Abstract

The invention provides vacuum laminated glass, wherein the laminated glue material of the vacuum laminated glass is a modified EVA adhesive, and the modified EVA adhesive is prepared from the following raw materials: an EVA resin, a vinyl silicone resin, cis-polybutadiene rubber, butadiene styrene rubber, silicon dioxide, graphene, carbon fibers, a compatilizer, an antioxidant, a flame retardant,polyvinyl alcohol and sodium carboxymethyl cellulose. According to the principle of manufacturing the laminated vacuum glass, negative pressure vacuum is used for fully releasing volatile gas in the laminated glue, high-viscosity modified EVA glue is coated to rapidly bond vacuum glass and plate glass, and finally inflation and discharging are performed in an inner chamber; and the vacuum laminated glass has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a vacuum laminated glass. Background technique [0002] In order to improve the safety of glass, laminated glass formed by laminating glass is usually used. Since the existing laminated glass is far inferior to vacuum glass in terms of heat insulation and sound insulation, the best safety glass is vacuum laminated glass. The vacuum flat glass used in the new laminated vacuum flat glass for vehicles is made of ordinary float glass, which cannot be used directly due to its brittleness. Laminated vacuum flat glass (composite vacuum flat glass) is made through the lamination process to meet the requirements of the GBT 12482-1990 standard. In order to give full play to the superiority of materials and structures, in addition to understanding the physical and mechanical properties and production process of tempered glass and vacuum flat glass during production, it is also ne...
