The invention provides a foaming composition, a foaming material prepared from the foaming composition, and products containing the foaming material. The foam composition, in terms of mass percentage, includes: propylene polymer 21-93.6%, polyethylene 5-35%, elastomer 0-20%, blowing agent 1-20%, nucleating agent 0.1-0.1% 1%, cross-linking auxiliary agent 0.1-5%, antioxidant 0.2-3%; wherein, the cross-linking auxiliary agent is selected from aniline and its derivatives, triazole and its derivatives, aniline and its derivatives and At least one of a combination of acrylate compounds, and a combination of triazole and its derivatives and acrylate compounds. The invention also provides a preparation method of the foam material. Said method can solve the problems of the existing co-rotating twin-screw side-feeding extrusion radiation cross-linking foaming process that the foaming agent is easy to decompose, the equipment requires high precision, and the foaming material odor and VOC exceeded the standard, etc. question. |
