The invention relates to the field of silicon-rubber composite materials, and particularly relates to a preparation method of a silicon-rubber composite molding material. The method adopts methylvinylsilicon rubber, fumed silica, precipitated silica, hydroxyl silicone oil, silane coupling agent surface treatment type active aluminium hydroxide, titanate coupling agent surface treatment type aluminium hydroxide, zinc stearate, iron oxide red, cerium oxide and 2,5-dimethyl-2,5-dihexane as raw materials to prepare the silicon-rubber composite molding material with reliable mechanical strength, excellent electrical performance, good hydrophobicity and flame retardance and better outdoor-aging resistance. The silicon-rubber composite molding material is designed for a hot die-pressing vulcanization molding production process, can be applied in production and manufacture of electrical-equipment insulation sleeves and products in related fields, and also can be applied to sealing products and damping and shock-absor
