27. SELF-LUBRICATING ANTIFRICTION MATERIAL Abstract of the Disclosure The present invention proposes a self-lubricating anti- friction material. This material comprises carbon filler in the form of a powder of fired oil coke, a powder of artificial graphite or carbon cloth; a binder in the form of epoxy resin having a molecular weight of 300-1560 obtained through con- densation of epichlorohydrin with diphenylolpropane, and poly- alumophenylsiloxane resin having a molecular weight of 5000- -15000 with a ratio of the silicon atoms to the aluminium atoms equal to 3-8; chlorinated paraffin having a molecular weight of 500-1100 and chlorine content of 40-70 mole per cent; the proportion of said components in said self-lubricat- ing antifriction material being as follows: (% by weight): Image The antifriction material can also contain a dry lubri- cant in the form of powdery boron nitride, natural graphite or molybdenum disulphide in the amount of 5-10% by weight. The above-described self-lubricating antifriction material has a number of valuable properties, namely: good self-lubricat- ing capacity, low friction coefficient, high wearability, 28. high mechanical strength and high thermal resistance. This material can be used for making components of friction units operating without lubricant, as well as for making compo- nents of friction units operating in water, kerosene, lubri- cating oil, liquid oxygen.
