Description

Technical Field

[0001] This application relates to the field of safety glass technology, and more particularly to a scratch-resistant and heat-insulating laminated glass assembly. Background Technology

[0002] To improve the natural light inside buildings, large areas of safety glass are usually used. This not only reduces indoor lighting electricity consumption but also enhances the building's aesthetics. However, using glass brings another problem: sunlight can pass directly into the room through the glass, which can increase the temperature of the indoor air. In summer, because heat transfer through the glass is faster, air conditioners need to increase their power to maintain a low indoor temperature, which leads to increased electricity consumption. Summary of the Invention

[0003] The purpose of this application is to provide a scratch-resistant and heat-insulating laminated glass assembly that can be used over a large area and can suppress indoor cooling power consumption.

[0004] To achieve the above objectives, this application provides a scratch-resistant and heat-insulating laminated glass assembly: comprising two layers of tempered glass, with an acrylic sheet and a PC sheet disposed between the two layers of tempered glass, the acrylic sheet and the PC sheet being bonded together by an ionomerically modified interlayer film, the acrylic sheet being bonded to the tempered glass by the ionomerically modified interlayer film, and the PC sheet being bonded to the tempered glass by the ionomerically modified interlayer film, thus exhibiting excellent light transmittance and stability.

[0005] As a preferred embodiment, the two tempered glass layers are an inner tempered glass layer and an outer tempered glass layer. The inner tempered glass layer is suitable for facing indoors, and the outer tempered glass layer is suitable for facing outdoors. The inner tempered glass layer is fixedly connected to the acrylic sheet through the ionomerized interlayer film, and the outer tempered glass layer is fixedly connected to the PC sheet through the ionomerized interlayer film. Allowing the PC sheet to face outwards can reduce the heating rate of the acrylic sheet.

[0006] As a preferred embodiment, the inner and outer tempered glass layers are of the same thickness and can be distinguished by a label on the outer side or by the difference in the thickness of the layers.

[0007] As a preferred embodiment, the thickness of the acrylic sheet is less than or equal to the thickness of the inner and outer tempered glass layers. The acrylic sheet has high strength and toughness, and it is sufficient to provide a stable attachment for the tempered glass without needing to be too thick.

[0008] As a preferred option, the thickness of the PC sheet is less than that of the acrylic sheet. The PC sheet has high temperature resistance, is not easily deformed, and has good structural stability. As long as it can produce sufficient reflection of infrared rays, it does not need to be too thick.

[0009] As a preferred embodiment, the thickness of both the inner and outer tempered glass layers is within the range of 5 to 10 mm to ensure that the tempered glass has high strength.

[0010] As a preferred embodiment, the thickness of the acrylic sheet is in the range of 5 to 8 mm to ensure that the acrylic sheet has sufficient thickness to block heat conduction.

[0011] As a preferred embodiment, the thickness of the PC board is in the range of 2 to 5 mm to ensure that the PC board has sufficient interface spacing to reflect infrared rays.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By setting acrylic and PC plates between tempered glass, the efficiency of heat transfer is reduced by using the hindering effect of acrylic and PC plates and ionized interlayer film on heat conduction, as well as the reflection effect of PC plate on infrared rays, so that large-area glass has better heat insulation performance and effectively reduces the energy consumption of air conditioning in summer.

[0014] (2) By designing the orientation of the glass assembly, the acrylic sheet is located inside the PC sheet. After the PC sheet reduces infrared radiation, the acrylic sheet is heated by infrared radiation, which further reduces the heating rate and thus further reduces the heat conduction speed.

[0019] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0023] like Figure 1-3 The scratch-resistant and heat-insulating laminated glass assembly shown comprises two layers of tempered glass. Because tempered glass has a very high surface hardness and is not easily scratched at room temperature, it is located on the outermost layer of the entire glass assembly and is in direct contact with the air, subject to touch and impact. Between the two layers of tempered glass are an acrylic sheet 3 and a PC sheet 4, both made of organic polymer materials with high strength and light transmittance. The acrylic sheet 3 has good heat insulation properties, while the PC sheet 4 not only insulates heat but also blocks infrared rays to slow down indoor temperature rise. The space between the acrylic sheet 3 and the PC sheet 4... The acrylic sheet 3 and the PC sheet 4 are bonded together using an ionomer-bonded interlayer 5, which is the common interlayer adhesive in SGP laminated glass. The ionomer-bonded interlayer 5 has high adhesion and only requires a very thin layer to produce a reliable adhesion effect. It can also adhere to a variety of materials. Therefore, the acrylic sheet 3 and the PC sheet 4 can be bonded to the tempered glass through the ionomer-bonded interlayer 5. After bonding, the strong adhesion will keep the acrylic sheet 3, the PC sheet 4 and the two layers of tempered glass relatively stable, which is equivalent to a fixed connection and will not cause relative movement.

[0024] The two tempered glass layers are inner tempered glass 1 and outer tempered glass 2. Although they are made of the same material and have the same thickness, they can be distinguished by labels. When installing this glass assembly, the inner tempered glass 1 faces indoors and the outer tempered glass 2 faces outdoors. In order to achieve better heat insulation, the inner tempered glass 1 is fixedly connected to the acrylic plate 3 through an ionomer interlayer 5, and the outer tempered glass 2 is fixedly connected to the PC plate 4 through an ionomer interlayer 5. In this way, the infrared rays from the outside can be blocked by the PC plate 4 first, and the acrylic plate 3 located on the inside heats up more slowly, and the high temperature from the outside is conducted into the room at a lower speed.

[0025] The inner tempered glass 1 and the outer tempered glass 2 have the same thickness, both ranging from 5 to 10 mm. The thickness of the acrylic sheet 3 is less than or equal to the thickness of the inner tempered glass 1 and the outer tempered glass 2, typically ranging from 5 to 8 mm. The thickness of the PC sheet 4 is even less than the thickness of the acrylic sheet 3, typically ranging from 2 to 5 mm. The total thickness of the entire glass assembly typically does not exceed 25 mm.

[0026] Working principle: During installation, first determine the inner and outer sides of the glass assembly, with the outer tempered glass 2 facing outwards and the inner tempered glass 1 naturally facing inwards. Since infrared rays from the outside are blocked by the PC board 4 after passing through the outer tempered glass 2, the intensity of infrared rays received by the acrylic board 3 is reduced. Due to the reduced rate of heat radiation and the excellent heat insulation properties of the acrylic board 3 itself, combined with the heat-blocking effect of the three-layer ionomer interlayer film 5, this glass assembly can effectively reduce the rate of heat conduction from the outside to the inside. This glass assembly has excellent heat insulation properties. In summer, when the temperature difference between indoors and outdoors is large due to air conditioning, this glass can also effectively block the transfer of heat, thereby reducing the energy consumption of air conditioning.

[0027] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
