7. A method of making a high strength laminated glass comprising PVB, comprising the steps of: the method is characterized in that:
the method comprises the following steps that firstly, sheet combination operation is carried out, a glass sheet base layer (1) is placed in a sheet combination chamber, the glass sheet base layer (1) is laid on a workbench, butyl rubber is coated on the inner side of the glass sheet base layer (1), polyester film layers (2) are attached to the upper side and the lower side of the glass sheet base layer (1), a filling layer (3) is formed between the two glass sheet base layers (1), and a glue filling port is reserved on one side of the two glass sheet base layers (1);
secondly, performing glue filling operation, namely pressing the two glass sheet base layers (1) by using a press machine, slowly filling degassed PVB glue solution into the filling layer (2) between the two polyester film layers (2) by using a glue filling machine, and then standing;
step three, prepressing and exhausting, namely preheating the laminated glass subjected to glue pouring in the step two, then flatly prepressing and exhausting by using two rubber rollers, and sealing a glue pouring opening after finishing;
and step four, high-pressure forming, namely putting the laminated glass which is pre-pressed and exhausted into a high-pressure steam kettle, heating to 60-80 ℃, simultaneously heating and pressurizing, continuing heating to 100-1.2 Mpa at 150 ℃, starting heat preservation and pressure maintaining, carrying out high-temperature high-pressure forming, and then reducing to normal temperature and normal pressure to obtain the PVB laminated glass.
