AI Technical Summary

Technical Problem

Existing sound-insulating rubber materials suffer from problems such as increased weight, decreased performance in extreme environments, complex production processes, and high raw material costs. They may also contain harmful chemicals, making large-scale commercialization difficult.

Method used

Sound insulation performance and durability are improved by adding metal oxide complexes and specific modifying agents, including complexes of cerium dioxide, titanium dioxide and silicon dioxide, to rubber raw materials, as well as the synergistic effect of functional polymers and modified hollow glass microspheres.

Benefits of technology

It significantly improves the sound insulation performance and durability of sound-insulating rubber materials, reduces the overall weight of the materials, and ensures the stability and safety of the materials in long-term use through the flame retardant and anti-aging properties of modified additives.
