Disclosed is a method for preparing polyester/polyolefin composite hot melt glue used for a solar cell bus board, comprising the following steps: first performing esterification, polycondensation, and synthesis on 2,6-naphthalic acid, ethylene glycol, and a titanium catalyst in a certain ratio, so as to obtain polyester PNT with a weight-average molecular weight of 15000 to 20000, and then, performing melt blending on the polyester PNT and low-density polyethylene under the effect of a bulking agent to obtain the target product hot melt glue. A film prepared by the hot melt glue has high luminousness, and a good mechanical performance, heat resistance performance, and anti-yellowing performance, and is particularly applicable to a solar cell bus board. |
