Problems solved by technology

The advantages of halogenated flame retardants are good flame retardant effect, less dosage, less influence on material properties and good price. However, polymer materials containing halogenated flame retardants will produce a lot of smoke and dust when they are thermally cracked or burned. Corrosive gas, polluting the environment, relevant industry must look for other flame retardants to replace halogenated flame retardants

Abstract

The invention provides a flame-retardant silicon-based thermoplastic vulcanizate and its synthesis method, which includes providing a flame-retardant thermoplastic polyurethane synthesis raw material, performing a prepolymer synthesis step, and performing a dynamic vulcanization step. The synthetic raw materials of flame-retardant thermoplastic polyurethane include polyisocyanate compounds, macromolecular polyol compounds and small molecular polyols. The prepolymer synthesis step is used to obtain a silicon-based thermoplastic vulcanizate prepolymer. The dynamic vulcanization step is used to obtain a flame-retardant silicone-based thermoplastic vulcanizate. Accordingly, the flame-retardant silicon-based thermoplastic vulcanizate of the present invention has excellent flexibility, permanent flame-retardant behavior, permanent weather resistance, smooth feeling, and permanent pseudo-wear resistance.

Description

technical field [0001] The invention relates to a flame-retardant silicon-based thermoplastic vulcanizate and a synthesis method thereof, in particular to a halogen-free flame-retardant silicon-based thermoplastic vulcanizate and a synthesis method thereof. Background technique [0002] In recent years, the application market of silicon-based thermoplastic vulcanizate (TPSiV) has become more and more extensive. Its advantage is that it combines the performance advantages of thermoplastic polyurethane and silicone materials, and has excellent wear resistance, silky touch, lower than thermoplastic. Polyurethane has the advantages of surface friction coefficient, excellent adhesion with PC, PC / ABS, ABS and other resins, high physical and mechanical properties after hot air aging, and easy extrusion and injection molding. The disadvantage of vulcanized rubber is that it does not have flame retardant properties, which limits its application range. [0003] However, the known the...
