Embodiment 1

[0040] The mass ratio of raw materials is: PETG resin (intrinsic viscosity 0.80dL g -1 , the molar ratio of CHDM / EG is 30 / 70) 100, benzophenone UV absorber UV 5310.45, pigment permanent yellow 0.005, antioxidant 2,5-ditertbutyl hydroquinone 0.2, anti-oxidant Oxygen agent Hostanos P-EPQ 0.1, ethylene bis stearic acid amide 0.4.

[0041] Preparation method: Put 10 parts of PETG resin and all ultraviolet light absorbers, pigments, antioxidants and lubricants in the formula of amorphous transparent PETG copolyester functional film into a high-speed mixer, and control the speed of the mixer below 500rpm Stir at low speed for 3 minutes and discharge to the twin-screw extruder; the strong shear of the material through the twin-screw extruder makes the additives in the formula evenly dispersed in the PETG resin matrix, and finally the functional masterbatch is obtained by the pelletizer. Among them, the granulation and molding control conditions of the twin-screw extruder are as foll...

Abstract

The invention discloses an amorphous transparent PETG (Polyethylene Terephthalate Glycol) copolyester functional thin film. The multi-functional transparent PETG thin film can efficiently shield ultraviolet ray, infrared ray, high-energy visible light-blue light and the like. Meanwhile, the invention also provides a preparation method of the amorphous transparent PETG copolyester functional thin film. The preparation method is convenient to operate, and the product has stable performance. The amorphous transparent PETG copolyester functional thin film is prepared from the following raw materials in parts by mass: 100 parts of PETG resin, 0.3-0.6 part of ultraviolet absorbent, 0.005-0.020 part of paint, 0.5-1.0 part of modified metal oxide, 0.1-0.3 part of antioxidant and 0.3-0.6 part of lubricant.

Description

technical field [0001] The invention relates to a transparent polyester film and a preparation method thereof, in particular to an amorphous transparent PETG copolyester functional film and a preparation method thereof. Background technique [0002] Thermoplastic polyester is a linear polymer prepared by polycondensation reaction of saturated dibasic acid and diol. According to different types of dibasic acid and diol, a variety of thermoplastic polyesters can be synthesized. The main varieties of commercialized thermoplastic polyesters are: terephthalic acid (PTA) and ethylene glycol (EG) condensation polymerization to produce polyethylene terephthalate (PET), terephthalic acid and propylene glycol condensation polymerization to produce polyethylene terephthalate (PET), Polypropylene terephthalate (PTT), terephthalic acid and 1,4-butanediol condensation polymerization to produce polybutylene terephthalate (PBT), terephthalic acid and 1,4-cyclohexane Condensation polymeriza...
