A conductive silicon rubber relates to a material used in the accessories of electric wire and cable, and comprises reinforced silicon rubber, acetylene carbon black, structural inhibitor, liquid silicon rubber and vulcanizing agent, wherein the acetylene carbon black is granular. The making process of the conductive silicon rubber is as follows: the acetylene carbon black, hydroxyl silicon oil and water are mixed according to the proportion of 100:4.5-5.5:0.2-0.5, and then are added in a granulator to be made into granules. The conductive silicon rubber has the advantages that: because acetylene carbon black, the main raw material of the conductive silicon rubber, is turned into spheric granules with the diameter approximately equal to 1 mm from the original powdery state after pretreatment, the conductive silicon rubber has increased stacking density and is nondusty and easy to disperse, thereby substantially improving manufacturing environment and doing good to the physical health of operation staff; moreover, the acetylene carbon black has good conductive effect and can meet the requirements of electrical property with a small amount of addition (15 to 22 percent). In addition, due to the addition of gluing auxiliary agent, liquid silicon rubber, the conductive silicon rubber can be well glued to insulating glue, thereby obtaining higher rate of qualified product as well as mechanical property and electrical property superior to the requirements of national standards.

The invention discloses a preparation method of Bi12SiO20, which comprises the following steps: firstly dropwisely adding etraethyl orthosilicate into a glacial acetic acid solution of bismuth nitrate, adjusting the viscosity of the dropwisely added product by anhydrous alcohol, preheating in a muffle furnace at 350 DEG C for 10 min, heating to 700-800 DEG C and calcining for 180 min, cooling to room temperature to obtain the finished product. The molar ratio of bismuth nitrate, etraethyl orthosilicate, and glacial acetic acid is 12:1.2:620; the molar ratio of bismuth nitrate and anhydrous alcohol is 12:145.
