A new type of curing system for silicone rubber was studied for the first time by using polysiloxanes containing chloropropyl groups (CPPS) as the gum and poly(dimethyl-co-3-aminopropylmethyl) silicone oil (APPS) or poly(dimethyl-co-3-(2-aminoethylamino)propyl) silicone oil (AEAPPS) as a crosslinker. The effect of various factors on the silicone rubber was investigated in detail. Better technical conditions were determined and the silicone rubber with excellent mechanical properties was successfully obtained. The tensile strength, tear strength, and elongation at break of the silicone rubber reach 10.25 MPa, 41.87 kN/m, 1365%, respectively. Crosslinking density of the silicone rubber was measured by toluene-swelling method to analyze the crosslinking status. The crosslinking mechanism of the new curing system was also discussed.
