Description

Technical Field

[0001] The utility model relates to an ultraviolet-proof door and window glass, belonging to the technical field of glass. Background Art

[0002] The sunroom is also called the glass room. It is a fully open, non-traditional building constructed with glass and metal frames to achieve the purpose of enjoying the sunshine and getting close to nature. With the continuous development of social economy and people's increasing requirements for living environment, sunrooms have gradually been built in more households. Of course, while enjoying the warm sunshine, the ultraviolet rays in the sunshine have become an important factor in people's skin diseases. Ordinary glass does not have the function of resisting ultraviolet rays at all, resulting in our bodies being completely exposed to the ultraviolet rays when we are close to the window indoors when the ultraviolet rays are strong, and we cannot fully enjoy the comfort brought by the sunroom.

[0003] Chinese document publication number CN202862710U discloses an anti-ultraviolet glass, which is suitable for use in ordinary doors and windows. If it is a sun room, it is necessary to consider the reaction of the glass after being smashed. This glass will break into pieces after being smashed and is not suitable for use in a sun room. Utility Model Content

[0004] The utility model aims to provide an ultraviolet-proof door and window glass to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is: an anti-ultraviolet door and window glass, comprising:

[0006] The pvb resin layer located in the middle layer;

[0007] A tempered glass layer is provided on the upper and lower sides of the PVB resin layer;

[0008] An anti-ultraviolet layer is provided on the outer side of the tempered glass layer;

[0009] A reflective film layer is provided on the outer side of the anti-ultraviolet layer;

[0010] The tempered glass layer and the PVB resin layer as well as the anti-ultraviolet layer and the tempered glass layer are connected by polyurethane adhesive.

[0011] Furthermore, a hydrophobic layer is provided on the outer side of the reflective film layer.

[0012] Optionally, the thickness of the hydrophobic layer is 20-30 nm.

[0013] Beneficial effects:

[0014] It has strong anti-ultraviolet ability. At the same time, when encountering external force, the PVB resin layer can prevent broken glass from scattering, making it suitable for use in sun rooms. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 3 It is a structural schematic diagram of a further embodiment of the utility model;

[0017] in:

[0018] 1-pvb resin layer;

[0019] 2-Tempered glass layer;

[0020] 3-UV protection layer;

[0021] 4-Reflective film layer;

[0022] 5- Hydrophobic layer. DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1 to Figure 2 , an anti-ultraviolet door and window glass, comprising a PVB resin layer 1 located in the middle layer, a tempered glass layer 2 is provided on the upper and lower sides of the PVB resin layer 1, an anti-ultraviolet layer 3 is provided on the outer side of the tempered glass layer 2, and a reflective film layer 4 is provided on the outer side of the anti-ultraviolet layer 3;

[0025] The tempered glass layer 2 and the PVB resin layer 1 as well as the anti-ultraviolet layer 3 and the tempered glass layer 2 are connected by polyurethane adhesive;

[0026] The anti-ultraviolet layer 2 is made of nano-indium tin oxide and nano-titanium dioxide mixed with a polymer resin (such as water-based polyurethane, epoxy resin or polyvinyl butyral), a coating additive, a diluent and a curing agent, which are coated on a transparent film substrate and heated and cured to obtain a transparent heat-insulating film, and then bonded and pressed to the outer side of the tempered glass layer 2 through polyurethane adhesive. The anti-ultraviolet glass has a strong anti-ultraviolet ability. At the same time, when it is hit by something or damaged by external force, the PVB resin layer can prevent broken glass from scattering, and is suitable for use in sun rooms.

[0027] Please refer to Figure 3Since the sun room is outdoors for a long time, there will be residual rainwater on the glass after it rains. In order to quickly repel water, a hydrophobic layer 5 with a thickness of 20-30nm is provided on the outer side of the reflective film layer 4.

[0028] The hydrophobic layer 5 is formed by medium-frequency magnetron sputtering of silicon dioxide and titanium dioxide on the reflective film layer 4 and then treated with a silane coupling agent.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
