Description
Technical field
The present invention relates to the technology of preparing of PPS fiber, be specially a kind of preparation method with self-extinguishment and the PPS fiber without molten drop.The method utilizes oxidant to be sulfone (SO by polyphenylene sulfide fibre surface sulphur atom (S) partial oxidation
2), the PPS fiber of the selective oxidation of generation has without molten drop and creep resisting feature.
Background technology
Polyphenylene sulfide (be called for short PPS) be with phenyl ring to on link sulphur atom and the stiff backbone that formed, owing to there being the existence of a large amount of π key in structure, so its performance is more stable.The maximum feature of PPS fiber is exactly Long-Time Service under higher temperatures and extremely severe working environment, is mainly used in heat filtering material.Along with the development of high-tech research and application, people have higher requirement to exotic material.The serviceability temperature of PPS fiber is about 180 DEG C, and the exhaust temperature of plant emissions often reaches 190-220 DEG C, and under this hot environment, fibres show creep causes web contraction, and causes PPS fibrous mechanical property to reduce and life-span minimizing.PPS belongs to middle high section filtering material, and not resistance to oxidation, exploitation PPS is the high temperature resistant of matrix and oxidation resistant fiber, makes its high temperature resistant grade section of reaching a high temperature, can at 280-300 DEG C of Long-Time Service.Because PPS vitrification point and fusing point are not very high, cause this kind of easy creep of fiber and easy molten drop, if the vitrification point of MODIFIED PP S is brought up to more than 300 DEG C, the preparation without molten drop and the PPS high-temperature fibre without creep will be realized completely.This modified fibre can be widely used as protective articles, as fire-entry suit, stokehold Work Clothes, electric welding Work Clothes, special uniform, fireproof felt, fire screen and fireproof glove etc.
While maintenance PPS its excellent properties, tackle it and carry out structure and composition carries out modification.Blended is make up PPS defect the most effectively and one of the simplest method.By the mode of modification, overcome the above-mentioned shortcoming of PPS fiber, improve the combination property of PPS fiber.The copolymers such as usual employing polyamide, polyolefin, polytetrafluoroethylene (PTFE) carry out co-blended spinning, and in PPS resin, add the stuffing such as calcium carbonate, nano imvite, CNT, silica or organo-mineral complexing antioxidant carry out modification to PPS fiber.Compared with PPS fiber, PPS/SiO
2fibrous mechanical property improves, and heat resisting temperature can improve 50 DEG C.On the other hand, due to SiO
2/ PPS fiber increases at the post crystallization degree that is heated, and make PPS aggregated structure more stable, therefore its percent thermal shrinkage significantly reduces.PPS fiber surface modification is also the important means promoting its performance; PTFE dispersion liquid is applied in the Final finishing of PPS filtrate; PTFE is formed on fiber coating; filtrate is played a protective role; intercept the infringement of oxidisability and corrosive goods confrontation filtrate, improve the performance of filtrate, make filtrate have better filter efficiency; more easy-to-clean ash, and increase the service life.Sol-gel process is utilized to be coated with on the surface of conventional PPS fiber with SiO
2, SiC, BN and TiO
2be the protective layer of main body Deng ceramic material, effectively can extend the service time of fiber under high-temperature oxygen-enriched condition, can further improve fire-retardant, acidproof, the resistance to oxidation of fiber and the performance such as high temperature resistant.In addition, plasma processing techniques is utilized also can to carry out surface modification to PPS fiber.But current method of modifying technique is more complicated, difficult control, and cost is also relatively high, is unfavorable for that industrialization is produced.
