Description
Technical field
The present invention relates to a kind of silicone sealant, particularly a kind of luminous energy that sunlight or source of artificial light produce and storage light-emitting silicone sealant that luminous energy can be slowly released of absorbing.
Technical background
Along with the transformation of people's aesthetic standards, how existing practicality has the product emerge in multitude of sight again, and noctilucent material is wherein all used in many products to some extent.Traditional noctilucent material is sulfide-based fluorescent material, as ZnS:Cu, Er, and CaSrS:Bi, CaS:Bi etc., this class material noctilucence time is short, and low lightness has been added radioelement for improving its luminosity and noctilucence time, certainly will cause human body harm and environmental pollution.Kai Fa steady persistence advanced luminescent material in recent years, as rare earth ion europium (Eu) activated aluminate type noctilucent material, this material is long time of persistence, by absorbing ultraviolet or visible light, after being transformed, luminous energy is stored in the lattice, energy slowly can be converted into luminous energy again and luminous, open up novel noctilucent material field.Typical noctilucence product has noctilucence glass, noctilucence glass Mosaic, noctilucence Glass Craft, Noctilucent ceramics, luminescent coating, noctilucence ceramic tile, luminous plastics, luminescent screen or the like on the market.For example well-known: the precious wound science and technology in Taiwan is developed the glassy product-PolyGlow noctilucence glass of innovation recently, has after enough illumination, continues emitting characteristics in the dark, can build the atmosphere of hazy and illusionary romance at night.Be a kind ofly can satisfy high-end decoration and the functional glass market requirement and performance Designers, the required super new glass material of architect's intention; The disclosed patent CN101066856 of China relates to a kind of luminous GRP floor tile, has solved that the raw materials used cost of existing noctilucence floor tile is higher, manufacturing process is than complexity and the relatively poor problem of material capability, and the practicality of this material is strengthened greatly; The glad noctilucence glass Mosaic that reaches the production of noctilucence Science and Technology Ltd. in Foshan, the mosaic that seems ordinary under available light has colors such as oyster, white, and after the enough illumination, dark is sentenced colors such as jaundice green, blue-greenish colour, sky blue.The noctilucence glass Mosaic is used for local-style dwelling houses and public building, not only can beautify U.S. decorations and live and Working environment, simultaneously its absorb behind luminous energy in the dark or night self luminous characteristics brought very big convenience for people's live and work, saved the energy.The low emergency lighting effect of the luminous of Noctilucent ceramics, noctilucence glass Mosaic, its meaning is not only just energy-conservation, and its distinctive light penetration power can guide people in case of emergency to withdraw in order in dense smoke, reduces chaotic.
Yet the adhering and sealing of materials such as noctilucence glass, noctilucence glass Mosaic, noctilucence Glass Craft, Noctilucent ceramics, noctilucence ceramic tile all needs to use seal gum.Traditional neutral silicone seal gum is a single-component, and self cure has excellent cementability, and is easy to use, is widely used in the adhering and sealing of aluminum alloy doors and windows, glass and glasswork, pottery, masonry and most of plastics.But owing to lack illumination effect, when adhering and sealing noctilucence product or non-noctilucence product, integral body attractive in appearance there is considerable influence,, requires further to improve especially to the influence of whole luminous effect.
The objective of the invention is in conjunction with the performance characteristics of neutral silicone seal gum and the utilisation technology of luminescent material, prepare and a kind ofly absorb the luminous energy that sunlight or source of artificial light produce, and slowly discharge the luminous storage light-emitting silicone sealant of luminous energy.
Summary of the invention
The present inventor inquires into repeatedly for achieving the above object, found that and in common neutral silicone seal gum, add colorful long-afterglow energy-accumulating luminous agent, photostabilizer and superfine alkali free glass fibre powder, has luminous effect, time of persistence is long, the use selectivity is good, the transparency is good, and has effectively improved the weathering resistance and the resistance to cracking of neutral silicone seal gum.Can with noctilucence product or the supporting uses of non-noctilucence product such as noctilucence glass, noctilucence glass Mosaic, noctilucence Glass Craft, Noctilucent ceramics, noctilucence ceramic tile, thereby finished the present invention.
