Description

High-performance flame-retardant self-cleaning daylighting panel material easy to melt and free of dripping and production process thereof
Technical Field
The invention belongs to the technical field of easily-fusible daylighting panels, and particularly relates to an easily-fusible non-dripping high-performance flame-retardant daylighting panel and a production process thereof.
Background
The daylighting panel is a light-transmitting sheet material used for replacing a light-transmitting material for a building ceiling, and is widely applied to house buildings such as industrial production workshops, storage warehouses, commercial buildings, airports, stadiums, village and town biological base buildings and the like. At present, most of daylighting panels are prepared from polycarbonate, glass fiber reinforced epoxy resin and other materials, and have the characteristics of light weight, light transmission, easiness in installation, attractiveness and the like. However, the prior daylighting plate material still has a plurality of defects: firstly, due to the characteristics of flammability and the like of the high polymer material, passive fire is likely to form under the condition of an external fire source, for example, the fire risks are caused when fireworks, cigarette ends fall off, electrical short circuit and the like occur; secondly, after a fire disaster happens, the daylighting panel does not have the fusible performance, so a large amount of toxic smog cannot be emitted in time, and a large amount of casualties are easy to cause. In order to solve the problems, the fusible daylighting panel is produced, for example, the utility model patent application with the application number of 201921223127.4 discloses a preparation method of a fusible fixed daylighting window, which is characterized in that a plurality of heat insulation blocks are arranged between an upper layer and a lower layer of fusible daylighting panel, and the upper layer and the lower layer of fusible daylighting panel and the heat insulation blocks are fixed on a circular arch steel skeleton through a plurality of self-tapping screws. However, the fusible daylighting panel technology is mainly monopolized by foreign enterprises, and is usually prepared from modified polyester materials, so that the material cost is high, and the fusible performance is not ideal (the fusible performance needs to be about 150 ℃ to start fusing). If the common low-melting-point polymer is used as a base material of the easily-fusible daylighting panel, the mechanical property of the daylighting panel is too low, the daylighting panel is easy to drip, and the like, so that the use requirement cannot be met. Meanwhile, the lighting board is usually located at a position which is difficult to be manually cleaned, such as the top of a building, and the like, and the lighting board is often polluted by water stain, dust and the like after being used for a certain time, so that the lighting performance, the attractiveness and the like are influenced. Therefore, a need exists in the market for a novel daylighting plate material which is easily melted and does not drip, and has certain self-cleaning performance and flame retardant performance.
Disclosure of Invention
The invention aims to overcome the defects of the existing daylighting panel, provides a high-performance flame-retardant self-cleaning daylighting panel material which is easy to melt and does not drip, and a production process thereof, and greatly improves the fire safety performance of the daylighting panel on the premise of meeting other performance requirements.
