A foaming process using a carbon dioxide solution, comprising: adding a parison into a carbon dioxide solution for primary foaming, taking out, and performing secondary foaming to obtain a cellular product. A polar liquid system is used for foaming; compared with direct foaming by using a high-pressure gas, a high-foaming ratio and uniform cellular structure can be obtained more quickly, and even for a highly crystalline polymer, a good foaming effect is achieved. Controlling changes of temperature and pressure after carbon dioxide is introduced can first control the impact and penetration of carbon dioxide on the surface of the cross-linked material, and further increase of the pressure and temperature promotes increase of the solubility of carbon dioxide in the polar system, so as to promote saturation of carbon dioxide in the polymer more quickly, thereby promoting formation of a high-foaming ratio and uniform cellular structure in the subsequent heating and foaming process.
