Embodiment 1
[0027] Examples 1-5 are specific implementations of a light-storing and light-emitting polyvinyl chloride extrusion composition of the present invention. Wherein embodiment 1 is the best embodiment. The titanate coupling agent used in Examples 1-5 is the titanate coupling agent KR-36S produced by Kenrich Petrochemicals, Inc. (Kenrich Petrochemicals, Inc.), the main component of which is coordination-type tetraisopropyl Bis(dilauryl phosphite) titanate. The light-storage luminescent material used in Examples 1-5 is 100-300 mesh rare earth long-acting aluminate light-storage luminescent powder.
