
The invention relates to the field of high-temperature ceramic binding materials, in particular to a boron-silicon-titanium hybrid resin-based high-temperature-resistant ceramic binding agent as well as preparation and application thereof. The preparation method comprises the following steps: carrying out hydroxymethylation reaction on triphenyl borate and diphenyl borate to obtain boron hybridized phenolic resin, and carrying out condensation dealcoholization reaction on the boron hybridized phenolic resin and dialkoxy silane to prepare silicon hybridized boron phenolic resin; or carrying out alcohol exchange reaction with titanate to prepare the titanium hybrid boron phenolic resin. Then compounding with MQ silicon resin to obtain a polymer base material capable of cross-linking and curing reaction, further mixing with a metal oxide fluxing agent, adding high-temperature-resistant ceramic powder as a main material, taking a coupling agent as an interface treating agent and taking a solvent as an auxiliary material to obtain a viscous paste high-temperature-resistant ceramic binder, carrying out ceramic bonding, and carrying out normal-pressure sintering at 1500 DEG C to obtain the high-temperature-resistant ceramic binder. The binder forms a ceramic phase, and ceramic has good compression shear performance. The sintering temperature of the high-temperature ceramic can be effectively reduced, and the method has potential application in the field of aerospace materials.
