Embodiment 1

[0035] In the preparation method of Shuangma modified basalt fiber cloth and polyarylene ether nitrile composite material in this embodiment, the basalt fiber cloth is pre-impregnated with a dilute solution of BMI-80 resin (solid-liquid ratio of 1:20), dried, and then dried. Polyarylene ether nitrile resin and 10wt% BMI-80 were blended by solution method (solid-to-liquid ratio of 1:2), impregnated in the treated basalt fiber cloth, and after drying treatment, the basalt fiber cloth was laminated and heated. The prepreg is pressed at a temperature of 260-320 DEG C, and cross-linked and cured at a high temperature to obtain a Shuangma modified basalt fiber cloth and a polyarylene ether nitrile composite material.

Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a bismaleimide modified basalt fiber cloth and polyarylene ether nitrile composite material and a preparation method thereof. The method comprises the following steps: impregnating basalt fiber cloth in a dilute solution of bismaleimide resin in advance, then drying, then blending polyarylene ether nitrile resin and bismaleimide resin through a solution method, impregnating the treated basalt fiber cloth with the obtained blended solution, after drying treatment, carrying out stacking and hot pressing on the basalt fiber cloth, and finally, carrying out hot pressing on the basalt fiber cloth to obtain the composite material. The bismaleimide modified basalt fiber cloth and polyarylene ether nitrile composite material has the remarkable advantages of higher strength, tensile modulus, good heat resistance and the like, and can meet the large-scale application of polyarylene ether nitrile in the field of higher temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a Shuangma modified basalt fiber cloth and a polyarylene ether nitrile composite material and a preparation method thereof. Background technique [0002] Polyarylene ether nitrile is a kind of special thermoplastic resin with nitrile group on the side chain, which has high heat resistance, chemical resistance, radiation resistance, high strength and high modulus, flame retardancy and good creep resistance, etc. Excellent characteristics. It has a wide range of uses in aerospace composite materials, electronic packaging materials and auto parts. [0003] The glass transition temperature of traditional polyarylene ether nitrile is not high enough, and the modulus drops significantly when the application is above the glass transition temperature. 2,2′-bis[4-(4-maleimidophenoxy)phenyl]propane (BMI-80) is a thermosetting resin with excellent mechanical properti...
