Abstract

A preparation method of a transparent matting polyester film is characterized in that 100-260 parts by weight of ethylene glycol ethyl ether is added into a reactor and heated up to 80-100 DEG C for stirring up; 5-20 parts of nano silicone oxide is added and heated up to 125-135 DEG C; then 30-60 parts of methyl metharcrylate, 10-40 parts of ethanediol, 20-40 parts of 2 - hydroxyethyl methacrylate and 50-80 parts of glycidyl methacrylate are added in sequence for uniformly stirring up and introduced with nitrogen, then 0.2-0.8 part of azobisisobutyronitrile is added; the reaction is carried out for 6-8 hours under 80-115 DEG C, so as to obtain a transparent matting acrylic resin; the transparent matting acrylic resin is mixed with solution to obtain acrylic acid transparent matting resin solution; finally, the obtained acrylic acid transparent matting resin solution is coated on polyester film via coating process, thus obtaining the transparent matting polyester film. The film is applicable in heat transfer field, optics, advertisement cartography field, etc.

Description

technical field [0001] The invention relates to a method for manufacturing a polyester film, in particular to a method for manufacturing a transparent matte polyester film. The prepared products are mainly used in thermal transfer printing, optics, advertising graphics and other fields. Background technique [0002] In the prior art, transparent matt polyester (for example: polycarbonate PC, polyethylene terephthalate PET, polynaphthyl PEN, etc.) films used in fields such as thermal transfer printing, optics, and advertising graphics, There are generally two manufacturing methods: (1) Coating a layer of acrylic transparent matt resin on the surface of the polyester film; this method is to directly add various matting materials to the transparent resin solution (external addition method) , after simple mixing and dispersion, the resin is coated on the surface of the polyester film; using this method, the delamination phenomenon of the separation of the matting material and t...
