Description

Technical Field

[0001] The invention belongs to the technical field of spinning oils, and particularly relates to a highly stable antistatic crude oil type spinning oil and a preparation method thereof. Background Art

[0002] As the textile industry accelerates its move towards high value-added and functional fields, the fiber material system has shown unprecedented diversified innovation vitality. A series of differentiated varieties such as regenerated cellulose fiber, ultra-fine denier fiber, bio-based fiber and high-performance synthetic fiber have emerged like mushrooms after rain. These new fibers have their own characteristics in performance, which greatly enriches the types and application scenarios of textile products. However, their emergence also puts forward almost harsh process requirements for spinning processing technology. As a core auxiliary agent that is crucial in the spinning process, spinning oil is facing severe challenges: on the one hand, in the high-temperature environment of high-speed spinning, spinning oil needs to have excellent anti-coking performance. High temperature will cause oxidation, polymerization and other reactions of certain components in the oil. If the anti-coking property is insufficient, coking deposits will easily form. These deposits will not only cause a sharp increase in the local friction between the fiber and the equipment components, but also cause damage to the fiber surface and quality degradation in severe cases, and even cause production accidents such as broken ends and broken wires, greatly affecting production efficiency and product quality. For example, in some high-speed spinning production lines, due to the poor anti-coking property of the oil, obvious coking will occur in key parts of the equipment after several hours of operation, requiring frequent shutdowns for cleaning, which seriously restricts the production progress. On the other hand, the formula of the spinning oil also needs to be precisely controlled in view of the unique interface characteristics of different fibers. Due to the significant differences in the chemical composition, surface morphology and physical properties of different fibers, this requires the oil to optimize the anti-splashing performance while strengthening the anti-static property.

[0003] Chinese patent document CN117845379B discloses a process for preparing a highly efficient antistatic agent for chemical fiber oil, which combines the prepared nitrogen-sulfur doped Mxene with an antistatic agent to obtain a new antistatic agent. The chemical fiber oil prepared by using the antistatic agent has an electrical conductivity of about 0.775~0.988mS / cm. Although the patent introduces Mxene material into the antistatic agent, which improves the antistatic performance of the oil to a certain extent, the overall performance of the oil has not achieved a qualitative leap. On the one hand, in terms of anti-coking performance, the patented technology has not been effectively improved and optimized, and cannot meet the strict requirements for the anti-coking performance of the oil under high-speed spinning and high-temperature conditions. On the other hand, the patent has not proposed a comprehensive and systematic solution to the adaptability of different fiber interface characteristics, and it is difficult to optimize the anti-splashing performance while ensuring that the tow is tightly bundled and has no broken ends and looseness during the spinning process.

[0004] In summary, there is still an urgent need for a solution that can improve the overall performance of spinning finish. Summary of the Invention

[0005] The object of the present invention is to provide a highly stable antistatic crude oil-based spinning finish and its preparation method. Using alkyl-modified titanium carbide as the core component can not only improve the antistatic property of the highly stable antistatic crude oil-based spinning finish and reduce the total amount of antistatic components used, but also enhance the stability of the antistatic property of the spinning finish, thereby comprehensively improving the performance of the highly stable antistatic crude oil-based spinning finish.

[0006] To achieve the above object, the present technical solution provides a highly stable antistatic crude oil-based spinning finish, including: a smoothing agent, an emulsifier, an antistatic agent, a bundling agent, and a wetting agent, wherein the antistatic agent includes alkyl-modified titanium carbide sheets.

[0007] In some embodiments, the antistatic agent additionally includes one or a combination of sodium dodecyl sulfate and sodium dodecyl sulfonate.

[0008] In some embodiments, the mass content of the antistatic agent is 6-8 wt%.

[0009] This solution particularly selects alkyl-modified titanium carbide sheets as the core component of the antistatic agent. The alkyl-modified titanium carbide sheets are titanium carbide sheets with surface alkylation modification. The alkyl-modified titanium carbide sheets have a two-dimensional sheet structure and belong to a kind of alkyl-capped sheet Mxene. As the core component of the spinning finish, the alkyl-modified titanium carbide sheets in this solution can effectively enhance the overall performance of the spinning finish, including the antistatic property and stability of the spinning finish.

[0010] Furthermore, the alkyl-modified titanium carbide sheets in this solution are Ti3C2T x sheets with octyltriethoxysilane on the surface. Octyltriethoxysilane reacts with the hydroxyl groups on the surface of the titanium carbide sheets through a silane coupling agent. Due to the alkylation modification with octyltriethoxysilane in this solution, the antistatic property of the alkyl-modified titanium carbide sheets is further improved.

[0011] Specifically, the preparation method of the alkyl-modified titanium carbide sheets is as follows: S1: Prepare a titanium carbide slurry; Add LiF to the HCl solution and stir well in an ice bath to obtain a mixed solution. Slowly pour Ti3AlC2 into the mixed solution and react at 35°C - 40°C for 12 - 48 h to obtain an acidic solution. Repeatedly wash the acidic solution with deionized water by centrifugation until the pH of the supernatant is about 6 - 6.5, and exfoliate Ti3C2T through the oscillation operation during centrifugation xSheet; S2: Alkyl-modified titanium carbide sheet: Replace the water solvent of the Ti3C2Tx sheet with acetone by centrifugation and prepare a dispersion. Place the dispersion under an inert atmosphere and ultrasonicate to obtain a monolayer of Ti3C2T x acetone suspension. Add octyltriethoxysilane to the acetone suspension of monolayer Ti3C2T x and stir at room temperature for 6 - 96 h. After centrifugally washing the unreacted octyltriethoxysilane with acetone, an alkyl-modified titanium carbide sheet is obtained.

[0012] In some specific embodiments, Add 1 - 2 parts of LiF to 1 - 2 parts of HCl solution and stir well in an ice bath for 30 min to obtain a mixed solution. Slowly pour 0.05 - 0.5 parts of Ti3AlC2 into the mixed solution and react at 35°C - 40°C for 12 - 48 h to obtain an acidic solution. At this time, the Al layer is etched. Then, repeatedly wash the acidic solution with deionized water by centrifugation until the pH of the supernatant is about 6 - 6.5, and exfoliate the Ti3C2Tx sheet by oscillating during centrifugation; Disperse 0.5 - 5 g of Ti3C2T x sheets (40 wt.%) by centrifugally replacing the water solvent with acetone to prepare a 20 - 30 mL dispersion. Place the dispersion under an inert atmosphere and ultrasonicate to obtain a monolayer of Ti3C2T x acetone suspension. Add 0.5 - 5 mL of octyltriethoxysilane to the acetone suspension of monolayer Ti3C2T x and stir at room temperature for 6 - 96 h. After centrifugally washing the unreacted octyltriethoxysilane with acetone, an alkyl-modified titanium carbide sheet is obtained.

[0013] There are many advantages to using alkyl-modified titanium carbide sheets in this solution: On the one hand, it makes the spinning finish have a good anti-coking rate: In traditional spinning finishes, phosphate ester antistatic agents are often used (including the octanol phosphate salt, octanol polyoxyethylene ether phosphate salt, and dodecyl phosphate salt mentioned in the nitrogen and sulfur-doped Mxene antistatic agent in the above background). They are prone to generating coking deposits at the hot rollers during spinning processing, affecting the stability of spinning processing. In this solution, titanium carbide sheets are used as the core component of the antistatic agent, and the other antistatic agent components are selected from one or a combination of sodium dodecyl sulfate and sodium dodecyl sulfonate, without phosphate ester antistatic agents. Therefore, it can avoid the adverse effects caused by phosphate esters and improve the product quality rate.

[0014] On the other hand, the antistatic property of the spinning finish is significantly improved: Since the alkyl-modified titanium carbide sheet has a two-dimensional sheet structure, a continuous conductive network can be formed in the spinning finish. This structural feature greatly enhances the overall conductivity of the spinning finish. High conductivity means that only a small amount of antistatic agent is needed to achieve the target antistatic property, so the amount of antistatic agent can be significantly reduced.

[0015] Furthermore, the antistatic stability of the spinning finish is greatly improved: Since the original polar functional groups (such as -OH) on the surface of the titanium carbide sheet can reduce the direct contact with environmental oxygen / moisture and inhibit oxidative degradation, the lifespan of the antistatic agent can be extended from the material itself. However, the nitrogen and sulfur-doped MXene mentioned in the background art is prone to oxidation or hydrolysis during long-term use due to the exposure of surface active sites. In addition, the alkyl chain further imparts hydrophobicity to the titanium carbide sheet, reducing hygroscopicity and making the conductivity mainly depend on the self-conductive network of the titanium carbide sheet rather than environmental humidity, which also makes the antistatic performance more stable. Moreover, the alkyl chain protects the surface of the titanium carbide sheet from oxidation or hydrolysis (especially in a humid and hot environment), maintaining long-term conductivity, and thus also improving the chemical stability of the spinning finish. In addition, the MXene sheet is stably dispersed in the spinning finish and is not easily aggregated due to mechanical shear or temperature changes, ensuring the durability of the conductive network.

[0016] In some embodiments, the spinning finish contains 40 - 55 wt% of a smoothing agent, and the smoothing agent is white oil.

[0017] In some embodiments, the spinning finish contains 15 - 19 wt% of an emulsifier, and the emulsifier is one or a combination of isotridecyl polyoxyethylene ether and sorbitan fatty acid ester.

[0018] In some embodiments, the spinning finish further contains 10 - 15 wt% of a wetting agent, and the wetting agent is fatty alcohol polyoxyethylene ether.

[0019] In some embodiments, the spinning finish further contains 7 - 10 wt% of a bundling agent, and the bundling agent is composed of a compound of polyethylene glycol 400 oleate and isotridecyl polyoxyethylene polyoxypropylene ether, specifically 3 - 5:1 - 1.5.

[0020] In some embodiments, the spinning finish further contains 3 - 5 wt% of an anti-coking agent, and the anti-coking agent is a fatty acid methyl ester ethoxylate double-capped surfactant.

[0021] In some embodiments, the water content in the spinning finish does not exceed 4 wt%.

[0022] In some embodiments, the total mass of each component in the spinning finish is 100 wt%.

[0023] In a second aspect, the present solution provides a method for preparing a highly stable antistatic crude oil-based spinning finish, comprising the following steps: While stirring and adding materials simultaneously, a smoothing agent, an emulsifier, an antistatic agent, a bundling agent, and a wetting agent are successively added into a reaction kettle. The antistatic agent includes alkyl-modified titanium carbide lamellae. The reaction temperature is set at 55-65 °C, the reaction rotation speed is 400-600 r / min, and the reaction time is 30-40 min.

[0024] For the content same as above in the embodiments of this preparation method, it will not be repeated here.

[0025] Compared with the prior art, the present technical solution has the following characteristics and beneficial effects: (1) The highly stable antistatic crude oil-based spinning finish of the present invention uses alkyl-modified titanium carbide lamellae as the core component of the antistatic agent, which can effectively avoid and reduce the problem that the commonly used phosphorus-based antistatic agent components containing salt are prone to coking at high temperatures.

[0026] (2) As a highly conductive lamellar material, alkyl-modified titanium carbide lamellae can greatly improve the conductivity of the spinning finish and effectively reduce the total dosage of the antistatic agent components.

[0027] (3) The antistatic agent used in the spinning finish of the present invention can significantly improve the stability of the antistatic performance of the spinning finish, making its antistatic performance not easily fluctuate due to environmental influence. Specific Embodiments
