Continuous vacuum production method of laminated glass

Abstract

The invention provides a production method of laminated glass, which comprises the following steps that laminated glass enters a vacuum inlet chamber, is vacuumized to a first vacuum degree and is conveyed at a high speed; then enters a vacuum inlet buffer chamber, and is vacuumized to a second vacuum degree; then the material enters a vacuum inlet conveying chamber, the conveying speed is reducedto low-speed conveying, and vacuumizing is carried out to a third vacuum degree; then the material enters a vacuum heating chamber, a third vacuum degree is kept, and heating is carried out; then thematerial enters a vacuum cooling chamber, the third vacuum degree is kept, and cooling is carried out; then the material enters a vacuum outlet conveying chamber, the third vacuum degree is kept, theconveying speed is increased and conveying is realized at a high speed; then the material enters a vacuum outlet buffer chamber, and the vacuum degree is reduced to a second vacuum degree; and then the laminated glass enters a vacuum outlet chamber, the vacuum degree is reduced to the first vacuum degree, and a laminated glass finished product is output. The laminated glass produced by the methodis high in yield and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of production methods of laminated glass, in particular to a continuous vacuum production method of laminated glass. Background technique [0002] The traditional laminated glass production line is divided into two separate parts. The first part is preheating and rolling: after cleaning and pre-processing, the laminated glass is heated to 120~150°C in the preheating furnace to make the film reach fusion. Temperature, after the glass and the film are in good contact, the air between the glass and the film is expelled through a roller press, and the glass is naturally cooled and stacked. Glass; the second part of high-temperature and high-pressure molding: place the edge-sealed laminated glass in a high-temperature autoclave, set the temperature at 120~150°C, the pressure at 1.2~1.5MPa, and the time for about 2 hours, so that the residual air is discharged, and the glass and film Bonded together to form trans...
