Entropy Energy Innovation Materials (Zhuhai) Co., Ltd. applied for a patent entitled "a sulfonate grafted silicone flame retardant and its preparation method and application", publication No. CN 118755031A, with the application date of June 2024.
The invention discloses a sulfonate grafted silicone flame retardant and a preparation method and application thereof, belonging to the technical field of thermoplastic resin products. The sulfonate grafted silicone flame retardant disclosed in the invention is a core-shell structure, comprising organic silicon as a core and sulfonate grafted on the surface of the organic silicon as a shell and a third monomer. When the sulfonate is dispersed in a thermoplastic resin material, the three can play a synergistic flame retardant role. The flame retardant can achieve the UL94V0 flame retardant level of 1.2mm thin-walled products under the condition of low addition amount, and the addition of the flame retardant does not affect the physical and mechanical properties of the matrix resin.
