example 1

[0027] The applicant, Shanghai Yaohua Pilkington Glass Co., Ltd. (abbreviated as "SYP"), used the secondary rolling process in the process of producing the "SGP laminated glass with metal perforated plate" of the "Oriental Art Center" project. In terms of technology, two pairs of pressure rollers are used, and the second pre-compression is used. The gap between the pressure rollers is controlled according to the total thickness of the glass -2mm. The process of the cleaning machine and water quality, the process of the lamination room and the environmental control are the same as the production of ordinary PVB laminated glass. Basically stay the same.

[0028] 1# furnace surface temperature

[0029] In the production process, according to the surface pattern of the laminated glass after the pre-pressing section, the above process control parameters can be partially adjusted. The final shaping of the product in the autoclave refers to the ordinary PVB laminated gl...

[0031] In the process of producing the special-shaped "SGP laminated glass with metal perforated plate" (trapezoid, triangle, etc.) of "Oriental Art Center", the vacuum process is adopted, and the silicon rubber vacuum ring or nylon vacuum bag is used as the seal in the process. material, which significantly improves the sealing degree of vacuum preloading, and ensures that the gas remaining between the interlayer film and the metal plate is vacuumed out.

[0032] The time, temperature and vacuum degree system of vacuum preloading:

[0033] 1. Heating process: The temperature is raised from room temperature to 125-130°C within 60 minutes; the vacuum degree is always controlled below 30 Torr.

[0034] 2. Holding temperature: 125-130°C; holding time: 45 minutes; vacuum degree controlled below 30 torr.

[0035] 3. Cooling process: Turn off the equipment, and the glass will naturally cool down to room temperature with the equipment.

[0036] The final shaping of the product in t...

Abstract

The invention provides metal sandwiched glass with intermediate film which comprises a glass plate, intermediate film having surface gluing material EVA or SGP, a metallic decorative thin panel, an intermediate film of organic gluing material EVA or SGP, and a glass plate. And the secondary rolling production process comprises glass cleaning, hot-air drying, sheet combining, first heating, first rolling precompression, second heating, second rolling precompression, quality inspection, final forming in autoclave, and packaging.

Description

technical field [0001] The invention relates to a novel laminated glass product produced by a rolling method or a vacuum method, and belongs to the technical field of building materials. Background technique [0002] As a kind of safety glass, laminated glass has gradually been familiarized and understood by people. Ordinary laminated glass is just to bond two or more pieces of glass together through an organic adhesive material (interlayer film), which plays the role of safety, sound insulation and ultraviolet filter. A commonly used organic adhesive material is a PVB (polyvinyl butyral) interlayer. [0003] PVB (polyvinyl butyral) interlayer film is the most commonly used organic adhesive material for ordinary laminated glass. It is widely used because of its relatively low cost, mature technology, stable product performance, high bonding strength, and long service life. Widely used in building curtain walls, guardrails, doors and windows and other fields. The compositi...
