Abstract

The invention provides a low-density nano composite material, relating to the technical field of nano materials. The low-density nano composite material is prepared from the following raw materials: nano powder, a foaming agent, grafted polyolefin, low-density polyethylene, a coupling agent, a dispersing agent, an inorganic filler, a foaming agent and a toughener. The low-density nano composite material has the advantages of favorable properties and high stability. By adding the nano powder and other raw materials into the low-density polyethylene, the wear resistance of the nano composite material is enhanced under the under actions of the combination of the raw materials. The toughener increases the toughness of the nano composite material. Thus, the nano composite material has wide application range.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a low-density nanocomposite material. Background technique [0002] Nanocomposites are based on resin, rubber, ceramics and metal as the continuous phase, and nano-sized metals, semiconductors, rigid particles and other inorganic particles, fibers, carbon nanotubes and other modifiers as the dispersed phase. The method uniformly disperses the modifier in the matrix material to form a composite system containing nano-sized materials in one phase. Because it has better mechanical properties, barrier properties, thermal stability and flame retardancy than traditional composite materials, it is favored as Widely used in aerospace, national defense, transportation, sports and other fields. [0003] Nanocomposite materials are a new field that develops very rapidly in material science in recent years. The special functions of nanocomposites mainly come from the small size eff...
