Abstract: With paraffin wax and stearic acid as the matrix material, biomass base, glass powder and magnesium hydroxide as additives, the temperature-sensitive spheroids are prepared. The mechanical properties of the temperature-sensitive spheroids with different diameters, thicknesses and ratios were analyzed. The results show that the optimal diameter of the temperature-sensitive spheroid is 20.5 mm. The best thickness is 2 mm. The best materials ratio of paraffin, stearic acid, magnesium hydroxide, glass powder and biomass based is 4:1:2:2:1, at this moment, the maximum pressure the temperature-sensitive spheroid can withstand is 43.72 N.
