Description

technical field

[0001] The invention belongs to the technical field of flame-retardant materials, and in particular relates to a cage-shaped polysilsesquioxane-based modified cross-network polymer containing mercaptopentaerythyl ester and a preparation method thereof. Background technique

[0002] Silicone rubber materials are widely used in industrial production and daily life. They have certain combustion self-extinguishing properties, but their flame retardancy is poor. High flame-retardant silicone rubber is still the focus of current research. At present, the flame retardants that can be used for silicone rubber can be divided into two categories: halogen-containing flame retardants and halogen-free flame retardants. Due to the great environmental pressure of halogen-containing flame retardants, many countries have banned their use. Burning silicone rubber is a research hotspot.

[0003] The flame retardants used in halogen-free flame-retardant silicone rubber mainly i...
