Zusammenfassung: | The invention discloses a preparation method for addition type liquid silicone rubber with tracking corrosion resistance. According to the method, vinyl silicone oil is taken as basic polymer, hydrogen-contained silicone oil is taken as cross-linking agent, white carbon black is taken as necessary reinforcing filler, the content of platinum catalyst in a formula is improved to regulate and control the thermal decomposition characteristics of the addition type liquid silicone rubber, adjacent methyls in the thermal decomposition process of the addition type liquid silicone rubber are accelerated to be subjected to crosslinking, the breakage decomposition of a main chain is inhibited so as to improve the crosslinking density and the thermostability of the addition type liquid silicone rubber, and finally, the tracking resistance and the erosion performance of the addition type liquid silicone rubber are finally improved. Through the preparation method disclosed by the invention, the addition type liquid silicon |
