Description
Technical field
The utility model relates to the production line of a kind of bilayer and 3-layer composite material section bar.
Background technology
Can adopt high-intensity fiber reinforced composite section bars to replace in a lot of places of timber or shape of using, to reach to mould for wood or to mould the purpose of Dai Gang.Such as the umbrella stand of parasol, block the household articles of bar handrail and similar clothes-horse and so on etc.Resembling the constant profile shapes of tubing, bar or cross sectional shape that above-mentioned this class uses, to adopt the continuous fiber reinforced composite materials section bar of pultrude process and the production of melt impregnation expressing technique be to be suitable for the most.But, cause being difficult to apply because the hoop resistance to compression of continuous fiber reinforced composite materials section bar is low and surface fiber exposes problems such as pollution always.And directly adopt pure plastic material section bar to come for wood or Dai Gang, then its mechanical strength is not enough, particularly the amount of deflection of goods in other words rigidity do not reach requirement far away.
At the problems referred to above,, then can address this problem satisfactorily if it is compound that fibre-reinforced composite material section bar and plastic material are carried out secondary.Method is to coat one deck plastic material again in fibre-reinforced composite material section bar outside.The hoop compression strength that such two-layer compound section bar is reinforced the inner layer composite material section bar by outer plastic material, the pollution problem that solves the fiber emersion simultaneously is to kill two birds with one stone.
The double-layer composite material section bar commonly used or the production technology of multilayer materials pipe be the method for fractional steps often.Just produce the internal layer section bar earlier, transferred to follow-up unit production intermediate layer or skin again.The plastic cement tubing or the metal tube that twine fiber-reinforced layer such as outsourcing all are to produce like this.Double-deck section bar described in the utility model and three layers of pipe also can adopt the method for fractional steps to produce.Just produce fibre-reinforced internal layer section bar earlier, transfer to again and extrude unit to carry out secondary compound, coat the outsourcing plastic layer.This method of fractional steps production is feasible for the soft section bar that can batch, and just very big problem is arranged if be used on the rigid section.This is because expressing technique is a quantity-produced.If the rigid section of preceding road explained hereafter is cut into one section one section, and then at extruder one section hand fed the last period, the then too low and poor quality's control of efficient.
If the production of connecting of the production unit of front and back procedure, then whole process of production can realize continuous and automatic.
The production method of continuous fiber reinforced composite materials section bar commonly used has pultrude process method, fusion colloid impregnation of fibers expressing technique method, preconsolidation colloid fiber bundle or fibrofelt rolling forming process method etc.On the production unit basis of above-mentioned process, increase by one section re-compounded unit of extruding again, just can produce high strength and the double-layer composite material section bar of any surface finish.Exactly the continuous fiber reinforced composite materials section bar is produced unit and extruded unit and be together in series.Method is that the once-combined material section bar of the rigidity of producing on the front end unit directly is drawn in the mouth mould of extruder, and extruder is extruded the melt plastic cement body and is coated on above-mentioned composite material section bar surface, and cooling, typing, cutting or rolling promptly get goods.
By same mentality of designing, increase by a cover extruder again foremost, composite pipe that then can the production three-decker.Specifically be, produce inner tube by extruder earlier, inner tube is drawn to the stage casing unit, continuous fiber or fibrofelt at its resin-coated dipping in outside are drawn to extruding dies again after the special process solidifying and setting, extrude the coating outer tube, cooling, typing, cutting or rolling obtain goods.
The utility model content
The technical problems to be solved in the utility model is to provide the production line of a kind of double-layer composite material section bar and a kind of 3-layer composite material tubing.Described double-layer composite material section bar, its internal layer are fibre reinforced composites, and skin is the plastic cement clad, and described section bar is tubing, bar or profile shapes.Described 3-layer composite material tubing, its internal layer are the plastic cement pipe, and the intermediate layer is a fiber-reinforced layer, and skin is the plastic cement clad.
The utility model calls simple continuous fiber reinforced composite materials section bar production technology once-combined, and it is compound that the follow-up plastic cement cladding process that carries out on above-mentioned composite material section bar basis is called secondary.
For solving the agricultural technology problem of above-mentioned double-layer composite material section bar, the technical solution of the utility model is with the production unit of continuous fiber reinforced composite materials section bar and follow-uply is used for the re-compounded unit of extruding and connects.The production method of continuous fiber reinforced composite materials section bar commonly used has pultrude process method, fusion colloid impregnation of fibers expressing technique method, preconsolidation colloid fiber bundle or fibrofelt rolling forming process method etc.The utility model is not limited to the above-mentioned commonly used once-combined production method of mentioning, so long as with the production unit of once-combined section bar with extrude unit and connect, the production line of producing the secondary composite material is exactly a rights protection claimed range of the present utility model.
The concrete technological process of described double-layer composite material section bar production method is: will produce the fiber reinforced composite section bars that unit produces from leading portion and directly be drawn to extruder, send extruding dies to, coat plastic layer on above-mentioned section bar surface by expressing technique.
For solving the agricultural technology problem of above-mentioned 3-layer composite material tubing, the technical solution of the utility model is that the front end at above-mentioned double-layer composite material product production line increases by one again and extrudes unit, realizes that the series connection of three units is produced continuously.It puts in order is leading portion for extruding unit, the production inner tube, and the stage casing is that once-combined section bar is produced unit, produces the median fiber enhancement layer, back segment is for extruding unit, production plastic cement clad.
The concrete technological process of described 3-layer composite material tubing production method is: the inner tube that the leading portion extruder is extruded is drawn to the once-combined unit in stage casing, coat continuously pre-latex bonded fibre or continuously pre-latex bonded fibre felt in its outside, and it is common by typing mouthful mould solidifying and setting, above-mentioned semi-finished product bimetallic tube directly is drawn to back segment extrudes unit, send extruding dies to, coat the outsourcing plastic layer on the aforementioned tubes surface by expressing technique.
Adopt production line of the present utility model and production method can realize continuous automatic production bilayer or multilayer materials section bar, have the high characteristics of efficient.
Good, any surface finish of product strength that the utility model is produced.The hoop compression strength that has solved simple once-combined material section bar fully is low, the shortcoming that products surface quality is not good.
