Description

Laminated glass, light-emitting unit and method for manufacturing laminated glass

The present invention relates to a laminated inlaid glass comprising a composite structure comprising a laminate layer of a first layer (A), a second layer (B) and an interlayer (C). Other aspects of the invention relate to a light unit comprising laminated glass and a method of making a laminated glass.

Laminated safety glass (including glass sheets and plastic sheets) is used in areas where safety integrity is highly desirable or requires structural integrity after fracture, but is particularly non-exclusively used in the field of architectural mosaic or automotive inlaid glass.

The surface may be used in this form for illumination or non-irradiation, where illumination may be produced by a suitable source. The entire surface can be illuminated, but a pattern can also be applied to the surface. Additionally, different light sources can be used to, for example, produce a colored or hindered luminescent effect. Such surfaces can be used, for example, in buildings, furniture, automobiles, trains, airplanes, and ships, as well as in facades, skylights, glass roofs, stair steps, glass bridges, ceilings, and railings.

US 2015/308659 A1 relates to a mosaic glass unit comprising a glass sheet and a plastic sheet laminated between the glass sheets and an illuminant, wherein the inlaid glass unit comprises at least three glass sheets and at least two alternating glass sheets. Plastic film between. The selection of at least three glass sheets combined with at least two intermediate plastic films allows for obtaining a three-dimensional image.

US 2013/0252001 A1 relates to a laminated mosaic glass for displaying information, comprising an assembly of at least two transparent inorganic glass sheets or sheets of strong organic material, which are sandwiched by thermoformable materials or by inclusion The interlayer foils of the interlayers are joined together, whereby the inlaid glass is characterized in that the illuminant is added to the interlayer by depositing a hydroxy terephthalate type illuminant material (in combination with an antioxidant additive) on the interlayer In the mezzanine. In addition, in US 2013/0252001 A1, a device for displaying an image on a transparent mosaic glass is disclosed, which comprises a laminated mosaic glass as previously mentioned and a source for generating laser-type concentrated UV radiation.

The document DE 10 2014 015 695 A1 describes a laminated mosaic glass having a polyvinyl butyral interlayer comprising an illuminant. The interlayer is obtained by extruding a polymer melt comprising an illuminant. Prior to extrusion, yttrium aluminum garnet (LuAG) and diluent and polymer were mixed.

WO 2007/023083 relates to a glass assembly comprising a phosphorescent luminescent material and two outer cover glass members, the outer cover glass members being indirectly or directly joined and the luminescent material being sandwiched therebetween.

Glass or light-emitting elements known from the prior art have the disadvantage that the production of light-emitting units in sandwich or laminated glass is relatively complicated and the resulting light-emitting unit is thus relatively expensive. When irradiated, a glass sheet larger than 50 cm in one direction usually exhibits uneven color and light intensity due to light absorption and a slight green color of the glass sheet. Further, when the laminated glass includes a glass sheet produced by a float glass process, undesired light scattering is observed in the laminated glass of the known light-emitting element.

The present invention provides an improved mosaic glass that can be used in a lighting unit and that allows distribution of light having a desired light color and light intensity distribution relative to one of the prior art objects.

Another object of the present invention is to provide an improved laminated inlaid glass that can be used in a lighting unit in which unwanted light scattering is avoided.

A laminated mosaic glass comprising a first layer (A), a functional interlayer (C) and a second layer (B) in sequence, wherein the functional interlayer (C) is sandwiched between the first layer (A) and the second layer (B) Between and in parallel with the first layer (A) and the second layer (B). Further, the functional interlayer (C) comprises at least one organic luminescent colorant uniformly distributed in the material forming the functional interlayer (C). The first layer (A) and the second layer (B) are optically transparent layers having an air side and a tin side, which are obtained by a floating glass process, and the air side and the second layer (B) of the first layer (A) The air side is configured such that it faces the functional interlayer (C).

Laminated mosaic glass can be prepared using a lamination process known in the art for making laminated safety glass. In particular, the functional interlayer (C) is preferably based on the layers typically used in laminating safety glass. The functional interlayer (C) comprises at least one luminescent colorant uniformly distributed in the material forming the functional interlayer (C). The provided laminated glass can be combined with a light source to form a light emitting unit. These lighting units can be used in buildings (such as buildings and furniture) or in the automotive or aerospace sector.

When used in a light unit, light can be coupled to a laminated mosaic glass from at least one edge. Preferably, the light is coupled to the laminated mosaic glass such that the light exhibits internal reflection, especially total internal reflection. Light is partially absorbed by the luminescent coating and re-reflected. The luminescent coating emits light at any angle, thereby allowing the light to be re-reflected away from the laminated inlaid glass. By using a luminescent coating, the light is intentionally scattered so that the re-reflected light does not exhibit total internal reflection.

The first layer (A) and the second layer (B) The material of the first layer (A) and the material of the second layer (B) are optically transparent layers obtained by a float glass process. In a floating glass process, the molten glass material floats on a bed of molten metal, usually tin. One side of the glass material facing the molten metal bed is referred to as the tin side and the opposite side is referred to as the air side. A small amount of metal diffuses into the glass material and forms an impurity that can scatter light. Tin impurities in the float glass can be easily detected by irradiating short wavelength (e.g., 254 nm) UV light onto the glass surface. The tin side glows under UV light, with the air side not.

It has been found that undesirable light scattering in the inlaid glass unit of the present invention is reduced by laminating the functional interlayer (C) to the air side of the first layer (A) and the air side of the second layer (B), respectively.

The first layer (A) and the second layer (B) are selected from glass materials. Advantageously, the glass material has a lower oxygen permeability than the polymeric material. Therefore, when glass is used as the material of the first layer (A) and the second layer (B), exposure of at least one organic luminescent colorant to oxygen can be prevented and the stability of the colorant can be improved.

Laminated laminated glass layers are laminated by any of the processes known in the art, for example by stacking laminated glass layers and by, for example, placing them in a vacuum bag under vacuum and in an autoclave, for example, at 100 Lamination is carried out at ° C to 180 ° C and, for example, at a pressure of 2 to 20 bar and/or, for example, baking for 0.5 to 10 hours. In particular, the formation includes a stack of the first layer (A), the functional interlayer (C), and the second layer (B) in sequence and subsequent lamination. For lamination, any air trapped inside the formed stack must be removed and the first layer (A) and the second layer (B) joined separately by application of heat and/or pressure by means of a functional interlayer.

To facilitate the removal of the trapped air, the functional interlayer (C) preferably has a surface defining the roughness. The rough surface of the functional interlayer (C) provides a passage that allows air to flow out of the formed stack and thereby facilitates degassing of the stack in the lamination process.

The surface roughness is measured by the average surface roughness depth Rz. Rz is preferably in the range of 10 μm to 80 μm. The surface roughness Rz is particularly preferably in the range of 20 μm to 60 μm. The average surface roughness Rz is defined in DIN EN ISO 4287:2010-07 as the average of the 5 individual roughness depths obtained from successive individual samples of the roughness feature. The roughness depth is given by the distance between the highest peak and the lowest valley of each sampled feature.

Preferably, the surface roughness of the functional interlayer (C) is irregular and does not form a regular pattern to avoid the corrugated pattern in the laminated glass. This random pattern can include a plurality of discrete unoriented micro-pits and protuberances.

Preferably, the functional surface is structured by selecting the extrusion speed such that the melt breaks and the patterned surface of the functional interlayer (C) is obtained.

Melt fracture occurs when the polymer exits the extruder at a rate above the critical speed. Extrusion of the same polymer at a rate below the critical speed will result in a smooth surface. For example, the critical speed can be determined by gradually increasing the rate at which the polymer exits the mold (by increasing the flow rate of the polymer through the extruder) and observing the surface of the extruded sheet.

Additionally or alternatively, the surface pattern on the interlayer can be obtained by embossing and extruding through a conventional die having a serrated lip. If embossing is used, the extruded functional interlayer can be embossed by means of a roll having a surface embossed pattern.
