NOVELTY - Thermostat ceramic material comprises 20-30 pts. wt. yttrium oxide-magnesium oxide composite ceramics/graphene, 60-80 pts. wt. nano-aluminium oxide, 10-15 pts. wt. polycaprolactone polyurethane acrylate, 10-15 pts. wt. pentaerythritol tetraacrylate, 1-1.5 pts. wt. photoinitiator, 5-10 pts. wt. auxiliary burning agent, 1-1.5 pts. wt. polymer dispersant BYK, 10-15 pts. wt. active diluent, and 20-30 pts. wt. inert diluent. USE - The thermostat ceramic material used in many products e.g. home appliances, motors, refrigeration or heating. ADVANTAGE - The thermostat ceramic material: has high density, excellent mechanical properties, and excellent microstructure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the thermostat ceramic material comprising mixing and ball milling yttrium oxide-magnesium oxide composite phase ceramics/graphene, nano-aluminium oxide, polycaprolactone-type polyurethane acrylate, pentaerythritol tetraacrylate, auxiliary burning agent, polymer dispersant BYK, active diluent, and inert diluent for 10-18 hours, obtain the slurry, mixing the photoinitiator and the slurry evenly, placing it in the trough of 3D printer, carrying out light-curing 3D printing treatment to obtain a blank body, first heating the blank body to 550-600°C, heat preserving for 2 hours, and cooling it to 250-300°C, heat preserving for 30-50 minutes, cooling down to room temperature with the furnace, heating to 450-500°C, heat preserving for 2-3 hours, cooling to room temperature with the furnace, heating to 800-880°C, heat preserving for 30-50 minutes, heating to 1630-1650°C, heat preserving for 2-4 hours, cooling to 750-800°C, heat preserving for 1-2 hours, and cooling to room temperature with the furnace.
