| description | The invention relates to a foaming material for automotive interiors and a production process of the foaming material, and belongs to the technical field of polyurethane foaming materials. The foaming material is prepared by foaming a white material and a black material, the white material comprises the following components in parts by weight: 1000 parts of polyether polyol, 130-170 parts of modified polyol, 25-35 parts of antibacterial filler, 8-20 parts of a catalyst, 0.7-5 parts of silicone oil, 80-95 parts of an opening agent and 15-26 parts of water, and the black material comprises the following components in parts by weight: 1150-1220 parts of diphenylmethane diisocyanate; the modified polyol with a branched hydroxyl structure participates in crosslinking to improve the crosslinking density, and the cyclotetrasiloxane structure serves as a supporting unit to improve the mechanical property and the recovery performance of a crosslinking network; the modified polyol is endowed with chelation through imin |
