Abstract

The invention relates to an antibacterial PA66/ABS composite material. The antibacterial PA66/ABS composite material is mainly prepared through blending the following ingredients in parts by mass and carrying out melting: 50-70 parts of polyhexamethylene adipamide, 10-30 parts of processing activator, 30-50 parts of acrylonitrile-butadiene-styrene, 5-10 parts of compatibilizer, 5-20 parts of toughener, 0.1-0.3 part of diffusion oil, 0.6-1.5 parts of antibacterial agent and 0.2-2 parts of auxiliaries. The antibacterial PA66/ABS composite material is prepared through firstly, thoroughly mixing weighed polyhexamethylene adipamide, weighed processing activator, weighed acrylonitrile-butadiene-styrene, weighed compatibilizer and weighed diffusion oil in a high-speed mixer, then, adding the antibacterial agent and the auxiliaries into the mixture, and finally, adding the toughener into the mixture and carrying out thorough mixing, so as to obtain a premix; carrying out melt extrusion on the premix through a twin-screw extruder, and carrying out drawing, cooling and pelleting. The product provided by the invention has the advantages of easiness in processing, high antibacterial performance, excellent mechanical properties, and the like.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic engineering plastics and its preparation, and in particular relates to an antibacterial nylon composite material and a preparation method thereof. Background technique [0002] Polyhexamethylene adipamide, commonly known as nylon 66 (PA66), is a thermoplastic engineering plastic widely used in automobiles, electronics, machinery and other fields. It has excellent wear resistance, impact resistance and self-lubricating properties. It is resistant to chemicals, but it is not resistant to strong alkali, and has high water absorption and creep. These shortcomings limit its application to a large extent. The PA66 / ABS composite material prepared by blending and modifying PA66 with acrylonitrile-butadiene-styrene (ABS) not only has the wear resistance, impact resistance and self-lubricating properties of nylon, but also has the toughness of ABS And rigidity, in addition to better surface matte eff...
