Casting preparation method of electrically-deformed PVC (polyvinyl chloride) gel

The invention discloses a tape casting preparation method of electrically-deformed PVC (polyvinyl chloride) gel, which comprises the following steps: stirring dibutyl adipate and tetrahydrofuran until the dibutyl adipate and the tetrahydrofuran are fully mixed, keeping a stirring state, and adding PVC powder to obtain a mixture A; the stirring speed is adjusted, and the viscosity of the mixture A is controlled to be 900-1100 mPa.s; and starting a casting machine, preheating a casting channel, and carrying out casting film preparation by using the mixture A with the viscosity of 900-1100 mPa.s to obtain the PVCG film. The production efficiency, the yield and the consistency of the PVCG can be greatly improved, batch preparation of the electrodeformation films with the length magnitude of 10-100 m is achieved, and the time cost and the economic cost in the preparation process of the PVCG are greatly reduced. 本发明公开了一种电致变形PVC凝胶的流延制备方法，将己二酸二丁酯和四氢呋喃搅拌至充分混合，保持搅拌状态并加入PVC粉末，得到混合料A；调整搅拌转速，控制混合料A的粘度为900～1100mPa.s；开启流延机并
