Abstract
The invention discloses a sandwich glass dry-process laminating method. The method comprises the following steps in sequence: washing glass substrates by a washing machine, then blowing the glass substrates to dry the glass substrates by a blowing machine; putting the glass substrates to be laminated into a laminating machine, lifting the upper glass substrate by a vacuum sucker, putting a PVB rubber sheet on the lower glass substrate, putting the upper glass substrate on the PVB rubber sheet, cutting off the excess PVB rubber sheet, performing laminating to obtain semi-finished sandwich glass; subjecting the semi-finished sandwich glass to two times of heating and two times of rolling moulding; transferring the moulded semi-finished sandwich glass to a high pressure kettle, maintaining a constant temperature of 125 to 150 DEG C and a constant pressure of 8 to 15 bar for 30 to 40 minutes so as to obtain the finished sandwich glass. The original laminating technology is improved so as to strengthen the adherence between the glass and the PVB rubber sheet and improve the transparency of glass at the same time.
Description
Technical field
The invention belongs to field of glass production technology, be specifically related to a kind of dry lamination method of laminated glass.
Background technology
Laminated glass, pressing from both sides between two blocks of glass exactly into one deck take polyvinyl butyral acetal as the PVB intermediate coat of main component.Even if glass is cracked, fragment also can be bonded on film, and broken glass surface still keeps neatly smooth.This just effectively prevent the generation that fall event was stabbed and penetrated to fragment, ensure that personnel safety.
America and Europe, most of building glass all adopts laminated glass, and this is not only in order to avoid injury accident, also because laminated glass has fabulous antidetonation invasive ability.Intermediate coat can resist the continuous attack of the lethal weapon such as hammer, firewood cutter, and can also resist bullet within the long duration penetrates, and its safety precaution degree is high.
Summary of the invention
The object of the invention is to, a kind of dry lamination method of laminated glass is provided, by the improvement to original doubling technique, glass and PVB cohesion of film more firm, improve the permeability of glass simultaneously.
The dry lamination method of laminated glass provided by the invention, it in turn includes the following steps:
(1) glass substrate is cleaned by developing machine, and by blowing device, substrate is dried up;
(2) putting into combinating machine by needing to close the substrate of sheet, picking up upper slice with vacuum pad, putting into PVB film, to put down slice, prescind unnecessary PVB film, carry out conjunction sheet, become work in-process laminated glass;
(3) work in-process laminated glass is carried out respectively twice heating and twice roll-forming;
(4) the work in-process laminated glass after shaping is sent into autoclave, keep 30-40min namely to obtain laminated glass finished product through the constant temperature of 125-150 DEG C, 8-15bar constant voltage.
The dry lamination method of laminated glass provided by the invention, its beneficial effect is: by the improvement to original doubling technique, glass and PVB cohesion of film more firm, improve the permeability of glass simultaneously.
Embodiment
Below in conjunction with an embodiment, the dry lamination method of laminated glass provided by the invention is described in detail.
Embodiment
The dry lamination method of the laminated glass of the present embodiment, it in turn includes the following steps:
(1) glass substrate is cleaned by developing machine, and by blowing device, substrate is dried up;
(2) putting into combinating machine by needing to close the substrate of sheet, picking up upper slice with vacuum pad, putting into PVB film, to put down slice, prescind unnecessary PVB film, carry out conjunction sheet, become work in-process laminated glass;
(3) work in-process laminated glass is carried out respectively twice heating and twice roll-forming;
(4) the work in-process laminated glass after shaping is sent into autoclave, keep 35min namely to obtain laminated glass finished product through the constant temperature of 140 DEG C, 10bar constant voltage.
Claims (1)
1. a dry lamination method for laminated glass, is characterized in that: it in turn includes the following steps:
1. glass substrate is cleaned by developing machine, and by blowing device, substrate is dried up;
