Problems solved by technology

However, there are many types of raw materials used in this invention. The colorful long-lasting energy-storage luminescent agent used is an aluminate system energy-storage luminescent agent. Aluminate is used as a matrix, and rare earth ions are used as the main activator. In addition, phosphorus pentoxide is added. , magnesium oxide or boron trioxide as the afterglow enhancer also involves rare earth elements, and the cost is high; at the same time, the added luminescent agent has the disadvantages of poor compatibility with the substrate and poor insulation when applied to electric power. The salt system energy storage luminescent agent needs to be ground into a micron-sized powder and physically dispersed in the silicone sealant. The light scattering of the powder will reduce the transparency of the sealant

Abstract

The invention provides a transparent silicone sealant with a long lasting phosphorescence function, and a preparation method and an application thereof. The sealant is prepared from, by mass, 40-50 parts of 107 glue with the viscosity of 70000-90000 mPas, 5-15 parts of 107 glue with the viscosity of 450000-550000 mPas, 5-15 parts of fumed silica, 4-8 parts of a cross-linking agent, 0.3-1.2 parts of a silane coupling agent, 0.1-0.2 part of a catalyst, 2-8 parts of an organic long lasting phosphorescence agent and 20-40 parts of white oil. The preparation method is simple; the organic lasting phosphorescence agent adopted in the invention has low cost, and has good compatibility with colloid; and the sealant prepared by coordinating all the raw materials has the advantages of long lasting phosphorescence function, good transparency, good insulativity and good mechanical and adhesive properties, and is suitable for sealing outdoor buildings, electric power outdoor power transformation equipment and the like.

Description

technical field [0001] The invention relates to a transparent silicone sealant with long afterglow luminous function, a preparation method and application thereof, and belongs to the technical field of silicone rubber preparation. Background technique [0002] Traditional inorganic long-lasting luminescent materials (LPL) include four categories, namely sulfide long-lasting luminescent materials, aluminate long-lasting luminescent materials, silicate long-lasting luminescent materials, and rare earth long-lasting luminescent materials. However, this kind of LPL material based on inorganic system not only needs expensive rare elements, but also the preparation temperature is as high as 1000 ° C, and the energy consumption is high; in addition, many steps are required from the insoluble aluminate to the finished product, for example, the compound needs to be ground into a micron level The powder can be infiltrated into the solvent or matrix; the light scattering of the above p...
