The invention discloses a modified bio-based rubber nano composite material as well as a preparation method and application thereof, and belongs to the technical field of chemical engineering. The modified bio-based rubber nano composite material is prepared by carrying out coupling reaction on modified bio-based itaconate raw rubber and nano white carbon black. The modified bio-based rubber nano composite material contains Si-Si bonds formed by bonding silane groups of modified bio-based itaconate raw rubber and silicon hydroxyl groups in nano white carbon black. A silane group structure is introduced to a side group of an itaconate crude rubber macromolecular chain in a grafting modification manner, and then silane groups and silicon hydroxyl groups in the nano white carbon black are bonded together through a dehydration reaction, so that the dispersity of the nano white carbon black in the bio-based itaconate rubber is improved, and the stability of the bio-based itaconate rubber is improved. The processing performance and the mechanical performance of the bio-based itaconate rubber are improved.
