Abstract

The invention discloses a high-gloss, high-fluidity and high-content glass fiber reinforced nylon material and a preparation method thereof. The high-content glass fiber reinforced nylon 6 composite is prepared from branched nylon 6 resin, glass fiber, an antioxidant and a brightening lubricant. According to the high-content glass fiber reinforced nylon 6 composite, the nylon 6 resin is completely infiltrated in the glass fiber, so that the nylon material has high fluidity and high surface gloss, can replace metals, and can also be used for producing ultra-thin and complicatedly designed shells of mechano-electronic and auto parts.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-gloss, high-fluidity, high-content glass fiber reinforced nylon 6 composite material and a preparation method thereof. Background technique [0002] As an excellent engineering plastic, nylon material has excellent mechanical properties such as tensile properties, bending properties, and compressive strength, as well as excellent low temperature properties, stable chemical properties, good mechanical properties, superior electrical insulation properties, small specific gravity, and easy processing. Forming, self-extinguishing, good wear resistance, widely used in automobiles, electronic appliances, chemicals, mechanical instruments, construction and other industries. However, it has high water absorption, poor acid resistance, low dry and low temperature impact strength, and easy deformation after water absorption, which affects the dimensional stabi...
