Problems solved by technology

However, the glass fiber reinforced nylon material has low fracture deflection and poor flexibility, which limits its application range.
At present, there are few reports on the research on the high deflection and flexibility modification of reinforced nylon materials. By improving the deflection and flexibility of reinforced nylon materials, the application range of reinforced nylon materials can be further expanded, which is very important for the development of reinforced nylon materials.

preparation example Construction

[0049] In a specific embodiment, the preparation method of the highly flexible flexible reinforced nylon material of the present invention comprises the following steps:

[0050] Nylon resin, compatibilizer, antioxidant, lubricant, softener (solid) are mixed evenly; The mixed material is added in the twin-screw extruder, and glass fiber, softener ( Liquid state) is introduced from the side feed port of the twin-screw extruder, and the extruded material is cooled in a water tank, air-dried, and pelletized to obtain a high-deflection flexible reinforced nylon material.

[0051] Among them, there are two ways to add the softener: the first is to mix the solid softener with nylon resin, compatibilizer, antioxidant and lubricant evenly, add it to the twin-screw extruder, and then melt and extrude Blended with fiberglass. The second is to use a liquid pump to add the liquid softener from the side feed port of the twin-screw extruder, mix it with the melt-extruded nylon resin, compa...

Abstract

The invention discloses a high-deflection flexible reinforced nylon material and a preparation method thereof. The high-deflection flexible reinforced nylon material is mainly prepared from, by weight, 45-85 parts of a nylon resin, 10-50 parts of reinforcing fibers, 0.2-5 parts of a softener, 2-8 parts of a compatilizer, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant; and the softenercomprises at least one of modified silicone oil or a surfactant, and the compatilizer comprises a maleic anhydride grafted polymer. The deflection and the flexibility of the reinforced nylon materialare obviously improved on the basis of keeping high mechanical strength of a conventional reinforced nylon material. The defects of low deflection and poor flexibility of the reinforced nylon materialare overcome, and the application range of the reinforced nylon material is expanded.
