Problems solved by technology

The preparation method is simple and the production cost is low, but this method is to add montmorillonite mud after polyamide melting, which will cause the montmorillonite mud to be completely mixed with the copolymer in the future, and the water between the layers will be gasified due to high temperature. As a result, the polyamide failed to enter the interlayer in time. At the same time, the energy generated only by water vaporization was not enough to completely peel off the montmorillonite layer, so a completely peeled composite material could not be obtained, and its product performance was greatly affected. influences

Abstract

The invention relates to the field of nanocomposite materials, in particular to a thermoplastic vulcanizate nanocomposite material and a preparation method thereof, wherein the nanocomposite material is prepared by melt blending a premixed material, and the premixed material is prepared from The nanometer material combined with the liquid medium is filled and adhered between thermoplastic vulcanized rubber particles, and the thermoplastic vulcanized rubber includes polar plastics and non-polar rubbers. The preparation method comprises mixing the liquid medium and the nano material to obtain a paste, adhering the paste to the surface of thermoplastic vulcanized rubber particles for melting and blending to obtain a nanocomposite material. The nanocomposite material provided by the invention has excellent toughness, short technological process and low cost, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a thermoplastic vulcanizate nanocomposite material and a preparation method thereof. Background technique [0002] In the existing technology, nanomaterials and polymers are often mixed and extruded to form composite materials. Although the tensile strength of such composite materials has been improved, due to problems such as poor compatibility between nanomaterials and polymers, this type of material The impact resistance performance is generally not high. [0003] In order to solve the above problems, methods such as intercalation in-situ polymerization are often used to make the polymer react in the gaps of nanomaterials to improve the impact resistance of the composite material, but this process takes a long time, the polymerization reaction conditions are harsh, and the solvent is not easy. Recycling will bring derivative problems such as environmental pollution. ...
