Polymer material with continuous alternating layered structure and preparation method thereof

Abstract

The invention discloses a method for preparing a polymer material with a continuous alternating layered structure, which comprises the following steps: step 1, mixing 30-70 parts of the first resin or the first resin composite, 70-30 parts of The second resin or the second resin compound is pre-mixed and added to a twin-screw extruder, melted, blended and extruded at a temperature of 100-300 ° C, cooled, and pelletized to obtain blended pellets; step 2, the obtained The blended pellets are subjected to high-speed thin-wall injection molding at an injection temperature of 100-300° C. and an injection speed of 50-1200 mm / s to prepare a polymer material with a continuous alternating layered structure. The whole operation process of the invention is simple, the production cost is low, it is suitable for large-scale industrial production, the thickness of the continuous alternating layered structure can be regulated by adjusting the component distribution ratio of the blend, and it is suitable for various blend systems.

Description

technical field [0001] The invention belongs to the technical field of preparation and multifunctionalization of materials with continuous alternating layered structures, and specifically relates to a method for preparing products of different materials with continuous alternating layered structures through high-speed thin-wall injection molding technology.

With the improvement of people's living standards, higher requirements are put forward for the performance of polymer materials, such as high reinforcement and functionalization of materials. As an important material modification method, polymer blending can not only make up for the lack of performance...

AI Technical Summary

Problems solved by technology

[0006] Although the multi-layer co-extrusion molding process can obtain a good continuous alternating layered structure, and many researchers have carried out a large number of applied research on the continuous alternating layered structure prepared by multi-layer co-extrusion molding, but this molding method is complicated. It takes a long time, so many research results can only stay in the theoretical research stage, and it is difficult to realize industrialization. Therefore, there is an urgent need for a simple and efficient molding method to prepare products with a good alternating layered structure.
