Description
Technical Field
The invention relates to the technical field of thermoplastic fiber reinforced plastic composite sheets, in particular to a wide-width fiber net reinforced plastic laminated composite sheet for manufacturing ultra-large-caliber polyethylene pipelines with flared ends in a sectionalized mode.
Background
At present, thermoplastic continuous glass fiber reinforced polyethylene sheets produced at home and abroad are called thermoplastic glass fiber belts (or sheets), the width specification of the thermoplastic glass fiber belts is generally between 500 mm and 1000 mm, and the thermoplastic glass fiber belts are called narrow thermoplastic glass fiber belts. The width of the thermoplastic glass fiber tape with common specification is about 600 mm, and the thickness of the manufactured thermoplastic glass fiber tape is between 0.15 mm and 0.4 mm according to the diameter of the glass fiber. The sheet is mainly used for manufacturing fiber reinforced plastic pipelines, and is used by cutting thermoplastic glass fiber strips with a width of narrower (generally 50-160 mm). The unidirectional thermoplastic glass fiber tape is characterized in that continuous glass fibers are uniformly and parallelly distributed in the length direction, the angle between the continuous glass fibers and the length direction of the longitudinal tape is zero, and the unidirectional thermoplastic glass fiber tape is called zero-degree glass fiber tape, only bears longitudinal tension and does not bear transverse tension, and is mainly applied to manufacturing of spiral forward and reverse winding polyethylene reinforced pressure pipelines.
Fig. 1 shows a conventional fiber reinforced plastic pipe, which comprises an inner pipe 01, a glass fiber reinforced layer 02 coated on the outer side of the inner pipe 01, and a plastic layer 03 coated on the outer side of the glass fiber reinforced layer 02. The glass fiber reinforced layer is formed by winding a plurality of layers of zero-degree glass fiber belts on the outer side of the inner pipe 01 in a positive and negative staggered manner until reaching the target thickness, thereby meeting the requirement of the compression resistance of the pipeline.
The traditional production mode is that after the inner tube 01 is produced, the cut zero-degree glass fiber belts are used, a plurality of layers are spirally and positively and reversely staggered and wound on the outer side of the inner tube 01 along the axial direction of the inner tube 01, and the thermoplastic glass fiber belts are tightly fused together by heating and melting during winding, so that the thermoplastic glass fiber reinforced layer 02 is formed. The traditional production mode is only suitable for producing fiber reinforced plastic pipelines with small pipe diameters (the inner diameter of an inner pipe is generally 20-630 mm), and if a large-caliber fiber reinforced plastic pipeline (the inner diameter of the inner pipe is 1000-6000 mm) is to be produced, the single-piece spiral forward and backward winding mode has low efficiency and high energy consumption, and the large-caliber fiber reinforced plastic pipeline with a bell and spigot cannot be produced.
Through researches, the inventor provides a wide glass fiber net reinforced plastic laminated composite sheet with lateral side containing only transverse continuous fibers, and changes the winding mode of the sheet on an inner pipe, so that the efficiency of sectionally producing a large-caliber fiber reinforced plastic pipeline is improved by more than 10 times, the energy consumption is reduced by several times, the lateral side part contains only transverse continuous fibers and does not contain longitudinal continuous fibers, the fiber reinforced plastic pipeline with flares can be produced, and further the rapid production of sectionally producing the large-caliber fiber reinforced plastic pipeline is possible.
Disclosure of Invention
Therefore, the technical problem to be solved by the invention is to overcome the defects that the unidirectional zero-degree glass fiber tape in the prior art can only adopt a spiral positive and negative winding mode to wrap the inner pipe, so that the production efficiency is low, the energy consumption is high and a large-caliber fiber reinforced plastic pipeline with a bell and spigot cannot be produced, and therefore, the invention provides a wide glass fiber net reinforced plastic laminated composite sheet which can change the winding mode of a thermoplastic glass fiber sheet on the inner pipe, further can improve the winding efficiency, reduce the energy consumption and can produce the large-caliber fiber reinforced plastic pipeline with the bell and spigot.
The invention provides a wide fiber net reinforced plastic laminated composite sheet, which comprises a wide longitudinal sheet composite layer and a transverse sheet composite layer, wherein the wide longitudinal sheet composite layer and the transverse sheet composite layer are laminated with at least two layers in a mode of being overlapped and fused into a whole in a 90-degree staggered manner so as to form a laminated composite sheet;
the broad longitudinal sheet composite layer is provided with a longitudinal main body part and longitudinal side edge parts positioned at one side or two sides of the longitudinal main body part; the longitudinal main body part comprises a thermoplastic sheet and the longitudinal continuous fibers uniformly distributed in the thermoplastic sheet, and the extending direction of the longitudinal continuous fibers is consistent with the length direction of the laminated composite sheet; the longitudinal side edge portions are plastic sheets that do not contain the longitudinal continuous fibers;
the transverse sheet composite layer is overlapped and fused with the wide longitudinal sheet composite layer and comprises a thermoplastic sheet and the transverse continuous fibers uniformly distributed in the thermoplastic sheet, and the extending direction of the transverse continuous fibers is consistent with the width direction of the laminated composite sheet;
the length of the transverse sheet composite layer is basically the same as the width of the wide longitudinal sheet composite layer along the length direction of the transverse continuous fibers;
the longitudinal main body part and the transverse sheet composite layer are laminated and fused to form a laminated composite sheet netlike main body part;
the longitudinal side edge portions are laminated and fused with the transverse sheet composite layer to form laminated composite sheet side edge portions comprising only transverse continuous fibers.
As a preferable mode, when one side of the laminated composite sheet is provided with the laminated composite sheet side part, the width of the laminated composite sheet side part accounts for 5-15% of the width of the laminated composite sheet;
when the two sides of the laminated composite sheet are provided with the side edge parts of the laminated composite sheet, the width of any one side edge part of the laminated composite sheet accounts for 5-15% of the width of the laminated composite sheet.
As a preferred embodiment, the laminated composite sheet has a width of 2 to 30 m.
Preferably, the longitudinal continuous fibers and/or the transverse continuous fibers are one of inorganic fibers such as glass fibers, basalt fibers, carbon fibers, metal fibers, and the like.
Preferably, the thermoplastic sheet is a polyolefin-based plastic such as polyethylene or polypropylene.
The technical scheme provided by the invention has the following advantages:
the wide fiber net reinforced plastic laminated composite sheet comprises a wide longitudinal sheet composite layer and a transverse sheet composite layer, wherein the wide longitudinal sheet composite layer and the transverse sheet composite layer are laminated and fused into a whole in a 90-degree staggered and overlapped mode, and at least two layers are laminated and fused, so that the laminated composite sheet is formed.
The wide-width longitudinal sheet composite layer comprises a longitudinal main body part and longitudinal side edge parts positioned at one side or two sides of the longitudinal main body part, wherein the longitudinal main body part comprises a thermoplastic sheet and the longitudinal continuous fibers uniformly distributed in the thermoplastic sheet, and the longitudinal continuous fibers extend along the length direction of the laminated composite sheet; the longitudinal side edge portions are plastic sheets that do not contain longitudinal continuous fibers; the transverse sheet composite layer and the wide longitudinal sheet composite layer are overlapped and fused, and the transverse sheet composite layer comprises a thermoplastic sheet and transverse continuous fibers uniformly distributed in the thermoplastic sheet, wherein the extending direction of the transverse continuous fibers is consistent with the width direction of the laminated composite sheet; when the wide longitudinal sheet composite layer and the transverse sheet composite layer are overlapped and fused at 90 degrees, the length of the transverse sheet composite layer is basically the same as the width of the wide longitudinal sheet composite layer along the length direction of the transverse continuous fibers.
That is, the wide fiber net reinforced plastic laminated composite sheet formed by laminating and fusing the wide longitudinal sheet composite layer and the transverse sheet composite layer comprises a laminated composite sheet net main body part and a laminated composite sheet side part, wherein the longitudinal main body part and the transverse sheet composite layer are laminated and fused to form the laminated composite sheet net main body part, and the longitudinal side part and the transverse sheet composite layer are laminated and fused to form the laminated composite sheet side part.
After full lamination and fusion, the net-shaped main body part of the laminated composite sheet comprises a composite layer of plastic, crisscrossed longitudinal continuous fibers and transverse continuous fibers from the appearance; the side portions of the laminated composite sheet comprise composite layers of plastic and transverse continuous fibers.
The wide fiber net reinforced plastic laminated composite sheet is particularly suitable for manufacturing a large-caliber fiber reinforced plastic pipeline with an outer flaring, and in the concrete production, the net-shaped main body part of the laminated composite sheet is wrapped on the part with the consistent outer diameter of the pipeline in a hot-melt winding way, and the side part of the laminated composite sheet is wrapped on the outer flaring part of the pipeline in a hot-melt winding way; after the wide fiber net reinforced plastic laminated composite sheet material is hot-melt wound on the pipeline, longitudinal continuous fibers are wound around the circumference of the pipeline, and transverse continuous fibers are uniformly distributed along the axial direction of the pipeline.
The wide fiber net reinforced plastic laminated composite sheet material has wide width of 2-30 m (namely the width of a wide longitudinal sheet material composite layer, namely the total width of a longitudinal main body part and a longitudinal side edge part), is directly wound and coated on the outer wall of a flared plastic pipeline produced in a fixed length manner, wherein the width of a net-shaped main body part of the laminated composite sheet material is consistent with the length of a part with consistent outer diameter of the plastic pipeline; the width of the side portions of the laminated composite sheet is generally greater than the length of the outer flare of the plastic tubing.
Compared with the traditional method of adopting zero-degree glass fiber tape spiral forward and reverse staggered winding, the wide fiber net reinforced plastic laminated composite sheet has the advantages that the production speed is faster and is more than 10 times of the speed; the wide fiber net reinforced plastic laminated composite sheet can solve the problem of axial following winding of transverse continuous fibers at the outer flaring position, namely, when the laminated composite side edge part of the wide fiber net reinforced plastic laminated composite sheet is hot-melt wound on the outer wall of the outer flaring of a plastic pipeline, the transverse continuous fibers can change along with the outer wall of the outer flaring and can be finally uniformly wrapped on the outer wall of the outer flaring.

When the wide fiber net reinforced plastic laminated composite sheet material of the embodiment is continuously wound and coated to produce a large-caliber thermoplastic fiber reinforced plastic pipeline, the transverse continuous fibers 21 uniformly distributed on the transverse sheet material composite layer 2 are changed into axial parallel fibers of the pipeline, the pipeline is coated by the whole sheet, and the continuous fibers axially parallel to the pipeline can bear the axial tensile force of the pipe; the longitudinal continuous fibers 11 of the wide-width longitudinal sheet composite layer 1 become circumferential fibers of the pipeline after the pipeline is wound and molded, and the longitudinal continuous fibers 11 which are perpendicularly intersected with the transverse continuous fibers extending along the axial direction of the pipeline can bear the radial tension of the pipeline, so that the wrapped pipeline has excellent radial-axial bidirectional mechanical properties; the pressure pipeline manufactured by the laminated composite sheet has high internal bearing pressure, uniform radial and axial structural force of the pipeline, excellent mechanical property of the pipeline, obviously improved strength and rigidity of the product and long service life.
The wide-width fiber net reinforced plastic laminated composite sheet is particularly suitable for manufacturing a large-caliber thermoplastic fiber reinforced plastic pipeline with external flaring, and in the concrete production, the net-shaped main body part 3 of the laminated composite sheet is wound on a part with the consistent external diameter of the pipeline in a hot-melt way, the side part 4 of the laminated composite sheet is wound at the external flaring end of the pipeline in a hot-melt way, after the laminated composite sheet is heated and softened, the side part 4 of the laminated composite sheet is free from radial constraint of longitudinal continuous fibers 11, can wind the flaring end of a pipe with the variable external diameter, and enables the transverse continuous fibers 21 to be uniformly distributed at the flaring end of the pipe with the variable diameter along the axial direction.
With the help of the laminated composite sheet structure of the embodiment, for large-caliber pipeline production, the pipe can be processed in a sectional manner, bell and spigot design is adopted between two adjacent sections, the length of the part with the consistent outer diameter of each section of pipeline is matched with the width of the laminated composite sheet net-shaped main body part 3, the laminated composite sheet net-shaped main body part 3 is wound on the pipeline pressure-bearing main body part with the unchanged outer diameter, the laminated composite sheet side part 4 is wound on the flaring end part with the changed outer diameter, after the sectional processing is finished, the flaring end and the pipeline outer layer are required to be continuously compositely wound on corresponding structural layers, and the installation of a long-length large-caliber pressure pipeline is completed through bell and spigot connection.
The wide fiber net reinforced plastic laminated composite sheet of the embodiment has wider width, can be made into 2-30 m wide, and is directly wound and coated on the outer wall of a plastic pipeline with a flaring end produced at a fixed length, wherein the width of a net-shaped main body part 3 of the laminated composite sheet is consistent with the length of a part with the consistent outer diameter of a polyethylene pipeline; the width of the laminated composite sheet side portions 4 is generally greater than the length of the outer flare of the polyethylene tubing.
Unlike the traditional method of winding zero-degree glass fiber belts in a positive and negative staggered way, the laminated composite sheet material of the embodiment adopts direct whole continuous cladding, thereby greatly improving the winding efficiency, reducing the energy consumption, enabling the industrial production of the large-caliber fiber reinforced plastic pipeline to be possible, and the wrapping speed is 10 times or more than the original winding type wrapping speed; the wide fiber net reinforced plastic laminated composite sheet of the embodiment can solve the problem of unbound winding of continuous axial fibers uniformly distributed at the flaring end, and when the side edge part 4 of the laminated composite sheet is wound on the outer wall of the outer flaring of a pipeline, the transverse continuous fibers 21 can be changed along with the outer wall of the outer flaring and finally uniformly and axially arranged and wrapped on the outer wall of the flaring end.
