Patent application number 201510277994.6 (a method for preparing a highly thermally stable inorganic hybrid flame retardant) discloses a method for preparing a highly thermally stable inorganic hybrid flame retardant. The preparation principle is to combine graphene oxide with soluble hypophosphite Simple compounding with soluble aluminum salts, and then melt-extruding the two composite flame retardants with PBT to prepare flame-retardant materials. One disadvantage of this method is that hydrophilic graphene oxide and PBT are prone to phase separation during the combination process. , thus affecting the performance of subsequent products

Abstract

The invention provides a biomass graphene-modified fire retardant and master batch and a preparation method thereof. The biomass graphene-modified fire retardant is mainly prepared from biomass graphene, a fire retardant and a coupling agent. The fire retardant is used as a disperse medium for the biomass graphene. By simple physical mixing, bond joint of the biomass graphene with the fire retardant and uniform dispersion of the biomass graphene are realized, thus finally playing a synergistic flame retardant effect in a polymer matrix. By the adoption of the Biomass graphene-modified fire retardant for preparation of high-molecular polymer master batch, the dispersion problem of biomass graphene is solved, and it is possible to effectively raise fire resistance under the condition of low addition amount of the fire retardant. For practical application fields of different fire-resistant high-molecular polymer materials, anti-dripping, enhancing, ultraviolet-resistant and coloring functions can be obtained simultaneously by the adoption of the master batch product.

Description

technical field [0001] The invention relates to the technical field of processing and modification of polymer materials, in particular to a biomass graphene modified flame retardant, a masterbatch and a preparation method. Background technique [0002] As the most widely used organic material in today's society, the improvement of its flame retardant performance is an important issue that manufacturers have been studying deeply. The flame retardancy of polymers is a key performance indicator in applications such as fibers, flooring, building and construction materials, pipes, wires, cables, and conveyor belts including mining. [0003] In flame retardant technology, there are three basic principles widely used in the field of polymer flame retardant modification research: (1) gas phase flame retardant mechanism; (2) endothermic flame retardant mechanism; (3) condensed phase flame retardant mechanism. [0004] Among them, the gas-phase flame retardant mechanism is to reduce...
