Organosilicon joint sealing material with low cost and high performance

The invention provides organosilicon joint sealing materials with low cost and high performance. A product prepared from the organosilicon joint sealing materials comprises the following components in proportion by weight: 100 alpha, omega-dicarboxylic dimethyl polysiloxane, 5 to 70 filler reinforcement agents, 0.5 to 12 crosslinking agents, 1 to 5 o coupling agents, 41 to 80 dimethyl polysiloxane, 1 to 8 deep-layer crosslinking accelerant and 6 to 14 tackifier, wherein the alpha, omega-dicarboxylic dimethyl polysiloxane and the filler reinforcement agents are added into a vacuum kneader, dehydrated and mixed to obtain base materials, the base materials are moved in a high-speed dispersator, and stirred and mixed with other components in a high-speed mode, and finally the crosslinking accelerants are added to carry out chemical reaction to obtain the joint sealing materials. Various raw materials used by the invention can be bought in the market; thereby the invention has low manufacturing cost, high performa
