Abstract

The invention discloses a plastic profile soft-hard co-extrusion method. The method includes: (1) on a pipeline, employing two extruders, and adding soft and hard plastics respectively; (2) letting the two extruders extrude soft plastic and hard plastic into an FCE mold at the same time respectively to enable bonding in the FCE mold under a high temperature state, controlling the hard plastic at 175DEG C-185DEG C, and controlling the soft plastic at 155DEG C-165DEG C; (3) conducting vacuum pumping, cooling and shaping; (4) drawing the composite profile out of the shaping mold by a tractor; and (5) carrying out fixed-length cutting according to the length requirement. The plastic profile soft-hard co-extrusion method provided by the invention co-extrudes soft-hard plastic profiles together, makes the soft-hard composite profile integrate strength and flexibility to form a light weight and high strength material, and can give full play to the inherent characteristics of various plastics and makes them play a due leading role respectively in the composite profile. According to the method, bonding or lamination is not needed, the efficiency is high and the cost is low.

Description

Plastic material soft-hard coextrusion method
Technical field
The invention belongs to soft or hard material consubstantiality forming processing technology field, particularly relate to a kind of plastic material soft-hard coextrusion method.
Background technology
A lot of commercial production are required for using the material of soft or hard matter consubstantiality, for instance, for sealing and the draw-in groove aluminium section bar of intensity sizing in draw-in groove Combined type air conditioning case body, seal and need to use soft material matter, intensity sizing then needs to use hard material.Existing most of way is that soft or hard bi-material is separated plastics sucking moulding, bi-material is combined into one after molding again, but, the soft or hard material result that this way obtains is bad, and intensity and toughness is low, is unfavorable for the intensity sizing of material.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of plastic material soft-hard coextrusion method, make soft and hard plastic section bar co-extrusion together, soft or hard composite material is made to integrate intensity with elastic, composition light weight, the material that intensity is high, the inherent character of various plastics can be given full play to so that it is in composite material, play respective due mastery reaction;Without cohering or fitting, efficiency is high, and cost is low.
To achieve these goals, the technical scheme is that
A kind of plastic material soft-hard coextrusion method, the processing step of this co-extrusion method is:
(1) on a streamline, two extruders are adopted to be separately added into soft and hard plastic;Wherein one is main extruder, and for duroplasts extruder, described main extruder sets up in the side of streamline, and wherein another is front extruder, for flexible plastic extruder, perpendicular with the direction of streamline;
(2) described main extruder and simultaneously clamp-on in FCE mould simultaneously by duroplasts and flexible plastic respectively for front extruder, so as to bond at high operating temperatures in FCE mould;Described duroplasts controls at 175 DEG C~185 DEG C, and described flexible plastic controls at 155 DEG C~165 DEG C;
(3) on vacuum cooled workbench, extract air in mould, make plastic be close to the die cavity wall of stock mould, take away heat;Cooling water makes mould temperature decline in sizing mold flow simultaneously, product cooling and shaping;
(4) plastic is close to cooler-shaper die wall, by molten state to glass transition, it is pulled out in stock mould with traction machine;Described traction machine motor power (output) is at 2~5 kilowatts, and its pull strength is at 300~500,000 Ns;
(5) Length-fixing cutting is synchronized according to length requirement by cutting machine.
As the improvement to technique scheme, described duroplasts is ABS, HIPS, hard PVC or PP plastics;Described flexible plastic is TUP, TPE, soft pvc plastic.
The plastic material soft-hard coextrusion method of the present invention, make soft and hard plastic section bar co-extrusion together, make soft or hard composite material integrate intensity with elastic, composition light weight, the material that intensity is high, the inherent character of various plastics can be given full play to so that it is in composite material, play respective due mastery reaction;Without cohering or fitting, efficiency is high, and cost is low.
