Abstract
The invention provides a processing method of polypropylene pipes. According to the method, copolymerized polypropylene, heavy calcium carbonate, glass beads and antioxidants are evenly mixed and stirred; then a mixture is added to a twin-screw extruder to extrude the pipes; and finally, all that is needed is to cool and shape the pipes. The processing method has the advantages that the processing is convenient and the operation is convenient and simple.
Description
Technical field
The present invention relates to a kind of tubing, particularly a kind of polypropylene pipe and preparation method thereof belongs to the pipe technology field.
Background technology
Sustainable development is current global common target, reduces the consumption of the energy, and the protection environment avoids hindering social normal activity more and more to come into one's own.In the cost of plastic conduit engineering and energy consumption, lay link and usually occupy critical role.The outer plastics tubing major part of building is laid with burying and suspension bracket is laid.Traditional suspension bracket is laid, and adopts machinery or manual work that suspension and support is installed at the scene according to designed lines, in suspension and support, installs pipeline then and accomplish to connect and test.
The suspension bracket laying technology has proposed new requirement to tubing and material thereof.Suspension bracket is laid and is different from the tradition laying; Its distinct issues are problem on deformation of tubing and since suspension bracket lay in pipeline by suspension and support it is supported, the pipeline spot film is stressed; Because the precision problem that suspension and support is installed; Make the pipeline discontinuity easily, thereby produce distortion, pipeline is sustained damage and possibly bear concentrated some load.
Summary of the invention
Technical problem to be solved by this invention provides a kind of working method of polypropylene pipe, and this method is easy to operate, and the tubing good hardness of this method processing, and rigidity is strong, is not easy to produce distortion.
In order to solve the problems of the technologies described above, the working method of a kind of polypropylene pipe of the present invention wherein, comprises the steps:
A, with 100 parts of copolymerization grade polypropylenes, water-ground limestone 10-15 part, glass microballon 6-8 part, oxidation inhibitor 0.2-0.4 part mixing and stirring, rotating speed is that 800-900 changes, churning time is 5-6 minute;
B, said mixture is added twin screw extruder, extruding pipe material, the processing condition of extrusion: the extruder barrel temperature is set between 175 ℃-210 ℃, and die temperature is set at 190 ℃-200 ℃;
C, with tubing cooling, typing, get final product.
The working method of above-mentioned polypropylene pipe, wherein, the granularity of said water-ground limestone is 680 orders-800 orders.
The working method of above-mentioned polypropylene pipe, wherein, granularity 200 orders of said glass microballon.
Tubing with this PP Pipe Compound is produced is compared with plain polypropylene tubing; Under the constant situation of other performances, its heat-drawn wire can improve 20-30 ℃, and the rigidity of tubing improves greatly; Its hardness can improve more than 1.5 times; Linear expansivity reduces 30-40%, owing to the raising of heat-drawn wire, has enlarged the range of application of polypropylene pipe; Because the raising of hardness; In the built on stilts quantity that can reduce suspension and support when laying, because the reduction of the coefficient of expansion, the influence of in use being expanded with heat and contract with cold reduces simultaneously; Can reduce the consumption of loop expansion pipe; And can alleviate the basic weight of product after glass microballon is filled greatly, substitute and save more production and use resin, reduce product cost; In addition, of the present invention easy to process, convenient and simple for operation.
