This invention provides a golf ball and a charging device for it. The golf ball includes a shell; a circuit module disposed within the shell, the circuit module including a battery and a component to be powered, the battery supplying power to the component; and a wireless receiving module disposed within the shell, the wireless receiving module including a receiving coil for receiving electrical energy from an external wireless charging pad, the wireless receiving module being electrically connected to the battery to transmit electrical energy to the battery. This invention solves the problem in the prior art where golf balls are difficult to wirelessly charge, thus hindering their reuse.

The application discloses an inlaid biodegradable polyurethane / lignin composite material and a preparation method and application thereof. The preparation method of the inlaid biodegradable polyurethane / lignin composite material comprises the following steps: (1) obtaining NCO-terminated polyurethane prepolymer by taking polycaprolactone, polycarbonate diol and polyisocyanate as raw materials; (2) mixing and stirring lignin with the NCO-terminated polyurethane prepolymer under a solvent-free condition; (3) adding glycerol or 1,4-butanediol into the system to perform a chain extension reaction, so as to obtain a chain-extended product; and (4) vulcanizing the chain-extended product to obtain the inlaid biodegradable polyurethane / lignin composite material. The application provides application of the composite material in preparation of an armored track shock-absorbing block. The polyurethane / lignin composite material prepared by the application has high strength, low compression permanent deformation and biodegradability and the like, and can improve the bearing capacity and durability of the armored track as a whole.
