Abstract

The invention discloses moisture absorption prevention thermal-insulating interlayer glass and a preparation method thereof. The interlayer glass comprises two layers of glass and a thermal-insulating adhesive film, wherein the thermal-insulating adhesive film is arranged between the two layers of glass; the thermal-insulating adhesive film comprises a modified thermal-insulating adhesive, an antioxidant and barium sulfate; and the modified thermal-insulating adhesive is prepared from the following components: polyethylene, polyurethane resin, emulsified silicone oil, organic silicon epoxy resin, polyvinyl butyral, nanosilicon dioxide, thermal-insulating particles, cellulose ether, superfine zinc powder, isopropanol, a light stabilizer and butanediol dimethylacrylate. The preparation method comprises the following steps: mixing the modified thermal-insulating adhesive, the antioxidant and barium sulfate, and performing extrusion pelletizing so as to form an adhesive film; and clinging a first layer of glass, the adhesive film and a second layer of glass, performing heating and film melting under a vacuum condition, and discharging air to completely cling the two layers of glass together, thereby obtaining the moisture absorption prevention thermal-insulating interlayer glass. The interlayer glass disclosed by the invention has high properties of moisture prevention and thermal insulation, and function integration is achieved.

Description

technical field [0001] The invention belongs to the field of glass preparation, and in particular relates to a moisture-absorbing heat-insulating laminated glass and a preparation method thereof. Background technique [0002] Laminated glass is made of two or more pieces of glass with one or more layers of organic polymer intermediate film between them. A bonded composite glass product. Even if the glass is broken, the fragments will be stuck to the film, and the surface of the broken glass remains clean and smooth. This effectively prevents the occurrence of debris punctures and penetrating falling events, ensuring personal safety. As a kind of safety glass, when laminated glass is broken by impact, due to the bonding effect of the PVB film sandwiched between two pieces of ordinary glass, it will not produce sharp fragments to hurt people like ordinary glass after it is broken. At the same time, the sound insulation and sunlight control properties of its PVB interlayer f...
