Definitions
- the coating materials are partly generated as waste.
- the waste arises from the fact that the different application processes have efficiencies ⁇ 1.
- a first type of separator used for this purpose is the so-called dry separator, in which the paint overspray is used with suitable devices, e.g. Filter mats from which exhaust air is separated.
- suitable devices e.g. Filter mats from which exhaust air is separated.
- the resulting waste then consists, for example, of filter mats that are contaminated with polymerized or unpolymerized paint.
- Dry separator systems of this type are preferably used at low overspray rates in large paint shops, for example in auto repair workshops, in bus and aircraft painting, in the furniture and wood industry or in mechanical engineering.
- paint mist can also be removed from the exhaust air with the help of so-called wet scrubbers.
- the air-paint mixture in the scrubber is homogenized with water to which detackifying or coagulating agents have been added. Then there is a mechanical separation of air and water / solids. Since the water is circulated, the resulting waste in most cases consists of a water / paint / auxiliary mixture.
- Paint systems with water separation are used primarily in the automotive industry, the supply industry, the wood and furniture industry, mechanical engineering, engine and transmission construction, shelf construction, in motorcycle and bicycle manufacture etc.
- the water-paint / auxiliary mixture mentioned is relatively pure. This is due to the fact that very often more than one type of paint and more than one color are processed within a painting system. This creates a lacquer coagulate mixture consisting of water, various types of binders and pigments, as well as additional coagulation products and other auxiliaries, e.g. Defoamer, generated.
- EP-A 488 449 describes, inter alia, a process in which alumina is used as a coagulating agent. This creates large amounts of paint coagulate with a high water content (> 50%). With the help of organic coagulants, e.g. Wax dispersions, such as those described in DE-PS 27 58 873, can be used to produce paint coagulates with a low coagulant and water content (approx. 20%).
- organic coagulants e.g. Wax dispersions, such as those described in DE-PS 27 58 873
- Reactive two-component lacquer systems e.g. polyurethane lacquers, polyol / isocyanate systems, two-component epoxy systems, etc.
- drying both at room temperature and at a higher temperature cannot currently be recovered from the lacquer coagulate, especially if they are not collected by type.
- Lacquer coagulates from such systems are currently being deposited or incinerated, at most thermally.
- the invention thus relates to the use of paint waste, paint coagulate or solids loaded with paint waste from painting plants as a component for the production of fired clay materials with improved thermal insulation and / or improved mechanical properties in a quantity of 0.1 to 30 % By weight, based on the non-fired clay material mixture.
- lacquer wastes, lacquer coagulates or solids to which lacquer waste is to be used according to the invention can be based on all lacquers as initially mentioned in connection with the prior art. They encompass all common types of paint that are currently used in painting systems. Lacquers of this type contain reactive, multi-component lacquers and also oven-drying and one-component lacquers drying at normal temperature.
- the reactive, multicomponent paints are, in particular, reactive, two-component paint systems, such as. B. polyurethane varnishes, polyol / isocyanate systems, two-component epoxy systems, etc.
- lacquer waste can also be the basis for the lacquer waste, lacquer coagulate or solids loaded with lacquer waste to be used according to the invention.
- lacquer coagulates can for example, consist of approximately 80% two-component paint and approximately 20% one-component paint.
- the lacquer waste product used according to the invention can be obtained by a wet process as well as by a dry process. These methods were initially described in connection with the prior art.
- Coagulants which can be used in the wet process are, in particular, inorganic products, such as, for example, B. CaCl ", A1 (0H) _, layered silicates, etc., or organic products, such as. B. wax dispersions and organic polymers.
- Suitable coagulants are well known to those skilled in the art.
- An alternative coagulum can also be obtained via an electrostatic process, such as. B. in a coagulating tube gene.
- a wet type entstammendes a paint coagulate which is brought by mechanical dewatering to a solids content of 20 to 95 wt .-%, preferably 60 to 80 wt .-% /.
- a solids content of 20 to 95 wt .-% preferably 60 to 80 wt .-% /.
- an increase in the solids content of the lacquer coagulum obtained by the wet process is also possible with the aid of thermal drying, in which solids contents of up to 100% by weight can be achieved.
- the solids obtained by dry separation and coated with paint waste are comminuted before being used according to the invention.
- the filter mats themselves are not disruptive for the use according to the invention, given appropriate consideration in the manufacturing recipe.
- the amount of waste products to be used according to the invention is in a range from 0.1 to 30% by weight, based on the non-fired clay material mixture.
- the amount to be used in each individual case depends on factors such as the solids content of the paint waste product and can be determined by the person skilled in the art without difficulty.
- Preferred application ranges are in the range from 0.1 to 20, in particular 1 to 10 and especially 1 to 5% by weight, based on the non-fired clay material mixture.
- the paint waste product is incorporated into a customary starting material mixture under suitable mixing conditions in the stated amounts, and the mixture - as far as shaped end products are to be produced - is shaped and fired by customary processes.
- composition of the clay material itself is not subject to any special restrictions and contains the components customary for fired clay materials. So kön ⁇ nen be included next to the sound and the invention • to use paint waste product even sand or silicates, Celluloseabcorpie, Holz ⁇ flour etc. Other components are covered for such Mix ⁇ gen customary additives, including for example, glass fibers and sludges from paper ⁇ processing, or adjuvants which influence the sintering process, for example, alkaline earth metal carbonates.
- the fired clay materials resulting from the use according to the invention can be all common products which are produced from such materials. In particular, however, it is brick building materials such. B. bricks, roof tiles and the like. Clay granules (expanded clay) as well as shaped objects such as vases and pots also fall under the products which can be achieved by the use according to the invention.
- the invention thus also relates to a fired clay material which originates from the present use.
- lacquer coagulate When mixing a clay mixture into which substances such as glass fibers, quartz etc. are added in order to achieve certain brick properties, lacquer coagulate is used in an amount of 0.1 to 30% by weight, preferably 0.1 to 10% by weight and in particular dere 1 to 5 wt .-% added. From this mixture z. B. shaped brick and fired by conventional methods. The bricks obtained have a 10 to 50% better thermal insulation behavior (K value) and a 10 to 30% better flexural strength compared to conventional bricks from a standard production.
- K value thermal insulation behavior
- lacquer coagulate from wet-depositing coating systems coagulated with a wax dispersion (e.g. Divinol Koag 486), are mixed homogeneously into a clay / quartz standard mixture and perforated bricks are formed therefrom (length 240 mm, width 115 mm, Height 113 mm).
- a wax dispersion e.g. Divinol Koag 486
- lacquer coagulates which were produced with a high proportion (> 5%, based on the dry substance of the lacquer coagulate) of coagulants containing alumina, brittle bricks result.
