FIELD: chemistry. ^ SUBSTANCE: invention relates to industrial rubber and particularly to rubber mixtures for making frost resistant cushion blocks for railway line braces. The rubber mixture consists of the following in pts. wt: natural rubber - 100, zinc oxides - 5-10, crumbs made from corks - 10-15, P-514 technical carbon - 20-25, P-701 technical carbon - 15-25, technical sulphur - 1-2, acetonanil P - 1-2, sulfonamide C - 1.5-2.0, diaphene FP - 1-2, stearin - 1-2. ^ EFFECT: cushion blocks made from the said mixture have low residual deformation, high frost resistance, high noise and vibration damping capacity. ^ 3 tbl |
