Description
Technical field
The oxymethylene copolymer composition that is used for extending material of the high strength that the present invention relates to be suitable for to form, the ennation of high elastic coefficient by copolyoxymethylenes.In addition, also relate to the extending material that used said composition, structure and preparation method thereof.
Background technology
Ennation in the past with polyolefin resin (as polyethylene, polypropylene etc.), vibrin (as polyethylene terephthalate), polyamide resin (as nylon 6, nylon 6/66 copolymer) study, commercialization.Extensionization about yuban is with a long history, for example can enumerate (with reference to the non-patent literatures 1) such as researchs of the super extension fiber of Clark etc.Yuban generally has degree of crystallinity height, rigidity, intensity, resistance, feature that creep resistant is good.In addition, because crystallization velocity is fast, therefore be widely used in the purposes of mechanism components etc. of automobile, electric installation mainly as the use in injection molding material.And the limit theory intensity of yuban is very high, is hinting by utilizing to extend to carry out crystallographic orientation, can obtain high strength, high elastic coefficient body.
But therefore the degree of crystallinity height of yuban, and very precipitous with the fusing point peak of DSC observation exists fusing point and the shortcoming that be difficult to extend approaching with the crystallization softening temperature.In addition, crystallization velocity is fast, is also causing bigger restriction aspect the extension processing.
In addition, in recent years, as yuban, and resistance, the wear resistance of multipolymer receive publicity, no longer rest in the past injection moulding, extrusion moulding, as extending material, carrying out fiber, and the new purposes exploitation of structure therefrom.Therefore, the raising of no longer rest on and utilize spinning, extending the fiberization techniques of processing is seeking to be used for the raising of the technology of secondary processing.
Known have: the method (with reference to patent documentation 1) of using specific yuban in order to spin, extend processing.This is to use fiber of the slow copolyoxymethylenes of crystallization velocity and preparation method thereof, about adding the additive in the copolyoxymethylenes to, the record of oxidation inhibitor and thermo-stabilizer is only arranged in an embodiment, about its kind and amount, also has its not explanation of influence.
