Description
Technical field:
The present invention relates to a kind of plastic pipe, especially a kind of PET reinforced composite pipe material and preparation method thereof.
Background technique:
China Plastics Industry has formed industrial system covering extensive fields by long-term development, becomes and steel, cement, wood
The basic material industry that material is run neck and neck.As the plastic industry of one of light industry pillar industry, growth rate one in recent years
It directly is maintained at 10% or more, from the point of view of the production of synthetic resin, plastics machinery and plastic products, it is strong to all show China Plastics Industry
The growth momentum of strength.Existing tubing is generally simple plastic tube, and intensity is low, load performance is poor, in actual service conditions
The lower coefficient of expansion is big, pipeline easily softens and deforms, and the low mass pressure standard for having seriously affected tubing of transverse tensile strength,
It is not easy to be widely applied.In order to increase the intensity of plastic tube, has increase winding wire or spiral in plastic tube in the prior art
The multiple tube that winding steel is produced.But the surface of the winding wire of multiple tube or spiral winding steel belt framework is polarity table
Face, and the interface of the stronger polymer of anti-corrosion ability such as polyethylene is apolar surfaces, the two is difficult to become real composite wood
Material, while increasing pipeline and joining the larger range of application that hot difficulty also affects the pipeline.For existing in the prior art
Problem, the present invention provide a kind of PET reinforced composite pipe material and preparation method thereof, enhance the transverse tensile strength of tubing, improve
Load performance, extends the service life of tubing, has fully demonstrated the superiority of composite pipe.
Summary of the invention:
A kind of PET reinforced composite pipe material and its preparation side are provided it is an object of the invention to overcome the deficiency of background technique
Method.
PET reinforced composite pipe material, the composite pipe are respectively inner tube, PET composite layer and outer tube, institute from the inside to the outside
It is identical with the material of outer tube to state inner tube, is PE, PP or PVC material, by the way that PET strip is wound or woven in the inner tube
Or the technique of the outer tube is coated after PET item again and is prepared.
The preparation method of the PET reinforced composite pipe material, comprising the following steps: (1) with an extruder produce inner tube,
The wall thickness of inner tube is 3/5ths of composite pipe finished product wall thickness；(2) after vacuum sizing is cooling, with wrapping machine PET
Band or item are wound on inner tube outer tube wall；(3) the internal layer pipe surface for having wound PET strip or item is covered with an extruder again
One layer of outer tube；(4) mold sizing；(5) sink is cooling；(6) coder stamp；(7) according to using length to cut；All stream
Cheng Yici online production, dragger traction molding, composite pipe are automatically placed on piling bin.
The preparation method of the PET reinforced composite pipe material, comprising the following steps: (1) with an extruder produce inner tube,
The wall thickness of inner tube is 3/5ths of composite pipe finished product wall thickness, and extruder temperature is divided into five sections when producing inner tube:
One 155 DEG C of area, 170 DEG C of 2nd area, 180 DEG C of 3rd area, 190 DEG C of 4th area, 195 DEG C of 5th area, 195 DEG C of head；Head gap is controlled, is increased
Add longitudinal stretching；(3) after drawing machine travel, PET strip or item are woven on inner tube outer tube wall with braider；(4) through next
Platform extruder is coated in the outer tube raw material melted by head the internal layer pipe surface for having woven PET strip or item；All stream
Cheng Yici online production, dragger traction molding, composite pipe are automatically placed on piling bin.
Ectonexine pipe uses hot-melt adhesive paste technique using the composite pipe of PE, and be pressurized in 3 seconds connection after hot melt, the PET
Band or PET item are coated among the tubing section, are heated tubing section described in the contact heater plate of heater, are heated to 250
DEG C when heating plate is removed rapidly, the compression heat sealing in 3 seconds；Ectonexine pipe is used using the composite pipe of PP and gulps down the side connect
Method and hot-melt adhesive paste；Ectonexine pipe is connected using the composite pipe of PVC using the method for support mouth.
PET strip is commonly called as plastic-steel belt, is able to achieve in terms of tensile property to mould Dai Gang.The longitudinal stretching force of PET strip or PET item
In terms of thick 1mm, width 10mm, pulling force every square centimeter is 336kg, and in terms of thick 1.2mm, width 32mm, pulling force every square centimeter is
1000kg.Composite pipe of the present invention is twined on the tubing circumference tube wall that PE, PP or PVC material are produced with PET strip or PET item
Around or braiding after coat one layer of PE, PP or PVC material again, be firmly bonded to PET strip or PET item in inner tube, according to pipe
Material actual use pressure requirements more can wind or weave several layers of PET strips or PET item.
PET reinforced composite pipe material of the present invention can increase by 10 times or more of bearing capacity than the tubing of same specification wall thickness.
Once strong was compared with common tubing simultaneously than endurance inside and outside a kind of tubing of material merely for composite pipe, and two kinds of the present invention
The composite pipe of technique production can save the raw material of nearly one third, if the whole nation all using composite pipe of the invention and
Production technology can save 1,000,000 tons of raw material or more every year.Open source information shows that the whole nation uses plastic pipe 1200 every year
Ten thousand tons, it can be seen that, the present invention has very big social benefit and economic benefit, can reduce carbon emission, and it is dirty to reduce air
Dye can also make PET beverage bottle waste material realize recycling and reusing.Composite pipe resistance to pressure produced by the invention is good, at low cost, raw
It produces high-efficient, has a vast market application prospect.
