Description

Laminated glass manufacturing apparatus and laminated glass manufacturing method using the same

The present invention relates to a laminated glass manufacturing apparatus and a method for manufacturing laminated glass using the same, and more particularly, the first high-pressure reaction chamber in which the initial laminated glass is heated and pressurized, and the second high pressure reaction chamber in which the pressurized cooling is sequentially performed. The present invention relates to a laminated glass manufacturing apparatus and a laminated glass manufacturing method using the same, by which the final laminated glass is manufactured while being processed to improve productivity and workability of the laminated glass.

In general, the laminated glass refers to a glass bonded by fusion bonding a transparent film of polyvinyl butyral (PVB) material between two or more sheets of glass and strong adhesion.

Such laminated glass is not easily broken due to its excellent absorbing power against external impact, and even if the plate glass is broken, it prevents the laminated film from scattering of the broken glass and prevents theft because the object is not easily penetrated. It replaces general tempered glass and is used for building materials, industrial and other purposes.

When manufacturing such laminated glass, a high pressure reaction chamber, also known as an autoclave, is used. The conventional high pressure reaction chamber 10 is stacked in order to process a large amount of products at once, as shown in FIG. It is placed on the tray 30 and placed in the pressure-resistant container 40, it is mounted, the lid is closed and heated in a sealed state to maintain a constant temperature and perform a pressurized operation.

However, since the heating is performed in a state where the products are stacked at one time, it takes a lot of time to reach the desired heating temperature over all of the products, and even in the case of pressurization operation, even pressure is transmitted over all of the laminated products. There is a problem that takes a lot of time. In addition, since the internal pressure and the internal temperature of the autoclave need to be lowered in order to take out the product after the heat and pressurizing treatment is performed, there is a problem in that the productivity is greatly lowered.

In the case of performing the heat pressurization and the cooling pressurization process in one chamber as described above, the first bonding process is performed by first receiving the initial laminated glass inside the chamber and then pressurizing the chamber while raising the internal temperature to a predetermined temperature. Then, the internal temperature of the chamber is lowered again and cooled to pressurize while cooling to perform the secondary bonding process.

However, in the case where the heating pressurization and cooling pressurization treatment processes are simultaneously performed in one chamber as described above, a considerable waiting time is required to lower the internal temperature of the chamber in a state where the temperature is raised to a certain temperature, thereby causing a problem in productivity of the final laminated glass. In this case, the energy consumption is increased to lower the temperature inside the chamber, leading to an increase in the manufacturing cost of the product.

The present invention was devised in view of the above-described circumstances, and an object of the present invention is to separately provide a chamber for performing a heat press action and a chamber for a cooling press action in the manufacture of laminated glass by heating pressurization and cooling pressurization, Improve the productivity and workability according to the production of laminated glass by allowing the laminated glass to pass through the first high pressure reaction chamber having a heating and pressing action and the second high pressure reaction chamber having a cooling and pressing action sequentially to produce a laminated glass.
