Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a hydrotalcite intercalated flame-retardant reinforced polypropylene material and a preparation method thereof. Background technique [0002] At present, the nano-modified materials of polymers mainly include nanoparticles and layered silicates. Layered silicates mainly include montmorillonite, double hydroxy metal composite oxides and so on. The modification of montmorillonite can improve the thermal stability, barrier performance, and combustion performance of the polymer matrix, but when the polymer is modified by montmorillonite, the thermal stability of the main organic intercalation agent quaternary salt is poor, and it can be used in composite materials. During processing, it is easy to decompose and make the matrix turn yellow. The thermal stability of hydrotalcite is better than that of montmorillonite, and its structure is very similar to that of m...
