Description

Technical field: [0001] The invention relates to the field of polymer materials, in particular to a high-strength and high-flame-retardant organic silicon foam material and a preparation method thereof. Background technique: [0002] The foam materials currently on the market are mainly polyurethane foam plastics. However, the flame retardancy of polyurethane foam plastics is not ideal, and the limiting oxygen index (LOI) is only 19%, which belongs to a kind of flammable material. If it is used in the field of construction transportation, its safety cannot be effectively guaranteed. Therefore, the research and development of a new foam material with high flame retardant properties is very necessary. [0003] Silicone rubber is a kind of linear polysiloxane compound with silicon-oxygen bond as the main chain and side groups of silicon atoms connected to organic groups such as methyl, phenyl and vinyl groups. Silicone rubber foam material, also known as sponge silicone rubbe...
