Abstract
本发明公开了超高分子量聚乙烯纤维纺丝油剂及其制备方法，属于合成纤维纺丝加工过程中使用的油剂技术领域。本发明以平滑剂，乳化剂，集束剂，防腐杀菌剂，横向尺寸为4‑8μm、碳氧比为（20‑30）：1的单层或多层石墨烯为原料制备了超高分子量聚乙烯纤维用纺丝油剂。石墨烯不仅可以起到抗滴落的作用，而且由于其优异的导电性能，少量添加即可提高纺丝油剂的抗静电性。通过调整石墨烯表面的碳氧比以及尺寸，不仅有利于改善石墨烯在乳液中的分散性，而且可以改善石墨烯本身的力学性能，进而提高油膜强度和润湿速度，不会造成油膜破裂。本发明的油剂适合于规模生产，产品质量稳定，且能够提高纤维成品的性能。The invention discloses an ultra-high molecular weight polyethylene fiber spinning oil and a preparation method thereof, and belongs to the technical field of oils used in the spinning process of synthetic fibers. The invention uses a smoothing agent, an emulsifier, a sizing agent, a preservative and bactericidal agent, and a single-layer or multi-layer graphene with a lateral size of 4-8 μm and a carbon-oxygen ratio of (20-30):1 as raw materials to prepare a spinning oil for ultra-high molecular weight polyethylene fibers. Graphene can not only play an anti-dripping role, but also because of its excellent conductive properties, a small amount of addition can improve the antistatic property of the spinning oil. By adjusting the carbon-oxygen ratio and size of the graphene surface, it is not only beneficial to improve the dispersibility of the graphene in the emulsion, but also can improve the mechanical properties of the graphene itself, thereby improving the oil film strength and wetting speed, and will not cause the oil film to rupture. The oil of the present invention is suitable for large-scale production, has stable product quality, and can improve the performance of the finished fiber product.
Description
Technical Field
The invention relates to the technical field of oiling agents used in the spinning process of synthetic fibers, in particular to an ultra-high molecular weight polyethylene fiber spinning oiling agent and a preparation method thereof.
Background
The spinning oil is used as an intermediate medium in the process of converting textile raw materials into textiles, and has the function of ensuring smooth production of chemical fibers, and the adhesion rate of the oil on the fibers is not more than 0.3% -0.5%, but has an important role in the processes of fiber production, spinning and weaving. Meanwhile, with the development of new technologies for high-speed spinning equipment and fibers worldwide, oiling agents have become an indispensable important part in fiber production technology. In the process of spinning fiber, the use of chemical fiber oiling agent is indispensable, and the chemical fiber oiling agent can adjust the friction characteristic of the fiber, prevent or eliminate static accumulation, endow the fiber with the characteristics of smoothness, softness and the like, ensure that the chemical fiber smoothly passes through the processes of spinning, stretching, elastic spinning, weaving and the like, and ensure the smooth production of chemical fiber. The oiling agent on the surface of the fiber is firstly contacted with production equipment, and under the condition of determining the raw materials and the production process, the preparation of the oiling agent has obvious influence on the production cost, the production efficiency and the product quality. Therefore, the method has great value in research and application.
The ultra-high molecular weight polyethylene fiber, also called as high-strength high-modulus polyethylene fiber, is a high-performance fiber which is successfully developed in the last 70 th century and enters industrialization in the early 80 th, and is also called as three high-tech fiber in the world today. It is a fiber spun from ultra-high molecular weight polyethylene with molecular weight of 100-500 ten thousand, and is one of the fibers with highest specific strength and specific modulus in the world. The most attractive characteristics of ultra-high molecular weight polyethylene fibers are: light weight, high strength and high modulus. In addition, the fiber has the excellent performances of low temperature resistance, impact resistance, abrasion resistance, ultraviolet radiation resistance, high specific energy absorption, low dielectric constant, high electromagnetic wave projection rate, low friction coefficient, outstanding impact resistance, cutting resistance and the like. Because the ultra-high molecular weight polyethylene fiber has a plurality of excellent characteristics, the fiber is extremely interesting and important for a plurality of countries once the fiber is brought out, so that the ultra-high molecular weight polyethylene fiber shows extremely great advantages in the high-performance fiber market, and plays a very important role in the fields of modern war, aviation, aerospace, national defense equipment and the like.
Although ultra-high molecular weight polyethylene fibers have such many advantages, spin finishes specifically used for ultra-high molecular weight polyethylene fibers are very few. On the one hand, polyethylene is composed of highly crystalline bodies which are orderly arranged, and has few polar groups, so that the conductivity is extremely poor in the fiber spinning process, and static electricity cannot be conducted; on the other hand, the polyethylene macromolecule long chain has no hydrophilic group, so the moisture absorption rate is extremely small, the wetting of spinning oil is not facilitated, the oil film strength is low, and the spinning is difficult.
Disclosure of Invention
In view of the above problems, the invention provides the ultra-high molecular weight polyethylene fiber spinning oil agent for overcoming the above problems and the preparation method thereof, and the prepared ultra-high molecular weight polyethylene fiber spinning oil agent has the characteristics of static resistance, high stability, good wettability and the like, can be well adsorbed on the surface of the fiber, is rapidly oiled, forms a good protective film, and endows the ultra-high molecular weight polyethylene fiber with good friction performance and good static resistance and smoothness.
The aim of the invention is achieved by the following technical scheme.
In a first aspect, the invention provides an ultra-high molecular weight polyethylene fiber spinning oil, which comprises the following components in parts by weight:
50-60 parts of a smoothing agent, 15-20 parts of an emulsifying agent, 5-10 parts of a bundling agent, 1-4 parts of an antiseptic bactericide and 2-10 parts of graphene; wherein the graphene is single-layer or multi-layer graphene, and the transverse dimension is 4-8 mu m; the carbon-oxygen ratio is (20-30): 1.
In previous work, the inventors have employed graphene oxide as an additive to aramid spin finish. However, graphene oxide is highly polar and unsuitable for use as an additive to ultra-high molecular weight polyethylene fiber spin finishes. In addition, graphene oxide has low mechanical properties due to the existence of a plurality of defect groups, which is unfavorable for improving the oil film strength. According to the invention, graphene is adopted as an additive of the ultra-high molecular weight polyethylene fiber spinning oil, has excellent wear resistance, can be used as an oil film reinforcing agent, and plays a role in increasing the oil film strength.
In order to improve the antistatic property of the oil, various antistatic agents are added in the prior art. Common antistatic agents include anionic antistatic agents and cationic antistatic agents. However, these antistatic agents, although having excellent antistatic properties, tend to drip and tend to rust metals and yellow fibers. According to the invention, graphene is adopted as an additive of the ultra-high molecular weight polyethylene fiber spinning oil, and the graphene is in a lamellar structure, so that not only can the anti-dripping effect be achieved, but also the antistatic property of the spinning oil can be improved by adding a small amount of graphene due to the excellent conductive property. The prior art with publication number CN108547149A, CN115434044A and the like mentions that graphene is used as an antistatic agent of spinning oil, however, the graphene is modified, the influence of the performance of the graphene on the oil is not recognized, the preparation process is complex, and the lifting effect is limited. The inventors found that the lateral dimension of graphene was 4-8 μm; the carbon-oxygen ratio is (20-30): 1 can improve the antistatic property and the wetting property of the spinning oil. The graphene cannot be too small in size, the graphene is easy to agglomerate due to the too small size, and the anti-dripping effect cannot be achieved; meanwhile, the graphene is easy to settle and uneven in dispersion due to oversized size.

Table 3: comparative example 1-comparative example 4 results of the performance test of the ultra high molecular weight polyethylene fiber spin finish
As can be seen from examples 1-13, the present invention was carried out with a transverse dimension of 4-8 μm and a carbon to oxygen ratio of (20-30): and 1, preparing the spinning oil for the ultra-high molecular weight polyethylene fiber by taking the monolayer graphene as a raw material. The graphene not only can play a role in resisting dripping, but also can greatly improve the antistatic property of the spinning oil by adding a small amount due to the excellent conductive property. By adjusting the carbon-oxygen ratio and the size of the surface of the graphene, the graphene is modified without adding a coupling agent, so that the dispersibility of the graphene in the emulsion is improved, the mechanical property of the graphene can be improved, the strength and the wetting speed of an oil film are improved, and the oil film is not broken. It should be noted that the amount of graphene should not be too large, otherwise agglomeration phenomenon is easy to occur, and the strength and wettability of the spinning oil are affected. The sorbitan monooleate and the dodecyl phosphate monoester with different electronegativity are compounded, so that the dispersion performance of graphene can be effectively improved, and the improvement of the performance of the spinning oil is facilitated. Comparative examples 1-4 demonstrate that graphene undersize is prone to cause agglomeration of graphene; and the size is oversized, graphene is easy to settle, and emulsion stability is poor. When the carbon-oxygen ratio of the graphene is too large, the surface active groups are fewer, the balance of hydrophilic-hydrophobic interfaces cannot be formed, and the dispersion of the graphene in the spinning oil is affected; when the carbon-oxygen ratio is too small, active groups are too many, so that the performance of graphene is easily reduced, the affinity with polyethylene fibers is reduced, and the performance of the spinning oil is not improved.
