AI Technical Summary
Existing silicone sealants are prone to mold growth in long-term humid and hot environments, and lack flame retardancy, leading to a rapid decline in their anti-mold effect and fire hazards. Furthermore, the high amount of flame retardant filler affects flexibility and compatibility.
The innovative component design of composite flame retardant and mildew inhibitor, through the synergistic effect of surface-modified aluminum hydroxide, silver-loaded nano-SiO2 and plant char-forming complex, combined with silane coupling agent treatment, achieves physical fixation of mildew inhibitor and multiple flame retardant effects, ensuring component compatibility and mechanical properties.
It achieves long-lasting anti-mildew performance (Grade 0), high-efficiency flame retardancy (UL94 V-0 grade), and maintains good mechanical properties and storage stability, avoiding component migration and phase separation.
