Retardant nanocomposites

Although the use of fine flame can effectively improve the flame retardancy of the polymer,

but there are some problems, such as can not effectively control the release of toxic gases

and the generation of a lot of smoke, flame retardant will affect the mechanical properties

of the polymer , will result in a certain environment

Affected. Therefore, the study and the polymer / layered inorganic nanocomposites will be

able to meet the above requirements and has good flame retardant properties. Nanocomposites

are in effect one or more of the material with nano size or molecular level uniformly

dispersed in another

Matrix components. According to foreign sources, the treated material due to the presence

of ultra-fine size, so its properties than the corresponding macro-or micro-grade

composites are greatly improved. Currently in the laboratory has prepared nano epoxy resin,

polystyrene

, Polypropylene, nylon-6, composite materials such as acrylic. Such as nylon-6 /

montmorillonite (4.2%) nanocomposites tensile strength than pure nylon-6 increase 50%, the

glass transition temperature than pure nylon-6 increased about 90 ℃; while heat release

efficiency than pure nylon - 6 to be very low in

More.
Polymer / layered inorganic nanocomposite filler than conventional far superior mechanical

properties, thermal properties, flame retardancy, anisotropy. Abroad has polymer / layered

inorganic nanocomposites for the manufacture of automotive engine parts, and prepare

Used in aircraft interior materials, fuel tanks, electronic or electrical components,

structural components within the housing, brake and tire manufacturing.
An oxide nano plastic flame retardant (CuO, ZnO, Fe2O3, etc.) and complex compound, its method of

preparation to use more liquid phase prepared nanoparticles. There are the usual liquid-

phase method: direct precipitation, sol - gel method, co-precipitation method. In addition,

microwave synthesis,

Arc method.
