The invention provides a method for manufacturing laminated glass based on a hot-press molding process; during a process of hot-press molding of the laminated glass, glass after laminating is not put in a vacuum bag, but silica gel and other high-temperature-resistant sealing materials are smeared on side faces of the peripheries of two glass plates and an interlayer, so that the sealing materials initially fix the laminated glass for avoiding the glass plates shifting while sealing the interlayer; an aspirating hole is reserved at one position of an adhesive sheet at the middle, and after the interlayer is vacuumized, the reserved aspirating hole is plugged to ensure the vacuum environment of the interlayer. According to the method, a vacuum bag in the prior art is omitted, only cotton cloth, lint or other flexible materials are required to be laid between contact faces of the lower glass plate in a die and a grinding device, and the upper surface of the upper glass plate is not required to be laid with the flexible materials; the upper surfaces of the glass plates do not produce indentation in the hot-press molding process, and only a part contacted with the die is required to be polished during post processing, so that the workload is saved, the rate of finished products is improved, and thus the goods delivery time is shortened.
