Description

Technical Field

[0001] The invention relates to the technical field of composite material preparation, in particular to an antibacterial modified nylon elastomer composite material and a preparation device and method thereof. Background Art

[0002] Antimicrobial modified nylon elastomer composite material is a new type of material that combines the high strength of nylon and the flexibility of elastomer with the addition of antimicrobial agents. This material is commonly used in the manufacture of medical devices, sports equipment, automotive interiors and other products to improve the durability and hygiene of the products.

[0003] In the prior art, it is difficult to pre-treat the antimicrobial agent when preparing the antimicrobial modified nylon elastomer composite material, which may make it difficult to disperse the antimicrobial agent in the nylon elastomer when it is added to the extruder later, reducing the utilization rate and antimicrobial effect of the antimicrobial agent. At the same time, it is difficult to improve the processing performance of the composite material, which makes it difficult to process it into the required shape and size later. In the prior art, it is difficult to adjust the temperature when pre-treating the antimicrobial agent, which may cause the plasticizer to volatilize, reduce the chemical reaction between the plasticizer and the antimicrobial agent, and the stability of the antimicrobial agent, and increase its decomposition and loss during storage and use. In addition, since abnormal pressure changes may cause bubbles, cracks or other defects in the composite material during the extrusion process, it is difficult to detect the pressure of the extruder with existing technology. When the pressure fluctuates abnormally, the extrusion process is stopped in time, which reduces the yield rate of the composite material. At the same time, the screw, barrel and other key components inside the extruder may be deformed, worn or even broken due to overload; Finally: When cutting antibacterial modified nylon elastomer composite materials, it is difficult to adjust the cutting pressure in the existing technology, which may cause the composite material to be subjected to excessive stress during the cutting process, increase the damage, deformation and difficulty of subsequent processing of the composite material, and reduce the dimensional accuracy and surface quality of the composite material; and some equipment is difficult to check the sharpness of the blade, which makes it difficult for the staff to adjust the cutting speed according to the actual situation in the later stage and optimize the entire cutting process. At the same time, it is difficult to replace the blunt blade in time according to the sharpness of the blade, which increases the frequency of blade replacement and increases production costs.
