Description
Technical field
The invention belongs to bellows preparing technical field, and in particular to a kind of enhanced double-wall corrugated pipe of bellmouth and its preparation
Method.
Background technology
In recent years, the plastic conduit industry of China obtains the development of high speed, and application field constantly expands, it has also become its people's warp
One of important industry in Ji.《National chemical building material industry the Tenth Five-Year Plan (2001-2005) and development planning outline in 2015》、《The Ministry of Construction pushes away
Wide application and limitation prohibit the use of technology》The application field and developing goal of various plastic conduits are it is also proposed Deng associated documents.
Polyethylene（PE）Double-wall corrugated pipe relies on its excellent performance, is even more in municipal drainage, drainage project and is rapidly progressed.
Polyethylene（PE）Double-wall corrugated pipe is a kind of plastic construction wall tube material, and extruded molding mode is processed.Tubing
It is general using socket joint connection, but due to polyethylene raw material qualitative factor, and moulding process feature limitation, often result in double
The intensity of wall bellows female end is poor, and ring stiffness is relatively low, yielding, and carrying out, sealing property when socket joint is connected is bad,
Easily cause leakage even to destroy, cause in many practical engineering applications, polyethylene（PE）The superiority of double-wall corrugated pipe is simultaneously
Really embodied.Therefore, the intensity of bellmouth connecting portion is whole pipe-line system weak link.Current most domestic enterprise
Industry is all avoiding this technical task, is not solved from front substantially.
The content of the invention
For the above-mentioned problems in the prior art, it is an object of the invention to provide one kind in female end outer wall
It is compounded with enhanced double-wall corrugated pipe of bellmouth of PE self-reinforcing bands and preparation method thereof.
A kind of described enhanced double-wall corrugated pipe of bellmouth, including bellows body, it is characterised in that the bellows body two
End termination is respectively female end and socket end, is compounded with PE self-reinforcing bands on the outer wall of female end, and PE self-reinforcings band with
The surface of female end tube wall contact is provided with fin, and fin steps up thickly to be combined between making PE self-reinforcings band and female end tube wall more
Together.
The described enhanced double-wall corrugated pipe of a kind of bellmouth, it is characterised in that PE self-reinforcing bands are at least one layer.
The described enhanced double-wall corrugated pipe of a kind of bellmouth, it is characterised in that fin is triangular structure.
The described enhanced double-wall corrugated pipe of a kind of bellmouth, it is characterised in that fin is 4-6 groups, is uniformly arranged on PE from increasing
On the surface that strong band is contacted with female end tube wall, fin is highly 4-6mm.
The preparation method of the enhanced double-wall corrugated pipe of described bellmouth, it is characterised in that first prepare bellows body, and by ripple
The two ends of line body are set to female end and socket end, then are twined in female end outer layer by ultrasonic continuous welding combination process
Around one or more layers PE self-reinforcing band of welding.
The preparation method of the enhanced double-wall corrugated pipe of described bellmouth, it is characterised in that the forming method of PE self-reinforcing bands is such as
Under：PE self-reinforcing pieces, then cooling shaping are extruded by single screw rod PE sheet extruders, by drawing drawing at a temperature of 60-80 DEG C
Orientation enhancing is stretched, PE self-reinforcing bands are finally cut into.
The preparation method of the enhanced double-wall corrugated pipe of described bellmouth, it is characterised in that the width and bellmouth of PE self-reinforcing bands
The width matching at end, the width of PE self-reinforcing bands is 20-30mm.
The preparation method of the enhanced double-wall corrugated pipe of described bellmouth, it is characterised in that winding welds one or more layers PE certainly
The technique for strengthening band is as follows：By bellows body frame on support, PE self-reinforcings are fitted in into holding for bellows body with ring winding
Mouth end outer surface, makes the tube wall of female end and PE self-reinforcings band be in the middle of the fixture of ultrasonic equipment in the lump, increases certainly with PE
Apply ultrasonic frequency on the strong fixture face with contact, pressure is applied to fixture, slowly clamping makes PE self-reinforcing bands tightly weld
Female end outer surface is compounded in, the step is repeated and is welded one or more layers PE self-reinforcing band in the winding of female end outer layer.
The preparation method of the enhanced double-wall corrugated pipe of described bellmouth, it is characterised in that ultrasonic frequency is 10-20KHZ,
It is 10-15kPa that fixture applies pressure.
By using above-mentioned technology, compared with prior art, beneficial effects of the present invention are as follows：
1）The present invention welds complex technique and winds welding PE self-reinforcing bands in female end outer layer by ultrasonic continuous, due to ultrasound
It is kind of a thermal weld, the mechanical oscillation that its origin of heat causes in ultrasonic wave, when ultrasonic wave is drawn towards connecing for plastic weld that wave soldering connects
When touching surface, the molecule on the surface fast vibration by ultrasonic excitation, molecule cause because of vibration it is continuous it is alternate be pressurized and
Decompression, causes generation friction between weldment surface, and mechanical energy is changed into heat energy, raises interface temperature, made by high frequency oscillation
Plastic molten melt and compoiste adhering, the method only carry out heat fusion, caloric value and required little energy, speed of welding to contact surface
Hurry up, efficiency high, energy consumption is low, material is not decomposed, it is indeformable, easy to operate the features such as, it is cost performance highest, more reasonable；
2）The present invention contacts not tight, PE self-reinforcing bands with female end outer surface and contacts compound tense very for PE self-reinforcings band
The problem that hardly possible is fitted completely, fin is designed in PE self-reinforcings belt surface, and fin is defined into 4-6 groups, and fin is highly 4-
6mm, can be such that PE self-reinforcings band is effectively adjacent to bellmouth outer wall, and ultrasonic energy first passes through fin and passes to bellmouth face and makes contact portion
Soften fusion, PE self-reinforcings band is further combined welding with bellmouth face under the extruding of cylinder, and the technology is avoided that
Bellmouth position distortions, improve bellmouth intensity, and PE self-reinforcing bands are combined on the outer wall of the female end obtained by the technology
Afterwards, humidification has been reached；Increase the compound number of plies of PE self-reinforcings band winding, can further increase the intensity of female end.This
The performances such as female end ring stiffness, the connection sealing of invention are obviously improved.By contrast test, after female end enhancing is compound,
The ring stiffness of female end is increased by 500 the above, and connection sealing is substantially improved.
