The SGP connecting film 32 is used to reinforce the connection between the SGP interlayer film 3 and the PVB interlayer film 2, and the third adhesive 33 is used to reinforce the connection between the SGP interlayer film 3 and the PVB connecting film 22 and the SGP connecting film 32.

[0022] The working principle and use process of the utility model are as follows: during production, first, a protective film 11 and an adhesive film 21 are sequentially pasted on one side of the tempered glass body 1 and on the outer side of the PVB interlayer film 2, and then the PVB interlayer film 2 is installed between the two tempered glass bodies 1. After the PVB interlayer film 2 and the tempered glass body 1 are fixed, the SGP connecting film 32 is fixed to the bottom of the SGP interlayer film 3, and the SGP interlayer film 3 is wrapped on the outer side of the PVB interlayer film 2. When the SGP interlayer film 3 is wrapped on the outside of the PVB interlayer film 2, the first glue filling groove 111 and the second glue filling groove 31 are first filled with glue, and then the PVB connecting film 22 and the SGP connecting film are filled with glue.
