Description
One, technical field
The present invention relates to a kind of forced feed lubrication hyperviscosity polymer composites plate squeezing shaped device, belong to the processing and forming field of polymer composite.
Two, background technology
The hyperviscosity polymeric material is meant that polymer molecular weight is far longer than the material of general polymerization thing molecular weight (being generally 20～300,000); As ultra-high molecular weight polyethylene (molecular weight 150～3,500,000) and ultrahigh molecular weight polypropylene (molecular weight＞1,000,000) etc.The high polymeric material of molecular weight has some special nature, and as higher wearability, corrosion resistance, self lubricity, resistance to bond, low temperature resistant and impact resistance etc., therefore, the every field in nation-building and national economy all has been widely used.But because molecular weight is high, the viscosity after the material fusion is high, and melt flow index is minimum, even is zero, so the processing of this class material is very difficult.Past is general adopts the mold pressing base, sinter the single-piece goods into, and the efficient of this production method is very low, cost is high, the costing an arm and a leg of product, and is difficult to the user and accepts.People once added flow ability modifying agent and auxiliary agent in resin, also seek new continuous shaping method and equipment constantly, Chinese patent 93247256 discloses and has been entitled as " plastic reclaimed sheet material extruder head ", this patent is mainly used in the extruder head of plastics mixed type regenerated plates, is actually to be used to extrude a kind of plastics extruding composite board that contains a large amount of wood dusts.This plate squeezing device can not be applicable to the continuously shaped of hyperviscosity polymer at all.
Three, summary of the invention
The objective of the invention is provides a kind of forced feed lubrication to extrude hyperviscosity polymer composites plate squeezing shaped device at the deficiencies in the prior art, during adopt respectively on the sheet material both sides that are characterized in the hyperviscosity polymeric material, the low-viscosity polymeric material is compound and the forced feed lubrication of heatproof lubricating oil, what make composite board extrudes the realization two-forty, and avoids bath surface to break.
Purpose of the present invention is realized by following technical measures:
Forced feed lubrication hyperviscosity polymer composites plate squeezing shaped device is connected to form the major ingredient runner by inner formword (2) and (3), inner formword (2) and (3) outer exterior sheathing (4) and (9) of being connected, during exterior sheathing (4) and inner formword (3) form, low sticking logistics road, exterior sheathing (9) forms lubricated runner with inner formword (2), exterior sheathing (4) forms with (9) and flattens runner, and be extended down to a mouthful mould (12), inner formword is connected with extruder by transition disc (1) with exterior sheathing, exterior sheathing (4) by terminal pad (5) with in, low sticking thing extruder connects, exterior sheathing (9) is connected with lubricating arrangement by medium inlet (11), and inner formword and exterior sheathing are located by bolt, screw connects and composes integral body.
Be provided with heating rod or heater (6), temperature thermocouple (7) in melt flow channel and the exterior sheathing.
A melt flow channel and a mouthful mould are provided with pressure and temperature sensor (10).
Melt flow channel is established damping block and long-pending chute by the cylindrical pancake that flattens in each laminar flow road, make the flowing velocity of outer material comparatively even.
Exterior sheathing is provided with lifting bolt (8).
The present invention has following advantage:
1, can extrude hyperviscosity polymer composite board by continuous high-efficient;
2, avoided the drawback that causes bath surface to break because of the high shear friction;
3, the connection that is applicable to single screw rod, twin-screw or multi-screw extruder is used;
4, can realize multistage temperature control, to satisfy the extruding-out process requirement;
5, charging oral region, sheet material recombination region and die orifice shaping area all can be offered melt temperature and pressure sensor, for the collection research data.
