Abstract

The invention discloses a production process of a PETG high-resistance high light film, and belongs to the field of film materials of high light mold pressing door sheets and production technologies. The production process comprises the steps of batching: PETG particles, a lubricating agent, a bulking agent, an ultraviolet absorbing agent and an antistatic agent are uniformly mixed to obtain a mixed material; extrusion: the mixed material is added in a single-screw extruder for melting extrusion; longitudinal stretching: three areas of preheating, stretching and shaping are divided; the temperature is 70-75 DEG C; an infrared heater is used for auxiliary heating; and the longitudinal stretching ratio is 1.2-1.8 times; transverse stretching: four areas of preheating, stretching, shaping and cooling are divided; the temperature is 80-85 DEG C; the transverse stretching ratio is 2.5-3.5 times; film coating; trimming and slitting; and packing. The production process is simple and easy to operate; and the produced PETG film is proper in thickness, excellent in gloss, high in surface tension and high in stretching strength, and the edge tearing and breaking phenomenon is not liable to generate.

Description

technical field [0001] The invention relates to the technical field of film material and process production of high-gloss molded door panels, in particular to a production process of PETG high-gloss resistance film. Background technique [0002] With people's increasingly higher requirements for quality of life and the gradual strengthening of environmental protection awareness, the emergence of PETG high-gloss panels, sheet film, high-end decorative film and other products has made up for the existing PVC, PP, PMMA, PC and other materials in the processing of products. And many defects in use, it is a truly green and environmentally friendly product. [0003] PETG high-gloss film has high brightness, excellent chemical resistance, and is not corroded by acids, alkalis, oils, etc. Good toughness, no whitening after cold bending. Abrasion, stain and moisture resistance. The gas penetration rate is very low, which effectively isolates formaldehyde, dioxin and other harmful ...
