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 nano composite materials and in particular to a thermoplastic vulcanized rubber nano composite material and a preparation method thereof. The nano composite material is prepared from a premix through melting blending, wherein the premix is prepared from a nano material which is combined with a liquid medium and is adhered to thermoplastic vulcanized rubber granules and fills space among the thermoplastic vulcanized rubber granules; and the thermoplastic vulcanized rubber granules comprise nonpolar granules and polar granules. The preparation method comprises the following steps: mixing the liquid medium with the nano material so as to obtain an ointment, pasting the ointment to surfaces of the thermoplastic vulcanized rubber granules, and carrying outmelting blending, so as to obtain the nano composite material. The nano composite material provided by the invention has excellent toughness, and in addition is short in process, low in cost and applicable to popularization and application.

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 between the layers of nanomaterials to improve the impact resistance of the composite material. However, 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 environmen...
