TECHNICAL FIELD

[0001] The utility model relates to the field of toughened glass, especially to a hot bending toughened glass. BACKGROUND

[0002] The hot bending toughened glass is a kind of curved glass treated by specific process, it combines hot bending forming and toughening treatment two technologies, can make various complex curved shape, meet the demand of modern architecture and interior design to aesthetic and individuality, with its unique aesthetic, safety and extensive application field has been market's favour.

[0003] The hot bending toughened glass has the arc, when being subjected to external force, will appear stress concentration phenomenon, makes PVB film bending limited, and broken glass is extruded and easy to separate from PVB film, the utility model aims at providing a new hot bending toughened glass structure to solve the above technical problem. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of hot bending toughened glass to solve the problem mentioned in background art.

[0005] To achieve the above object, the utility model provides the following technical scheme: including glass layer, PVB film, photosensitive shadowless glue and steel wire, the glass layer is respectively arranged in PVB film two sides and is attached with PVB film, there is gap between adjacent PVB film, photosensitive shadowless glue is filled in gap, the steel wire is located in gap.

[0006] To optimize the above technical scheme, further measures are taken as follows: the PVB film is regular quadrilateral and the distance between adjacent PVB films is the same, to ensure that the PVB film can be evenly distributed between the glass plates, so that the width of the gap remains the same.

[0007] As a further improvement to the above technical solution: the steel wire surface is wrapped with viscose fiber, the viscose fiber is distributed along the length direction of the steel wire, and the combination of the steel wire and the photosensitive shadowless glue is improved by the viscose fiber.

[0008] As a further improvement to the technical solution: the end of the glass plate is formed with an inclined surface, which facilitates the pouring of photosensitive shadowless glue into the glass layer.

[0009] As an improvement to the foregoing technical solution: the viscose fibers on the steel wires in the gap are intertwined with each other, which aims to improve the combination of steel wires in different directions in the gap, so that the steel wires form a mesh structure and are combined with the glass layer.

[0010] From the above description of the structure of the utility model, compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a kind of hot bending toughened glass, and the glass layer is adhered by the cooperation of the independent PVB film with good bending flexibility and the light-sensitive shadowless glue with good bonding strength, which can avoid the stress concentration of toughened glass caused by the curvature, and the separation of broken glass and toughened glass, with practical significance and popularization value. BRIEF DESCRIPTION OF DRAWINGS

[0012] The drawings constituting a part of this application are used to provide further understanding of the utility model, and the illustrative embodiments of the utility model and their description are used to explain the utility model, and do not constitute undue limitation on the utility model. In the drawings:

[0013] Figure 1 It is a three-dimensional structure schematic view of the utility model;

[0014] Figure 2 It is a local section structure schematic view of the utility model;

[0015] In the figure: glass layer-1, bevel-101, PVB film-2, gap-201, light-sensitive shadowless glue-3, steel wire-4 DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0017] EMBODIMENT

[0018] Please refer to Figure 1 And Figure 2 The utility model provides a kind of hot bending toughened glass, including glass layer 1, PVB film 22, light-sensitive shadowless glue 33 and steel wire 44.

[0019] The end of the glass layer 1 is formed with a bevel 101, and the glass layer 1 is arranged on both sides of the PVB film 22 and adhered to the PVB film 22, and there is a gap 201201 between adjacent PVB films 22, and the PVB film 22 is a regular quadrilateral and the distance between adjacent PVB films 22 is the same.

[0020] The light-sensitive shadowless glue 33 is filled in the gap 201201, and the light-sensitive shadowless glue 33 refers to a kind of adhesive that can be cured after UV irradiation in prior art, which has high transparency and high bonding strength, and does not affect the light transmittance of toughened glass, which belongs to prior art content known to those skilled in the art, so the specific composition and working principle of light-sensitive shadowless glue 3 are not further explained.

[0021] The steel wire 44 is located in the gap 201201, the surface of the steel wire 44 is wrapped with viscose fibers, the viscose fibers are distributed along the length direction of the steel wire 44, and the viscose fibers on the steel wire 44 in the gap 201201 are intertwined with each other.

[0022] Working principle: The photosensitive shadowless glue 3 can infiltrate the viscose fibers surrounding the steel wire 4, and after curing, the photosensitive shadowless glue 3 cooperates with the PVB film 2 to tightly bond the two glass layers 1 together, so that the glass layers 1 have good bonding strength.

[0023] The PVB film 2 has flexibility and can be bent, and the hardness of the photosensitive shadowless glue 3 is high, so when the heat-bent tempered glass breaks, the photosensitive shadowless glue 3 can adhere the broken glass to avoid the broken glass from peeling off, and the PVB film 2 can drive the broken glass to bend and deform, thereby prolonging the time of external force acting on the tempered glass, thereby reducing the peak value of the acting force, and there is a gap 201 between the mutually independent PVB films 2, and the bending and deforming degree of the tempered glass after breaking is larger relative to the whole PVB film, which is helpful to further weaken the peak value of the acting force.

[0024] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
