Description
Technical field
This utility model relates to a kind of Country Tubular Goods, particularly relates to a kind of electric power polypropylene bilayer single-wall corrugated pipe
Material.
Background technology
The tubing in power cable sheath field is generally HDPE pipe and glass reinforced plastic pipe at present, and wherein HDPE pipe exists following
Shortcoming: 1, elasticity modulus of materials is low, about 800Mpa, thereby result in pipe ring stiffness on the low side；2, poor thermal conductivity, because of material thermal conductivity
Less than 0.32, and tube wall thickness is thicker, and generally more than 8mm causes radiating effect bad, in the most easily causing cable to run
Break down.
Plain polypropylene single-wall corrugated pipe is compared and be there is following shortcoming: 1, weatherability is poor, and tubing is monolayer single wall knot
Structure, plain polypropylene material weatherability is poor in addition, deposits in outdoor and i.e. causes obvious hydraulic performance decline in about 1 month；2, pipe
Material toughness is poor, and tubing is single layer structure, when by external impact, is highly prone to destroy.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of ring stiffness high, good impact resistance, and heat conductivity is good,
The electric power polypropylene bilayer single-wall corrugated pipe material that weatherability is excellent.
This utility model is achieved in that electric power polypropylene bilayer single-wall corrugated pipe material, including outer layer and internal layer, logical
Cross composite die melting together；The most undulatory double-deck single wall ripple struction of described tubing, ripple is by crest and trough
Staggered, corrugated is circular arc " u "-shaped structure and circular arc inverted " u "-shaped structure connects and composes, and the bottom of circular arc " u "-shaped structure is
Crest, the top of circular arc inverted " u "-shaped structure is trough.
Described outer layer thickness is 1～5mm, uses good-toughness and the toughness reinforcing weather resistant modified polypropene material of good weatherability
Material.
Described internal layer thickness is 1～8mm, uses good strength and the good enhancing heat-conducting type modified polypropene material of heat conductivity
Material.
This utility model electric power polypropylene bilayer single-wall corrugated pipe material has the following advantages: described outer layer uses good-toughness
And the enhancing heat conduction that the toughness reinforcing weather resistant modified polypropylene material of good weatherability, described internal layer employing good strength and heat conductivity are good
Type modified polypropylene material, the most special " u "-shaped and the design of inverted " u "-shaped structure, so that tubing has possessed following performance: 1,
Excellent ring stiffness and heat conductivity: because internal layer uses good strength and the good enhancing heat-conducting type modified polypropylene material of heat conductivity,
The most special " u "-shaped and the design of inverted " u "-shaped structure, make tubing have an excellent ring stiffness, typically up to 50KN/m2 with
On, heat conductivity is greatly improved simultaneously, and heat conductivity is up to more than 0.38, and relatively plain polypropylene material improves more than 15%；2, excellent
Toughness and weatherability: because tubing designs for double-decker, outer layer uses the toughness reinforcing weather-proof of good-toughness and good weatherability in addition
Type modified polypropylene material, makes the destructiveness of the anti-external impact of tubing be greatly improved, simultaneously as outer layer is through weather-proof modification,
Add appropriate ultraviolet-resistant absorbent and light stability, improve the overall weather resistance of tubing, effectively protect tubing
At outdoor Long-Term Properties.

Stricture of vagina is by crest (1) and trough (2) staggered, and corrugated is circular arc " u "-shaped structure and circular arc inverted " u "-shaped structure connects and composes,
The bottom of circular arc " u "-shaped structure is crest (1), and the top of circular arc inverted " u "-shaped structure is trough (2).
Described outer layer (3) thickness is 1～5mm, uses good-toughness and the toughness reinforcing weather resistant modified polypropene of good weatherability
Material.
Described internal layer (4) thickness is 1～8mm, uses good strength and the good enhancing heat-conducting type modified polypropene of heat conductivity
Material.
This utility model electric power production method of polypropylene bilayer single-wall corrugated pipe material, the steps include:
Step 1, use A extruder extrusion outer layer (3)；
Step 2, use B extruding layer extrusion internal layer (4)；
Step 3, by composite die, ectonexine (3) is combined with each other, forms double-deck single wall pipe；
Step 4, with mould pipe cooled down under the effect of vacuum and air pressure inside molding；
Step 5, by traction machine traction pulling out tubing continuous-stable；
Step 6, by cutting machine by tubing fixed length cutting.
