Problems solved by technology

[0003] Polyphenylene sulfide fiber is a lightweight high-performance fiber, and its strength retention rate at high temperature is much higher than that of polybutylene terephthalate, polyethersulfone and other fibers. It is mainly used in high-temperature filter materials, although Polyphenylene sulfide fiber has excellent mechanical properties, but its oxidation resistance and water and oil resistance are poor, so it is difficult to apply to occasions with high water content

preparation example Construction

[0023] The present invention provides a method for preparing polyphenylene sulfide fiber with waterproof and oil-proof functions, which comprises the following steps:

[0024] Step one, Fe 3 O 4 / TiO 2 Preparation of particles:

[0025] (1) Fe 3 O 4 For the preparation of particles, add ammonia water dropwise to ferrous sulfate heptahydrate, adjust the pH to 9 in a constant temperature water bath at 35°C to 45°C, stir for 30min to 60min, after the reaction is completed, separate the product with a magnet, wash it with secondary water, and put it in Dry in the drying box to get Fe 3 O 4 Particles, Fe at this time 3 O 4 The particles can be used directly in step (2), or continue to treat Fe 3 O 4 The surface of the particles can be modified by oleic acid. Specifically, the following steps can be used: the prepared Fe 3 O 4 Disperse the particles in secondary water, add appropriate amount of sodium oleate, stir in a water bath at a constant temperature of 50°C for 15-30 minutes, stop s...

Abstract

The invention relates to a production method of waterproof and oil-proof polyphenylene sulfide fibers and belongs to the technical field of new materials.The production method includes the steps of firstly, preparing Fe3O4 / TiO2 particles; secondly, mixing polyphenylene sulfide fiber particles with the Fe3O4 / TiO2 particles; thirdly, performing melt spinning.The production method has the advantages that the waterproof and oil-proof Fe3O4 / TiO2 particles are prepared by the Fe3O4 / TiO2 particles with high surface roughness and using perfluorinated silane or octadecyl silane to perform hydrophobic modification, the waterproof and oil-proof Fe3O4 / TiO2 particles is mixed with the polyphenylene sulfide fiber particles and then subjected to melt spinning to obtain the waterproof and oil-proof polyphenylene sulfide fibers, and detection shows that the waterproof and oil-proof polyphenylene sulfide fibers are excellent in performance and evident in beneficial effect.The invention further provides a polyphenylene sulfide fiber product produced by the method.Compared with polyphenylene sulfide fibers which are not subjected to hydrophobic treatment, the polyphenylene sulfide fiber product has the advantages that the mechanical performance of the polyphenylene sulfide fiber product is basically kept unchanged while the waterproof and oil-proof performance of the polyphenylene sulfide fiber product is increased evidently, and the polyphenylene sulfide fiber product is promising in market prospect.

Description

Technical field [0001] The invention relates to a preparation method of polyphenylene sulfide fiber with water and oil repellent functions. The invention also provides a polyphenylene sulfide fiber product prepared by the preparation method, which belongs to the technical field of new materials. Background technique [0002] In recent years, the superhydrophobic phenomenon on the surface of plant leaves has attracted people's attention. The superhydrophobic ability of the plant is that the leaf surface has significant hydrophobic, desorption, and self-cleaning functions. With the development of science, the design and application of various hydrophobic surfaces has become one of the hot research issues, and various superhydrophobic materials have also emerged. [0003] Polyphenylene sulfide fiber is a lightweight and high-performance fiber. Its strength retention rate at high temperatures is much higher than that of polybutylene terephthalate, polyethersulfone and other fibers. It ...
