Problems solved by technology

However, as a high-performance fiber for special purposes, PBO is only sold in Europe, America and Japan as a munitions product. It is banned in my country and the price is also very expensive. Therefore, my country has been conducting independent research and development of PBO.

Embodiment 1

[0022] The two-component smoothing agent of 45% mass fraction (the mineral oil of 25% mass fraction, the isomeric octaol fatty acid ester of 20% mass fraction) and the adjuster triol propionate of 10% mass fraction are mixed and stirred to 120 ℃, stirred for 1h, cooled to 75°C, and then added a three-component emulsifier (10% mass fraction of polyoxyethylene sorbitan ester, 15% mass fraction of C 16 Alcohol polyoxyethylene ether, 10% mass fraction of polyethylene glycol synthetic ester) and 10% mass fraction of antistatic agent (5% mass fraction of C 6 Alkyl phosphate potassium salt, 5% mass fraction of metulin derivative type), add into the reaction kettle, stir for 2 hours, cool to 60°C, filter, discharge, and pack to obtain the product.

Embodiment 2

[0024] The two-component smoothing agent of 50% mass fraction (the vegetable oil of 25% mass fraction, the isomeric octaol fatty acid ester of 20% mass fraction, the animal oil of 5% mass fraction) and the regulator dipropionic acid of 8% mass fraction The pentaerythyl alcohol ester was mixed and stirred to 125°C, stirred for 1h, cooled to 85°C, and then added a three-component emulsifier (10% mass fraction of sorbitol monooleate, 15% mass fraction of C 14 Alcohol polyoxyethylene ether, 7% mass fraction of polyethylene glycol synthetic ester) and 10% mass fraction of antistatic agent (7% mass fraction of C 8 Alkyl phosphate potassium salt, 3% mass fraction of C 8 Alkylbenzene sulfonate), add to the reaction kettle, stir for 1.5h, cool to 55°C, filter, discharge, and pack.

Embodiment 3

[0026] The two-component smoothing agent of 50% mass fraction (the vegetable oil of 20% mass fraction, the isomeric tridecyl alcohol fatty acid ester of 30% mass fraction) and the modifier pentaerythyl dipropionate of 5% mass fraction are mixed and stirred to 120°C, stirred for 1h, cooled to 80°C, and then added a three-component emulsifier (10% mass fraction of sorbitol monooleate, 15% mass fraction of C 16 Alcohol polyoxyethylene ether, 10% mass fraction of C 18 Fatty alcohol polyoxyethylene polyoxypropylene ether) and 10% mass fraction of antistatic agent (6% mass fraction of C 12 Alkyl phosphate potassium salt, 4% mass fraction of C 28 Alkylbenzene sulfonate), added to the reaction kettle, stirred for 1 hour, cooled to 57°C, filtered, discharged, and packaged.

Abstract

The invention discloses a poly-p-phenylene benzobisoxazole fiber spinning oil agent and a preparation method thereof. The spinning oil agent is prepared from the following compound raw materials including, by mass, 5%-15% of an antistatic agent, 35%-50% of a smoothing agent, 25%-40% of an emulsifier and 5%-10% of a regulator, wherein the sum of the percents by mass of the components is 100%. The preparation method comprises the following steps of adding the smoothing agent and the regulator into a reaction kettle, heating to 115-125 DEG C, uniformly stirring, cooling to 75-85 DEG C, adding theemulsifier and the antistatic agent into the reaction kettle, uniformly stirring, cooling to 40-60 DEG C, and filtering to obtain the spinning oil agent. The poly-p-phenylene benzobisoxazole fiber spinning oil agent obtained by the invention has excellent performance, is suitable for spinning production of PBO, can endow fibers with appropriate antistatic property, smoothness, wear resistance, washability and the like, and completely meets the requirements of upstream production and downstream manufacturing processes.

Description

technical field [0001] The invention relates to the field of auxiliary agent manufacturing in synthetic fiber processing, in particular to a poly-p-phenylenebenzobisoxazole fiber spinning oil and a preparation method thereof. Background technique [0002] Polyparaphenylene benzobisoxazole (PBO) is a linear polyaromatic liquid crystal polymer molecule. PBO was originally a reinforced material developed by the U.S. Air Force Laboratory in the 1980s as a composite material with high temperature resistance. The strength, modulus, heat resistance and flame resistance of its fibers, especially the PBO fiber It is a superfiber of the 21st century, whose strength exceeds that of steel fibers, even surpassing that of carbon fibers. However, due to the limitation of the synthesis process, it is impossible to synthesize large molecular weight PBO polymers, and its superior performance cannot be reflected. With the continuous advancement of technology, it was not until October 1998 tha...
