The invention relates to a method for radiation curing of a pure organic silicone coated fabric by using electron beams. The method comprises the following steps of: dispersing vinyl silicone oil, dimethyl silicone oil, hydrogen-containing silicone oil, a silane coupling agent, trimethylolpropane triacrylate, nanoscale silica, a flatting agent and a surface active agent in a vacuum kneading machine, mixing evenly to obtain a coating, finishing a fabric with certain humidity by a rubber blanket preshrinking machine, hot pressing the fabric through a hot pressing roller of a mirror glazing calendar to obtain base cloth, evenly coating the coating on the base cloth, and placing the base cloth on a transmission beam rack of a low-energy electron accelerator through a transmission roller for radiation curing to obtain the fabric. The fabric produced by the method is silky and soft in hand feel, waterproof, anti-seepage, and good in breathability and moisture permeability, and can be widely used in clothing, outdoor, fashionable fabrics and the like; the clothing does not have wrinkles, is easy to iron, and has stretching and recovering properties, and outdoor textiles can withstand the invasion of sun, wind and water; and the coating provided by the invention does not contain any solvent, and is environment-friendly, safe, non-toxic, pollution-free, simple in preparation technology, convenient in operation and construction, and low in energy consumption.
