Accompanying drawing explanation
Super thick SGP laminated glass structural representation in Fig. 1 the present invention.
concrete embodiment
Below in conjunction with embodiment, the present invention is described in further detail, understands the present invention to help those skilled in the art.
A kind of super thick SGP laminated glass, the SGP film 3 comprising at least two pieces of super thick glass substrates (upper glass substrate 11 and lower glass substrate 12) and be folded between two pieces of super thick glass substrates, described SGP film and described two pieces of super thick glass substrates onesize, wherein the thickness of super thick glass substrate is 12mm, 15mm or 19mm, these are several is existing specifications, but does not get rid of the glass being greater than other thickness of 10mm.The thickness of SGP film is greater than 1.52mm (according to circumstances can select 3.04mm or 2.28mm etc.).Super thick SGP laminated glass structure can be single layer structure: super thick glass/SGP film/super thick glass.Also can be multilayered structure: super thick glass/SGP film/super thick glass/SGP film/,, ,/super thick glass.The wherein SGP film SGP ionic polymer intermediate coat of preferably selecting du pont company to produce, this SGP ionic polymer intermediate coat, its excellent performance, tear strength is 5 times of general PVB film, hardness be the 30-l00 of PVB film doubly.
Prepare described super thick SGP laminated glass, preparation technology is: glass loading → cleaning machine cleaning glass → conjunction sheet → roll-in → vacuumize → send in autoclave to vacuumize to fire → lower the temperature and come out of the stove.
Wherein:
One, roll-in optimum configurations:
1, compression roller heights: reduce 4-5mm according to laminated glass thickness and arrange, if production specification is 15mm+2.28mm+15mm, total thickness is the laminated glass of 32.28mm, and arranging compression roller heights is 28mm;
2, in-furnace temperature is arranged: (take production specification as 15mm+2.28mm+15mm glass be example)
| Stove one temperature | Stove two temperature | Stove three temperature | Stove four temperature | Walking speed | Glass tapping temperature |
