Chinese patent document CN101481480A discloses a waterproof, cold-resistant, temperature-resistant and flame-retardant polyvinyl chloride insulating material and its manufacturing method. According to this patent, excellent comprehensive properties such as waterproof, low-temperature embrittlement resistance, low-temperature impact resistance, high-temperature aging resistance, and flame-retardant can be obtained. PVC insulating material, however, the invention patent does not involve surface migration resistance
Small-molecule plasticizers such as DOP, DINP, DOA, DOS, TOTM, etc. can improve the low-temperature resistance of PVC insulation materials, but small-molecule plasticizers are easy to migrate, and too many small-molecule plasticizers will cause soft PVC material molecules If the migration is too large, it will precipitate out during long-term use, making the soft PVC material hard and reducing its performance
The selection of polyester plasticizer with larger molecular weight can greatly improve the molecular migration performance of the material, but the compatibility between polyester plasticizer and PVC resin is poor, which makes the processing performance and low temperature resistance of PVC material worse

Description

technical field [0001] The invention relates to a cold-resistant, temperature-resistant, flame-retardant and surface migration-resistant polyvinyl chloride insulating material. Background technique [0002] At present, the comprehensive performance of the commonly used power cable is relatively common, and the grade is low. Generally, it does not have the comprehensive performance of low temperature embrittlement resistance, low temperature impact resistance, high temperature aging resistance, flame retardancy and surface migration resistance. It is not suitable for It is used in electrical, electronic and communication products that require flame retardancy and surface migration resistance in low temperature environment or high temperature environment. Due to the lack of medium and high-end varieties, there is an urgent need for innovative varieties in the field of mid-to-high-end power cables that are non-toxic and environmentally friendly, low temperature resistant, high ...
