According to the sponge synthesized from bio-based isocyanate, the bio-based isocyanate is bio-based toluene diisocynate (TDI), and the sponge is prepared from the following raw materials in parts by weight: 100 parts of polyol, 1.45- 4.7 parts of water, 0-12 parts of dichloromethane, 0.3-1.5 parts of a silicone surfactant, 0.1-0.33 parts of an amine catalyst, 0.02-0.39 parts of stannous octoate and 39.89-61.84 parts of the bio-based TDI. The sponge is synthesized from bio-based toluene diisocynate and polyol, the bio-based toluene diisocynate is synthesized from bio-based toluene, nitric acid, hydrogen and carbon monoxide as raw materials, and the bio-based toluene diisocynate is used to replace traditional toxic petroleum-based isocyanate, so that the dependence of sponge production on petroleum can be reduced, and meanwhile, carbon emission and environmental pollution caused by use of petroleum are reduced.
