Abstract

The invention discloses laminated hollow glass and a preparation method thereof. The laminated hollow glass comprises a first glass group, a hollow layer and a second glass group, which are sequentially bonded, wherein the first glass group comprises a glass base material, a PVB adhesive layer, a heat insulation layer, a PVB adhesive layer and a glass base material, which are sequentially bonded;the second glass group comprises a glass base material, a PVB adhesive layer, a sound insulation layer, a PVB adhesive layer and a glass base material, which are sequentially bonded. According to theinvention, the raw material composition is carefully selected, wherein the content of each raw material is optimized, and the sound insulation layer and the heat insulation layer in proper proportionare selected, so that the advantages of the raw materials are fully exerted, and the raw materials are mutually supplemented and promoted, and the prepared laminated hollow glass has excellent sound insulation and heat insulation properties; according to the preparation method of the laminated hollow glass, the laminated hollow glass is prepared through multi-section hot-pressing exhausting and heat and pressure preservation, and bubbles in laminated glass can be completely discharged.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a laminated insulating glass and a preparation method thereof. Background technique [0002] The promotion and use of laminated insulating glass is a sign of the progress of the times and the development of building energy conservation. Laminated insulating glass is composed of two or more pieces of glass. There is a certain interval between the glass and the glass. The interval is dry air, and the surrounding is wrapped with sealing material, so it is processed into laminated insulating glass. After the glass is broken, it will be glued together and will not fall. It is a safety glass with high safety. Therefore, laminated insulating glass is used in places with higher safety requirements, such as the front windshield of passenger cars, and places higher than 3 meters. The daylighting roof, bulletproof glass used in banks and aircraft is also a kind of laminated insula...
