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 present invention relates to the field of nano composite materials, and in particular relates to a thermoplastic vulcanized rubber nano composite material and a preparation method thereof. The nano composite material is obtained by performing melt blending on a pre-mixed material, wherein the pre-mixed material is formed by packing and bonding a nano material combined with a liquid medium to thermoplastic vulcanized rubber particles, and the thermoplastic vulcanized rubber comprises a polar plastic and polar rubber. The preparation method comprises the steps of mixing the liquid medium andthe nano material to obtain paste, bonding the paste to the surfaces of the thermoplastic vulcanized rubber particles, and performing melt blending to obtain the nano composite material. The nano composite material provided by the invention has excellent toughness, a short process flow and low costs, and is suitable for promotion and use.

Description

technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a thermoplastic vulcanized rubber 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 pollutio...
