Description
Technical field
The present invention relates to bury the production material and the complete processing thereof of the plastic conduit that the ground draining uses.
Background technology
At present, producing and bury the plastic conduit that the ground draining is used, generally all is to produce with polyvinyl resin and polyvinyl chloride (U-PVC) resin.And double-wall corrugated pipe is that the same big tubing of bore is that materials are economized most in the underground pipe material, structure, the most rational a kind of structural tube of intensity.
With polyethylene (PE) is the double-wall corrugated pipe of main material production: advantage is that good toughness, shock resistance are good, winter hardiness is good.But its disadvantage is: 1, elasticity modulus of materials is low, and product strength is low, and the materials amount is many.2, resistance to elevated temperatures is poor, and especially south summer, temperature under the sun was higher than the obvious step-down of tubing rigidity more than 30 ℃, and interface is yielding, difficult insertion, constructional difficulties, easy to leak.
With polyvinyl chloride (U-PVC) is the double-wall corrugated pipe of main material production: its advantage is that intensity is big, elasticity modulus of materials height, difficult combustion.But its shortcoming is: starting material add the poor heat stability in man-hour, and especially large diameter pipeline is difficult to moulding, and chance high temperature easily decomposes, flowability is poor, and general production can only be at bore all less than ￠ 600 following tubing, and heavy caliber pipe is difficult to produce.2, winter hardiness is poor, and shock resistance is poor, especially to winter fragility big, be difficult for construction.
Summary of the invention
Goal of the invention of the present invention provides a kind of multipolymer that is used to produce polypropylene double-walled reinforcement bellows.
Another goal of the invention of the present invention provides a kind of preparation method who is used to produce the multipolymer of polypropylene double-walled reinforcement bellows.
In order to solve the problems of the technologies described above, the invention provides following technical proposals:
The multipolymer that is used to produce the reinforcement double-wall corrugated pipe comprises following component and weight part:
Acrylic resin 75-100
Chlorinated polyvinyl chloride 2-15
Lime carbonate 15-80
Talcum powder 10-60
Ployethylene Wax dispersion agent (PE is cured) 0.1-2

Four [β-(3 ', 5 '-di-t-butyl-4 '-hydroxy phenyl) propionic acid] pentaerythritol ester (antioxidant 1010) 0.1-1.5
Further: the paraffin wax that also comprises 0.1～1.5 weight part;
Further: the lead salts stablizer (PbSt) that also comprises 0.2～3 weight part;
Further: also comprise 0.3～3 parts by weight of carbon black;
A kind of preparation method who is used to produce the multipolymer of polypropylene double-walled reinforcement bellows: by following production in series;
(a) raw material is carried out batching weighing by certain weight ratio;
(b) the described batching of step (a) is mixed with mixing at high speed mixer;
(c) mixture of previous step being made suddenly adds the technological temperature of twin screw extruder and setting and extrudes;
Wherein, the mixed temperature of the heat of high speed mixer is 100-125 ℃; Cold mixed temperature is below 60 ℃; High speed mixer is a SRL type high speed cold Hot mixer group,
Twin screw extruder is the SJZ conical double screw extruder, universal equipment be 65 machines-95 machines, wherein each segment process temperature of machine barrel is: 160～190 ℃ of feeding sections; 180～210 ℃ of fluxing zones; 190～230 ℃ of homogenizing zones, extruder screw rotating speed are 15 rev/mins～40 rev/mins; Forcing machine feeding rotating speed is 10 rev/mins～40 rev/mins.
The double-walled reinforcement tube wave line tubing that uses the present invention to produce is compared with other like product, and following advantage is arranged:
(1), the polypropylene double-walled reinforcement pipe corrugated tube of employing the present invention production has significantly raising with respect to the twin wall emitter lateral corrugated tube of prior art production on the use weather resistance, especially when constructing southern summer, be exposed to the sun down at the high temperature and the sun more than 35 ℃, the double-walled reinforcement pipe corrugated tube tubing that adopts the present invention to produce is indeformable; But adopt PE double-wall corrugated pipe bell and spigot with regard to yielding, more difficult insertion, constructional difficulties, easily leak.If when constructing for subzero about 5 ℃, adopt the double-walled reinforcement pipe corrugated tube of the present invention's production in the winter time, winter resistance is better, can damaged and fracture.Adopt PE double-wall corrugated pipe ring stiffness then obviously to descend easy deformation; And the pvc pipe material is difficult for construction and installation generally in subzero 5 ℃ of crackies and fracture.
(2), the polypropylene double-walled reinforcement pipe corrugated tube that adopts the present invention to produce, its mechanical property significantly improves, elasticity modulus of materials is to adopt more than 2 times of PE double-wall corrugated pipe.General PE elasticity modulus of materials (Mpa) is 800～900, and adopt double-walled reinforcement tube wave line tubular elastic modulus that the present invention produces at (Mpa) more than 2500～3000.
(3), the polypropylene resin great advantage is good fluidity, is easy to machine-shaping, especially is fit to produce heavy caliber pipe.The double-walled reinforcement pipe corrugated tube that adopts the present invention to produce, because elasticity modulus of materials significantly improves, at the double-wall corrugated pipe of producing equal bore, ad eundem rigidity, the double-walled reinforcement pipe corrugated tube that employing the present invention produces than PE double-wall corrugated pipe materials amount still less, generally can economize 15～20% material, so its cost performance and the market competitiveness more have superiority.
(4), the tubing cylindrical vertically increases reinforcement design, makes the double-wall corrugated pipe transverse strength higher, the tubing stress performance is more rationally, evenly.
(5), the polypropylene double-walled reinforcement pipe corrugated tube resistance toheat that adopts the present invention to produce is better, its heat-drawn wire can reach about 150 ℃, and adopts tubing heat-drawn wire that PE and PVC produce generally below 85 ℃.So the polypropylene double-walled reinforcement pipe corrugated tube that adopts the present invention to produce is specially adapted to the draining in chemical plant, blow-off line.
Embodiment
The present invention will be further described according to specific embodiment:
Will be according to the weight part confected materials at high mixer high speed batch mixing, it is mixed cold mixed to carry out heat; Again mixed batch mixing is processed by the further copolymerization of SJZ conical double screw extruder; Promptly get the multipolymer that is used to produce polypropylene double-walled reinforcement bellows at last.
