Novel Phosphorus Containing Flame Retarded RTV Silicone Rubbers

A reactive flame retardant cross-linker（SPTES） was successfully synthesized with dichloropentate and 3-triethoxysily-lpropylamine（APTES） in this research. Then it was further applied into the room temperature vulcanized（RTV） silicone rubber to prepare novel flame retarded RTV silicone rubbers contai...

Description
Summary:A reactive flame retardant cross-linker（SPTES） was successfully synthesized with dichloropentate and 3-triethoxysily-lpropylamine（APTES） in this research. Then it was further applied into the room temperature vulcanized（RTV） silicone rubber to prepare novel flame retarded RTV silicone rubbers containing phosphorus. The structure, thermal degradation stability, mechanical properties and flammability properties of the novel RTV silicone rubbers were tested and characterized. The results showed that the mechanical and flammability properties of the RTV silicone rubber simultaneously got better with the SPTES content increased. Compared with the sample prepared by APTES, the tensile strength of novel RTV silicone rubbers increased from 0.12 MPa to 0.38 MPa and the limit oxygen index increased from 19.8 to 23.5.
