Abstract
The invention relates to a PVC semiconductor material, which comprises the following raw materials: 40-60 parts of PVC, 30-40 parts of acetylene black, 10-20 parts of DOP, 5-10 parts of a plasticizer,1-3 parts of lead stearate, 1-3 parts of lead sulfate, 1-5 parts of lead phthalate, 1-3 parts of calciumstearate, 2-10 parts of a flame retardant and 1-2 parts of an antioxidant. The semiconductor material is prepared by the following steps: preparing raw materials, mixing, banburying, carrying out double-roller milling, cooling, drying, granulating by a granulator, screening, carrying out magnetic separation, metering and packaging in sequence. Acetylene black is added into the PVC formula of the cable material, so that the volume resistivity of the material can reach 103 omega.cm, and thecable material has semi-conductive performance and can be used for manufacturing various shielding devices, and the cost of raw materials is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of power cable materials, in particular to a PVC semiconductor material. Background technique [0002] Semiconductor materials are a class of electronic materials with semiconductor properties (conductivity between conductors and insulators, resistivity in the range of about 1mΩ·cm~1GΩ·cm), which can be used to make semiconductor devices and integrated circuits. In addition, various shielding devices also need to use semiconductor materials, and ordinary semiconductor materials are hard materials, which are affected by the processing performance of raw materials when making various shielding devices, and the cost is high. It is also very good. Therefore, the development of a PVC semiconductor material to prepare shielding products will greatly reduce the raw material cost and processing cost of the product. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a PVC semicond...
