Self-leveling lightweight sound insulation mortar prepared from waste rubber
The invention provides a self-leveling lightweight sound insulation mortar prepared from waste rubber. The self-leveling lightweight sound insulation mortar is prepared from the following raw materials: 25-40% of 42.5-grade Portland cement or ordinary Portland cement; 1-3% of glass beads; 1.5-3.5% of rubber particles with the particle size of 16-40 meshes; 1-3% of rubber particles with the particle size of 40-70 meshes; 30-45% of natural sand with a particle size of 40-70 meshes; 15-25% of natural sand with a particle size of 70-140 meshes; 0.5-1% of a modifier; 0.8%-1.5% of a water reducing agent; 1.2%-2.0% of redispersible latex powder; and 0.05%-0.2% of cellulose ether HPMC. According to the invention, the problems of layered floating and poor cohesiveness of rubber particles can be effectively solved, and the sound insulation mortar with high flow state, high strength and low impact sound pressure level is prepared.
本发明提供一种利用废旧橡胶制备自流平轻质隔声砂浆，其原料如下：42.5级硅酸盐水泥或普通硅酸盐水泥25～40％；玻化微珠1～3％；粒径16‑40目的橡胶颗粒1.5～3.5％；粒径40‑70目的橡胶颗粒1～3％；粒径40‑70目的天然砂30～45％；粒径70‑140目的天然砂15～25％；改性剂0.5～1％；减水剂0.8％‑1.5％；可再分散乳胶粉1.2％‑2.0％；纤维素醚HPMC0.05％‑0.2％。本发明可有效地解决橡胶颗粒分层上浮、粘聚性差的问题，制备出兼具高流态、高强度和低撞击声压级的隔声砂浆。
