Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. Trade names for PVB-films include KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol and EVERLAM.

This utility model relates to the field of laminated glass and discloses a colored laminated glass, comprising two glass bodies, two fixing plates, and two limiting plates. Limiting grooves are formed on the upper and lower sides near the middle of the two fixing plates, and placement grooves are formed at the upper and lower edges of the two fixing plates. A placement block is fixedly disposed at the middle position of one of the opposite sides of the two limiting plates, and limiting blocks are fixedly disposed at both ends of one of the opposite sides of the two limiting plates. A PVB film is disposed between the two glass bodies. Each glass body includes a hydrophobic film layer, with a glass layer disposed within the inner end of the hydrophobic film layer, and an explosion-proof film layer disposed within the inner end of the glass layer. The hydrophobic film layer is made of siloxane coating, and the explosion-proof film layer is made of polyvinyl butyral. In this utility model, the hydrophobic film layer on the surface of the glass body can effectively prevent moisture adhesion, and the explosion-proof film layer can enhance the impact resistance and explosion resistance of the glass.
