Abstract

The invention discloses a metal hybrid POSS flame retardant as well as a preparation method and application thereof. The chemical structural formula of the metal hybrid POSS flame retardant is shown in the specification, wherein R is -H or a group disclosed in the invention. The metal hybrid POSS flame retardant is obtained by taking oligomeric polyhedral silsesquioxane (POSS-NH2) as a raw material through vertex-opening, vertex-capping and nucleophilic substitution chemical reaction. The synthesized POSS derivative simultaneously contains three flame-retardant elements, namely silicon, phosphorus and zirconium, and can be used as an efficient flame retardant to modify various polymers, so that the application range of the polymers is expanded.

Description

technical field

[0001] The invention relates to a metal hybrid POSS flame retardant, a preparation method and an application. Background technique

[0002] Oligomeric polyhedral silsesquioxane POSS-NH 2 It is an important class of nano-hybrid organic-inorganic compounds with a cage structure composed of silicon and oxygen, with a size of 1-3nm and can be considered as the smallest silicon-containing particle. Silicon-containing materials are promising for the preparation of molecularly dispersed nanocomposites due to their inorganic Si-O frameworks being close to silicon. It is worth noting that the Si atoms at the cage corners of each POSS molecule may be connected with reactive or non-reactive organic groups, which makes the POSS nanostructures and polymers compatible. Polymers modified by POSS derivatives have high strength, good corrosion resistance and excellent thermal stability, etc., so that such compounds have wide application potential in the field of hybrid nano...
