| titleOfInvention | A kind of controllable thermosetting silicone polyurea resin and preparation method thereof |
| abstract | The invention relates to a controllable thermosetting organosilicon polyurea resin and a preparation method thereof. The controllable thermosetting type is a controllable thermosetting type that firstly polymerizes an amino capping agent and a cyclic monomer to obtain an amino-terminated polysiloxane, and then undergoes Michael addition reaction with a preset amount of acryloxy substances to obtain a preset number of active hydrogens. Silicone polyurea resin avoids the relatively active chemical properties of the existing polyether polyurea resin, insufficient chemical resistance stability; high electron cloud density, poor UV fastness, insufficient weather resistance, high glass transition temperature, and cold resistance. Insufficient properties and other defects, a controllable number of >NH-(imino groups ) are formed through the Michael addition reaction, which overcomes the shortcoming of the rapid reaction of ‑NH with isocyanate to gel, and its curing and gel time is controllable, which is more conducive to large scale construction. This product and its technology can be used in the field of heavy-duty anticorrosion and functional materials. |
