A kind of ppo nanocomposite material and preparation method thereof

Abstract

The invention relates to the field of nano composite materials, and in particular relates to a PPO nano composite material. The PPO nano composite material is prepared by performing melt blending on amixed material, wherein the mixed material comprises PPO, and the PPO particles are combined with a nano material and a liquid medium. The invention also relates to a preparation method of the PPO nano composite material. The method comprises the following steps: (1) mixing the nano material and the liquid medium to prepare paste; (2) mixing the paste and the PPO to bond the paste to the surfacesof the PPO particles to obtain the mixed material; and (3) performing melt blending on the mixed material to obtain the nano composite material. According to the method provided by the invention, themixed material does not slip after being added into equipment such as an extruder, the nano composite material can be directly prepared without adding other substances in the preparation process, thenano composite material is convenient for production and processing, the method avoids the problem of poorer performance of a nano composite material caused by too early gasification of a liquid medium in the prior art, and experiments find that compared with the prior art, the nano composite material prepared from the mixed material provided by the invention has more superior performance.

Description

technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a nanocomposite material with PPO as the base material and a preparation method thereof. Background technique [0002] In the existing technology, layered 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 the poor compatibility between layered nanomaterials and polymers, As a result, the impact resistance of such materials is generally not high. [0003] In order to solve the above problems, methods such as intercalation in-situ polymerization are often used to make polymers react between layers of layered nanomaterials to improve the impact resistance of composite materials, but this process is time-consuming and the polymerization conditions are harsh. The solvent is not easy to recycle, which will bring derivative problems such as environmental pollutio...

AI Technical Summary

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
