Abstract

The invention discloses super-tough nylon. The super-tough nylon is characterized by comprising the following components by weight: 55 to 75 percent of nylon 6, 5 to 15 percent of ultra-fine barium sulfate, 10 to 20 percent of POE-g-MAH, 0.1 to 0.3 percent of antioxidant 1010, 0.2 to 0.5 percent of antioxidant 168, and 0.3 to 0.7 percent of lubricant TAF. A method for preparing the super-tough nylon is characterized by comprising the following steps that the nylon 6 resin, the ultra-fine barium sulfate, the POE-g-MAH, the antioxidant 1010, the antioxidant 168 and the lubricant TAF are mixed well, put into a double-screw extruder, fully melted and compounded in the double-screw extruder, extruded through a nose, pulled into strips, cooled, palletized, dried and packaged. The invention aims to overcome the deficiencies of the prior art and provide the super-tough nylon with low mold shrinkage and good dimensional stability. Another aim of the invention is to provide a method for preparing the super-tough nylon.

Description

technical field [0001] The invention relates to a super-tough nylon, in particular to a super-tough nylon with low molding shrinkage and good dimensional stability, and also relates to a method for preparing the super-tough nylon. Background technique [0002] Polyamide (commonly referred to as nylon) is the base resin with the largest output, the most variety, the widest application and excellent comprehensive performance among the five general-purpose engineering plastics. Nylon has outstanding performance in terms of bending strength, wear resistance, creep resistance, electrical properties, etc., but most nylon varieties are not ideal in low temperature resistance and toughness, so it affects the application in outdoor applications such as railway equipment and auto parts. . [0003] As a major variety of modified nylon, super-tough nylon is mainly prepared by adding rubber elastomer, thermoplastic elastomer, metallocene polyolefin, etc., and blending through a twin-scr...
