Abstract

The invention provides a low-cost and high-performance glass fiber reinforced nylon 6 composite material and a preparation method thereof. The composite material comprises the following components in percentage by weight: 57%-82.5% of nylon 6, 3%-20% of compatibilizing and toughening agents, 3%-12% of calcium sulfate whiskers, 0.1%-0.5% of nucleating agents, 0.1%-0.5% of main antioxidants, 0.1%-0.3% of auxiliary antioxidants, 0.3%-1.7% of modified assistants, 0.2%-0.7% of silicon oil and 5%-25% of glass fiber. The preparation method of the composite material comprises the following steps of: firstly mixing nylon 6 and silicon oil in a high-speed mixer, sequentially adding whiskers, nucleating agents, antioxidants, modified assistants and compatibilizing and toughening agents, uniformly mixing, and then melting, extruding and pelleting the mixture with glass fiber in a combined double-screw extruder, wherein the extrusion temperature is 240-260 DEG C. The glass fiber reinforced nylon 6 composite material has the advantages of low cost, excellent mechanical property, good fluidity, smooth surface and the like and can be used for devices with higher surface requirements, such as microwave ovens, electric tool panels and the like.

Description

technical field [0001] The invention relates to a nylon material and a preparation method thereof, in particular to a glass fiber reinforced nylon material and a preparation method thereof. Background technique [0002] After nylon 6 is reinforced with glass fibers, its mechanical properties, thermal properties, dimensional stability, creep resistance, fatigue resistance and wear resistance have all been significantly improved. Since the development of long glass fiber reinforced nylon 6 in the early 1970s, its application range has been further broadened. Long glass fiber reinforced nylon 6 composite materials have great development potential in the fields of automobiles, machinery, electrical appliances, and military industry. They can be used to manufacture automobile bumpers, engine noise isolation covers, seat frames, headlights, fans, radiator grilles, Dashboard brackets, etc., and also occupy a place in the fields of aerospace and weapons. [0003] How to reduce cos...
