Problems solved by technology

However, the research on adding montmorillonite to polyether ether ketone for composite modification has not been reported before. If the excellent properties of montmorillonite can be introduced into polyether ether ketone, it will not only further improve the performance of polyetheretherketone, And you can consider adding a large amount to reduce the price of polyether ether ketone

Embodiment 1

[0024] Example 1: Preparation of polyether ether ketone / organized montmorillonite composite material

[0025] First prepare organic montmorillonite: 50 grams of sodium montmorillonite is dispersed in 1000 ml of distilled water, stirred, and left to stand for 24 hours; organically modified in a water bath at 40 ° C, adding monooctadecyl trimethyl Ammonium chloride 55.85 g, stirred for 1 hour using an electric stirring paddle; the product was cooled to room temperature, washed with distilled water until AgNO was added dropwise 3 Until the solution does not precipitate; use a high-speed centrifuge to separate the organic montmorillonite from water, then dry it in an oven at 120° C., crush it, and pass it through a 200-mesh sieve to obtain the organic montmorillonite.

Abstract

The invention belongs to the field of special engineering plastics, in particular to a polyether-ether-ketone / organic montmorillonite composite material and a preparation method thereof. Calculated by the mass, the polyether-ether-ketone / organic montmorillonite composite material is prepared by controlling the temperature in all sections of the charging barrel of a double-screw extruder after changing the addition (1 portion to 20 portions) of the organic montmorillonite with 100 portions of polyether-ether-ketone as reference. The polyether-ether-ketone / organic montmorillonite composite material can have properties, such as higher strength, modulus, the same processing window with polyether-ether-ketone, size stability and the like by adding a small amount of organic montmorillonite (1 portion to 10 portions); in addition, because montmorillonite is natural, the resource is rich and the price is low, a large amount of montmorillonite (15 portions to 20 portions) can be added, so as to reduce the cost of the polyether-ether-ketone composite material and not to affect the use properties.

Description

technical field [0001] The invention belongs to the field of special engineering plastics, and specifically relates to a polyether ether ketone / organized montmorillonite composite material and a preparation method thereof. Background technique [0002] Montmorillonite is an inorganic substance, and the composite material compounded with polymer has the following characteristics: only a small amount of montmorillonite (addition amount is 1 to 10 phr, that is, by mass, every 100 parts of polymer is added 1 ~10 parts of montmorillonite) can make the composite material have higher strength, modulus, thermal stability and dimensional stability. Because montmorillonite exists naturally, has abundant resources and is cheap, this composite material has become one of the hot spots in the field of new materials and functional materials in recent years. In 1987, Okada, the central research institute of Japan's Toyota Corporation, first synthesized nylon 6 / montmorillonite nanocomposite...
