AI Technical Summary

Technical Problem

Existing waterproof and fire-retardant coatings are prone to key defects such as decreased adhesion, mutual restriction between flame retardancy and waterproof performance, and insufficient weather resistance of the coating in special humid environments, resulting in unstable performance.

Method used

A combination of composite base materials, composite flame retardants, nano waterproofing agents, moisture-proof additives and functional fillers is used. Through a composite system of silicone-modified resin and epoxy resin, combined with core-shell structure nano waterproofing agents and modified bentonite, a molecular-level moisture-proof barrier is formed, a super-hydrophobic surface and a dense barrier layer are constructed, and gradient polymerization and radiation curing processes are used to optimize the cross-linking network.

Benefits of technology

It maintains good adhesion and flame retardant properties in humid environments, significantly enhances the fire resistance and waterproof performance of the coating, and achieves high-efficiency flame retardant and waterproof and moisture-proof stability.
