| Abstract: | The effects of vinyl silicone oil and hy-drosilicone oil on mechanical properties of liquid silicone rubber were investigated. The results showed that by adding vinyl silicone oil with mass fraction of 10% , the mechanical properties of silicone rubber could be greatly improved. By adding 10 phr vinyl silicone oil with 10% mass fraction of vinyl agent,4. 6 phr hydrosilicone oil, reinforced by 20 phr of surface modified silica, a vulcanized silicone rubber could be prepared with tensile strength 3. 8 MPa, tear strength 7. 6 kN/m and elongation at break 162%. |
