Abstract
The invention discloses a composition and manufacturing technique of reinforced pipe of big diameter reinforced composite polypropylene, which comprises the following parts: 75-100% polyvinyl chloride, 5-15% chlorinated polyethylene, 5-20% polypropylene, 4-6% acrylic ester, 20-40% heavy calcium carbonate, 5-15% ternary ethylen-propylene rubber, 5-6% lead salt stabilizer and 0.5-1.0% stearic acid. The invention can produce new FRPP material through copolymerizing and blending, which overcomes the difficulty of big diameter reinforced pipe and secondary manufacturing.
Description
Technical field
The present invention relates to the production material and the production technique thereof of riffled tube, be specially the production material and the production technique thereof that are used to produce the heavy caliber riffled tube, refer to produce the production material and the production technique thereof of large-calibre reinforced polypropylene (FRPP) riffled tube especially.
Background technology
For a long time, domestic enterprise generally all is to utilize a kind of major ingredient when producing the heavy caliber drainage pipeline, suitably joins other auxiliary materials and produces.But the water shoot performance of Sheng Chaning is not very desirable in this way.
As polychloroethylene pipes, its thermostability, shock resistance are relatively poor, and its thermal fluidity of work in-process is also relatively poor.The tubing of this material is difficult to produce the heavy caliber riffled tube, and the general bore of the tubing of production is all less than DN600mm.
Polyvinyl piping materials for another example, its elasticity modulus of materials coefficient is little, and ultimate compression strength is poor, and suitability for secondary processing is poor, and is high temperature resistant poor, and the prices of raw and semifnished materials are higher.The tubing of this material is yielding in south, and construction inconvenience is easily leaked.
The at present domestic above FRPP riffled tube of heavy caliber (DN800mm) of still can not producing.
Summary of the invention
The purpose of this invention is to provide a kind of composition of producing large-calibre reinforced polypropylene stiffened pipe.
Another object of the present invention provides a kind of production technique of producing the composition of large-calibre reinforced polypropylene stiffened pipe.
In order to solve the problems of the technologies described above, the invention provides following technical proposals:
The material that is used to produce large diameter glass fiber reinforcement polypropylene reinforced pipe comprises following component and weight part:
Polyvinyl chloride 75～100
Chlorinatedpolyethylene 5～15
Polypropylene 5～20
Acrylate 4～6
Water-ground limestone 20～40
Ternary third rubber 5～15
Lead salt stabilizer 5～6
Stearic acid 0.5～1.0.
The order number of water-ground limestone is 2500-3000.
Further, comprise that also the oxidic polyethylene of 0.4～1.0 weight part is cured.
Further, the paraffin wax that also comprises 0.4～1.2 weight part.
Further, also contain 0.5～1.5 parts by weight of carbon black.
Be used to produce the production technique of the composition of large-calibre reinforced polypropylene stiffened pipe: by following production in series:
(a) each component of aforementioned techniques scheme is prepared burden by described weight ratio;
(b) the described batching of step (a) is carried out heat in high mixer and mix cold mixing;
(c) material after step (b) is mixed adds forcing machine and carries out extruding pelletization;
(d) the rapid middle material grain that generates of previous step is carried out copolymerization processing by 95 twin screw extruders.
Technique effect of the present invention is: use the present composition to produce the heavy caliber riffled tube, efficiently solve and produce the shortcoming that the heavy caliber riffled tube is difficult to moulding and secondary processing difficulty, and the heavy caliber riffled tube that uses the present composition to produce, resistance to elevated temperatures is strong, is specially adapted to chemical pipeline blowdown (acid-fast alkali-proof is corrosion-resistant); The Young's modulus coefficient is much higher than the pipe that the HDPE material produce is come out; And tension ultimate compression strength height.
Embodiment
The present invention will be further described according to specific embodiment:
At first raw material is prepared burden the weight part of each raw material such as following table by certain weight ratio; Then 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 added forcing machine and carry out extruding pelletization; Then the rapid middle material grain that generates of previous step is processed by the further copolymerization of 95 twin screw extruders; Promptly get the composition that is used to produce large-calibre reinforced polypropylene stiffened pipe at last.
