Description

The present invention relates to a laminate of reinforcing fibers and pulp, a process for producing this laminate, the use of the laminate, a transport pallet from the laminate and a packaging system comprising this transport pallet.

Packaging systems and packaging modules have become indispensable in today's everyday life, as these are available to freight forwarders and trading companies in standardized proportions and play a major role in goods transport. Due to their standardized dimensions, they can be picked up and moved, for example by pallet trucks or forklifts. The goods to be transported, such as solar cells, are stacked on top of these packaging systems, such as europallets. The previously used mostly Euro-wooden pallets consist of several longitudinally arranged boards, which are interconnected with cross woods and rest on stud feet, which in turn have for further stabilization crossbeams and longitudinal beams. The production of such Euro wooden pallets is made of good grown wood and is therefore relatively expensive and time consuming. It should also be remembered that Euro-pallets have a high intrinsic weight, which limits their transport capacity and increases their moisture absorption over time.

From the EP 01882641 A1 is a transport pallet is known, which is composed essentially of used cardboard tubes.

DE 38 10 089 A1 describes a stacking pallet of stone or glass fibers and a binder.

DE 885 153 describes a laminate of layer packages of a pulp, which is alternatively either paper or glass fiber in the entire layer body.

DE 1 694 281 describes a composite of 6 layers of cellulose with a surface layer of glass paper obtained by depositing glass fibers.

DE 26 42 168 describes a paper material containing glass fibers for reinforcement.

DE 32 10 360 A1 especially in claim 6 describes a layer of glass fibers sandwiched between two layers of paper.

DE 698 19 549 T2 describes a high pressure laminate of a single fiberglass mat with an adjoining layer of kraft paper.

DE 34 16 940 A1 describes a paper in which glass fibers are incorporated.

DE 31 15 754 A1 describes a laminated sheet material in which a bundle of glass fibers can also be interposed between two layers of paper material.

Heretofore, cellulose fibers, such as paper, have been reinforced with glass fibers, for example to increase the tensile strength in the direction of the paper or also the tear resistance. So far, there have been only considerations to integrate individual layers of glass fibers in an entire laminate. Unless hitherto cellulose fibers have been used as material for transport systems such as pallets, the stability of the pallets has hitherto been attempted to be optimized in that the cardboard structures had to be elaborately designed in three dimensions. So far, for example, no compressive strengths have been achieved which have the compressive strength of normal European softwood of grade 2 ( DIN 1052 / 4.88 ) to reach. In the case of load on pressure parallel to the fiber, a maximum compressive strength of 0.85 kN / cm ^{2 can} build up in the case of this standardized softwood in the event of load, before failure can occur.

Object of the present invention is therefore to provide a material that allows for a much lighter transport systems that reduces moisture absorption and on the other hand has a much higher compressive strength and stability than previously used in transport systems materials such as softwood or plastics.

This object of the invention is achieved in a first embodiment by a laminate of at least 4 layers, wherein at least two reinforcing fiber layers 1 at least 30 wt .-% reinforcing fibers or reinforcing fiber reinforced plastic and at least two pulp layers 2 at least 30 wt .-%, wherein the reinforcing fibers are selected from glass fibers, carbon fibers, steel fibers, aramid fibers and / or ceramic fibers.

With the laminate according to the invention can be used as a material for example transport systems 11 like pallets 5 a weight saving of up to 70% compared to wooden pallets with significantly improved compressive strength (more than 1.45 kN / cm ² possible) achieve. The stability and tear strength or maximum tensile force is significantly improved, for example, compared to wood with the same material thickness. In addition, the laminate according to the invention absorbs much less moisture than the previous wooden pallets.

All features disclosed below are also disclosed in any combination with each other, if this makes sense and is not explicitly excluded.

Advantageously, the pulp is selected from waste paper, paper, cardboard and / or cardboard. As a result, the laminate according to the invention can be produced particularly inexpensively.

The layers of the same type are advantageously not directly adjacent to one another and particularly preferably alternate. It has been found that the material properties of the different layers can complement each other so well and particularly pressure-resistant and tensile laminates are obtained.

The laminate has, for example, an odd number of layers. This can be done with alternating reinforcing fiber layers 1 and pulp layers 2 the same type of layer may be provided on the outside of the laminate. Preferably, the laminate of the invention is constructed so that the two outermost layers of the laminate pulp layers 2 are. Overall, the laminate according to the invention has, for example, at least 6 and independently up to 81 layers, in particular 9 to 51 layers, very particularly preferably 12 to 24 layers. If the number of layers is too small, the flexural strength and compressive strength may be too low for applications such as transport pallets 5 come. If the number of layers is too large, the overall behavior with respect to compressive strength or load-bearing capacity only minimally changes, so that the additional effort due to more layers is not justified. The laminate according to the invention preferably has at least 11 layers in total, of which 6 are pulp layers 2 and 5 Layers of reinforcing fibers 1 on.

For example, a reinforcing fiber layer is included 1 according to the present invention at least 50 wt .-% reinforcing fibers or reinforcing fiber reinforced plastic. In particular, it consists of it. Regardless of this, and likewise the pulp layer 2 According to the present invention, for example, contain at least 50 wt .-% pulp and in particular consist of pulp.

At least one of the reinforcing fiber layers according to the invention 1 advantageously has a mat of glass fibers, in particular in the form of a nonwoven or a fabric. Regardless of and just as preferred, at least one reinforcing fiber layer 1 a mat made of glass fiber reinforced plastic, in particular as a non-woven or as a tissue on. Most preferably, in the same laminate according to the invention some reinforcing fiber layers 1 Mats of glass fibers and of which different reinforcing fiber layers Mats of glass fiber reinforced plastic on. The matrix of the glass fiber reinforced plastic may be, for example, polyester resin, epoxy resin and / or polyamide. The fiber volume fraction in the glass fiber reinforced plastic can be, for example, between 50 and 70 wt .-%. The layer thickness of the reinforcing fiber layer 1 is advantageously between 0.1 and 0.8 mm. If the layer thickness is below the range, then for some applications, no sufficient improvement, for example, the compressive strength is observed. If the layer thickness is above this range, increased brittleness of the overall laminate may occur.

For example, between a pulp layer 2 and a layer containing a glass fiber mat or a mat of glass fiber reinforced plastic 1 also a mat of aramid fiber (for example Kevlar ^® ) 1 be provided.

The layer thickness of the pulp layer 2 independently thereof is advantageously in a range of 0.1 to 0.9 mm. If the layer thickness is too much below this range, a decrease in tensile strength may be observed in certain applications. With a layer thickness above this range, it may come in some applications to reduce the compressive strength.

Preferably, the layers are interconnected with a binder. This binder is, for example, an adhesive, in particular a one-component adhesive or two-component adhesive. By using a binder, the individual layers of the laminate can be reliably and fully interconnected. The binder is, for example, water-soluble and in particular a binder based on bisphenol A.

The total thickness of the laminate according to the invention is advantageously in the dried state in a range between 5 and 10 mm. With a total thickness below this range, some applications, such as for example transport pallets, may under certain circumstances result in too low a bearing strength. With a total thickness above this range, some applications, especially with more complicated three-dimensional structures, can no longer be realized with this technology.

The proportion of binder in the laminate of the invention is advantageously in a range of 0.1 to 10 wt .-%. Irrespective of this, the proportion of pulp in the laminate according to the invention is advantageously in a range from 30 to 60% by weight, in particular less than 50% by weight. Independently of this, the proportion of the reinforcing fibers or of the reinforcing fiber-reinforced plastic in the laminate according to the invention is advantageously in a range from 30 to 69.9% by weight. In a particularly preferred embodiment, the laminate according to the invention comprises 40 to 60 parts by weight of pulp, 20 to 40 parts by weight of reinforcing fibers and 10 to 30 parts by weight of reinforcing fiber-reinforced plastic. At this indicated weight ratio, the reinforcing fibers of the reinforcing fiber reinforced plastic do not count as parts by weight of the reinforcing fibers. Glass fiber reinforced plastic, also known as "fiberglass", is particularly preferably used as reinforcing fiber-reinforced plastic. Preferably, the laminate according to the invention is painted on the outside. For this purpose, it is particularly preferably first primed and independently thereof, more preferably several times, in particular twice. For this purpose, lacquers based on polyurethane, PVC or acrylic can be used. The thus, for example, painted on the outside laminate can be waterproof and / or airtight. For example, the paint can also be used as the binder. By painting the moisture absorption can be reduced to less than 2 wt .-% (at 10 minutes in boiling water). A lacquer can be used in high dilution with, for example, at least 99.5% by weight of solvent, in particular at least 99.9% by weight of solvent, the solvent being in particular water.

In a further embodiment, the object underlying the invention is achieved by a method for producing a laminate according to the invention, characterized in that a total of at least 4 layers selected from reinforcing fiber layers 1 and pulp layers 2 after having at least one of the overlapping surfaces of the layers previously provided with binder, and then compressing the resulting laminate.

Preferably one brings alternately reinforcing fiber layers 1 and pulp layers 2 in contact with each other. As a result, a particularly pressure-resistant and tensile laminate can be obtained.

The binder is advantageously sprayed on, since in this way a uniform and full-surface distribution of the binder can be ensured.

When contacting the various layers, it is advantageous to use paper having a temperature in the range of 40 to 110 ° C, independently of which glass fibers having a temperature in a range of 55 to 120 ° C and independently binders having a temperature in the range of 60 up to 100 ° C. For example, the temperature of the binder may be selected to be higher than the temperature of the layers. It has surprisingly been found that outside of these temperature ranges, the laminate can not otherwise be deformed or embossed so well immediately after the compression.

During the compression, the total thickness of the laminate is preferably reduced by 2 to 10%. Pressing below this range may result in defects due to lack of contact between the layers. Pressing above this area can destroy the structures within the individual layers, which may lead to a decrease in the tensile strength or even the compressive strength.

For the reinforcing fiber layers 1 In the method according to the invention, glass fiber mats and / or mats made of glass-fiber reinforced plastic are preferably used. These mats have, for example, a basis weight in a range of 100 to 500 g / m ² , in particular in a range of 200 to 400 g / m ² . The pulp layer employed in the process according to the invention is, for example, waste paper or paperboard. The pulp layer 2 in this case preferably has a basis weight in a range of 300 to 900 g / m ² , in particular in a range of 500 to 700 g / m ² . At these basis weights both for the reinforcing layers 1 as well as for the pulp layers 2 It has been found that by this means particularly pressure-resistant and tensile laminates according to the invention can be obtained.

The resulting laminate is dried after being pressed, for example. This can - even just in advance - in a vacuum drying plant, especially for a period of up to 20 minutes, take place. The residual drying or drying can take place at room temperature for several hours or even several days. The moisture in the laminate can then be 6 to 12.

For example, the resulting laminate is also painted, especially after drying. It is particularly preferable to carry out the coating in an immersion bath, since this makes it possible to ensure that the entire surface of the laminate according to the invention is lacquered. This is important, for example, in order to be able to use the laminate in applications in free weathering. As a paint For example, an acrylic-based paint, PCV-based or polyurethane-based paint can be used.

After painting or after drying, the resulting laminate may be heated at an air temperature in a range of 200 to 500 ° C for a period of time in a range of 2 to 20 seconds. Subsequently, for example, the laminate may be at a temperature of less than -50 ° C at least at the surface for a period in the range of 0.1 to 5 seconds, in particular 0.5 to 1.25 seconds, for example, with liquid nitrogen cooling down.

In a further embodiment, the object underlying the invention is achieved by the use of the laminate according to the invention for the production of tubes, packaging systems, transport systems, parts of land, water or air vehicles, furniture and parts of buildings. In particular, the laminate according to the invention can be used for the production of engine shutters or bullet-proof doors.

In a further embodiment, the object underlying the invention is achieved by a tube 3 , at the wall of the tube 3 consists of the laminate according to the invention.

In a further embodiment, the object underlying the invention is achieved by a method for producing the tube according to the invention 3 in which one carries out the inventive production process of the laminate according to the invention with a conventional spiral winding machine.

In a further embodiment, the object underlying the invention is achieved by a plate 4 , which consists of the laminate according to the invention.

The wells 6 can be parallel to an outer edge of the plate 4 over the entire length of the plate 4 in this direction. The crossbars 7 can be perpendicular to the wells 6 be arranged. But it may also be advantageous that the angle of a cross-beam 7 to a deepening 6 deviates more than 10 ° from 90 °. This can also be beneficial for all angles between depressions 6 and crossbeams 7 be. The support feet 9 may be from tubes of the invention 3 be shaped. The crossbars 7 and regardless of the wells 6 in the plate can be half round. The recesses 8th can be designed according to form-fitting or non-positive. The recesses on the support feet 13 are for the crossbeams 7 advantageously a wall thickness deeper than the recesses 13 for the wells 6 the plate 4 , The edges of the recesses of the support feet 13 to the upper edge of the support feet 9 are rounded, for example. Regardless, the edges may have recesses of the crossbars 8th for receiving the wells 6 the plate 4 be rounded at the transition to the upper edge of the crossbeams. The size of the pallet 5 can be freely designed in principle. That's how the palette works 5 For example, have any size as desired or the size of the standard Euro, US, chemical or container pallets. The transport pallet according to the invention 5 For example, it can have at least two crossbeams 7 and regardless of two wells 6 exhibit. It can, for example, two or three crossbeams 7 and of it completely independent also two or three wells 6 be provided. Unless the crossbeams 7 and / or the depressions 6 semicircular, the outer radius can be in a range of 5 to 7 cm. Moreover, the transport pallet according to the invention 5 be rectangular.

Advantageously, the transport pallet according to the invention 5 not only rectangular but also points to the peripheral boundary of the plate 4 on at least two of the four sides one perpendicular to the plate 4 and from the feet 9 aloof edge 10 on. As a result, in contrast to previously used Euro pallets and other standard pallets, the cargo can be secured against slipping.

The edge 10 is preferably 3 to 50 cm high, in particular 8 to 12 cm high. The edge 10 is preferably integrally formed, in particular for example by means of a manufacturing plant for cardboard edge protection around the plate 4 integrally formed. If only two of the four sides with a border 10 are provided, these edges are 10 for example, opposite. In particular, however, all four sides of the plate 4 with a border 10 Mistake. As a result, the cargo in any of the directions of the transport pallet 5 slip.

The wells 6 the plate 4 extend for example also in the edge 10 , The wells 6 can therefore, for example, with the rest of the edge 10 folded up or folded over together. To avoid tension, can be equal to the folded edge 17 over the length of the depression 6 a hole can be provided.

The pallet according to the invention 5 For example, it consists of two modules, one module through the plate 4 with the wells 6 and the other module through the support feet 9 with the crossbars 7 is formed. The second module allows the support feet 9 with the crossbars 7 be glued. Alternatively, all components of the pallet can be glued together.

The transport pallet 5 and the stacking plates 12 are advantageously with cones 15 over the edge 10 stand out and on the inside of the edge 10 are formed. It is particularly preferred if the stacking plates 12 directly below the pin 15 a hole 16 in the size of the base of the pin 15 in the wall of the stacking plate 12 exhibit. The cones 15 advantageously have a rectangular base. In particular, the pins have 15 a length in a range of 2 to 10 cm. For example, the cones can 15 over half the length to the edge 10 be formed and with respect to the other half of the pin 15 over the edge 10 protrude. The cones 15 For example, they may have a width in a range of 1 to 5 cm. The thickness of the pins 15 may independently be in a range of 0.2 to 2 cm, for example. Particularly preferred are the pins 15 as thick as the wall thickness of the edge 10 , In particular, the pins 15 from the laminate according to the invention. Unless the footprint of the transport pallet 5 is rectangular, it is particularly advantageous that on the longitudinal side in each case two pins 15 and on the short sides in each case a pin 15 are provided. The cones 15 can also have multiple stacking plates 12 and the transport pallet 5 extend, the pins 15 then not firmly against the wall 10 the transport pallet 5 or stacking plate 12 are formed, but by several stacking plates 12 except for the transport pallet 5 be pushed through.

embodiments

Example 1: Basic Example for the Production of Inventive Laminate

Waste paper with a basis weight of 600 g / m ² is alternately laid on top of each other with woven glass fiber mats having a basis weight of 300 g / m ² or commercial mats made of glass fiber reinforced plastic with a weight per unit area of 300 g / m ² , after the uppermost surface with a two-component adhesive was sprayed. The two-component adhesive used was the T / 440 product from SASPAS SRL based on bisphenol A. The layers were laid on top of each other so that the first and the last layer is a layer of waste paper. When the various layers were superposed, the temperature of the waste paper was 60 ° C, the temperature of the glass fibers and the glass fiber reinforced plastic was 60 ° C, and the temperature of the binder was 70 ° C. Subsequently, the laminate was pressed, so that the layer thickness has been reduced by 5%. After drying the resulting laminate, the laminate was painted by dip coating with the paint Acripac 1589 SASPAS SRL. When applying the paint was the Temperature of the paint about 20 ° C. Subsequently, the coating was dried at 25 ° C for about 15 min. Then another 5 min. Were waited. Then the laminate according to the invention was again painted as described above. Before the first painting, a commercially available primer such as the product Continut from ASPAS SRL was applied and dried for 30 minutes at room temperature before the first coating.

Example 2: Production of a tube according to the invention from laminate according to the invention

The laminate according to the invention was produced as described, for example, in Example 1 using a commercially available spiral winding machine. A total of 11 layers were applied to each other. Layers of waste paper and commercially available fiberglass mats were always applied alternately. In this case, instead of the outermost and the innermost glass fiber mat in each case a commercially available mat made of glass fiber reinforced plastic was used. The tubes had a wall thickness of 8 mm before compression and 7.6 mm after compression and an outside diameter of 14 cm. The dried and painted tubes showed a compressive strength perpendicular to the tube axis of 1.45 kN / cm ² .

Example 3: Production of boards according to the invention from laminate according to the invention

As already explained in Example 1, a plate according to the invention was produced. A total of 13 layers were applied to each other. The outermost layers were each recycled paper. Always alternately old paper and glass fiber mats were applied to each other. Only the two outermost glass fiber mats and the two innermost glass fiber mats were replaced by mats made of glass fiber reinforced plastic (cf. 2 B ). The lacquered plates were boiled in water for 10 minutes and, with a plate weight of 6.2 kg, only contained 120 g of water.

In one variant, a layer of a mat of woven aramid fibers ( ^Kevlar® ) was provided in the middle of the layers. An entire magazine was then fired on the plate with a Kalashnikov automatic rifle. Not a single projectile broke through the plate.

Example 4 Production of a Transport Pallet According to the Invention from Inventive Laminate

A 110 × 160 cm well plate was obtained by first preparing a plate according to Example 3 and, before drying and painting, embossing two semicircular wells having an outer radius of 5 cm into the plate lengthwise with a press. One depression was provided along opposite longitudinal edges at a distance of 20 cm from the outer edge of the plate. Subsequently, cones (2 × 1 × 10 cm) as in 3 shown schematically and cones as in 3 shown formed on the plate by gluing. Subsequently, with the help of a manufacturing plant for cardboard edge protection along the in 3 formed fold lines 10 cm high edges and joined together at the edges with the punched.

The crossbars were obtained in such a way that first tubes were produced and these were subsequently cut in half lengthwise. Subsequently, recesses in the cross members were provided at a distance of the recesses in the plate according to the invention to record the plate accordingly. Support feet were provided below the crossings of the crossbeams with the indentations. These support feet were also made like the tubes of the invention. However, the support legs were provided with recesses at the top so that these recesses could receive the cross members and recesses of the plate, as shown in FIG 1 is shown.

These pallets were thrown at 30 km / h on an iron wall.

After 20 attempts, none of the pallets were broken.

Example 5 Production of the Packaging System According to the Invention from Inventive Laminate

The packaging system was basically similar to the transport pallet in Example 4 itself. For the stacking plates, however, similar to the transport pallet but without recess as in 3 a sheet of laminate punched and folded accordingly and provided with appropriate pins. The resulting stacking plates could be easily stacked on the transport pallet and stacked on each stacking plates.

The pins of the lowermost transport pallet or overlying stacking plates were respectively inserted into the hole in the wall of the overlying stacking plate so that the stacked stacking plates could not slip relative to each other.
