preparation example Construction

[0032] So, the present invention provides a kind of preparation method of continuous glass fiber / nylon flat belt, comprising:

[0033] Melting and kneading the nylon resin antioxidant to obtain a melt;

[0034] The melt and continuous glass fiber are extruded through a die head, drawn, pressed and wound to obtain a continuous glass fiber reinforced nylon flat belt.

[0035] The continuous glass fiber reinforced nylon flat belt is braided to obtain a continuous glass fiber reinforced nylon sheet.

[0036] The continuous glass fiber reinforced nylon sheet is laminated, heated and molded to obtain a continuous glass fiber reinforced nylon composite sheet.

[0037] According to the present invention, the melting temperature of the nylon resin is 240-260°C, and a twin-screw extruder is used for melting and kneading. The flat tape is braided into a thin plate, and then the thin plates are stacked and hot-pressed at 200-250°C to obtain a composite plate.

[0038] The continuous gl...

Abstract

The invention provides a preparation method of continuous glass fiber / nylon composite and the application of the continuous glass fiber / nylon composite at the aspects of the aerospace, the military industry, vehicles, architecture, furniture and the like. High-flow nylon and mixture of the high-flow nylon serve as basic materials, continuous glass fibers serve as reinforcing materials, antioxidants and the like are added at the same time, and the novel thermoplastic composite is prepared. The continuous glass fiber / nylon composite has the advantages of high strength and high gloss, is ideal substitute materials for steel materials, and can be used for preparing components such as a cover plate of a car engine, a cover plate of a trunk, a building template, furniture plates, and a framework of a seat chair.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a continuous glass fiber / nylon composite material and its preparation method and application. Background technique [0002] Due to the need for energy conservation and environmental protection, components in industries such as automobiles, electronics, and mechanical equipment are developing towards lightweight and miniaturization, and more and more metal materials are gradually being replaced by polymer composite materials. At present, most of the thermosetting polymer composite materials used have poor impact resistance and are not recyclable, while thermoplastic composite materials based on PP have low rigidity, poor wear resistance and weather resistance, and insufficient heat resistance, which limit their application range. . Therefore, the development of other thermoplastic composite materials with high strength, high modulus, light specific gravity, we...
