The invention relates to the field of binder materials, in particular to a modified paper-plastic composite adhesive and a preparation method thereof. The modified paper-plastic composite adhesive comprises the following components in parts by weight: 40-60 parts of animal glue, 15-30 parts of maltose, 10-25 parts of superfine talcum powder, 0.1-0.5 part of glutamine transaminase, 0.1-0.5 part of collagenase, 30-40 parts of water and 0-5 parts of auxiliaries. According to the invention, the modified paper-plastic composite adhesive overcomes the defects of poor environmental protection property and high cost of chemical paper-plastic composite adhesive and the undesirable phenomena of glue failure and foaming of a plastic film on the surface of a paper-plastic folder caused by poor bonding effect of animal glue and the plastic film in the prior art; the crosslinking density in the adhesive is effectively improved, so that the viscosity of the animal glue can be greatly improved, and the modified animal glue c
