Abstract

The invention relates to dry laminated glass production equipment and a method for producing laminated glass. The production equipment comprises a roller furnace, an exhaust pressure roller, an edge sealing compensation furnace and an edge sealing roller which are sequentially arranged; the roller furnace includes a roller furnace body and a roller heating pipe, and the roller heating pipe is a medium wave radiation pipe; the edge sealing compensation furnace includes a compensation furnace body and compensation heating pipes located in the compensation furnace body; the compensation heating pipes are shortwave radiation pipes. By the technical scheme, the problem about film suffocation is solved, production of the laminated glass by the roller pressing process is realized and is not affected by glass thickness and glass type, and defects of the vacuum pumping production is avoided.

Description

technical field [0001] The invention relates to the field of deep processing of laminated glass, in particular to a dry-process laminated glass production equipment and a production method of laminated glass. Background technique [0002] In the prior art, the common interlayer film of laminated glass is PVB or SGP film. Because the glass is heated by radiation in the rolling furnace, the temperature rise rate of the edge is faster than that of the middle part, which leads to the early bonding of the film at the tail. This bonding can be combined with Glass bonding may also be the bonding of two layers of film. After bonding, the air is sealed inside the laminated glass. Excessive air is difficult to penetrate into the film during the autoclave stage, eventually forming bubbles in the laminated glass. Especially for coated glass, because the film layer has a certain degree of absorption, the temperature of the glass rises rapidly, which makes the glass and the film stick tog...
