| description | The invention relates to the technical field of solar back panel base membranes, and particularly discloses a preparation method of a melt straight-pulling weather-resistant solar back panel base membrane, which comprises the following steps: mixing dihydric alcohol or a dihydric alcohol mixture with dibasic acid or a dibasic acid mixture or with dibasic acid dimethyl ester or a dibasic acid dimethyl ester mixture to prepare slurry or a pre-melt; the preparation method comprises the following steps: preparing a raw material, adding a catalyst, carrying out an esterification reaction or an ester exchange reaction, carrying out pre-polycondensation and final polycondensation to obtain a melt, adding an anti-ultraviolet agent and an anti-hydrolysis agent into the melt, conveying the melt to a film drawing process, and carrying out sheet casting, longitudinal drawing, transverse drawing, heat setting, corona and cooling molding to obtain the ultraviolet-resistant film. According to the process, cooling, granulati |
