Antistatic bacteriostatic ultra-high molecular weight polyethylene fiber and preparation method thereof

Abstract

The invention belongs to the technical field of ultra-high molecular weight polyethylene fibers, and particularly relates to an antistatic antibacterial ultra-high molecular weight polyethylene fiber. The antistatic antibacterial ultra-high molecular weight polyethylene fiber is composed of the following components of, in parts by weight, 100-200 parts of ultra-high molecular weight polyethylene, 1-3 parts of an antioxidant, 3-5 parts of an antistatic agent, 20-50 parts of an antibacterial agent, 1-10 parts of a macromolecular compatilizer, 0.2-1.4 parts of a coupling agent, 4-8 parts of a surfactant, 0.1-1 part of a synergist and 450-1,000 parts of a solvent. According to the antistatic bacteriostatic ultra-high molecular weight polyethylene fiber and the preparation method thereof, a reasonable formula is selected, and all the components have a synergistic effect, so that the overall performance of the UHMWPE fiber is effectively improved, particularly, the UHMWPE fiber has stronger antistatic and antibacterial properties, excellent mechanical properties of the material can be maintained, the stability is high, the service life of the UHMWPE fiber is prolonged, and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of ultra-high molecular weight polyethylene fibers, and in particular relates to an antistatic and antibacterial ultra-high molecular weight polyethylene fiber and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fibers have the characteristics of high strength, high modulus, and high thermal conductivity, and are irreplaceable in many fields. It is pioneering to produce a UHMWPE fiber with antibacterial function, which can enrich the performance and function of UHMWPE fiber and expand the application of UHMWPE fiber in civil fabrics, medical equipment and other fields. [0003] UHMWPE fiber has low surface energy and surface tension, high crystallinity, and extremely smooth surface. It is difficult to effectively combine with commonly used inorganic and organic antibacterial agents, which makes post-treatment methods such as padding and coating an...

Problems solved by technology

However, the low-molecular antistatic agent used in this method gradually precipitates from the surface of the product over time, and the antistatic performance of the material is gradually reduced until lost. The instability of the antistatic performance of the product in the practical process is safe. Hidden dangers of production

[0005] CN106589582A discloses a kind of reinforced and toughened antibacterial polypropylene material and its production method, which adopts nano zinc oxide or titanium dioxide as inorganic antibacterial agent, and then polypropylene, ultra-high molecular weight polyethylene masterbatch, inorganic antibacterial agent, grafted polypropylene and other additives are melted and extruded through a twin-screw extruder to obtain reinforced and toughened antibacterial polypropylene materials. However, when the method is applied to the production of ultra-high molecular weight polyethylene (UHMWPE) fibers, the antibacterial rate is greatly reduced, and the impact on fracture Both the strength and the initial modulus have a negative effect, and the TiO 2 It has antibacterial effect only when it is excited by ultraviolet light, and has no antibacterial ability under other conditions

First of all, the antibacterial rate of the above-mentioned obtained materials is not an ideal effect, which limits its application in the field of medicine, and because its inorganic antibacterial agent molecules are small, the migration speed of inorganic particles is large, and it is easy to be lost from the material to further reduce Its antibacterial rate; secondly, without describing the mechanical properties and antistatic effect of the product, it is difficult to comment on its practicability as a material
