Embodiment Construction

[0016] A PMMA modified film, including a main material composed of 80-100PHR PMMA, 0-10PHR EVA, 0-10PHR EMMA, 0-5PHRABS and 0-5PHR MBS; a lubricant with a weight of 0.1-10% of the main material; the main material 0.1-10% by weight of antioxidant; 0.05-0.5% of filler by weight of main material; and 0-10% of pigment by weight of main material. Its production method comprises the following steps:

[0017] A. Mix the main ingredients in proportion, add some antioxidants, put them in a kneader, and knead evenly at low temperature to obtain PMMA modified materials;

[0018] B. Add lubricant, residual antioxidant, filler and pigment to the PMMA modified material in proportion, and then put it into a kneader and knead evenly at low temperature;

[0019] C. Pass the kneaded material obtained in step B through a twin-screw extruder at 120-180°C, an open mill at 120-180°C, a four-roll calender at 160-200°C, and a pull-off wheel at 120-160°C. , 80-160 ° C post-coiling, roll film concent...

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.

Description

technical field [0001] The invention relates to the technical field of PMMA film and calendering thereof. Background technique [0002] PMMA has excellent light transmittance and weather resistance, but it is notch sensitive, and its strength and toughness are poor. If it is made into a thin film, it is easy to break. The existing processing of PMMA mainly includes extruded sheet and cast sheet. And make thinner, softer PMMA film domestically with the method for calendering and do not see relevant report yet. Contents of the invention [0003] The technical problem to be solved in the present invention is to solve the frangible and easy-folding problems after the PMMA material is made into a film, so as to be suitable for the method of rolling the film. [0004] The technical solution adopted to solve the above technical problems: a PMMA modified film, characterized in that it includes 80-100PHR PMMA, 0-10PHR EVA, 0-10PHR EMMA, 0-5PHR ABS and 0-5PHR MBS The main ingredi...
