The invention provides a rubber composition for a tire base, a rubber compound for the tire base and a preparation method of the rubber compound. The rubber composition is prepared from the following components in parts by weight: 100 parts of rubber, 20 to 55 parts of carbon black, 10 to 25 parts of white carbon black, 0.5 to 15 parts of an anti-aging agent, 0.5 to 10 parts of an active agent, 0.2 to 5 parts of a vulcanizing agent, 0.2 to 5 parts of an accelerant and 2 to 10 parts of an auxiliary agent, the anti-aging agent comprises a p-phenylenediamine anti-aging agent, the chemical structural general formula of the p-phenylenediamine anti-aging agent is # imgabs0 #, and R1 and R1'are respectively and independently selected from any one of C1-C18 chain alkyl, alicyclic hydrocarbon and hydrogen; r < 2 > and R < 3 > are independently C1-C18 chain alkyl groups or an aliphatic ring formed by R < 2 > and R < 3 >; r < 4 > and R < 5 > are independently C1-C18 chain alkyl groups or an aliphatic ring formed by R < 4 > and R < 5 >. The rubber composition is environment-friendly and non-toxic.
