Abstract

The invention discloses a matte PETG polyester material and a preparation method thereof, and relates to the technical field of high polymer materials. The matte PETG polyester material is prepared from the following raw materials in parts by weight: 60 to 80 parts of PETG resin, 5 to 12 parts of modified silicon dioxide, 4 to 10 parts of a modified ethylene-methyl acrylate copolymer, 1 to 3 parts of polyethylene glycol 4000, 0.2 to 0.5 part of an antioxidant 1010, 0.1 to 0.3 part of an antioxidant 168, 0.3 to 0.8 part of calcium stearate and 0.2 to 0.6 part of an ultraviolet light absorber UV-531. The matte PETG polyester material is scientific in formula, and the performance of the material is improved through the synergistic effect of the modified silicon dioxide and the modified ethylene-methyl acrylate copolymer. The preparation process is controllable, parameters of steps of drying, mixing, extruding and the like are clear, and the product stability is good. The antioxidant, the ultraviolet light absorber and the like are added, so that the anti-aging and anti-ultraviolet functions are achieved, and the application prospect is wide.
