Description
Technical field
This patent relates to a kind of process units of macromolecular material, the process units when especially two kinds of different material form macromolecular materials being mixed.
Background technology
The hybrid mode of macromolecular material mainly contains direct mixing at present, different phase in screw rod extruded material process adopts the mode that charge door is set to mix, these hybrid modes all are in the solid-state mixing of carrying out down at material, perhaps having a kind of material at least is the mixing of carrying out down solid-state, two kinds or more of generally speaking material outward appearances relatively near the time, these several hybrid modes just can reach the mixing needs, but when the material form difference that needs to mix is big, such hybrid mode just is difficult to reach requirement, mix such as a kind of pulverulent macromolecular material needs and a kind of graininess macromolecular material, both particle diameters differ bigger, the two kinds of macromolecular materials of product that adopt such hybrid mode to obtain just can not reach good mixing and disperse uniformly, and the defective of this mixing can cause the defective of properties of product and the instability of product quality.And the process units of employing this patent, make pulverous macromolecular material in different screw rods, carry out fusion in advance with granular macromolecular material, macromolecular material to two kinds of fusions mixes then, so just can make two kinds of macromolecular materials reach sufficient mixing and evenly dispersion, thereby guarantee product quality.In addition, a side of the main extruder when side feeding position is chosen in powder and has just reached molten condition, the macromolecular material that is beneficial to these two kinds of different material states reaches the longest with the molten condition incorporation time.
The compound extruding technology of a kind of rubber processing is disclosed in the article " hot feeding extruding production line " of " world rubber industry " magazine (the 29th volume first phase) of publishing in calendar year 2001, a kind of use of hot-feed extruder is disclosed in this technology, it is that several extruders are connected with composite machine head simultaneously, pass through different runner extruded materials with several extruders, extrude simultaneously by several materials of composite machine head, to reach the compound purpose of extruding.This technology is just extruded jointly at one of head section, and several material material do not mix mutually through screw rod, and final product neither good mixing and the uniform product that disperses.The utility model mainly is in order to make two or more different macromolecular materials just begin to mix when just being in molten condition, make it reach good mixing and dispersion uniformly, therefore fusion side feeding production technology of the present utility model is that material mixes through side feed screw fusion and at main-machine screw fusion start-up portion, through main-machine screw further part mixing dispersion.The utility model is different with the technological means that above public technology is taked, and the purpose that reaches is also different.
In U.S. Pat 5749649A, a kind of extrusion equipment is disclosed, this equipment mainly comprises a main extruder, at dynamic mixer of the terminal connection of main extruder, head of the terminal connection of dynamic mixer, on dynamic mixer, there are one or several to import point, link to each other with an auxiliary extruder with rigid connector or flexible connecting member at the importing point.This equipment is when extruded material, and the principal goods material is extruded through main extruder, enters dynamic mixer then, mixes blender with the auxiliary agent that enters from auxiliary extruder, finally extrudes by head.This equipment is in order to solve the interpolation problem of labile auxiliary agent.And the utility model is to extrude the direct side of introducing the master to feed, and is different with the purpose of above-mentioned invention disclosed, and the technological means of employing is also different.
Among the U.S. Pat 20030214067A1, disclose a kind of extrusion equipment, this equipment mainly comprises two extruders, main extruder and auxilliary extruder.At first extruder adds organic filler (wood-fibred), and organic filler is removed moisture in the material, air and volatile part through main extruder, then with in auxilliary extruder the polymer of heating and melting mix, extrude by main extruder at last.The main extruder of this invention is to have moisture, air or volatile part in the organic filler in order to remove, and mixes with the polymer of auxilliary extruder fusion in the position near head then.And the utility model main extruder adopts double screw extruder, and its screw configuration mainly is applicable to fusion, dispersion and the mixing of Powdered macromolecular material; The side feeding adopts double screw extruder equally, and its screw configuration is applicable to fusion, the conveying of graininess macromolecular material, and is different with the purpose of above-mentioned invention disclosed.In addition, auxilliary extruder main extruder to add the implantation site also different, its position must add the particle macromolecular material of carrying through the fusion of side feeding at the spiro rod section that the driving screw material just reach molten condition, this technological means with above-mentioned disclosed employing is different.
The utility model content
The purpose of this utility model is when solving two kinds of different shape macromolecular materials and mixing, and mixes, disperses inhomogeneous, causes product quality defect, and the problem of unstable properties provides a kind of melt polymer material side feeding process units.
The technical solution adopted in the utility model is: a kind of melt polymer material side feeding process units, to form by main extruder and side feed extruder, and main extruder and side feeding machine top are drawing-in device, connect main-machine screw in the main extruder.
Form by a main extruder and one or many side feed extruders.
The fusion side feeding position of this process units is provided with 2 * 96/96 big helical pitches and carries screwing element.
The beneficial effects of the utility model are: the macromolecular material of the different shape that mixes by this patent, and two kinds or several macromolecular material are fully mixed, fine dispersion, the properties of product of production are stable.
