This paper uses the orthogonal experimental method to study the effects of three factors (107 glue, nano-calcium carbonate, silicone oil) on tensile strength and extrudability. Experimental results show the optimal formulation: 40% 107 glue, 60% nano-calcium carbonate, and 3% silicone oil. Under this formulation, tensile strength reaches 2.63 MPa and extrudability 68.2 mL/min. Analysis shows that silicone oil content has the greatest impact on tensile strength (40.16%), while 107 glue content has the largest effect on extrudability (64.29%). These results provide valuable guidance for silicone rubber industrial production.
