Definitions
- the invention relates to a special binder mixture for production of nonwoven fabrics, and processes for their production. Farther are the prepregs made from the nonwovens and binders described.
- nonwovens are widely used in industry. These are nonwovens made of different types of fiber, that can be mixed with binders. From these non-woven fabrics then preliminary products can be produced, the so-called prepregs, which are then molded with the appropriate processing tools, cured and, if necessary, assembled. It is also possible directly from the fibers. and the company corresponding to the binder powders to manufacture servo endless goods. Find these molded parts or planware widely used. In the automotive industry, these are Products for example as molded parts, e.g. as insulation material for bonnets, Wheel arches or trunk insulation used. Another area of application is the use as planware, e.g. as insulation in washing machines, Tumble dryers or speakers, in sound absorbing Walls.
- planware e.g. as insulation in washing machines, Tumble dryers or speakers, in sound absorbing Walls.
- Nonwovens with binder powder are known.
- the fiber material e.g. in a fiber mixing chamber, homogenized, and on a Conveyor belt stored as a loose layer of fibers.
- the binder mixture is then applied to the fiber material e.g. with metering rollers or vibrating channels applied. Then the fiber / binder mixture in a closed system using an air flow swirled and mixed homogeneously.
- the homogeneous mixture of fiber and Binder powder is deposited to form a continuous fleece.
- the components this mixture can be done either by gentle heating and then Cooling are glued together, creating the prepregs or it is manufactured sheet or roll goods that are already complete is cured.
- the prepregs are not yet fully cured, are however stable in storage. After processing into the final one Shape, these prepregs are exposed to heat at up to 210 ° C thermally cross-linked, whereby three-dimensional thermosetting molded parts be preserved.
- JP-A-55-148266 describes a molded part made of nonwoven fabric, which is under Use of synthetic fibers, powder curl and resin will be produced.
- the object of the present invention is to provide a binder mixture
- a Another task is to determine the proportion of harmful substances to lower. These binder mixtures must meet the usual requirements in the manufacture of nonwoven molded parts and thereby cured, stable molded parts result, which the different purposes can be adjusted.
- Powder coatings are increasingly used in the coatings industry. These have the advantage that a solvent-free application process is possible. This can significantly reduce emissions to the environment become.
- the application processes for powder coatings have Disadvantage that a significant proportion of the powder does not affect what is to be coated Object arrived.
- These powders are in the paint booth collected as a so-called overspray. Powders are in their grain size distribution and sensitive in purity. So this overspray be disposed of as waste.
- the crushed paint powder extrudates are ground. At This grinding process produces fine dust, which is disruptive in the painting process. Therefore, this dust is largely removed. That dust is difficult to reprocess and must be disposed of as special waste become.
- the fibers that can be used for the various non-woven fabrics are concerned woven, matted or mixed fibers.
- the fibers are made from the known materials, e.g. natural, organic and inorganic Fibers. Examples are glass fibers, rock wool fibers, Polyester fibers, acrylic resin fibers, polyolefin fibers, wool fibers, cotton fibers, Flax fibers or the like. Textile fibers are preferred, especially cotton fibers, e.g. Fiber waste from the textile industry, used. These fibers or the non-woven fabrics from them are in industry known.
- the processes with which they are produced are also known can be. This can be done, for example, by weaving or felting happen.
- the resulting nonwovens should essentially be dry, they can be impregnated with additives if necessary.
- phenolic resins that can be used in the mixtures according to the invention
- these are the usual reactive phenolic resins that have been around for a long time are known in the industry.
- these are reactive, Non-crosslinked powdered phenolic resins containing OH groups.
- Such resins are already used to manufacture molded parts from nonwovens used.
- phenolic resins based on Phenol and formaldehyde such as, for example, as resols or novolaks are known to be used.
- These can be possible crosslinkers Resins contain condensation products of formaldehyde.
- the reactivity of the phenolic resins is also determined by the type and amount of the used Crosslinker determined.
- a crosslinking reaction generally occurs between 120 ° C and 222 ° C.
- the resins are generally in powder form. Suitable grain sizes are, for example, between 0.1 and 500 ⁇ m, preferably between 2 and 150 ⁇ m, particularly preferably between 10 and 60 ⁇ m.
- the grain sizes of the powder coating waste used are, for example in the same range as that of the resins and are preferably between 1 to 300 ⁇ m, particularly preferably between 10 and 60 ⁇ m. Become powder paint waste used, their grain sizes for the desired application are too small, it is possible to bake larger grain sizes to get the particles.
- the powder coating wastes which can be used according to the invention are those of the customary ones known powder coatings based on epoxy resins, polyester resins, polyurethane resins or acrylic resins. This powder coating waste is falling for example as overspray from paint booths or as incorrect batches in the manufacture of powder coatings. It is also possible that filter dust collected and used, as well as residues from the Grinding the powder.
- the powder coating waste which can be used in the mixture according to the invention are not yet networked. They contain reactive groups such as Carboxyl groups, epoxy groups, hydroxyl groups, amino groups, Amide groups or isocyanate derivatives. These can be heated together react.
- the cross-linking temperature depends on its basic structure from. They are usually between 120 and 220 ° C. Powder coatings with Crosslinking temperatures above 180 ° C are preferably only low Amounts added to even at the curing temperature of the molded parts about 160 ° C a complete crosslinking of the binder mixture used to reach.
- the coating powder / cross-linking temperatures are below 160 ° C.
- the epoxy powder coating materials which can be used according to the invention contain epoxy resins as the main binder component. These frequently crosslink via hydroxyl groups in particular hardener containing amide or amine groups.
- Polyester powder coatings are used, in which the main binder component are polyesters containing carboxyl groups.
- existing crosslinkers are, for example, crosslinkers containing epoxy groups or crosslinkers containing amino or amide groups are known. It is it is common for the crosslinkers to be more functional than those Main binder component. If epoxy / polyester mixed powder is used, So-called hybrid systems are approximately the same proportions of polyesters or epoxy resins.
- Polyurethane powder coatings are based on hydroxyl-containing polyesters, the reversibly blocked polyisocyanates, e.g. with known Capping agents such as caprolactam or ketoxime are protected, crosslink can or which are present as urethdione.
- Powder coatings of the acrylate type are generally mixtures of two or more acrylic resins, each functional groups such as epoxy groups, Contain carboxyl groups, hydroxyl groups or isocyanate groups. Here are the mutually reactive groups on different molecules distributed.
- binder powders are e.g. in S.T. Harris, "The Technology of Powder Coatings”, 1976 or in D.A. Bate," The Science of Powder Coatings “ Vol I, 1990.
- Colorless or pigmented powder coatings can be used where as pigments the usual known inorganic or organic Color pigments are possible. It is also possible that effect pigments e.g. Metallic pigments are incorporated into the powder. A Color separation is not necessary. The grain size of the powder is not essential, only care should be taken that the preparation of the binder mixture is generally an average sample of the various powder residues is used. Leading for better mixing behavior and more constant production the binder mixture.
- the powder coatings can be used individually. In order to achieve a composition of the binder mixture a) which is as constant as possible, it is preferred that a mixture of epoxy powders and polyester powder is present as a 2 ). Up to 60% by weight of a 2 ), preferably up to 30%, can optionally be replaced by polyurethane powder and / or polyacrylate powder. It is possible to directly produce a mixture a 2 ) within the desired weight ratios and to store it. Another possible way of working is that the various powder coating components are stored separately according to the chemical types described above and are only mixed with the phenolic resins before further processing. Within these chemical types, the resulting materials are mixed homogeneously, ie a sample is mixed with the composition and pigmentation in grain size distribution. The quantities required in each case are then mixed together from the mixtures of the resulting powder coating binders in the preparation of the binder powders a). If necessary, it is possible to introduce further additional crosslinkers into the binder mixture.
- the powder coating waste which can be used according to the invention is in the form of ground waste Powder before. It may be necessary to use proportions of the binder which are in a coarser form beforehand to a suitable grain size to grind. This can be specified in the for the phenolic resins Order of magnitude.
- customary additives or additives can be added together with the powders.
- These can be, for example, catalysts, accelerators or flame retardants.
- catalysts tin compounds are preferably used as dibutyltin dilaurate, carboxylic acid salts such as lithium benzoate, quaternary ammonium compounds such as tetrabutylammonium bromide, cetyltrimethylammonium bromide, benzyltrimethylammonium chloride, benzyltriethylammonium chloride or tetramethylammonium chloride or tertiary amines such as triisopropylamine or methylimidazole.
- Suitable accelerators and crosslinkers are, for example, basic compounds containing epoxy groups, such as triglycidyl isocyanurates, glycolurils, dicyandiamide or beta-hydroxylamides. These additives can be added individually as powdery substances. They can also be introduced as a masterbatch mixed with binder proportions or they are metered in as a mixture with the binder powder a 1 ).
- Flame retardant substances can also be introduced. These are the usual known substances that are contained in fire protection coatings. Examples of such compounds are borates such as sodium borate; Phosphates such as ammonium phosphate or sodium phosphate; Aluminum hydroxides or oxides; other suitable compounds are, for example, heavy metal-containing compounds such as tin oxide compounds or perbrominated or perchlorinated compounds such as tetrabromophenol. However, heavy metal-free and halogen-free flame retardant substances should preferably be used. These flame retardant substances are available as a powder. They can be introduced via a separate masterbatch or they are metered in via the binder powders a 1 ) or a 2 ) in each case as a homogeneous mixture with the powder component.
- Pigments can also be introduced into the binder mixture a). In general, however, it is preferred not to introduce any additional pigments, but only to use the fibrous fillers of the nonwoven or the pigments contained in the powder coatings a 2 ).
- Another object of the present invention are molded parts that by molding and partially or completely hardening those described above Mixture of fibers and binders can be made.
- the mixtures of fibers and binders are only partial hardened, the so-called prepregs are obtained, which are then in one further processing step by heating to its final shape brought and can be fully cured. Shall the mixture fully cured, so they are in a conventional manner molded into the appropriate shape and for those for each Binder mixture cured suitable crosslinking temperatures.
- Contain the prepreg formed before curing or the finished molded part generally 55 to 80 wt .-% fibers and 20 to 45 wt .-% of Binder mixture.
- the binder mixture consists from 45 to 70% by weight of phenolic resins and 30 to 55% by weight of powder coating binder.
- the additives and additives described above can be in one Amount up to 20% by weight, preferably up to 15% by weight, the sum of the individual components being 100% by weight. Only one type of powder coating can be used or a mixture of several can be used, is preferred however a mixture of polyester and epoxy resins. It is still preferred that the ratio of polyester powder to epoxy powder be 0.2: 1 to 7: 1, preferably 0.8: 1 to 3: 1. It should be when choosing the powder coating waste, however, be careful that this one possess a sufficient number of reactive groups.
- the binder mixtures are used to produce the moldings according to the invention homogenized and together with any additives the nonwoven applied. This is done using known methods.
- the Binder mixture is evenly distributed on the nonwoven and a heating step can then optionally be carried out. As a result, the binder particles soften on the surface and bond firmly to the nonwoven. It arises So-called prepregs, the storage-stable, still deformable web-shaped Nonwovens result. Care should be taken to ensure that it is not yet complete Crosslinking occurs, but the binders continue to heat up can be deformed and flow and network.
- the binder mixture a), the prepregs and also the hardened moldings have a reduced proportion of free phenols or formaldehyde. This reduces the risk posed by these harmful substances.
- the molded parts according to the invention can then be produced from the prepregs obtained in this way. This is done according to known methods such as shaping and / or laminating, making up the prepregs. After the prepregs have been brought into a suitable shape, they are crosslinked by applying pressure and heat. Crosslinking takes place at temperatures from 140 to 200 ° C. The time can be between 10 to 500 seconds, preferably less than 120 seconds. It is chosen depending on the phenolic resin a 1 ) used.
- the binder powder melts and flows, whereby the fibers are at least partially embedded and the resins are chemically crosslinked. This creates a hardened thermoset material.
- the moldings may contain parts of voids.
- the density of the molded parts can be between 50 to 1000 kg / m 3 . It depends on the amount and type of fibers and binders.
- the resulting molded parts have various advantages, such as good heat insulation, dimensional stability up to 130 ° C, good sound insulation, good flexural strength, are physiologically harmless and have a moisture-regulating effect, can be easily processed.
- molded parts can still be coated or they serve as a carrier for other components. This can happen, for example, that together with the cross-linking and shaping of the molded parts, a film on the Surface of the molded part is applied. This is due to the chemical Reaction firmly bound to the surface. It is still possible through the subsequent lamination and laminating of foils a special one To achieve surface coating. Laminating process of molded parts are widely used in industry. You can go after the state of the art.
- the molded parts coated in this way are attractive decorative effect. Depending on the selection of the method, smooth, soft, grained or chemical resistant coated surfaces be preserved. Through the additional use of flame retardant Additives can also be obtained molded parts that are fire-resistant are resistant.
- the molded parts obtained in this way can be used in various industrial areas be used. In particular, they can be found in the automotive industry be used, e.g. as interior trim parts for automotive interiors or sound and heat protection parts. Furthermore, the binder mixtures can be used as resins in linings for clutches. These resins can also be used for mold making in the foundry industry become.
- the resulting molded parts are characterized by a large one Stability and can be shaped in a variety of ways. Through the addition of various additives or through the surface coating it is possible to use them in different fields of application to use.
- the mixture can be used over a longer period of time without further loss of reactivity be stored.
- the mixture has a long shelf life.
- Filter dusts from production are used as polyester powder or epoxy powder the powder coatings used. These are homogenized and then an average sample of these proportions is used in the examples.
- the nonwovens are made by mechanical Movement homogeneously mixed with the binder powder and through a heat channel (approx. 2 - 3 min., 80 ° C - 100 ° C). This creates storage-stable prepregs, in which resin and fiber are combined have connected.
- the prepregs can be made differently according to size and resin / fiber content.
- the bulk density is between 25 and 75 kg / m 3 depending on the application.
- Molded parts are produced from these prepregs.
- the prepregs cut, brought into the intended form in a press and there 100 seconds to 110 seconds at temperatures between 140 ° C and 160 ° C cured. After hardening, thermosetting in heat-stable products.
- the density can vary over the amount of prepreg or influenced by the set pressure.
- the emerging cross-linked molded parts can be flocked in a known manner or they are laminated with foils.
- the molded parts thus obtained have an optically homogeneous surface on, they are dimensionally stable and have only a low content of free Phenol or formaldehyde.
