What are the advantages of SPD water-based foamed polyurea sound insulation board?

SPD water-based foamed polyurea sound insulation insulation board is a composite material that combines all-water foamed polyurea foam and fiberglass mortar cloth reinforcement system. Its core advantages are reflected in five aspects: efficient sound insulation, stable thermal insulation, strong durability, wide adaptability, and green environmental protection. The specific analysis is as follows:

1. Efficient sound insulation performance

The material uses fully water-expanded polyurea foam as its core and effectively blocks sound wave transmission through its closed-cell structure. In floor sound insulation scenarios, it can significantly reduce the transmission of noises such as footsteps and equipment vibration, meeting the new national standard's high requirements for residential floor sound insulation performance. For example, in the renovation of rough houses, after using this material, the floor impact sound level can be reduced to ≤65dB, reaching the 'good house' construction standard.

2. Stable thermal insulation effect

Low thermal conductivity: The thermal conductivity of polyurea foam is low. Combined with the reinforcement of fiberglass mortar cloth, it forms a stable thermal insulation layer and reduces heat transfer. In refined floor heating systems, this material can maintain indoor temperature stability and reduce energy consumption.

Strong weather resistance: The material adapts to different humidity environments and has excellent dimensional stability. In humid areas (such as the rainy season in the south), its water absorption rate is low to avoid the degradation of thermal insulation performance caused by changes in humidity.

3. Durability and system stability

Enhanced system design: Composite fiberglass mortar cloth is used to improve the tensile strength and impact resistance of the material and extend its service life. In long-term use, it can effectively prevent problems such as cracking and falling off.

Chemical corrosion resistance: The polyurea component has good resistance to corrosive media such as acid, alkali, salt spray, etc., and is suitable for coastal or industrially polluted areas.

4. Wide scene adaptability

Rough rooms and finely decorated rooms: can be laid directly on the floor to adapt to different decoration stages. In the rough house, it serves as the basic sound insulation layer; in the finely decorated house, it is combined with the floor heating system to achieve the integration of 'sound insulation + thermal insulation'.

Compatible with floor heating systems: The material has excellent high temperature resistance and can withstand temperature changes when the floor heating system is running, avoiding deformation caused by thermal expansion and contraction.

5. Green environmental protection and convenient construction

All-water foaming process: no solvent added, reducing volatile organic compounds (VOC) emissions and complying with green building standards.

High construction efficiency: materials can be cut and spliced ​​on site to adapt to complex floor structures. In the project, the construction period is shortened by 30% compared with traditional materials, reducing labor costs.
