Modified poly (phthalazinone ether sulfone ketone) resin, microporous material and preparation methods thereof

Abstract

The invention provides modified poly (phthalazinone ether sulfone ketone) resin which is prepared from PPESK resin, PPS resin and ground glass fibers. The invention also provides a preparation method of the modified poly (phthalazinone ether sulfone ketone) resin. The preparation method comprises the following steps: step 1, mixing materials; and step 2, loading the premixed material obtained in the step 1 into a twin screw for granulation through melt extrusion, and conducting cooling and pelleting. The invention also provides a preparation method of a modified poly (phthalazinone ether sulfone ketone) microporous material, and further claims to protect the modified poly (phthalazinone ether sulfone ketone) microporous material. The modified poly (phthalazinone ether sulfone ketone) microporous material inherits the excellent properties of resin and simultaneously endows the material with a special porous structure, the apparent density is reduced by nearly 30% compared with a solid material with the same components, and the preparation method is an effective method for realizing light weight of material and greatly enlarges the range of application of the PPESK resin.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified phthalazinone structure polyaryl ether sulfone ketone resin, a modified phthalazinone structure polyaryl ether sulfone ketone microporous material and a preparation method. Background technique [0002] Microcellular foamed material refers to the cell density range of 10 9 ~10 15 piece / cm 3 Among them, a new type of material with a cell size (1 to 2 orders of magnitude smaller than traditional foam materials) ranging from 0.1 to 10 μm. This concept was first proposed by Professor Suh of the Department of Mechanical Engineering of the Massachusetts Institute of Technology (MIT), and has been intensively studied in the past two decades. Compared with unfoamed materials, the unique structure of microcellular foamed materials makes them have excellent performance in terms of impact strength, toughness and fatigue resistance, high thermal stability, low dielect...

AI Technical Summary

Problems solved by technology

However, although PPESK has excellent comprehensive performance, its melt viscosity is too high, conventional thermoforming processing is difficult, and it is impossible to directly use supercritical fluid microporous injection molding (Mucell) for foaming, which seriously restricts its use as a microporous material.
