Abstract
The disclosure relates to the technical field of new foaming materials, in particular to a preparation method of a microporous foam material with oriented cells, which comprises the following steps: (1) melting and mixing raw materials for preparing a polymer composite material, and then carrying out hot stretching to obtain polymer composite fibers; the raw materials comprise a polymer matrix, a fiber-forming phase substance and a processing aid; (2) arranging the polymer composite fibers prepared in the step (1) in the same direction, and performing hot pressing to obtain a polymer composite board with oriented fibers; and (3) carrying out supercritical fluid foaming on the polymer composite board prepared in the step (2) to obtain the microporous foam material with oriented cells.
