Sound insulation mortar is a material specifically used to improve the sound insulation performance of buildings; Mainly composed of cement, sand, sound insulation filler, and high-quality additives. These ingredients are automatically measured and mixed, with good workability, strong adhesion to the substrate, and low shrinkage rate; It effectively reduces the propagation of sound through specific ingredients and processes, creating a quieter and more comfortable living environment. Soundproofing mortar is widely used in building structures such as walls, floors, and roofs, especially in noisy environments such as residential buildings, offices, and entertainment venues.

Main product features:
1. Excellent sound insulation performance:
The main characteristic of soundproof mortar is its excellent sound insulation effect. It can effectively reduce the propagation of sound and minimize the impact of noise on indoor environments. This is mainly due to the presence of special sound insulation fillers inside, which can absorb or compress stored sound wave energy, thereby hindering the propagation of sound waves.
2. Good workability:
Soundproofing mortar has good workability, which means it is easy to mix and apply. After adding water, it can be used directly without the need for complex preparation processes. This feature makes construction more convenient and efficient.
3. Strong substrate adhesion:
The bonding force between soundproof mortar and substrate is very strong, which ensures its stability and durability after construction. Even during long-term use, it will not easily fall off or crack.
4. Low shrinkage rate:
The shrinkage rate of soundproof mortar is relatively low, which means that the volume change is small during the hardening process, reducing the problem of cracks caused by shrinkage.
5. Excellent construction performance:
The construction performance of soundproof mortar is good, and there is no need to increase the main structural cost of the project during the construction process. Moreover, the construction is convenient and cost-effective. Its construction method is similar to other types of mortar, so construction personnel can quickly get started.
6. Thermal insulation effect:
In addition to sound insulation, sound insulation mortar also has a certain insulation effect. It can serve as a multifunctional material that not only provides sound insulation, but also helps regulate indoor temperature and improve living comfort.
7. Environmental performance:
Soundproof mortar is usually made of inorganic materials and does not contain harmful substances to the human body. It is a green and environmentally friendly building material. In addition, its production and use help reduce the discharge of industrial waste and have good environmental protection benefits.
8. High strength and fire resistance:
The bonding strength between soundproof mortar and base layer is high, and it is not easy to produce cracks and hollowing. At the same time, it also has fire-resistant and flame-retardant properties, which can provide additional safety protection in the event of a fire.
Thermal insulation and sound insulation of exterior walls, roofs, floors, and other parts of buildings.
