Example Embodiment

[0044] Example 1

[0045] The polymer composite material with oriented filler comprises a polymer matrix filled with a filler with shape anisotropy. In this embodiment, the polymer matrix is ​​polyvinyl alcohol (PVA) with a molecular weight of about 7000, and the filler is Na-type montmorillonite. The material composed of polyvinyl alcohol (PVA) and Na-type montmorillonite is prepared into a composite material by a layer-multiplier extrusion method of segmentation-restacking and confluence, and the anisotropic filler is oriented in the material flow during the preparation.

[0046] The preparation method of the polymer composite material with oriented filler includes:

[0047] Preliminary steps: Put an appropriate amount of montmorillonite powder into deionized water, then vigorously stir for a period of time (for example, two weeks), then let it stand, and then collect the supernatant after the rest. PVA was slowly added to 80°C deionized water, and dissolved under vigorous stirri...

[0050] Example 2

[0051] The polymer composite material with oriented filler adopts a dual structure, that is, two different materials are laminated and then extruded. It includes two polymer matrices, and the first polymer matrix is ​​filled with a shape-anisotropic filler. In this embodiment, the first polymer matrix is ​​polycarbonate (PC), the second polymer matrix is ​​polyethylene terephthalate (PET), and both PC and PET are commercially available products. . The polycarbonate (PC) is filled with a filler. The filler is talc.

[0056] The polymer composite material with oriented filler comprises a polymer matrix filled with a filler with shape anisotropy. In this embodiment, the polymer matrix is ​​nylon 6, the filler is organic montmorillonite, and the organic montmorillonite is a clay modified by intercalation of 12 amino acids and 12 acids. The material composed of nylon 6 and organic montmorillonite is prepared into a composite material by a layer-multiplier extrusion method of segmentation-restacking and confluence. During the preparation, the shape anisotropic filler is oriented in the material stream.

Abstract

The invention discloses a polymer composite material with oriented padding and a preparation method thereof. The polymer composite material comprises at least one polymer substrate and is characterized in that at least one of the polymer substrates is filled with at least one padding with shape anisotropy; the material composition comprising raw materials of the polymer substrates and the padding with shape anisotropy is prepared into the composite material by a layer multiplying and extruding method by cutting and then superposing and accumulating; and in the process of preparation, the padding with shape anisotropy obtains orientation in material flows. In the invention, the operation of adding the padding with shape anisotropy into the substrate and the layer multiplying operation are combined together, and the padding with shape anisotropy gradually obtains orientation when the material is continuously cut and then superposed and accumulated, so that the material is prepared into the polymer composite material with the oriented padding, thereby solving the problems of low efficiency, difficult control, high requirements and the like existing in the background art.

Description

technical field [0001] The present invention relates to the field of polymer processing, more particularly, to polymer composite materials containing shape-anisotropic fillers capable of orientation and a preparation method thereof. Background technique [0002] With the development of composite material technology, the application fields of composite materials have become wider and wider, and the usage has also been greatly increased. A good example is that the two most advanced airliners in the world, Airbus's A380 and Boeing's Dream 787, both use composite materials extensively. Composites for the fuselage and wings of these airliners account for an unprecedented proportion of about 50 percent of the aircraft's total weight. Because composite materials are generally light and easy to process and form into various shapes and structures, not only can the weight of the aircraft be greatly reduced, but also the aerodynamics can be greatly improved. Composite materials, espe...
