This invention discloses a high-temperature corrosion resistance testing device for processing polycarbonate film, belonging to the field of new material testing technology. It includes a testing chamber with a storage tank for storing corrosive liquid installed on its upper surface. A partition is fixed inside the testing chamber, and a motor is fixed inside the testing chamber below the partition. This high-temperature corrosion resistance testing device for processing polycarbonate film utilizes a movable frame and a shielding plate in its testing mechanism. The movable plate moves up and down, driving a lever to engage with an inclined block, achieving a 30° rotation of the shielding plate.
