The specific embodiment
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is carried out detailed elaboration.
FRP is the abbreviation of Fiber Reinforced polymer (fibre reinforced materials).
As depicted in figs. 1 and 2; The utility model provides a kind of FRP muscle composite stainless steel pipe; Comprise stainless steel tube 20, be fastened on the FRP muscle 10 of said stainless steel tube 20 outer surfaces; Said FRP muscle 10 comprises bossing 11 and shape of threads part 12, and said shape of threads part 12 continuous distributed are in said FRP muscle 10.Under the situation that guarantees FRP muscle composite stainless steel pipe each item performance indications, effectively reduce the wall thickness of stainless steel tube 20, reduce material cost and material weight; And adopt FRP muscle 10 to meet environmental protection, conservation-minded society's growth requirement.
Shape of threads part 12 is horizontally set on FRP muscle 10; Because the shape of threads part 12 of FRP muscle 10 can be in horizontal and vertical generation drawing stress; Guaranteeing that FRP muscle 10 has enough longitudinally outside the tensile stress; Simultaneously can greatly strengthen FRP muscle 10 vertical twisting resistances, guarantee the hoop performance of FRP muscle 10, make FRP muscle 10 can satisfy different instructions for uses.
FRP muscle composite stainless steel pipe is that stainless steel tube 20 places this FRP muscle 10 middles through 4 pultrusions are pre-formed as cylindrical FRP muscle 10 at the stainless steel outer surface through buncher with fortifying fibre and resin compound; Utilizing rotation to twine head again is wrapped in the ribbon polypropylene on the FRP muscle 10 of pultrusion; FRP muscle 10 forms groove under polyacrylic pultrusion effect; Groove makes FRP muscle 10 and stainless steel tube 20 tighten together effectively; Hauling machine vertically pulling and rotation twine acting in conjunction that head radially twines formation shape of threads part 12 down, promptly to connect together continuously be exactly shape of threads part 12 to groove.
Said stainless steel tube 20 thickness >=0.2mm, the thickness that can select said stainless steel tube 20 is 0.5mm, preferably the thickness of stainless steel tube 20 is 0.2mm; Thickness >=the 1mm of said FRP muscle 10, the thickness of preferably said FRP muscle 10 are 2～3mm.The utility model adopts the thick stainless steel tube 20 of 0.2mm to support as inwall; Stainless steel tube 20 guarantees its corrosion resistance; Performances such as internal pressure-resistant change consumption, thickness or the material of outsourcing FRP muscle 10 by the product specification requirement; Can effectively guarantee to reduce material cost and material weight under the condition of corrosion resistance and each item mechanical property requirements of tubing, cost advantage and weight advantage are provided for product uses.
Said shape of threads part 12 materials are polypropylene, and the width of said shape of threads part 12 is 5mm, and thickness is 2mm.Shape of threads part 12 is tied fortifying fibre tight and is in the same place with the resin mixture, local FRP muscle 10 diameters that polypropylene flat-filament is reined in are a little bit smaller, and the local diameter of not reining in just as spiral so take a fancy to more greatly.The FRP muscle composite stainless steel pipe that the utility model is produced, FRP muscle 10 can connect through nut for the continuous thread shape makes between the tubing, has solved the limitation of pipe applications well.
The material of said bossing 11 comprises fortifying fibre and resin.The weight percentage of fortifying fibre is 75%, and the weight percentage of resin is 25%.Said fortifying fibre is any one in glass fibre, aramid fiber, polyethylene fibre, basalt fibre, carbon fiber, ramee, flax fiber, the tossa.Said resin is any one in the unsaturated-resin, epoxy resin, vinyl ester resins in the thermosetting resin.
This instance is a fortifying fibre with the glass fibre, is matrix resin with the vinyl ester resins, gets FRP muscle composite stainless steel pipe through the preparation of pultrusion heat cure moulding process.
Wherein, the vinyl ester resins glue is to be mixed by vinyl ester resins, coupling agent, benzoyl peroxide, peroxidized t-butyl perbenzoate, styrene, filler and mill base; Wherein, get parts by weight and be 100 parts vinyl ester resins, at the parts by weight that add other each component be: coupling agent 0.5-3.0 part; Benzoyl peroxide 0.2-1.0 part; Peroxidized t-butyl perbenzoate 0.8-1.8 part, styrene 2-10 part, filler 3-10 part and mill base 0.5-1.5 part.
FRP muscle composite stainless steel pipe mainly prepares moulding process can be divided into following preparation section:
Send the yarn → impregnation → collection of filaments → stainless steel tube to insert → preformed → winding typing → traction → curing molding → cutting
The preparation technology of the utility model FRP muscle composite stainless steel pipe adopts traditional pultrusion heat cure moulding process, and scrap build requires little, can on existing pultrusion Wiring apparatus, produce, and application prospect is extensive.
Specifically describe the forming preparation process of the utility model below in conjunction with accompanying drawing 3:
(1) described glass fibre places on the fiber creel 1, draws the hole share split traction after several of threading board 2 are entried, and under the effect of tractive force, gets into resin storage tank 3 and carries out impregnation, and glue is above-mentioned vinyl ester resins glue;
(2) glass fibre behind the impregnation is extruded resin adhesive liquid more than needed on the fiber through buncher 4 and pre-shaping device 5 successively under the effect of tractive force; Stainless steel tube 20 is presented to the middle of glass fibre simultaneously; Stainless steel tube 20 with the glass fibre behind the impregnation by hauling machine toward front haulage; Under the effect of the extrusion die of pre-shaping device 5, the mixture of glass fibre and resin is in the braiding of stainless steel tube 20 outer surfaces and tentatively be shaped to columniform FRP muscle 10 shapes;
(3) preformed cylindrical FRP muscle 10 is again through mould and winding head 6; Further extrude resin adhesive liquid more than needed; Utilize rotation winding head the ribbon polypropylene to be wrapped on the FRP muscle 10 of pultrusion again, vertically spur under the acting in conjunction of radially twining at hauling machine and be fixed to the FRP muscle 10 that the surface has continuous thread shape part 12 with rotation winding head;
(4) the FRP muscle composite stainless steel pipe of process above-mentioned steps gets into the drying tunnel of the device 7 that is heating and curing under the effect of tractive force, the generation curing reaction that under the temperature that configures, is heated, and finally obtaining configuration of surface is the FRP muscle composite stainless steel pipe of continuous thread shape.
(5) last FRP muscle composite stainless steel pipe draws to cutter sweep 9 through draw-gear 8 and cuts into satisfactory FRP muscle composite stainless steel pipe finished product.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is only limited to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
