The invention relates to a method for replicating a hologram in a photosensitive composite web. The method according to the invention preferably comprises providing a master element comprising a substrate body and at least one master hologram, applying a photosensitive composite web on a surface of the master element, exposing the master element to copy the at least one master hologram into the photosensitive composite web, and separating the exposed composite web from the master element. The method further includes temporarily applying an optical adhesive film between the photosensitive composite web and a surface of the master element. The optical adhesive film enables optical contact between the master element and the photosensitive composite web during exposure. In another aspect, the invention relates to a method of replicating a hologram in a photosensitive composite web using an input coupling element wherein an optical adhesive film is introduced between the composite web and the input coupling element.

The invention discloses a preparation method of a high-temperature-resistant fireproof cable, and relates to the technical field of cables, a fireproof inner layer is prepared from expanded graphite, hydroxyl-terminated polydimethylsiloxane, quartz powder, silicone oil, methyltriethoxysilane, gamma-aminopropyltriethoxysilane and dibutyltin dilaurate in parts by weight; the cable has the advantages that the expanded graphite can be expanded at high temperature to form a heat insulation layer, the content of the expanded graphite is low, the expanded graphite cannot damage the insulating material and the polyvinyl chloride sheath after expansion, temperature propagation can be effectively prevented, the fireproof capability of the cable is further enhanced, and the cable has good application prospects. The dibutyltin dilaurate can promote the reaction among the components, so that the performance of the fireproof inner layer is more stable, and silane materials such as hydroxyl-terminated polydimethylsiloxane, methyltriethoxysilane and gamma-aminopropyltriethoxysilane are utilized, so that the stability and durability of the fireproof inner layer can be improved.
