A kind of ABS nanocomposite material and preparation method thereof

Abstract

The invention relates to the field of nano composite materials, in particular to an ABS nano composite material which is prepared by melt blending of a mixed material. The mixed material comprises ABS, and ABS particles are combined with a nano material and a liquid medium. The invention also relates to a preparation method of the ABS nano composite material, and the preparation method comprises the following steps: (1) mixing the nano material and the liquid medium to prepare a paste; (2) mixing the paste and ABS to make the paste stick on the surfaces of ABS particles to prepare the mixed material; and (3) melting and blending the mixed material to prepare the nano composite material. The mixed material cannot slip after being added into equipment such as an extruder and the like, and can be directly used for preparing the nano composite material without adding other substances in the preparation process, production and process are facilitated, and the problem of poor performance ofthe nano composite material caused by premature gasification of liquid mediums in the prior art is avoided. Experiments show that the nano composite material prepared from the mixed material of the invention has more excellent performance compared with the prior art.

Description

technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a nanocomposite material with ABS as a 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 pollution....

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
