Description
Technical field
The invention belongs to the preparation method of polyurethane elastomeric fiber, in particular to a kind of compound elastic polyurethane of low cost
The preparation method of fiber.
Background technique
In recent years, spandex entire industry in China's showed the apparent situation that supply exceed demand, and product profitability is significantly
Decline.In order to cope with increasingly serious competition situation, many enterprises introduce high-speed spinning, multiple head spinning etc. by eliminating the backward production facilities
Advanced technologies equipment achievees the purpose that improving production efficiency, save the cost.In addition, also there is relevant report from reduction spandex former material
Expect that the exploitation of cost direction has the spandex product of cost advantage.
Reduce spandex production the cost of raw material method can there are two types of: it is a kind of be exactly with cheap domestic raw material instead of into
Mouth raw material.This technological means is simple and easy, is used by most of domestic spandex company.But now spandex body material is basic
It has domesticized, only a small amount of function additive is using imported product, therefore effect of this method for reduction spandex cost
It is very little.Another method is exactly to use lower other raw material replacement spandex conventional raw material of cost.Spandex is conventional
Body material is polytetramethylene ether diol (PTMG) and 4,4 '~methyl diphenylene diisocyanate (MDI), wherein PTMG institute
The ratio accounted for is about 80%.So seek price have more advantage polymer diol replace PTMG be once developing low-cost
The research hotspot of spandex.Arco Chemical Technology, Inc, the U.S. (CN1239971A) just applied for that disclosure used low saturation in 1999
Polypropylene glycol (PPG) partially replace PTMG prepare spandex.But by the spandex of this method preparation in elasticity modulus, permanent deformation
Rate etc. all has apparent gap with original product.The U.S. has cost advantage because Vesta AG & Co. OHG applied using in 2006
Poly- (tetramethylene~copolymerization~ethyleneether) glycol prepare the patent of invention (CN101313004A) of spandex.By the technology system
Standby product elongation, in terms of have an improvement, but key performance (such as breaking strength) is obviously deteriorated.These are poly-
The principal status of public economy of the PTMG in spandex production can not be replaced by closing object glycol so far, it is only possible to be obtained in certain functionalization spandexs
A small amount of application.
The also another technical method for reducing the cost of raw material in fact, is exactly so-called physics completion method.Physics filling
Refer under the premise of not weakening polymer original performance, other kinds of polymer or inorganic particle added into polymer,
To reach the purpose of polymer modification, cost declining.Although this technical method plastics or rubber processing be it is a kind of compared with
Conventional technology, but the patent or document report mistake not any so far in spandex production field.Its reason may be just like
Lower several points: one, spandex will have a direct impact on spandex as a kind of strong flexible polymer fiber, the addition of common low cost polymer
The formation of two-phase laminated flow structure deteriorates the high resiliency of spandex；Two, the production of spandex mostly uses greatly solution-polymerized SBR or melt spinning skill
Art, the filling of a large amount of inorganic unmodified powders, not only will have a direct impact on the mobility and fibre forming property of polymer, but also make spandex
Production stability is by large effect.The present invention is the spandex new product that preparation has cost advantage, uses high resiliency for the first time
Polymer and modified inorganic powder carry out physics filling to spandex.
