Luminous Pick ball

Belonging to the technical field of Pick ball preparation, the invention relates to a luminous Pick ball, which is prepared from the following raw materials: TPE and modified luminescent powder. The modified luminescent powder is obtained by adjusting the reaction pH of inorganic silicon modified luminescent powder and a silane coupling agent grafted fluorescent agent in a mixed solution of ethanol and water to a first reaction pH and reacting at a first reaction temperature for 2-8 hours; the silane coupling agent grafted fluorescent agent is prepared by gradually reacting cyanuric chloride, 7-hydroxy-4-methyl coumarin and an amino silane coupling agent in DMF (Dimethyl Formamide). The modified luminescent powder integrates the permanent luminescence property of the luminescent powder in a scene with poor light and the highlight characteristic of a fluorescent agent, and the possibility of no luminescence along with the use of a Pick ball is avoided, so that the problems mentioned in the background technolog
