Abstract
The invention relates to the technical field of physical foaming, in particular to an environmentally friendly, efficient and low-cost method for preparing physical foaming materials. The method includes the following steps: place plates to be foamed in a reaction kettle, inject permeable medium for soaking treatment, saturate in the inert gas, and then foam at the high temperature condition; the temperature of the high temperature condition is not less than 80 DEG C. In the method for preparing physical foaming materials in the invention, the plates are treated with water and other permeable media, and the kettle foaming process is adopted to shorten the saturation time, thereby greatly improving the foaming efficiency and the performances of the foaming materials such as pore size homogeneity, pore distribution uniformity and foaming rate.
