SOUND INSULATING MATERIAL, SOUND INSULATING PLATE AND PARTITION STRUCTURE OF TRAIN CARRIAGE
A sound insulating material, a sound insulating plate, and a partition structure of a train carriage are provided. The sound insulating material comprises the following components in weight ratio: 2-8 parts of tricalcium silicate; 4-10 parts of calcium hydroxide; 10-30 parts of aluminosilicate; 4-10 parts of alumina; 5-15 parts of iron oxide; 10-30 parts of a binder; and 5-10 parts of a curing agent, wherein the binder is at least two of lithium silicate, sodium silicate and calcium silicate; the curing agent is at least one of lithium oxide, magnesium oxide and silica; and the mixture of the aluminosilicate, alumina and iron oxide expands at 1000° C.-1350 ° C. to form particles. The sound insulating plate made of this material is lightweight and has a sound insulation capacity of 35-42 dB.
