Description

Light-emitting concrete with the help of photo-light pigments processed in glass and plastic

The invention consists of producing concrete in which is processed luminescent glass pieces, consisting of a luminous pigment whose chemical composition can be SrA1204: Eu, Dy, or Sr4AL14025: Eu2 +, Dy3 + or Sr2MgSi207: Eu2 +, Dy3 + or CaAl204: Eu2 +, Nd3 + or Y2A1204: Eu2 +, Nd3 + but may also contain a sulfide composition, or be made from alkaline rare earth, or other metals such as calcium, strontium, barium, aluminum, magnesium, silicon dioxide, europium oxide, dysprosium, neodymium oxide, yttrium oxide, sulfur dioxide or any other light-emitting pigment capable of emitting visible light in the dark, after these light-emitting or luminescent pigments have been charged by day, artificial light or blacklight, these pigments are capable of returning light in in the dark, these luminous pigments also called glow 20 in the dark pigments can be processed in glass or plastic, dispersed, with a dosage of 10% luminescent pigments as described in lines 6 up to and including 15 by weight, or more or less than 10%, for example 1% to 99% of this luminous pigment or introduced or applied to the glass pieces also called frits or grid or plastic pieces also called granulate or masterbatch by means of a coating, varnish paint or glue layer or introduced or applied by means of heating or glue layer or paint, or coating of the glass on the surface of the concrete, this can be done, for example, by incorporating pigments into the luminating pigments to mix in boric glass or low fusion glass or to process on or in or on glass, this glass is or can be broken afterwards, for example by cooling plates glass 1036967 2 faster or grinding or breaking the glass into small glass pieces or, on the other hand, to make small pieces of glass, whether or not regular or irregular in shape, solid or hollow, or alternatively vary in shape and large, for example 3-5 mm, but also other sizes from 10 microns to 25 centimeters, these glass pieces can be made with various melting temperatures and with different expansion coefficients or, in other words, a different expansion at high temperatures, this frit or 10 grid or plastic masterbatch or plastic granulate can be used at various melting temperatures, for example melting or melting glass at + 800 C or + 1050 C at other temperatures of +10 degrees to +2000 degrees Celsius, these pieces of glass are also referred to as frits or grid and can be mangled or not, polished, matte or clear or further processed with glass colors or other reflective pigments or, on the other hand, these luminescent glass pieces or plastic pieces as described, can be dispersed, sprinkled, sprinkled or applied as a top or bottom layer in a mold or applied with a glue as top layer or inserted into or processed on concrete, or otherwise processed for example by a coa on concrete or in a manner not specified in or on concrete, these luminescent glass pieces made of various types of glass or these luminescent plastic pieces also referred to as masterbatches or granules can be made of plastic or plastic materials such as PP, PE, PS , PA, PC, PVC, PVB, PMMA or other plastic types or rubber types, or aluminum types or metal types or other types as possible materials serving as carriers of light-emitting pigments in concrete, through these plastic or glass pieces or other pieces such as described on page 1 in lines 1 to 35 in or on or in 3 concrete, for example sidewalk tiles, curbs, concrete slabs, or other concrete surface or objects, a concrete is obtained that has the property that the pieces of luminescent glass and give light to plastic or other materials in the dark, by applying the luminous plastic or glass pieces to the surface in or on concrete, or luminous adding glass pieces or plastic pieces to the surface of the concrete, this concrete becomes luminous in the dark at least the plastic or glass pieces, a working method to achieve this but other methods can also be the luminous glass pieces on the bottom of a mold to be sprinkled, sprayed, glued, glued or otherwise introduced into or into the production process after which concrete is injected or poured into the mold, and further processed in accordance with the normal production process, after which the treated side with glass or plastic pieces or light-emitting pigments combined with other materials that are luminous, they are ground or flattened or otherwise processed so that the luminating glass pieces or luminating plastic pieces come to the surface so that the glass pieces or plastic pieces can give light after being charged with daylight or artificial light, the luminating glass or plastic pieces processed in concrete also respond to blacklight, depending on 2 5 of the type of light-emitting pigment, these can be specified in the colors, white light, blue light, dark blue light, yellow green light light blue light, purple light red light orange light and other colors, so that an additional decorative light is obtained in the light. dark, by adding various luminous glass pieces in various colors, a concrete is also created whose glass pieces give light in the dark, with this invention a concrete is obtained that contains glass or plastic pieces that give light in the dark, this concrete can be 4 pavement tiles, curbs, quays, plates, trays, floors, thresholds, stairs, walls, decorative objects, planters, or holders of a parasol or lamps or other objects or other concrete products such as bricks, tiles, plates, pebbles, or pebble-like products, or other unspecified products made of concrete, in which luminous glass pieces or plastic pieces are incorporated into concrete kt.
