Flame retardation catalyst and supported flame retardation catalyst composed of same

Abstract

The invention discloses a flame retardation catalyst and a supported flame retardation catalyst composed of same. The flame retardation catalyst has a structural formula of (A)nB, wherein A<+> is an imidazoliumcation, a quaternary ammonium cation, a quaternary phosphoniumcation, a pyrrolidoniumcation, a pyrazoliumcation or a pyridyliumcation, and B<n-> is a polyoxometallate anion. The supported flame retardation catalyst is composed of the flame retardation catalyst and clay as a supported, and the load capacity of the flame retardation catalyst is 1-50 wt% of clay. The supported flame retardation catalyst has good compatibility with polymer matrixes, helps to improve char yield and flame retardation performance of a flame retardation polymer system, and has the advantages of good thermostability and migration resistance, being friendly to environment and the like. By employing clay to support the flame retardation catalyst, the flame retardation catalyst can be uniformly dispersed in the polymer, and the char yield is improved. By employing an immersion method and without complex reaction steps, the preparation method is economical, simple, low in cost and easy to popularize.

Description

technical field [0001] The invention belongs to the field of flame retardant synergists, and in particular relates to a flame retardant catalyst capable of improving the charring quality and rate of an intumescent flame retardant and improving the efficiency of the intumescent flame retardant and a loaded flame retardant catalyst composed of the same. Background technique [0002] Because of its light weight, easy processing, and corrosion resistance, polymer materials have become indispensable materials in various fields of national defense construction and national economy. However, most polymer materials are flammable and combustible materials, and the fires caused by the ignition of polymer materials cause heavy casualties and property losses every year. How to improve the flame retardant properties of polymer materials has become a worldwide research hotspot, and the current main direction is to add flame retardants to prevent flames. However, when a certain flame reta...

Problems solved by technology

However, if the intumescent flame retardant polymer / clay composite material reaches the UL94V-0 level, it still needs to add a large amount of intumescent flame retardant, and this will cause deterioration of the mechanical properties of the material.
