| titleOfInvention | A kind of preparation technology of insulating aramid paper material |
| abstract | The invention discloses a process for preparing insulating aramid paper material, which includes the following steps: firstly preparing aramid paper pulp, using low molecular weight aramid fiber polymerization solution to produce aramid chopped fibers, and using high molecular weight aramid fiber polymerization solution to produce aramid fiber Pulp, mix aramid chopped fiber and aramid pulp for uniform dispersion to make aramid paper pulp, and the aramid paper pulp made is surfed to remove water, and the aramid paper that is wet on the Internet is removed. Compounded together to make the final wet aramid paper, the wet aramid paper is placed in a dewatering device for water removal, the aramid paper after dewatering retains a very low water content, and an appropriate size of material is placed in the material In the prepared mold, the temperature is cooled, the aramid paper is placed at a very low temperature, and the aramid paper at a low temperature is slowly heated to 25°C-30°C, and finally an insulating aramid paper material is made. The preparation process of the fiber paper material is perfect, and it can be prepared into any material that needs to be formed, which is convenient for the processing of subsequent materials. |
