The invention relates to a modified polyvinyl alcohol copolymer cross-linked ceramic green body reinforcing agent. Vinyl acetate and acrylic acid are subjected to a free-radical polymerization reaction in the presence of an initiator and a chain transfer agent, part of ester bonds of the copolymer are hydrolyzed when an alkali is added for treatment, and then, the acrylic acid and vinyl acetate modified polyvinyl alcohol copolymer ceramic green body reinforcing agent is prepared. The copolymer cross-linked ceramic green body reinforcing agent disclosed by the invention has relatively good dispersity, and the viscosity of slurry cannot be improved by adding the reinforcing agent into a ceramic slurry system; and during the forming of green body slurry, the slurry is completely hydrolyzed into an acrylic acid and vinyl alcohol copolymer under alkaline conditions, and hydroxyl groups of the copolymer are subjected to hydrogen bonding with particles in a green body, so that internal particles of the green body are of a reticular structure, the green strength, dried strength and glazed strength of the green body are greatly improved. The strength of the ceramic green body is greatly improved while the original adhesiveness, dispersity and viscosity reducing property of polyvinyl alcohol are kept, so that the reinforcing agent has a broad application prospect.
