Abstract
The present invention discloses a PMMA modified thin film and a manufacture method thereof. The PMMA modified thin film comprises a main material, a lubricating agent, an antioxygen, a filler and a pigment, wherein the main material comprises 80-100 PHR PMMA, 0-10 PHR EVA, 0-10 PHR EMMA, 0-5 PHR ABS and 0-5 PHR-MBS; the lubricating agent accounts for 0.1-10% of the main material in weight; the antioxygen accounts for 0.1-10% of the main material in weight; the filler accounts for 0.05-0.5% of the main material in weight; and the pigment accounts for 0-10% of the main material in weight. The manufacture method comprises the steps: mixing the main material in a ratio; adding part of the antioxygen; placing in a kneading machine for low-temperature blending evenly; adding the lubricating agent, the rest antioxygen, the filler and the pigment; placing into the kneading machine again for low-temperature kneading evenly; enabling the kneaded material to pass through a 120-180 DEG C twin-screw extruder, a 120-180 DEG C open mill, a 160-200 DEG C four-roll calender, a 120-160 DEG C driving off wheel, and a 80-160 DEG C rear curtain for reeling; and cooling a reeled film by wind in a centralizing manner at 80 DEG C to form the PMMA modified thin film. The thin film can be drawn out in a calendaring manner by enhancing the toughness of PMMA materials and improving the notch sensitivity of the PMMA thin film.
