The invention provides a processing technology of laminated glass, the method comprises the following steps: preparing a first glass substrate and a second glass substrate, cutting, edging and cleaning for later use; preparing n PVB films, coating a layer of silicone rubber between each two PVB films, and then uniformly distributing an inorganic foaming agent on the silicone rubber to prepare a rubber-sandwiched layer; sequentially stacking the first glass substrate, the rubber-sandwiched layer and the second glass substrate and placing in a die of a press to obtain a semi-finished product under pressure; polishing the four edges of the semi-finished product, and polishing the rubber material with protruding edges after pressing to obtain the laminated glass. According to the processing technology of the laminated glass, the rubber-sandwiched layer is foamed by the foaming agent, so that a plurality of nano bubbles are arranged in the rubber-sandwiched layer, and the heat insulation and sound insulation performance of the laminated glass are improved.
