Problems solved by technology

[0003] Nowadays, PVB sound-proof laminated glass is commonly used. The PVB film is directly placed between two glass substrates. When the external environment temperature changes sharply, the shrinkage of the PVB film and the glass substrate is inconsistent, and there is a gap between the PVB film and the glass substrate. The overall strength become lower, affecting the service life of PVB soundproof glass and other issues

Abstract

The invention discloses high-strength laminated glass containing polyvinyl butyral (PVB) and a preparation method of the high-strength laminated glass. The high-strength laminated glass comprises twoor more glass sheet base layers and polyester films, each glass sheet base layer is arranged on the outer surface of the corresponding polyester film, filling layers are arranged between two polyesterfilm layers, and the filling layers are filled with PVB glue liquid. The space between the two polyester film layers is filled with the PVB glue liquid, high-pressure forming is conducted, multilayercompositing of a PVB film and a glass substrate is avoided, the lamination degree between the PVB glue liquid and the polyester film layers is high, the shrinkage degrees of the PVB glue liquid and the polyester film layers are basically consistent, high stability is achieved so as to achieve long-term use, the transmittance and reflectivity of light can be maintained at different temperatures, and the high-strength laminated glass has good heat insulation and noise reduction effects, can be widely applied to energy saving and noise reduction of buildings and heat insulation and sound insulation of car windows, is convenient to use and popularize, and has significant economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a high-strength laminated glass containing PVB and a preparation method thereof. Background technique [0002] Doors and windows are the products of human beings to improve the comfort of the environment. With the tense energy situation and the further improvement of human comfort, the energy saving and consumption reduction of doors and windows and the overall strength of doors and windows are also increasingly on the agenda. The use of polyvinyl butyral (PVB) film as the interlayer of laminated glass can prevent the glass from splashing and peeling off when the glass is broken. PVB laminated glass has high safety performance and has been widely used in the fields of construction and automobiles. [0003] Nowadays, PVB sound-proof laminated glass is commonly used. The PVB film is directly placed between two glass substrates. When the external environment temperature...
