Problems solved by technology

[0003] The flame retardant commonly used in polystyrene foam is hexabromocyclododecane. Hexabromocyclododecane has excellent flame retardant effect, but when used as a flame retardant, hexabromocyclododecane Hydrogen bromide becomes violent, and the hazards of hydrogen bromide vapor will be more significant
[0004] Although the most commonly used halogenated flame retardants in flame retardants have unparalleled efficiency in other flame retardant series, their harm to the environment and people cannot be ignored.

Abstract

The invention discloses an environment-friendly methyl octabromoether flame-retardant master batch as well as a preparation method and application thereof, and relates to the technical field of flame-retardant materials, the environment-friendly methyl octabromoether flame-retardant master batch comprises the following components in parts by weight: 35-65 parts of methyl octabromoether, 5-30 parts of a stabilizer and 40-60 parts of polystyrene. The environment-friendly methyl octabromo-ether flame-retardant master batch prepared by the invention is high in oxygen index, the vertical burning UL 94 level can reach V0 level, the flame-retardant effect is very good, toxic gas is not generated in the flame-retardant process, the environment-friendly requirement is met, and the environment-friendly methyl octabromo-ether flame-retardant master batch can be widely applied to preparation of extruded polystyrene foam plastic (XPS).

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to an environment-friendly flame retardant master batch of methyl octabromo ether and a preparation method and application thereof. Background technique [0002] Polystyrene foam is made of polystyrene resin as the main body, adding additives such as foaming agents. It is the most used buffer material. It has a closed-cell structure, low water absorption, excellent water resistance, and low density. , good mechanical strength, excellent cushioning performance; good processability, easy molding, good coloring, strong temperature adaptability, excellent radiation resistance, etc., and high dimensional accuracy, uniform structure, so its use rate in exterior wall insulation is very high. high. [0003] The commonly used flame retardant for polystyrene foam is hexabromocyclododecane. Hexabromocyclododecane has excellent flame retardant effect, but when used as a flame...
