Abstract
The invention discloses a low-temperature-resistant ultra-toughness modified nylon alloy material and a preparation method thereof. The low-temperature-resistant ultra-toughness modified nylon alloy material is prepared from the following raw materials: PA (poly A) 66, PA6, a main flexibilizer, an auxiliary flexibilizer, a compatilizer, a main ultraviolet absorption agent, an auxiliary ultraviolet absorption agent, a main antioxidant, an auxiliary antioxidant and a lubricating agent. The preparation method comprises the following steps of: mixing the raw materials in a high mixing machine uniformly; putting the mixture into a dual-screw extrusion pelletizer for heating and fusing, vacuumizing, slicing and pelletizing; drying materials after pelletization in a vacuum box, so as to obtain the product granulate low-temperature-resistant ultra-toughness modified nylon alloy material provided by the invention. The product low-temperature-resistant ultra-toughness modified PA66 alloy material provided by the invention has high comprehensive performances and excellent temperature-resistant performance, achieves the advanced level of similar products abroad, can replace imported materials, and meets the high-quality requirement of the domestic market on the ultra-toughness PA66 alloy.
Description
technical field [0001] The invention relates to a nylon alloy material and a preparation method thereof, in particular to a low-temperature resistant super-tough modified nylon alloy material and a preparation method thereof. Background technique [0002] As a widely used engineering plastic, nylon (polyamide) is flexible, wear-resistant and has high mechanical strength. At the same time, polyamide (PA) is a crystalline high polymer, which will have a sharp yield point when it is subjected to tensile stress, and the stress will gradually increase with the increase of strain after passing the yield point. Therefore, if unmodified nylon is used in certain fields, its ductility, notched impact strength and low temperature toughness need to be modified. [0003] The existing nylon toughening modification methods mainly include the following: 1) Copolymerization with other lactams or amino acids; 2) Toughening with rubber or elastomer components; 3) Core-shell polymers Tougheni...
