Description
Technical field
The present invention relates to a kind of immersion system, particularly relate to a kind of string immersion system; The application also relates to the method using this string immersion system to carry out natural plant fibre impregnated with molten resin, and the string impregnated with molten resin tooth material obtained by the method.
Background technology
Be subject to the restriction of natural fiber form, natural fiber enhancing thermoplastic polymer composite material mainly short fiber (fibre length 0.2-0.4mm) strengthens thermoplastic polymer composite material, just mixed fiber and material are first added banbury or double screw extruder mixing granulation by main preparation technology, after through injection moulding, extrude or mould pressing process moulded products, because granulation process fiber shortens by screw rod shearing, resulting product intensity is affected, and is difficult to meet structural strength demand.
Last century Mo, international composite markets has emerged in large numbers long fiber reinforcement thermoplastic polymer, LFRT (the Long Fiber Reinforced Thermoplastic) pellet namely usually said, wherein fibre length is between 3-10mm, and the mechanical property of composite is stepped a stage.
Application number be 201210251939.6 Chinese patent application disclose a kind of natural fiber and strengthen thermoplastic resin unidirectional prepreg tape and preparation method thereof, be characterized in first natural fiber and thermoplastic resin fibre being carded to strip-shaped product, rear warm-up mill is pressed into natural fiber/thermoplastic resin unidirectional prepreg tape.Although such an approach achieves the preparation of the vast of heaven right fiber prepreg stain material, this technique needs first thermoplastic resin to be processed into threadiness, and process is loaded down with trivial details and the Homogeneous phase mixing that will realize natural fiber and resin fibre has larger difficulty.
Application number be 201210315906.3 Chinese patent application disclose a kind of continuous-filament woven fabric and strengthen thermoplas tic resin composite and preparation method thereof, the method first natural fiber or inorfil is made continuous-filament woven fabric, after fibrofelt surface spoon the good plastics of fusion plastification, make resin wetting fibre felt through the roll-in of biobelt roll squeezer.Although the method can prepare the right fiber reinforced thermolplastic composite material of the vast of heaven, but this technique needs natural fiber to make continuous-filament woven fabric, and it is closely knit to arrange between fiber, affect the effect of impregnation of resin to fiber, and this technique is only suitable for preparing sheet products.
At present, the industrial production of LFRT pre-preg material is based on melt impregnation.Melt impregnation does the comparatively conventional a kind of dipping method of fiber glass reinforcement, usually be matrix with thermoplastic polymer and adopt screw extruder to be connected with immersion system, Polymeric melt inlet runner and long fibre access road are orthogonal or at an angle in same plane.Its technical process is that continuous fiber tow is imported a dipping die head under tension force traction, in order to improve dispersion and the dipping effect of continuous fiber, generally need arrange the devices such as jockey pulley in immersion system or continuous fiber drawing-in device.Zigzag arrangement pressed by jockey pulley, and continuous fiber is subject to tension force effect when wriggling and walking around these jockey pulleys and is dispersed into monofilament, thus ensures that every root fiber fully can be infiltrated by thermoplastic melt.Such as application number be 200910193484.5 Chinese patent application disclose a kind of long fiber reinforced plastics production fibre bundle fuse dipping die head and dipping method, except the dip roll of zigzag arrangement, this inventive features is that employing has medium-altitude contact godet and noncontact godet pair, reinforced plastics melt is toward the Radial Flow of fibre bundle, the friction decreasing fibre single thread is lost, and makes the stable operation under high impregnated wire speed of the melt impregnation of continuous fiber tow.Although melt impregnation procedure is simple, and dipping effect is good, but continuous fiber needs to walk around the dip roll by zigzag arrangement up and down in melt impregnation preparation process, fiber needs to bear larger tension force, so it is continuous that melt impregnation equipment disclosed is at present applicable to single fiber more, the fibre bundle melt impregnation that tenacity is higher, such as glass fibre and carbon fiber, and for single discontinuous natural plant fibre bar melt impregnation, if ribbon is not twisted, easy generation fibre bundle phenomenon of rupture, and ribbon tenacity improves after twisting, although meet the requirement of melt impregnation, fibre dense after twisting, easily there is shredded dried bean curd line phenomenon in dipping effect difference, so current disclosed melt impregnation equipment be not suitable for natural fiber.
