| titleOfInvention | Method for preparing polyamideimide fibrid |
| abstract | The invention provides a method for preparing a polyamideimide fibrid, characterized by comprising the following specific steps: step 1: reacting diamine monomer with trimellitic anhydride chloride in an aprotic polar solvent in the presence of a catalyst to obtain a polyamide acid polymer, and carrying out chemical cyclization dehydration on the polyamide acid polymer to obtain a polyamideimide polymer solution; step 2: diluting the polyamideimide polymer solution, adding the diluted polyamideimide polymer solution and precipitation solution to a precipitation machine, and mixing to obtain a polyamideimide fibrid suspension; and step 3: washing, filtering and drying the polyamideimide fibrid suspension to obtain a polyamideimide fibrid. The invention is characterized by simple process, the size and shape of the fibrid are easy to be controlled, and the fibrid can be directly used to prepare high performance paper. |
