Abstract

The invention relates to the technical field of polymer flame retardance, in particular to a sulfonyl-containing polyphenyl silicon boron flame retardant and a preparation method thereof. The preparation method of the sulfonyl-containing polyphenyl silicon boron flame retardant comprises the steps that a phenyl siloxane monomer, a silane coupling agent and trimethyl borate are mixed according to a specific weight ratio, and subjected to ahydrolytic polycondensation reaction under an acidic condition, and graft copolymerization is carried out on p-styrenesulfonate, so that the formed sulfo-group-containing polyphenyl silicon boron flame retardant is a polymer, has a better flame-retardant synergistic effect, improves the flame-retardant effect, has better compatibility with polycarbonate and is not easy to migrate, thereby having good long-acting flame retardancy; and the preparation method is simple to operate, convenient to control, high in production efficiency and low in production cost, and can be used for large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer flame retardant, in particular to a polyphenyl silicon boron flame retardant containing sulfonic acid groups and a preparation method thereof. Background technique [0002] The development of highly efficient flame retardants for thermoplastics and thermosets is a huge demand for many industrial applications, and silicone-based flame retardants are a key area of ​​development. However, it has the problems of high addition amount and insufficient flame retardant efficiency. [0003] Some organic groups can endow siloxane with more special properties, and the introduction of sulfonate can endow polysiloxane with catalytic flame-retardant effect on PC. Organic sulfonates such as diphenyl sulfone sulfonate (KSS), which are now available in industrial applications, have good catalytic and flame-retardant effects on PC, but they are small molecules, lack physical entanglement with PC, and are easy to p...
