High polymer material is also referred to as polymeric material, is, using high-molecular compound as matrix, then (to help equipped with other additives
Agent) material that is constituted.Applied in high polymer material relatively broad is thermoplastic elastomer (TPE), thermoplastic elastomer (TPE) TPE/
TPR, also known as artificial rubber or synthetic rubber.Its product had both possessed the high resiliency of traditional cross-linking vulcanized rubber, ageing-resistant, oil resistivity
Every excellent properties, while but also with the characteristics of common plasticses are easy to process, processing mode is wide.Can be using injection, extrusion, blowing
Deng processing mode production, 100% directly secondary uses after mouth of a river corner is crushed.Both simplify process, processing cost reduced again,
Therefore Latest Materials of the thermoplastic elastomer (TPE) TPE/TPR materials as the traditional rubber of substitution, its environmentally friendly, nontoxic, comfortable feel,
Exquisite appearance, makes product more intention.Therefore it is also more hommization, a high-grade novel synthetic material, is also the world
Change standard environment-friendly materials.
Thermoplastic elastomer (TPE) is a kind of novel high polymer material between rubber and resin, can not only replace part
Rubber, moreover it is possible to be modified plastics.Rubber and the dual property of plastics and the characteristic of broadness that thermoplastic elastomer (TPE) has,
Be allowed to be widely used in rubber industry the everyday articles such as manufacture rubber overshoes, adhesive plaster and sebific duct, adhesive tape, adhesive tape, offset plate, glue part and
The various industrial goods such as adhesive.Meanwhile, it is general that thermoplastic elastomer (TPE) can also replace rubber to be largely used in PVC, PE, PP, PS etc.
The thermoplastic resin even modification of the engineering plastics such as PU, PA, CA above, make plastics industry also occur in that brand-new situation.
The common thermoplastic elastomer (TPE) of in the market is:Styrene analog thermoplastic elastomer (SBC), polyolefins thermoplastic bullet
Property body (TPO), thermoplastic polyurethane (TPU), polyester-type thermoplastic elastomer (TPEE), polyamide-type thermoplastic elastomer
(TPAE) is in these elastomers, and each elastomer has different performance wherein, styrene analog thermoplastic elastomer bag
The styrenic elastomer that SBS and SEBS.SEBS is hydrogenation is included, the saturation degree of its strand is higher, therefore, SEBS heatproof
Property, weather resisteant, UV resistance etc. will be significantly better than SBS elastomers, in being thermoplastic elastomer (TPE), most widely used one kind.
The production equipment of elastomer common at present is double screw extruder, and double screw extruder is to rotate production by screw rod
Raw pressure and shearing force so that material can fully be plastified and uniformly mixed the material processing of merga pass mouth mold shaping
Equipment.In twin screw extrusion, because the structure of screw rod is different, the pressure and shearing force produced by its rotation are different,
Have an impact to the gelation degree and the uniformity of material, how material plasticizing is obtained evenly at present, be those skilled in the art
Urgent problem to be solved.
Utility model content
In summary, the utility model is necessary to provide a kind of double screw extruder of inner wall belt ridge, the material of extrusion device
Ridge is provided with cylinder, is engaged with specific screw rod, helps so that the extrusion shearing power of screw rod evenly so that product quality is more
It is high.
A kind of double screw extruder of inner wall belt ridge, including support, double screw extruder, drive device, heater
And cooling device；
The double screw extruder includes barrel and two screw rods being arranged in the barrel；
Two screw rods are arranged side by side, and the inwall of the barrel is in twin nuclei, two centers of the twin nuclei
The rotation overlapping of axles of axle respectively with two screw rods, the inwall of the twin nuclei is provided with ridge, and the ridge is strip, edge
The extension of screw rod direction；
The two ends diameter of the screw rod is more than middle diameter；Height close extrusion of the ridge apart from the material tube inner wall
The part at bar center is higher than close to the part at barrel two ends.
Wherein, the surface of the ridge is smooth.
Wherein, the ridge and the curved face in barrel inner surface junction.
Wherein, the uniform amount of the ridge is symmetrically distributed on the inwall of the barrel.
Wherein, the ridge is identical with the pitch of two screw rods apart from the highest distance of the barrel inner surface.
Compared with prior art, the double screw extruder of inner wall belt ridge described in the utility model, the inwall of barrel is set to double
Ring structure and twin-screw are adapted, and inner wall surface sets ridge, help so that the extrusion shearing power of screw rod evenly, polymer
Evenly, product quality is higher for extent of polymerization.
