| Abstract: |
| The effects of structured control agents hydroxy silicone oil，methoxy silicone oil and dimethyl diethoxysilicone oil on the performance of silicone rubber were studied using methyl vinyl silicone rubber as the main material.The results showed that the addition of structured control agent could inhibit the structured phenomenon of silicone rubber，reduce the degree of cross-linking，hardness，modulus at a given elongation，tensile strength，rebound value and compression set of silicone rubber，and increase the elongation at break.Hydroxyl silicone oil had the best inhibitory effect on the structuring of silicone rubber，which could reduce the storage modulus of silicone rubber（pinching compound） and prolong the storage time，while a better effect could be achieved when hydroxyl silicone oil amount was 6 phr. |
