Abstract
The invention discloses a low temperature resistant high-tenacity PVC (Poly Vinyl Chloride) flexible pipe which is composed of the following components in parts by weight: 60-80 parts of polyvinyl chloride resin, 2-5 parts of polytrimethylene terephthalate, 10-20 parts of calcium carbonate, 2-5 parts of silicon carbide whisker, 5-10 parts of butadiene styrene rubber, 1-3 parts of antistatic agent and 1-2 parts of paraffin. The silicon carbide whisker is used for the high-tenacity polyvinyl chloride pipe so that the internal structure of the pipe can be effectively strengthened and both the mechanical strength and tenacity between pipes are improved. In addition, the aging resistance of the pipe is improved; a lubricant is applied to the production process so that the material is evener, the lubrication smoothness of extrusion is improved, and also the lubricant functions in enhancing the internal structure; the prepared polyvinyl chloride pipe has the characteristics of high tenacity and high mechanical strength.
Description
Technical field
The present invention relates to a kind of low temperature resistant, high tenacity PVC flexible pipe.
Background technology
Polyvinyl chloride pipe, also claiming PVC pipe, is the tubing that the thermal plasticity high polymer that formed by polymerization of vinyl choride monomer is made, and take polyvinyl chloride (PVC) RESINS as main raw material, add appropriate antiaging agent, properties-correcting agent etc., the material formed through techniques such as mixing, calendering, vacuum formings.PVC pipe resistance to corrosion is strong, it is bonding to be easy to, PVC has very strong resistibility to oxygenant, reductive agent and strong acid.Yet it can be corroded as the vitriol oil, concentrated nitric acid by dense oxidizing acid and the also inapplicable occasion contacted with aromatic hydrocarbon, chlorinated hydrocarbon.But, the PVC pipe, particularly UPVC pipe resistance toheat is poor, and descends in environment tensile strength more than 60 ℃, and under low temperature environment, Vybak water shoot resistance to impact shock reduces.In the transportation, installation and use process, brittle rupture easily occurs; In addition, the performance that the PVC pipe withstands shocks is also poor.
Summary of the invention
The deficiency existed for prior art, technical problem to be solved by this invention is that a kind of low temperature resistant, high tenacity PVC flexible pipe that has good resistance to low temperature, snappiness and antistatic property and can meet low-temperature transport is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of low temperature resistant, high tenacity PVC flexible pipe is grouped into by the one-tenth of following weight part:
Polyvinyl chloride (PVC) RESINS 60～80;
Poly(Trimethylene Terephthalate) 2～5;
Calcium carbonate 10～20;
Silicon carbide whisker 2～5;
Styrene-butadiene rubber(SBR) 5～10;
Static inhibitor 1～3;
Paraffin 1～2.
The present invention is low temperature resistant, the advantage of high tenacity PVC flexible pipe is: high tenacity polychloroethylene pipes of the present invention has been used silicon carbide whisker, can effectively strengthen the structure of tubing inside, and mechanical strength, toughness between tubing all are improved.In addition, improve the resistance to deterioration of tubing; Lubricant can be in process of production, make material more evenly, improved the lubricated planarization of extruding, also played the effect that strengthens internal structure.The polychloroethylene pipes made has the characteristics of high tenacity, high mechanical strength.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
A kind of low temperature resistant, high tenacity PVC flexible pipe is grouped into by the one-tenth of following weight part:
Polyvinyl chloride (PVC) RESINS 60～80;
Poly(Trimethylene Terephthalate) 2～5;
Calcium carbonate 10～20;
Silicon carbide whisker 2～5;
Styrene-butadiene rubber(SBR) 5～10;
Static inhibitor 1～3;
Paraffin 1～2.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
