Embodiment
To better understand the objects, features and advantages of the present invention, with reference to specific embodiment pair
The present invention is described further.It should be noted that in the case where there is no conflict, the spy in embodiments herein and embodiment
Sign can be mutually combined.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention may be used also
With using implementing different from other modes described here, therefore, the present invention is not limited to the specific of specification is described below
The limitation of embodiment.
Embodiment 1, the present embodiment provides the specific production technology of fiber prestress thermoplastic composite tube.Specific steps are such as
Under：Immersed after fiber is tensioned first and by the way that in the thermoplastic resin mould under molten condition, leaching moulds postcooling to room temperature system
Composite band into strips, compound tep reel can be equipped use.The thickness and width of composite band is managed when can be according to actual processing
What the diameter and thickness of material was adjusted.When processing tubing, the composite band root of needs is determined according to the thickness of tubing and diameter
Number, is drawn through combustion heater by more composite bands are parallel, the form of combustion heater is multi-lamellar up and down, between every layer
The gap that reserved composite band passes through, the form of every layer of combustion heater is the spray gun of two rows linear distribution, and spray gun front end is set
There is nozzle, when composite band at the uniform velocity passes through spray gun, its surface is heated and becomes have sticking molten condition；Then by melt surface
More composite bands continue traction to paper tube machine, in the pipe mold surface wrap of paper tube machine, form tubing；By tubing and mould
Depart from, and intercepted according to required length.
Combustion heater one end is responsible for equipped with combustion gas, and combustion gas supervisor enters combustion heater main body after shunting, fires
Hot-air heater body interior includes the more hollow gas pipes being arranged in parallel, and the both sides of hollow gas pipe are arranged with gas outlet
The linear spray gun group of composition, each gas outlet are connected with the nozzle of a spray gun, and combustion heater can also include temperature
Control structure, can also manually-operated gate control to control the temperature and flame size of the flame of nozzle ejection.Linear distribution
The flame that spray gun group sprays faces composite band, and the gap that composite band can pass through, the spray gun are reserved between adjacent spray gun group
Group width is of same size with composite band.It should be noted that the model that paper tube is similar, and paper tape coats is rolled into reel machine with paper tape
It is medial surface to enclose, and topmost the downside of the upper side of one layer of paper tape and bottom one layer of paper tape is not gluing；Likewise,
The not exposed surface of composite band needs to be heated to molten condition in the present invention, and the upper side of one layer of composite band and most topmost
The downside of one layer of composite band below（Namely close to mould producing the inner surface of multiple tube and answering close to air
Close the composite band of the outer surface of pipe）Molten condition is heated to also without with spray gun.To produce diameter 200mm, thickness 5-20mm
Multiple tube exemplified by, and by taking glass fiber tape is immersed in the PE resins of melting as an example, use 5 layers of PE fibre resin bands, pass through
The extruding postcooling of extruder, is prepared width 150-300mm, the PE fibre resin bands of thickness 0.8-1.8mm, if control is permanent
Incubator（Combustion heater continuous heating, forms the environment of a constant temperature）Temperature between 180 DEG C to 260 DEG C, PE fiber trees
Fat band is 50-160m/min into tape speed, then PE fibre resins band can reach the state of melt surface；By melt surface shape
The PE fibre resin bands of state continue traction to reel machine, and required PE multiple tubes can be produced under the afterturn of reel machine.
The speed of PE multiple tube outlet pipes can freely control between 0.1m-30m.The intensity requirement of pipe is different, the fibre that can be selected
It is different to tie up species and thickness and radical.The present invention is improved on the Process ba- sis of traditional paper tube machine production paper tube,
Thermosetting resin after fibre strengthening is processed into composite band and replaces paper tape；And make its melt surface with spray gun heating composite band
Replace needing the process in paper tape surface adhesive coating during traditional paper tube production with viscosity, be designed to by above-mentioned
Thermoplastic composite tube is produced, fiber is not readily separated with resin made from the mode of production in this way, and fiber arranges in resin
In order, and obtained thermoplastic composite tube eliminates the stress produced between fiber and resin, the tensile strength of tubing and disconnected
Elongation is split to be greatly improved, and tubing thickness, stress distribution are uniform, and stability is strong, also improves the service life of tubing.
Need further exist for explanation is that fiber can be one kind or its group in polyester fiber, glass fibre or carbon fiber
Close, the form of fiber can be fiber line, fiber cloth or fibrofelt it is one or any between combine.Polyester fiber is to be poly- to benzene
Two ester fiber of dioctyl phthalate second, poly fiber, PTT Fiber, poly terephthalic acid-
The polyethylene terephthalate of 1,4- cyclohexanedimethylene terephthalates fiber, poly- two ester fiber of 2,6- naphthalenes diacid second and a variety of modifications is fine
At least one of dimension, glass fibre is E- glass fibres, C- glass fibres, high-strength glass fibre, AR glass fibres, A glass
At least one of fiber, E-CR glass fibres, D glass fibre, carbon fiber can be divided into polypropylene for carbon fiber by raw material sources
Itrile group carbon fiber, asphalt base carbon fiber, viscose-based carbon fiber, phenolic aldehyde base carbon fibre, gas-phase growth of carbon fibre, including it is therein extremely
Few one kind.
The above described is only a preferred embodiment of the present invention, being not the limitation for making other forms to the present invention, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Effect embodiment is applied to other fields, but every without departing from technical solution of the present invention content, the technical spirit according to the present invention
Any simple modification, equivalent variations and the remodeling made to above example, still fall within the protection domain of technical solution of the present invention.
