Abstract
The invention discloses a super-tough nylon alloy, which is characterized by comprising raw material by weight percent: 65-90% of nylon, 10-35% of itaconic acid grafting ethylene-alpha-octylene copolymer (POE-g-ITA), 0.1-1% of antioxygen, 0.2-1% of lubricating agent, TAF. A method for preparing the super-tough nylon alloy is characterized by comprising the following steps: placing all raw material into a high mixer and mixing the raw materials for 5-10min; then placing the mixed raw materials into a double screw extrusion machine for extrusion and pelleting; carrying out traction, cooling and grain-sized dicing, finally drying the grain material; wherein main engine speed is 200-400r / min, temperature is 250-280 DEG C. The invention aims to prepare a novel super-tough nylon material which can be widely applied to the fields such as automobiles, electric products, office appliances and constructional engineering.
Description
technical field [0001] The invention relates to a super-tough nylon alloy and a preparation method thereof, in particular to a method for preparing super-tough nylon by grafting polyolefin elastomer with itaconic acid, which can be applied to the fields of automobiles, electronic appliances, office appliances, construction engineering, etc. The invention belongs to the technical field of engineering plastic modification. Background technique [0002] Polyamide (commonly called nylon) is one of the engineering materials with the largest output, the most varieties, the widest application and excellent comprehensive performance among the five general-purpose engineering plastics. It can be widely used in automobiles, electronic appliances, office appliances, construction projects, etc. . Nylon has outstanding performance in terms of bending strength, wear resistance, creep resistance, electrical properties, etc., but most nylon varieties have poor impact resistance, especially...
