Abstract
The invention discloses a reinforced thermoplastic plastic pipe which is relatively light in weight and is largely increased by pressure resistant performance, which comprises an inner layer pipe and an outer layer pipe. The reinforced thermoplastic plastic pipe is characterized in that a reinforced layer is further arranged between the inner layer pipe and the outer layer pipe, and the reinforced layer is wound by at least two layers of basalt fibers which are treated by plasma. The weight of the reinforced thermoplastic plastic pipe is only the one-quarter of a steel pipe, pressure resistant performance is greatly increased, the pipe can bear 800 Pa pressures, and is long in service life and strong in erosion resistance, besides, the plastic pipe can be processed into a pony roll in hundreds of meters, and is more convenient in paving and less in connector. The plastic pipe can be widely applied to conveying crude oil, acid natural gas and the like.
Description
Technical field
The present invention relates to a kind of reinforced thermoplastics pipe.
Background technique
The purposes of reinforced thermoplastics pipe (be called for short RTP pipe) more and more widely can be used at present the place that some have specific (special) requirements, for example at pressure up to conveying crude oil under the 100bar and sour rock gas (sourgas) etc.At present a kind of reinforced thermoplastics pipe that uses comprises the inner tube and the external pipe of being made by high-density polyethylene material (HDPE), in inner tube with locate to be provided with between layer pipe reinforcing material that is made of steel band, steel wire, glass fibre or aramid fibre.Its shortcoming of tubing of making as reinforcing material with steel band or steel wire is that weight is big, and it is all not too convenient to transport, construct; Its shortcoming of tubing of making as reinforcing material with glass fibre or aramid fibre is that withstand voltage properties is not high, can not satisfy some specific (special) requirements.
Summary of the invention
The technical problem to be solved in the present invention is: the reinforced thermoplastics pipe that a kind of weight is light, withstand voltage properties is largely increased will be provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: described reinforced thermoplastics pipe, comprise inner tube and external pipe, be characterized in: also be provided with enhancement layer between inner tube and external pipe, enhancement layer is entwined by the plasma treated basalt fibre of two-layer at least process.
The further technological scheme of the present invention is: the winding direction of the basalt fibre of above-mentioned adjacent two layers is opposite.
Above-mentioned basalt fibre is the basalt fibre through carrying out grafting and coating again with resin after the plasma treatment.
Above-mentioned inner tube and external pipe are made by high-density polyethylene material.
Continuous basalt fiber (Continuous Basalt Fibre is called for short CBF) be with natural volcano extrusive rock as raw material, the continuous fiber of making through melt spinning.It has that mechanical property is good, high and low temperature resistance good (can continuous operation in-269～700 ℃ of scopes), cost performance height, acid-fast alkali-proof, anti-ultraviolet property is good, environmental resistance is good, good insulation preformance, hygroscopicity are low, radioresistance, good advantages such as wave penetrate capability.Gummed effect between the same organic basis material of the basalt fibre after the plasma treatment (as resin) interface has obtained large increase.
Advantage of the present invention is: the weight of described reinforced thermoplastics pipe only is 1/4 of steel pipe weight, and withstand voltage properties has also had large increase, can bear the pressure of 800 handkerchiefs, long service life, and corrosion resistance is strong; And this kind tubing can be processed into long the coiling of hundreds of rice, and construction is laid convenient, and joint still less.
Description of drawings
Fig. 1 is the structural representation of reinforced thermoplastics pipe of the present invention;
Fig. 2 is a process flow diagram of using the plasma treatment basalt fibre described in the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done to describe further.
As shown in Figure 1, described reinforced thermoplastics pipe, comprise inner tube 11 and external pipe 31, inner tube 11 and external pipe 31 are made by high density polyethylene (HDPE) (HDPE) material, are characterized in: also be provided with two-layer at least by plasma treated and carry out the enhancement layer 21 that the basalt fibre of grafting and coating is entwined with resin again between inner tube 11 and external pipe 31.In concrete working process, when on inner tube 11, twining basalt fibre, can heat inner tube 11, when twining, can make the resin melted by heating on basalt fibre surface like this, make between itself and the inner tube 11 and can be compound well between the adjacent two layers basalt fibre, basalt fibre is wrapped in inner tube 11 outsides from level to level with spiral helicine canoe, and make the winding direction of basalt fibre of adjacent two layers opposite, the winding angle of basalt fibre can be chosen between 20 °～80 ° during winding; After twining end-of-job, carry out online coating last layer high-density polyethylene material (HDPE) protective layer by the extruder die head again, constitute external pipe 31.
Need to prove, with plasma basalt fibre is handled and to be adopted process route shown in Figure 2, that is: pending basalt fibre 1 is passed vertically between the sparking electrode 21 in the RF plasma generator 2, be provided with the sample pool 4 of a splendid attire resin solution in the back of RF plasma generator 2, described resin is selected from ethylene-vinyl acetate, polyvinylbutyral, SIS, polymethylmethacrylate, TPU(Thermoplastic polyurethanes), polyester elastomer, epoxy resin, phenolic resin, urea formaldehyde resin etc., use gasoline during work, anhydrous alcohol, it is 2～15% solution that the acetone equal solvent is mixed with concentration with resin dissolves, and this resin solution is contained in the sample pool 4.Basalt fibre 1 after the process plasma treatment is under the guiding of four press-roller devices 3, pass the sample pool 4 and the impregnated with resin solution that are loaded with resin solution, utilize resin that basalt fibre 1 is carried out grafting and coating, go out sample pool 4 then, an automatic winding machine 6 is arranged at the rear portion, basalt fibre 1 after handling can be carried out online rolling, regulate the Trace speed of basalt fibre by the rotating speed of regulating Scroll.Regulate the distance between sample pool 4 and the winder 6, volatilized fully with the solvent on the basalt fibre 1 that guarantees impregnated with resin solution, a heating equipment 5 can also be installed between them, be volatilized fully to make the solvent on the basalt fibre 1 as far as possible.During work, connect power supply, make RF plasma generator 2 proper functioning, regulating plasma discharge power is 500W, the distance of regulating between two sparking electrodes 21 is 5 millimeters, makes it produce high-octane, uniform plasma by the dielectric barrier discharge mode under normal pressure.In the time of between the basalt fibre process plasma discharge electrode, its surface obtains handling.Regulate the rotating speed of Scroll, the Trace speed that makes basalt fibre is 30 meters/minute, can guarantee like this basalt fibre by the time of plasma treatment about 8 seconds, make it to be subjected to sufficient processing.Be subjected to abundant infiltration through the basalt fibre after the plasma treatment 1 through resin solution, online then drying is at last by winder 6 rollings.
After with plasma basalt fibre being handled, can overcome the inertia on basalt fibre surface, reduce its wetting angle, make the basalt fibre surface obtain effective etching and form active group, thereby improve the gummed effect between its same organic basis material (as resin) interface greatly.The purpose that plasma treated basalt fibre is carried out grafting and coating with resin more immediately is the activity that keeps the basalt fibre surface.
