High-polymerization-degree high-temperature-resistant inorganic material and free radical polymerization method thereof
The invention relates to a high-polymerization-degree high-temperature-resistant inorganic material and a free radical polymerization method thereof, and the technical scheme is as follows: uniformly mixing iron oxide powder and (aluminum oxide powder, silicon dioxide powder and calcium oxide powder) according to the mass ratio of (0.1-4): 1 to prepare oxide mixed powder, filling the oxide mixed powder into a platinum crucible, and carrying out heat preservation for 2-3 hours to obtain the high-polymerization-degree high-temperature-resistant inorganic material. The preparation method comprises the following steps: adding polymeric monomer micro-powder into an active oxide melt containing free radicals, heating in a protective atmosphere until the polymeric monomer micro-powder is completely molten, keeping the temperature stable for 3-10 minutes in the protective atmosphere or an oxidizing atmosphere, adding the polymeric monomer micro-powder into the active oxide melt containing the free radicals according to the mass ratio of the polymeric monomer micro-powder to the active oxide melt being (0.1-1): 1, reacting for 5-30 minutes in the protective atmosphere, carrying out chain-type chain polymerization, and cooling to room temperature at the rate of 50-1000 DEG C/s, so as to obtain the polymeric monomer micro-powder/active oxide composite material. The high-polymerization-degree inorganic material is obtained. The preparation process is simple and short in period, the prepared high-temperature-resistant inorganic material is high in polymerization degree and has excellent high-temperature service performance, and the obdurability of the high-temperature ceramic material can be remarkably improved.
