AI Technical Summary
The existing polyurethane color steel panels have insufficient flame retardant properties and cannot meet the Class A non-combustible requirements. They also have problems such as flame retardant migration, high smoke toxicity, and poor adhesion to the surface material, making it difficult to meet the requirements of the new fire protection code.
It adopts PIR-organic-inorganic nanocomposite core material, combined with reactive and solid flame retardants, equipped with ceramic microbubble fireproof coating and interface compatibilizer, and achieves high flame retardancy, low smoke and low toxicity by optimizing process parameters, making it suitable for continuous production.
It achieves non-combustible combustion performance, forms a dense carbonized layer, has low smoke toxicity, high bonding strength, meets the long-term service requirements of buildings, complies with green and environmental protection requirements, and improves production stability and market competitiveness.
