Abstract

The invention provides a hydrophobic flame retardant and a preparation method thereof, and relates to the technical field of flame retardant modification. The hydrophobic flame retardant contains 70-95% by mass of a flame retardant and 5-30% by mass of a modifier; the flame retardant is one or more of an inorganic flame retardant, a component of a compound intumescent flame retardant and a simplesubstance type intumescent flame retardant; the modifier is one or more of tetraethyl silicate, vinyl trimethoxy silane, vinyl triethoxy silane, vinyl tri(2-methoxyethoxy) silane, polyoxyethylene octyl phenol ether-10, dodecyl trimethoxy silane, dodecyl triethoxy silane, hexadecyl trimethoxy silane, hexadecyl triethoxy silane, octadecyl trimethoxy silane and octadecyl triethoxy silane. The hydrophobic flame retardant is prepared through multiple surface modification, the flame retardant is endowed with high hydrophobicity, meanwhile, the flame retardant performance of the flame retardant is improved, the compatibility between the flame retardant and a polymer matrix is good, the preparation method is simple, and the cost is low.

Description

technical field

[0001] The invention relates to the technical field of flame retardant modification, in particular to a hydrophobic flame retardant and a preparation method thereof. Background technique

[0002] Combustible polymer materials, which are widely used in modern life, have become one of the main ignition materials for fires, especially urban fires and building fires, and their fire hazards are increasingly concerned and valued by people.

[0003] Halogenated flame retardants (mainly brominated flame retardants and chlorine-based flame retardants) have high flame retardant efficiency, but they will produce acidic substances and dioxins during the flame retardant process, which will have adverse effects on humans and the environment . Inorganic flame retardants based on aluminum hydroxide and magnesium hydroxide and intumescent flame retardants mainly composed of phosphorus and nitrogen compounds do not contain halogens and are relatively environmentally friendly ...
