[0002] Basketball is a physical confrontation sport centered on the hands. The existing basketball commonly used by people is an inflatable sphere. The current basketball structure includes an inner liner, yarn wrapping, a middle tire, a skin and an air nozzle. The air nozzle is set on one side, and the pattern of the skin is mostly irregular polygons. However, the inner liner of common basketballs mostly focuses on sealing and elasticity, but ignores the flame retardancy of the inner liner. However, due to people's love for basketball, they will play basketball outdoors even on sunny days. In some areas, the temperature in summer can reach 35 to 40 degrees Celsius, and the surface temperature will be higher, which can make ordinary roadside tires and asphalt roads emit a strange smell.

At the same time, the basketball is prone to rolling during storage. Therefore, there is a probability that the basketball will roll near the heating source (such as a heater, etc.), which makes the basketball have a probability of spontaneous combustion when it is continuously heated.
