Definitions
- Plastic hollow body in particular plastic pipe
- the invention relates to a hollow plastic body, in particular a plastic tube.
- Plastic pipes are known in various embodiments. They serve, for example, the implementation of liquids and gases. But you can also fulfill building physics tasks or used for the passage of cables or the like.
- Pipelines made of conventional polymer materials have large wall thicknesses relative to standardized nominal diameters.
- the design of the wall thickness is based inter alia on the material properties, the respective operating pressure, the operating temperature, installation conditions, deformation resistance, expected service life etc.
- Large pipe wall thicknesses have disadvantages in terms of flow rate, pipe weight and material costs.
- the production rate of the tubes is also limited by the wall thickness.
- Plastic pipes with a pipe wall made of interconnected, cylindrical layers are known, for example, as sewage pipes from EP 0360 758 B1. All layers of the tube contain polyester resin, ie a duromer. While the inner layer consists solely of a cured polyester resin, the outer layer of the tube is formed from a mixture of a cured polyester resin and a filler, for example quartz sand. The layers extending between the inner and outer layers contain, in addition to polyester resin, different proportions of fillers and / or glass fibers.
- the known tube is produced by centrifugal casting, which is also described in EP 0 360 758 B1. This is referred to in the context of this application.
- the base materials namely the curable polyester resin, fillers and glass fibers are spun in different mass fractions to form the individual layers via a so-called feeder in a rotating die.
- the tube By curing the resin, the tube then contains its stability.
- pipes pipe sections
- the pipe diameter can be small (for example 10 or 30 cm), but also be a few meters.
- the number and composition of the individual layers may depend, inter alia, on the size of the tube and its use.
- the prior art outlines, by way of example, the differences between a "pressure tube”, through which a fluid is conveyed under pressure, and a "pressure-free tube", for example, the mentioned sewage pipe.
- Polyolefin pipes with reinforcing fibers of aramid or with a reinforcement made of steel wire belong to the prior art.
- the aim of the invention is to provide a plastic pipe of the type described, which has an advantageous ductility with high material strength, security against deformation and long-term strength, so that it can be used for a variety of applications.
- plastic pipes which consist of a plastomer.
- "Plastomer” is representative of undoped and therefore plastic or plastifiable thermoplastics, which differ from the "duromers” mentioned above, which are a generic term for dense-meshed and hard thermosets.
- such pipes made of thermoplastic materials such as polyvinyl chloride, polypropylene or polyethylene, however, have only a relatively low strength and are not particularly economical for larger pipes, such as those used in the municipal water supply and sanitation.
- Another disadvantage is the necessary large wall thickness.
- the invention provides in its most general embodiment a hollow plastic body, in particular a plastic tube, the wall of which is composed of interconnected, cylindrical layers, wherein at least one layer consists of a duromer and at least one further layer consists of a plastomer.
- a plastic pipe according to the invention can therefore be referred to as a composite pipe in which thermosetting layers alternate with plastomeric layers.
- thermosetting plastics can be synergistically combined with the advantageous properties of thermoplastics.
- thermosetting resin such as a thermosetting polyester resin may be used.
- the plastomer may be a thermoplastic of the following group: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyphenyloxide (PPO), polyphenylsulfide (PPS), polyphenylene sulfone (PSO, PES), polyimide (PI ), Polyamide (PA), polyoxymethylene (POM), polybutylene (PB), polyethylene terephthalate (PETP).
- PE polyethylene
- PP polypropylene
- PVC polyvinyl chloride
- PS polystyrene
- PPO polyphenyloxide
- PPS polyphenylsulfide
- PSO polyphenylene sulfone
- PI polyimide
- PA Polyamide
- PA polyoxymethylene
- PB polybutylene
- PETP polyethylene terephthalate
- the plastic tube like a conventional polyester resin spun plastic tube, is formed with a plurality of layers, for example 3 to 20 layers, with layers of a duromer alternating regularly or irregularly between layers of a plastomer or vice versa.
- the thickness of each layer can be between 0, 1 and 50 mm, it can be limited to ⁇ 10mm or ⁇ 2mm.
- the inner and outer layer of the tube consists of a plastomer.
- the outer plastomer layer provides good impact protection, the inner plastomer layer minimizes abrasion and is also safe for drinking water that is transported through the pipe.
- the invention is not limited to use different material pairings for the construction of the individual layers. Rather, further optimizations can be carried out simultaneously. These consist for example in that one or more layers have a reinforcement (reinforcement). Such a reinforcement may for example consist of thermoplastic and highly stretched bands. These tapes may be coated with a primer to optimize their bonding with the surrounding plastic material.
- the bands can be flat bands or profile bands. Alternatively or cumulatively, fibers can be used as a reinforcement. Such fibers may be cut fibers. They can be randomly distributed or ordered and distributed in the plastic material of the respective layer. It is essential that the fiber or strip material bonds with the surrounding plastic material.
- the tensile strength (at 23 ° C) of the reinforcing material, measured according to ISO 527, should be> 250 MPa.
- the elastic modulus of the reinforcement should be at least 1.5 times that of the reinforced layer, preferably at least> 5 or> 10 times greater.
- the reinforcement may also be helical, mesh or lattice-like, sieve-like or strip-like.
- the reinforcement material may be woven or braided. It may also, flat or profile part, consist of superimposed, connected strips or bands.
- a preformed reinforcing body can be placed on an already formed layer of the tube or pressed into it.
- at least one of the duromeric layers is reinforced or the reinforcement extends between two duromer layers.
- thermoplastic reinforcing materials for example, from highly stretched polyethylene.
- suitable are, for example, polypropylene, polyamide or other materials mentioned in claim 4.
- the reinforcement or reinforcement layer may also consist of a plurality of reinforcement elements, for example a plurality of meshes, and serve to form a plurality of layers of the plastic pipe.
- openings within the reinforcement or distances between adjacent reinforcement parts should be chosen so large that the corresponding plastic material can penetrate in viscous form and completely enclose the reinforcement.
- the "lattice spacing" is also to be chosen so that the material of the pipe wall withstands the maximum internal pressure during application.
- D layers containing a thermoset
- P layers containing a plastomer
- B means reinforcement (reinforcement).
- the reinforcement can run completely or partially in the inner or outer adjacent layer. 1st example: PDDBD -PDPPD
- the individual layers can be interconnected by force and / or material.
- Such a frictional connection can be achieved, for example, between adjacent D-layers easily by these D-layers are successively applied by spin coating, so that it comes in the subsequent curing of the thermosetting plastic to a material connection of adjacent layers.
- the technology of the spin process is known (eg EP 360758 Bl). This is referred to.
- a frictional connection between layers containing different plastics can also be achieved by applying an adhesion promoter between the two layers.
- adhesion promoters may be, for example, adhesive films or so-called melting films.
- adhesion promoters it is also possible to use chemical adhesion promoters, for example polymerisable polyesters or rubber derivatives. These can be applied as a sticky powder on the surface of a layer, for example, before the next layer is applied. Due to the development of heat during curing of thermosetting plastics, the adhesion of the adhesion promoters can be optimized.
- the adhesion promoter used is also maleic anhydride, which advantageously combines D and P or B layers.
- the connection of adjacent layers can also be effected by thermal surface treatment (heating) or high-energy radiation.
- the bonding substance may consist of a LLDPE (linear low density polyethylene) mixed with a PP (polypropylene).
- LLDPE linear low density polyethylene
- PP polypropylene
- At least one layer of a duromer may contain at least one of the following constituents: quartz sand, SiO 2 based filler, MgO, CaO, Al 2 O 3 , MgCO 3 , CaCO 3 , Al (OH) 3 , CaSO 4 , BaSO 4 , Talc, kaolin or mixtures thereof, glass fibers.
- Example I a P 1 -Dl-D 2 -B-D 3 -Pi-D 3 -Pi -P 2 -D 4
- D i Layer of one part by weight of cured polyester resin and three parts by weight of quartz sand.
- D 2 Layer of one part by weight of cured polyester resin and two parts by weight of calcium carbonate filler in a particle size ⁇ 0.3 mm.
- B Reinforcement made of a highly stretched PE tape with a cylindrical, lattice-shaped design, coated with a random terpolymer with acrylic ester and maleic anhydride.
- D 3 Layer of one part by weight of cured polyester resin and 0.3 parts by weight of glass fibers with a length ⁇ 60 mm.
- D 4 layer of cured polyester resin, wherein the polyester resin of the layer D 4 is different from the polyester resins of the other D layers as follows:
- the elastic modulus (determined according to ISO 527) of the layer D 4 is 200 MPa, while the modulus of elasticity of the remaining D layers is 2500 MPa.
- the elongation at break (according to ISO 527, ISO 178) is about 50% for the D 4 layer and only about 5% for the other D layers.
- a further P-layer (P 1) can advantageously follow on the inside.
- duromeric wall layers take over the load capacity of the pipe (the rigidity) and the loads acting on the pipe from the outside. Therefore, especially outer layers of duromers are important.
- a reinforcement of this kind in a neutral layer or in the inner layers can significantly increase the internal compressive strength.
- the internal pressure can be 20 bar and more.
- Inner and outer layers mean: this side and beyond the middle (neutral layer) of the wall thickness of the tube.
- the plastomeric wall layers especially if they are formed as outer and / or inner cover layer, offer protection against mechanical attacks. They have a favorable impact resistance and are abrasion resistant.
- the plastic materials are advantageous because of their drinking water suitability. But they are also resistant to chemicals, UV, light and temperature resistant.
- the D layers are applied according to the centrifugal method described above, the P layers can be integrated in different ways.
- the formation of the B-layers has already been shown.
- thermoplastic resin layer is formed by a tube, which is shrunk by means of a primer on a previously prepared thermoset layer.
- thermosetting plastic in a centrifugal process.
- This layer can still be “soft.”
- An extruded, pre-folded tube made of a thermoplastic material is then introduced into the die, after which the tube is "popped", resuming its cylindrical shape, which is dimensioned so that the outer surface bears against the inner surface of the previously formed thermoset layer is applied. If the outer layer is still “soft” (not hardened), the bond is particularly intense In this embodiment too, the connection between the D layer and the P layer can again be assisted by a bonding agent A next D layer can again be centrifuged be applied.
- the thermoplastic material is sprayed onto a previously formed layer. The spraying can be done both from the outside and from the inside, so as to form an outer or inner further layer.
- thermoplastic material is injected into an annulus between a previously formed thermoset layer and a spaced template. The template is then removed again.
- thermoplastic peripheral layer covering layer
- a fifth embodiment provides for shrinking or winding up a thermoplastic film onto an existing layer.
- the winding of a still plastic film or web can be done directly from the extruder to the existing layer.
- a thermoplastic jacket layer can be extruded directly tubular to a tubular body.
- thermoplastic layer to be applied by "sintering."
- the thermoplastic material is applied as a powdery material and then melted under the action of temperature.
- thermoplastic layers containing a thermoplastic with fillers or other components.
- other components include, for example, glass fibers, filaments or other reinforcing materials.
- the thermoplastic layers in particular an outer cover layer, can be foamed, so that at the same time a thermal insulating layer is produced.
- the surface of one of two adjacent layers may be profiled, for example studded, which promotes adhesion / anchoring.
- composite pipes have a high long-term internal pressure resistance, even with reduced wall thickness compared to plastic pipes according to the prior art.Also to emphasize the advantageous ductile properties of such a tubular body with sufficient radial and axial rigidity, also the diffusion tightness, fracture toughness and Resistance to chemical substances
- the wall thicknesses of the layers are calculated and adjusted according to the respective pipe requirements, as well as the type, number of layers and thickness of a possible reinforcement, for example the different mesh distances of a grid-like reinforcement can change the overall ductility of the pipe.
- the reinforcement can, if it has a cylindrical shape with openings, so a net-like shell structure, analogously to the second embodiment (as mentioned above) are introduced. After the folded cylinder has risen, the reinforcement can at least partially penetrate the still deformable layer of duro.
- the invention also provides the possibility of providing further functional intermediate layers, such as barrier layers to oxygen, water vapor, etc.
