Description
Technical field
The invention belongs to bellows fields, and in particular to a kind of PP double-wall corrugated pipe and preparation method thereof.
Background technique
Plastic film capicitor uses special " annular groove " formula special-shaped section form in structure design, and this tubing design is new
It is clever, structurally reasonable, " board-like " traditional structure of common tubing is breached, making tubing both has enough resistance to compressions and shock resistance strong
Degree, and there is good flexibility.Different according to the structure of plastic film capicitor, bellows can be divided into single-wall corrugated pipe and double-walled again
Bellows.Single wall plastic film capicitor refers to that the inside and outside wall of plastic tube all has the tubing of ripple, has high rigidity, can be any
Bending, endless package.Double-wall corrugated pipe then refer to inner wall smooth and outer wall have ripple (corrugated shape can for right angle, it is trapezoidal,
Sinusoidal etc.) plastic tube, it is by clinkering extrusion forming of the ripple outer wall squeezed out simultaneously and one layer of smooth inner wall.It is removed
Other than the features such as all corrosion-resistant good of common plastics, insulating properties is high, inner wall smooth, flow resistance is small, because using
Special hollow ring rigidity and good strength and toughness.Highway, side slope, Gao Er can be widely applied in double-wall corrugated pipe
It is drained in the case of the heavy loads such as husband court, is permeable；Municipal blowdown；The occasions such as communication, service cable casing.But market is to double-walled
The performance requirement of bellows is higher and higher, and double-wall corrugated pipe currently on the market is difficult to reach requirement.
Summary of the invention
The purpose of the present invention is to provide a kind of PP double-wall corrugated pipe and preparation method thereof, the double-wall corrugated pipe tools of production
There are splendid wearability, corrosion resistance, shock resistance, and intensity, extreme hardness.
To achieve the above object, the invention provides the following technical scheme:
A kind of PP double-wall corrugated pipe, the raw material including following parts by weight: 90-110 parts of PPR particle, 001 polyethylene powder
23-27 parts, 4-6 parts of 7042 polyethylene powder, 45-55 parts of powdered whiting, 2-4 parts of stearic acid, 7-9 parts of color masterbatch.
Preferably, the PP double-wall corrugated pipe, the raw material including following parts by weight: 100 parts of PPR particle, 001 polyethylene powder
Expect 25 parts, 5 parts of 7042 polyethylene powder, 50 parts of powdered whiting, 3 parts of stearic acid, 8 parts of color masterbatch.
Preferably, the inner and outer wall of the double-wall corrugated pipe be all made of the above parts by weight raw material it is made.
Preferably, the double-wall corrugated inside pipe wall raw material further includes 2-4 parts of carbon fiber, 3-5 parts of mica.
Preferably, the double-wall corrugated pipe outer wall raw material further includes 2-4 parts of molybdenum disulfide.
Preferably, the preparation method of a kind of PP double-wall corrugated pipe, comprising the following steps: weigh each original by weight
Then material is squeezed out respectively by the raw material mixed melting of double-wall corrugated pipe inner and outer wall by extruder, after compression molding again
Cooling and shaping is finally cut, and finished product is made.
Compared with prior art, the beneficial effects of the present invention are:
1) present invention uses PPR particle, 001 polyethylene powder, 7042 polyethylene powders, utilizes different types of polyethylene
The intensity and hardness of double-wall corrugated pipe can be enhanced in material.
2) it is added to carbon fiber and mica in the inner wall raw material of double-wall corrugated pipe, the shock resistance of double-wall corrugated pipe can be improved
And electrical insulation capability.
3) it is added to molybdenum disulfide in the outer wall raw material of double-wall corrugated pipe, the wearability, resistance to of double-wall corrugated pipe can be improved
Corrosivity.
4) present invention adds carbon fiber and mica in inner wall raw material, molybdenum disulfide is added in outer wall raw material, due to double
Wall bellows drains in the case of the heavy loads such as highway, side slope, golf course are widely applied, is permeable；Municipal blowdown；It is logical
The occasions such as letter, service cable casing, so double-wall corrugated pipe needs good wearability, corrosion resistance, by double-wall corrugated pipe
Inner and outer wall raw material adds mention high performance substance respectively, breaches the completely the same situation of traditional inner wall outer wall raw material, can
Preferably to improve the overall performance of double-wall corrugated pipe, cost is reduced, and does not influence its service life.
