MIXTURE FOR PRODUCING A NOISE-DAMPING COMPOUND, ESPECIALLY FOR RAILWAY INSTALLATIONS |
| 摘要 |
A mixture for producing a noise-damping compound is formed from a plastic dispersion, cement and an inert additive, where the dispersed plastic has a temperature T lambda max </= -50 DEG C or under and predetermined tensile and residual expansion, and the cured mixture has internal hollow spaces amounting to at least 12 % by volume. Such a mixture is especially suitable for reducing railway traffic noise. |
