Processing material for stirring paddle of chemical reaction kettle and preparation method of processing material

[0023] (1) Add 10 parts of polyvinyl chloride resin and 2 parts of ultrafine polytetrafluoroethylene powder to 20 parts of bisphenol A epoxy resin, heat up to 130-135 ° C at a heating rate of 5 ° C / min and mix for 30 min. Then lower the temperature to 100-105°C at a cooling rate of 5°C / min, add 5 parts of volcanic ash and 1 part of sepiolite fiber, and continue mixing at 100-105°C for 10 minutes to obtain material I;

[0024] (2) Add 5 parts of chlorinated polyvinyl chloride and 2 parts of toughening agent to 15 parts of saturated polyester resin, heat up to 125-130 °C at a heating rate of 5 °C / min and mix for 20 minutes, then add 3 parts of ceramic micropowder , 0.5 part of bistrifluoromethanesulfonimide and 0.5 part of nano rubber powder, and continue to mix at 125-130 ° C for 10 minutes to obtain material II;

[0025] (3) Add 1 part of asbestos powder and 1 part of polyglycerol ricinoleate to material I, after mixing fully, cool down to 0-5 °C at a cooling rate of 5 °C

Then lower the temperature to 100-105°C at a cooling rate of 5°C / min, add 5 parts of volcanic ash and 1 part of sepiolite fiber, and continue mixing at 100-105°C for 10 minutes to obtain material I;

[0030] (2) Add 5 parts of chlorinated polyvinyl chloride and 3 parts of toughening agent to 15 parts of saturated polyester resin, heat up to 125-130 ° C at a heating rate of 5 ° C / min and mix for 20 minutes, then add 3 parts of ceramic powder , 0.5 parts of bistrifluoromethanesulfonimide and 0.5 parts of nano rubber powder, and continue to mix at 125-130 ° C for 10 minutes to obtain material II;

[0031] (3) Add 2 parts of asbestos powder and 1 part of polyglycerol ricinoleate to material I, after mixing fully, cool down to 0-5 °C at a cooling rate of 5

[0035] Utilize the processing material that embodiment 1 and embodiment 2 make to process into the stirring paddle of same size and structure, then install it in the chemical reaction kettle, and its performance is tested.

[0036]The test results show that the impeller can withstand corrosive chemical substances except strong acid and alkali, and can withstand high temperature of 200 ℃, and there will be no surface wear and deformation during the 3-year service life.
