Addition type liquid silicone rubber, vulcanized rubber and preparation methods of addition type liquid silicone rubber and vulcanized rubber

The invention relates to addition type liquid silicone rubber, vulcanized rubber thereof and preparation methods of the addition type liquid silicone rubber and the vulcanized rubber. The addition type liquid silicone rubber contains vinyl silicone oil, hydrogen-containing silicone oil, white carbon black, a platinum catalyst and an inhibitor, and also contains halogenated aniline. Due to the addition of the halogenated aniline, the positive vulcanization time of the liquid silicone rubber is remarkably shortened, meanwhile, the physical and mechanical properties such as hardness, tensile strength and elongation at break of the obtained vulcanized rubber are basically kept unchanged, or the vulcanization temperature or the dosage of the platinum catalyst can be reduced under the condition that the positive vulcanization time is kept unchanged. Therefore, the liquid silicone rubber prepared by the invention has the advantages of high vulcanization speed, simple preparation method, cheap and easily available ra
