Embodiment Construction

[0013] The damping and sound-insulating spray mortar can completely cover all kinds of complex special-shaped structural shapes to form an effective sound-insulation layer, and can complete construction in various narrow spaces and complex environments. When the damping and sound-insulating spray mortar is used as the sound-insulation layer on the wall, it should be leveled and rubbed to complete the plastering finish. When the damping sound-insulation spray mortar is used as the ceiling sound-insulation layer, a finishing layer should be provided. Spray 20mm damping sound insulation spray mortar on the wall and ceiling of the enclosure structure, which can increase the sound insulation by 20dB(A).

[0014] When the above-mentioned damping sound insulation spraying mortar is used as the sound insulation layer of the floor, it can replace the floor leveling layer, and the spraying thickness is 30mm. It can directly cover the floor base layer and set the Ø≤20mm PVC pipeline. How...

Abstract

The invention discloses a damping sound-insulating spraying mortar. The damping sound-insulating spraying mortar is a bagged damping sound-insulating dry-blend spraying mortar prepared through mixing of an inorganic cementitious material, a filling material, an organic cementitious material and an additive under stirring; and the motor is stirred on site and uniformly sprayed on a base layer by using a spray coater. The motor comprises, by weight, 25 to 35 parts of cement, 5 to 15 parts of fly ash, 25 to 50 parts of fine and light aggregate, 10 to 40 parts of rubber powder, 0.6 to 5 parts of redispersible powder, 0.1 to 0.3 part of methylcellulose ether, 0.02 to 0.1 part of short fiber and 0.01 to 0.1 part of a water reducer. The damping sound-insulating spraying mortar can improve the sound reduction index of a wall and a ceiling when sprayed on the wall and the ceiling, and can replace a leveling layer of a floor and improve the impact sound reduction index of the floor when sprayed on the floor; and the damping sound-insulating spraying mortar can totally cover a variety of special-shape structures to form an effective sound-insulating layer and can be constructed in a variety of complex environments with narrow space.

Description

technical field [0001] The invention relates to the technical field of noise control, in particular to a damping and sound-insulating spray mortar capable of improving the sound-insulation standard of building enclosure structures. Background technique [0002] With the rapid development of modern industry, noise and vibration pollution are becoming more and more serious, and the continuous formation and expansion of various noise and vibration pollution sources have become social public hazards. With the progress of society, people have higher and higher requirements for the quality of living environment, and they are more sensitive to noise interference, and they are increasingly unwilling to endure the interference of noise pollution, and even question the existing control standards. [0003] The enclosure components and traditional crafts are mainly in the form of brick-concrete structure, and the sound insulation performance of solid clay bricks is better for the walls....
