In order to discover the bonding mechanism of self-adhesive silicone rubber tape, we prepared a self-adhesive silicone rubber tape through the reaction of boric acid and methyl-vinyl silicone rubber. The variation of bonding force at interface of self-adhesive silicone rubber tape with temperature and soaking time was traced by tensile tests, and the self-fusion effect was verified. A physical model of self-fusion effect was proposed with the help of infrared spectrum test. The results show that when the content of boric acid in the reaction system is 2.5%, the self-adhesive tape has the highest initial bonding force. When silicone rubber has the molecular structure of short chain boron-containing siloxanes imbedded in long chain siloxane network, the well contacted silicone rubber interfaces can bond through complexation between boron and oxygen atoms in the boron-containing siloxanes, and the bonding force is stronger than the cohesion among polysiloxane molecules. The complexation can not complete instantly, and the higher the temperature of interface, the shorter the time of complexation. Under 60℃, the complexation strength can reach the optimum value within 12 hours.
