METHOD OF PREPARING RUBBER COMPOUND Russian patent published in 1997 - IPC

Abstract RU 2099362 C1

FIELD: rubber industry. SUBSTANCE: uncured rubber is mixed, in rubber mixer, with carbon black, sulfur-containing curing group, target additive, and rubber waste. The latter constitutes crushed wastes of polyamide and viscose rubber-covered uncured cords which are preliminarily crushed on rotor tyre-cutter-type crusher with rotation speed 600 rpm using double passage of waste through 6-8-mm clearance between mobile and stationary knives. Further, waste is crushed on muller with 2 rolls, clearance 0.35-0.65 mm, friction 1: 3.08 - 3-4 passages are recommended. The operation is repeated on muller wherein one roll is smooth and the other wavy (3-4 passages). Resultant sheet 3.5-6.5 mm thick is disintegrated on noodle-cutter-type crusher with rotation speed 375 rpm and 0.2-0.3 mm clearance between mobile inclined knives and stationary knife. Disintegration is performed across threads oriented by "calender effect" when treated on mullers. Material is once again treated on mullers and noodle-cutter-type crusher. 2 to 10 weight parts of thus treated waste is mixed with 100 weight parts of uncured rubber. Characteristics of resultant rubber: apparent tensile strength 165-173 kg/sq.cm; elongation 483-510%; hardness 63-66 conditional units, frame run 4700-4850 rm. EFFECT: improved performance characteristics. 1 dwg , 1 tbl
