Description

Technical Field

[0001] The invention relates to the technical field of glass, and in particular to a fireproof glass and a preparation method thereof. Background Art

[0002] The existing hollow fireproof glass uses an aluminum alloy frame to isolate and support the two glass panels. However, the thermal conductivity of the aluminum alloy frame is high, which is not conducive to improving the energy efficiency of the building. In addition, the fire resistance of hollow glass is poor. Once the glass breaks at high temperature, it will lose its fireproof and heat-insulating functions. At the same time, due to the lack of support for the glass plate in the vacuum structure of the hollow glass, its wind pressure resistance is also weak. In addition, the existing fireproof glass panels with internal fireproof liquid do not have a vacuum cavity, and the heat insulation and sound insulation effects need to be improved.

[0005] Furthermore, a plurality of outer protrusions abutting against the outer glass plate are formed on the outer side surface of the fireproof heat insulation board, and a plurality of inner protrusions abutting against the inner glass plate are formed on the outer side surface of the fireproof heat insulation board.

[0006] Furthermore, the edge of the fireproof insulation board is provided with a T-shaped exhaust hole consisting of a horizontal hole and a vertical hole connected to the middle of the horizontal hole, and the two ends of the horizontal hole are respectively connected to the outer vacuum chamber and the inner vacuum chamber.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As shown in the figure, the warm-edge hollow fireproof glass of this embodiment includes an outer glass plate 1, an inner glass plate 2 and a transparent fireproof plate 3. The outer side edge of the transparent fireproof plate is formed with an outer insulation support rubber ring 4, the inner side edge of the transparent fireproof plate is formed with an inner insulation support rubber ring 5, the outer glass plate is bonded to the outer insulation support rubber ring, and the inner glass is bonded to the inner insulation support rubber ring; an outer vacuum cavity 6 is formed between the outer glass plate and the fireproof insulation plate, and an inner vacuum cavity 7 is formed between the inner glass plate and the fireproof insulation plate.

[0025] In a specific implementation, the outer heat-insulating support rubber ring 4 and the inner heat-insulating support rubber ring 5 are made of TPS material (thermoplastic elastomer). In the warm-edge hollow fireproof glass of this embodiment, the outer heat-insulating support rubber ring and the inner heat-insulating support rubber ring are used to replace the aluminum alloy frame for supporting and isolating the existing hollow glass. The heat transfer coefficient of the outer heat-insulating support rubber ring and the inner heat-insulating support rubber ring is small, which can greatly improve the heat insulation performance of the hollow glass.

[0026] The warm edge hollow fireproof glass in this embodiment has excellent heat insulation and sound insulation functions due to its vacuum cavity.

[0027] In the warm-edge fireproof glass and the preparation method thereof in this embodiment, a transparent fireproof board is arranged inside. The transparent fireproof board can be a PC board or a transparent fireproof plastic board disclosed in the invention patent with application number 2021113366637, thereby significantly enhancing the fireproof and heat-insulating properties of the hollow glass.

[0028] As an improvement to the above embodiment, a plurality of outer protrusions 8 are formed on the outer side of the fireproof heat insulation board, and a plurality of inner protrusions 9 are formed on the outer side of the fireproof heat insulation board, which are in contact with the inner glass board. The outer protrusions 8 and the inner protrusions 9 are integrally formed with the fireproof heat insulation board using the same material. When wind pressure acts on the outer glass board 1, the pressure borne by the outer glass board 1 can be transmitted to the transparent fireproof board 3 and the inner glass board 2 through the outer protrusions 8 and the inner protrusions 9, thereby providing support to the outer glass board 1, which can greatly improve the wind pressure resistance performance of the outer glass board 1.

[0029] As an improvement to the above embodiment, the edge of the fireproof heat insulation board is provided with a T-shaped exhaust hole 10 consisting of a horizontal hole 101 and a vertical hole 102 connected to the middle of the horizontal hole, and the two ends of the horizontal hole are respectively connected to the outer vacuum chamber and the inner vacuum chamber. The outer vacuum chamber 6 and the inner vacuum chamber 7 can be easily evacuated through the T-shaped exhaust hole 10, and the vertical hole 102 is blocked after evacuation to prevent air from returning to the vacuum cavity.

[0030] As an improvement to the above embodiment, an exhaust check valve 11 is provided in the vertical hole. The exhaust check valve 11 can better prevent the exhaust air from returning to the vacuum cavity.

[0031] The preparation method of the warm edge hollow fireproof glass in this embodiment comprises the following steps:

[0032] 1) A T-shaped exhaust hole 10 is processed on the edge of the fireproof and heat-insulating board 3.

[0033] 2) An outer heat-insulating support rubber ring 4 and an inner heat-insulating support rubber ring 5 are arranged on the outer side edge and the inner side edge of the fireproof and heat-insulating board 3 respectively.

[0034] 3) The outer glass plate 1 and the inner glass plate 2 are bonded to the outer insulation support rubber ring and the inner insulation support rubber ring respectively.

[0035] 4) The cavity between the outer glass plate and the fireproof insulation board and the cavity between the inner glass plate and the fireproof insulation board are evacuated through the T-shaped exhaust hole to form an outer vacuum cavity and an inner vacuum cavity, and then the T-shaped exhaust hole is sealed.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
