Detailed information on the preparation and application of antiozonants to the production of rubber has been collected from the patents published till 1987 inclusive. From among the numerous organic compounds acting as antiozonants and antioxidants, several classes can be distinguished and grouped on the gasis of the type and number of heteroatoms in their molecules: N1, N2, N3, N4, N1O2, O2S1, O1, P2S4, P1 etc. The principal method used for the synthesis of antiozonants depend on the type of the chemical compound and the initial products which are mostly obtained from petroleum. N-alkyl, N'-aryl-paraphenylene diamines and quinolines are the most appropriate antiozonants under dynamic conditions, whereas N,N'-dialkyl-paraphenylene diamines and nickel dithiocarbamate suit static conditions. Among nonstaining antiozonants, some phosphorus and sulphur-containing compounds are used. Antiozonants are usually added to rubber mixtures along with various waxes. |
