The invention relates to the technical field of building materials, and discloses rubber particle modified sound insulation
mortar for buildings and a preparation method thereof.The rubber particle modified sound insulation
mortar for the buildings is prepared from, by
mass, 8-15 parts of modified rubber, 29.4-44.8 parts of
cement mortar, 40-50 parts of aggregate and 8.5-15.9 parts of admixtures,
waste rubber is smashed to form rubber particles, then the rubber particles are sieved, and the sieved rubber particles are dried to obtain the sound insulation mortar for the buildings. Rubber particles are soaked in a modifier to form an intermediate with a
rough surface, then the intermediate is fished out, cleaned and dried, then the intermediate is soaked in emulsified
asphalt for modification to prepare modified rubber, the modified rubber is fished out of the emulsified
asphalt, and the modified rubber is stirred and mixed with
cement mortar, aggregate and an additive to form the rubber particle modified sound insulation mortar. According to the sound insulation mortar and the preparation method thereof, the
waste rubber is reused to prepare the sound insulation mortar, layering between the rubber and the mortar is avoided, the strength of the sound insulation mortar is guaranteed, and the safety of the sound insulation mortar is improved.
