Study on the Application of Core-shell Catalyst in Low Combustion Flue Gas Toxicity Materials
This article discusses the core-shell structure of CuO@γ-Al2O3 composite particle catalyst was added to low smoke halogen-free flame retardant polyolefin materials to prepare low smoke toxicity low smoke halogen-free flame retar-dant polyolefin composite materials. The effects of the composite particle catalyst on the combustion smoke toxicity,flame retardant performance,mechanical and physical properties,ozone resistance,thermal aging performance,oil resistance,and acid-base resistance of the composite materials were investigated. The results show that the addition of core-shell struc-ture catalysts can reduce the smoke toxicity of composite materials,and reduce the mechanical and physical properties,thermal aging properties,and oil resistance of the composite materials,while having little effect on the flame retardant per-formance and acid alkali resistance of the materials.
