[Abstract] The invention relates to a high-performance elastomer composite material for printing rubber rollers and a preparation method thereof. The present invention successfully solves the problem of low hardness, moderate Mooney, and low energy content in the preparation of an elastomer composite material for a printing blanket by using in situ-modified dispersion technology and dynamic micro-crosslinking technology. Hardness, high strength, high wear resistance, and high durability are other technical challenges. The characteristics of the composite material of the invention are as follows: in the process of extrusion winding, the process is stable and the effect is good, sagging and broken bar phenomenon do not occur; during vulcanization, the rubber roller does not sink phenomenon; after vulcanization, the performance of the rubber material is excellent - Low hardness, high strength, high wear resistance, good oil resistance, ink resistance, good hydrophilicity, and low price.
