Description

Technical Field

[0001] The invention relates to the technical field of spinning oils, and in particular to a polyester industrial yarn oil with less white powder loss and a preparation method thereof. Background Art

[0002] Oil is the main auxiliary agent in the production of polyester industrial yarn. It plays a role in adjusting the friction properties of the fiber, preventing or eliminating static electricity accumulation, giving the fiber smoothness, bundling, antistatic, softness and other properties, so that the fiber can smoothly pass through the spinning, stretching, texturing, spinning and weaving processes. Since the production process of polyester industrial yarn has the characteristics of fast spinning speed and high stretching and shaping temperature, the polyester oil is required to have high thermal stability to prevent its high-temperature volatilization from producing smoke, affecting the working environment and the health of operators. In addition, during the polyester spinning process, due to the poor thermal stability of the melt, thermal degradation is prone to occur during the melt extrusion process to produce oligomers. During high-temperature drawing, due to the influence of temperature and stress, the mobility of the molecular chain segments increases, causing some oligomers to migrate from the inside of the fiber to the roller surface to form white powder.

[0003] Patents such as CN1904200A, CN1428480A, CN115896984A, CN106637941A, US4469606, US5525243, and US5972497 all disclose an industrial silk oil with good thermal stability. However, the oil disclosed in the above patents needs to be prepared into an emulsion for use, which consumes a lot of energy. In addition, the crude oil type oil still has a certain volatility and contains heavy metal ions, which are corrosive. The above industrial silk oil is prone to fuzzy silk, broken ends, blue smoke, and hot roller entanglement during spinning.

[0004] CN111206427A discloses a high-temperature oil agent for polyester industrial yarn, which has excellent heat resistance, produces little blue smoke when used, and has excellent spinning performance. However, when the oil agent is used, high-temperature drawing is prone to produce white powder, which is wrapped on the drawing roller, affecting the heat transfer efficiency of the drawing roller, reducing the stretching crystallinity of the fiber, and also greatly affecting the silk path operation, increasing the number of fiber breakage and hairiness. Summary of the invention

[0005] In order to solve the technical problems that the existing polyester industrial yarn oil has poor thermal stability, easy occurrence of lint and broken ends in spinning, blue smoke, poor fiber coating performance, and easy white powder loss on the drafting roller, the present invention provides a polyester industrial yarn oil and a preparation method thereof.

[0006] The technical solution adopted by the present invention is:

[0007] 1. A polyester industrial yarn oil with less white powder loss, composed of the following raw materials in percentage by mass:

[0008]

[0009]

[0010] The purity of the neopentyl polyol isostearate is ≥99%, the acid value is ≤2 mgKOH / g, and the hydroxyl value is ≤5 mgKOH / g.

[0011] Preferably, the preparation method of the neopentyl polyol isostearate is as follows: neopentyl polyol oleate is used as raw material, La or Ce modified SAPO-11 molecular sieve loaded with metal Ni is used as a composite catalyst, and is prepared by one-step hydrogenation isomerization in a fixed bed hydrogenation reactor.

[0012] By adopting the above technical scheme and utilizing the nano-confinement effect of the modified bifunctional catalyst, the raw material oleic acid can be partially isomerized, and at the same time, the Ni active component can catalyze the hydrogenation of the unsaturated double bonds in the raw material, so that the purity of the synthesized neopentyl polyol isostearate is ≥99%, the monoester content is less than 10%, the acid value is ≤2 mgKOH / g, and the hydroxyl value is ≤5 mgKOH / g.

[0013] Preferably, the neopentyl polyol oleate is at least one of neopentyl glycol oleate, pentaerythritol oleate or dipentaerythritol oleate.

[0014] By adopting the above technical scheme, the above raw materials can be used to synthesize neopentyl polyol isostearate in one step under the action of a catalyst, which can greatly improve the oil film strength and antioxidant stability of polyester industrial yarn oil.

[0015] Preferably, the pressure of the hydrogenation reactor is 8-10 MPa, the temperature is 150-180° C., the liquid phase space velocity is 0.1-1.0, and the hydrogen-ester molar ratio is 30-50.

[0016] By adopting the above technical scheme, under the action of high temperature and high pressure and low liquid phase space velocity, the catalyst can function stably and continuously maintain high catalytic activity and selectivity.

[0017] Preferably, the Gemini surfactant is prepared by mixing a sulfonate type anionic Gemini surfactant and a phosphate type anionic Gemini surfactant in a mass ratio of (1-3):1.

[0018] By adopting the above technical scheme, the compound of sulfonate and phosphate salt has good antistatic properties, can effectively conduct and disperse the charge of fiber friction, enhance the cohesion between fibers, and reduce the loss of white powder due to the friction of a single or a few bundles.

[0019] Preferably, the connecting group of the sulfonate type anionic Gemini surfactant and the phosphate type anionic Gemini surfactant is butanediol and / or octanediol.

[0020] By adopting the above technical scheme, the active molecular structure of Gemini surfactant with butanediol and octanediol as connecting groups is compact, and can be arranged closely in the oil system, effectively balancing the oil components, improving the stability of the oil during high-temperature storage and use, and ensuring uniformity of components.

[0021] Preferably, the weight average molecular weight of the polyetheramine dispersant is 1000-1500.

[0022] By adopting the above technical scheme, the polyetheramine with the molecular weight can effectively disperse the oil agent coke produced by combustion or high temperature heating, can disperse the hot roller coke, and reduce the fiber breakage.

[0023] Preferably, the silicone white powder remover is at least one of amino silicone oil, dimethyl silicone oil, and hydrogen silicone oil; the kinematic viscosity of the amino silicone oil, dimethyl silicone oil, or hydrogen silicone oil is 50 to 100 mm 2 / s.

[0024] When the above technical solution is adopted, when crude oil is used directly, the viscosity of the oil agent needs to be controlled. If the viscosity is too small, the hot roller will splash when running at high speed, and if the viscosity is too large, it cannot evenly coat the fiber surface. The silicone material within this kinematic viscosity range has good high-temperature film-forming uniformity and coke-stain stripping performance, and can form a wear-resistant oil film on the surface of the hot roller, which can effectively reduce or prevent the accumulation or residue of white powder or organic coke on the surface of the hot roller.

[0025] Preferably, the stabilizer is a mixture of phosphite, glycerol and water in a mass ratio of (0.5-1.5):(0.5-2.5):1.

[0026] By adopting the above technical solution, phosphite can capture free radicals at high temperature and is an antioxidant, while glycerin has the function of absorbing water and retaining moisture, forming a W / O emulsified system together with water, which helps to stabilize the oil when used at high temperature.

[0027] The method for preparing any one of the above polyester industrial silk oil agents comprises the following steps:

[0028] 1) Add neopentyl polyol isostearate, Gemini surfactant, polyetheramine dispersant, polyetherester emulsifier and white powder remover to the reaction kettle in order according to the ratio, raise the temperature to 40-45° C., and continue stirring for 1-2 hours;

[0029] After stirring, cool to 25-35°C, add stabilizer, and allow to settle naturally for 1-2 hours before filtering, canning, and sealing to obtain the finished product.

[0030] Beneficial effects of the present invention:

[0031] 1. The present application uses neopentyl polyol oleate as a raw material, La or Ce modified SAPO-11 molecular sieve loaded with metal Ni as a catalyst, and one-step hydrogenation isomerization in a hydrogenation reactor to prepare neopentyl polyol isostearate, wherein the purity of the prepared neopentyl polyol isostearate is ≥ 99%, and the monoester content is less than 10%, the acid value is ≤ 2 mgKOH / g, and the hydroxyl value is ≤ 5 mgKOH / g. The use of the neopentyl polyol isostearate as a lubricant enhances the oil film strength and high temperature oxidation resistance of the oil, increases the coating performance of the oil on the fiber, improves the lubricating performance of the oil, reduces the friction coefficient between the fiber and the hot roller, and significantly reduces the white powder generated on the hot roller due to friction.

[0032] 2. The use of Gemini surfactant as an antistatic agent in combination with a polyetheramine dispersant is beneficial to the release of static electricity during fiber friction and the dispersion of organic coke on the surface of the hot roller, thereby further reducing the generation of white powder on the hot roller. In addition, the presence of a double hydrophilic group and a hydrophobic group in the Gemini surfactant helps to disperse the high-viscosity and high-density active components in the oil agent, thereby improving the high-temperature use and storage stability of the oil agent emulsion.

[0033] 3. Use silicone white powder remover to give the fiber a smooth and soft texture and reduce friction; and silicone substances have good lubrication and stripping properties, can adhere to a layer of oil film on the metal surface, have a high-temperature cleaning effect, improve the anti-coking performance of the hot roller, thereby improving the spinning performance, reducing the number of broken yarns and hairy yarns, and greatly improving the production and operation efficiency of polyester industrial yarns.
