In order to further clarify the key properties of matrix resin in semiconducting shielding materials, three different types of semiconducting shielding materials at home and abroad were selected, and their microstructure characteristic, mechanical properties, electrical properties, and rheological properties were tested. The results show that the volume resistivity of each shielding material is low, and the temperature stability of resistivity is good. The acrylate content of the imported shielding material matrix resin is higher, polarity is greater, and the mechanical toughness is better. At the same time, the pseudoplasticity of the imported shielding material is stronger. In a certain shear rate range, the viscosity of the material can be reduced by increasing the shear rate appropriately, and the energy consumption can be reduced by increasing the fluidity, and then the production efficiency can be improved. Based on the results of the experimental analysis, the polarity or ester content of the material is proposed as a key parameter to reflect the matrix resin in the semiconductive shielding material.
