PVB interlayer sound insulation film glass processing technology

The invention discloses a PVB interlayer sound insulation film glass processing technology. The technology comprises the following steps: S1, inspecting the appearance and size of glass; S2, cleaningwith pure water at 35 to 42 DEG C; S3, carrying out hot air drying; S4, laminating in a clean room; S5, primary heating; S6, carrying out primary rolling pre-pressing; S7, carrying out secondary heating; S8, carrying out secondary rolling and pre-pressing; S9, inspecting the effect of the pre-pressed surface; S10, loading into an autoclave trolley; S11, finally forming in a high-pressure kettle; S12, inspecting the products one by one; S13, product packaging. The temperature and humidity of the laminating chamber are limited, the sound insulation effect of the sound insulation film is guaranteed, the bonding strength of the PVB film layer and the glass is better, and the product quality is improved; in the rolling pre-pressing process, secondary rolling pre-pressing is carried out, the furnace temperature is divid
