Abstract
A reinforced polypropylene corrugated pipe for buried high-voltage power cables belongs to the technical field of pipelines and comprises a pipe wall and corrugated protrusions arranged outside the pipe wall. The reinforced polypropylene corrugated pipe is characterized in that modified polypropylene materials are adopted for the pipe wall and the corrugated protrusions which are both formed through the corrugation co-extrusion process, and reinforced ribs are arranged in the length direction of a corrugated sleeve to enhance the strength of the pipe wall. The reinforced polypropylene corrugated pipe has the advantages of being simple in manufacture process, convenient to assemble, demount and overhaul, good in waterproof sealing performance and flexibility and low in production cost. In addition, materials cannot be formed easily.
Description
Technical field
The present invention relates to the pipe technology field, especially relate to a kind of buried high voltage power cable RPP bellows.
Background technology
The construction development in city proposes higher requirement to the provided underground cable.Complexity and particularity due to urban environment; the buried cable laying form of construction work of non-excavation is to urban environment; the people's lives impact is than other modes little (for example grooving pipe laying form of construction work); the better form of construction work of present city cable laying, the performance requirement that the protection pipe box requires and this form of construction work adapts.
At present published is a kind of M-PP pipe (power cable protecting pipe) for what coordinate this form of construction work use, and the MPP pipe claims again the MPP power cable protecting pipe, and the employing modified polypropene is main raw material(s).
Yet, the MPP pipe is hollow and the inside and outside smooth insulation pipe of tube wall, this pipe is the walled tube of rigid pipe, but, due to the tortuous roundabout occasion in the path of laying power cable, the MPP pipe of the planomural of the rigid insulation that inside and outside tube wall is smooth can't be complied with the complicated and changeable of laying-out as natural torsion, limits its environment for use; The MPP pipe is deposited in the job site and takies very large construction site, is unfavorable for constructing under narrow environment, and therefore a kind of buried high voltage power cable is necessary with the appearance of RPP bellows.
Summary of the invention
The present invention is to provide a kind of good toughness that has for solving the problems of the technologies described above, the buried high voltage power cable RPP bellows that production cost is low.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of buried high voltage power cable RPP bellows, the ripple projection that comprises tube wall and tube wall outside, it is characterized in that, described tube wall and described ripple projection adopt modified polypropylene material, form by the ripple coextrusion process, along described corrugated bushing length direction, reinforcement is arranged, to strengthen the intensity of tube wall.
The weight ratio formula of described modified polypropylene material composition is M-PP resin 75～84%, M-PP dedicated modified materials 10～12%, PP color masterbatch 3%, other processing aids 1～10%.
The weight ratio formula of preferred described modified polypropylene material composition is M-PP resin 80～84%, M-PP dedicated modified materials 10～12%, PP color masterbatch 3%, other processing aids 1～7%.
The beneficial effect that the present invention has is, manufacturing process is simple, material is difficult for being shaped, the assembly and disassembly maintenance is convenient, and waterproof sealing is good, pliability good, production cost is low.
Description of drawings
Fig. 1 is the present invention: a kind of buried high voltage power cable RPP bellows structure schematic diagram.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
With reference to shown in Figure 1, a kind of buried high voltage power cable RPP bellows, the ripple projection 2 that comprises tube wall 1 and tube wall 1 outside, tube wall 1 and ripple projection 2 adopt modified polypropylene material, form by the ripple coextrusion process, along the bellows length direction, reinforcement 3 is arranged, to strengthen the intensity of tube wall.
The weight ratio formula of modified polypropylene material composition is M-PP resin 75～84%, M-PP dedicated modified materials 10～12%, PP color masterbatch 3%, other processing aids 1～10%.
The weight ratio formula of preferred modified polypropylene material composition is M-PP resin 80～84%, M-PP dedicated modified materials 10～12%, PP color masterbatch 3%, other processing aids 1～7%.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
