Lining for friction wheels for mining equipment. Sebe, Octavian Mircea; Banciu, Mircea Savu (Institutul de Cercetari Miniere, Rom.). Rom. RO 61749 5 Oct 1976, 2 pp. (Romanian). (Romania). CODEN: RUXXA3. CLASS: IC: C08L027-06. APPLICATION: RO 72-69485 21 Jan 1972. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) A title lining is manufd. from PVC [9002-86-2] 100, di-2-ethylhexyl phthalate (I) [117-81-7] 40-50, di-Bu phthalate (II) [84-74-2] 20-30, p,p'-diphenylolpropane (III) [80-05-7] 1-1.5, tribasic Pb sulfate (IV) [12202-17-4] 5-7, and Ca stearate (V) [1592-23-0] 0.5-1. Thus, PVC 100, III 1, IV 5, dibasic Pb phosphite [12141-20-7] 2, and V 0.5 kg are mixed for 5 min, followed by addn. of 45 g I and 24 g II. The mixt. was further mixed for 10 min and processed as usual to give a material of high mech. strength and temp. resistance from -50 to +50°.
