Abstract

The present invention relates to processing of polymer and is especially a kind of composite nano rectorite/thermoplastic polyurethane elastomer material prepared through smelting and blending process. Owing to the surface and interface effect of the nano particle, the composite material of the present invention has its mechanical performance and heat performance superior to those of traditional composite material in the same chemical composition. The composite material is prepared with thermoplastic polyurethane elastomer of different kinds 100-150 weight portions, organic rectorite clay 1-10 weight portions and demolding agent 1-5 weight portions and through simple pollution-less smelting and blending process. The composite material has wide application.

Description

1. Technical field:

[0001] The invention belongs to the field of polymer processing, in particular to a rectorite / thermoplastic polyurethane elastomer nanocomposite material prepared by a melt blending method. 2. Background technology:

[0002] Organic-inorganic nanocomposites are known as "new materials of the 21st century". Compared with traditional composite materials, due to the surface and interface effects brought by nanoparticles, nanocomposites have better mechanical and thermal properties than conventional composite materials with the same chemical composition. At present, the clay nanocomposites that have been reported mainly include polyamide (imide) / montmorillonite, unsaturated polyester / layered clay, polystyrene / clay, polypropylene / clay, styrene-butadiene rubber / clay, Carboxylated nitrile rubber / clay, etc., wherein the clay is mainly montmorillonite.

[0003] Thermoplastic polyurethane elastomer (TPUR) is a kind of special and widely used polymer material whos...
