本发明涉及种防剥离的聚丙烯金属化薄膜加工工艺，通过对聚丙烯薄膜的工作面依次进行电晕放电处理、热拉工艺处理和冷拉工艺处理，然后将聚丙烯薄膜被送入真空镀膜机中，通过真空镀膜机中的送丝机构将铝丝送入蒸发坩埚中，铝丝在蒸发坩埚中从铝熔液变为铝蒸气，镀膜室中对聚丙烯薄膜进行真空蒸镀作业制成原料膜，原料膜经过分切后即制成所述防剥离的聚丙烯金属化薄膜。所述聚丙烯薄膜工作面的粗糙度显著提高，聚丙烯薄膜的工作面与镀铝层之间的结合强度显著提高，降低镀铝层和聚丙烯薄膜发生分离的几率，从而有效地提高金属化薄膜电容器的使用寿命。 The invention relates to an anti-peeling polypropylene metallized film preparing process. A working face of a polypropylene film is sequentially subject to brush discharge treatment, hot-drawn process treatment and cold-drawn process treatment; then the polypropylene film is fed into a vacuum coating machine, aluminum wires are fed into an evaporation crucible through a wire feeding mechanism in the vacuum coating machine, and the aluminum wires become aluminum steam from an aluminum solution in the evaporation crucible; the polypropylene film is subject to vacuum evaporation operation in a coating chamber to prepare a raw material film; and the raw material film is slit to prepare an anti-peeling polypropylene metallized film. The roughness of the working fa
