Abstract

The invention provides a modified nylon composition and a preparation method thereof, and relates to the technical field of macromolecular materials. The modified nylon composition is prepared from the following raw materials: nylon 6, nylon 66, POE grafted maleic anhydride, polytetrafluoroethylene modified glass fibers, an odor adsorption masterbatch, silicon carbide, a lubricant and an antioxidant. The modified nylon composition has the characteristics of low odor and good wear resistance. The nylon composition prepared by coordinating action of the raw materials has remarkable improvement in wear resistance and keeps excellent mechanical properties, and the forming and processing properties of the material are not affected.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified nylon composition and a preparation method thereof. Background technique [0002] Nylon was developed by an outstanding scientist in the United States, Carothers, and a research team under his leadership. It is the first synthetic fiber to appear in the world. Nylon is a term for polyamide fiber (nylon), which is generally divided into nylon 6 and nylon 66. The appearance of nylon 6 is milky white to light yellow, with toughness, shock resistance, high mechanical strength and heat resistance, good impact strength, high melting point, good molding and processing performance, high water absorption, and saturated water absorption at 11 %, it is easily soluble in sulfuric acid phenols or formic acid, and the low-temperature embrittlement temperature is minus 20 degrees -30 degrees. [0003] Although nylon has many excellent properties, its application will be g...
