Abstract The present invention discloses a modified plant protein adhesive which can be used in the paper coating composite. The described adhesive is not only low in does as compared with conventional plant protein adhesive, but also can make rheologic behaviour and other properties of paper coating composite be equal to that of conventional paper-coating composite. Its preparation method includes the following steps: preparing plant protein material and alkaline dispersion of polyacrylate, mixing the described polyacrylate and plant protein material to make them implement entanglement under the condition of certain temp. and time; and making them produce coprecipitation at the isoelectric point of the plant protein. The final plant protein material entangled with the polyacrylate, can be successfully used as plant protein adhesive of coated pigment, polymer latex and paper coating composite.
