Definitions
- the present invention relates to a composite panel which contains or consists of at least one bioba-based particulate or rod-shaped natural material (excluding wood), at least one thermosetting resin as a binder and at least one inorganic flame retardant.
- the present invention relates to a method for producing a corresponding composite panel.
- the present invention also indicates possible uses of the composite panel according to the invention.
- Effective insulation materials for buildings are an essential part of modern construction to save energy when heating or cooling buildings in order to create a pleasant indoor climate in all climates and in all seasons.
- the building is insulated, for example, by attaching panels with low thermal conductivity to the walls, roofs or floors of buildings.
- the Insulation materials can either be attached to the outside or inside.
- thermal insulation Another possibility for thermal insulation is to fill flea rooms with mats or bulk material with low thermal conductivity.
- Mineral, petroleum-based or renewable raw materials are used as materials with low thermal conductivity for building insulation.
- the mineral insulation materials include, for example, glass or rock wool, the production of which is energy-intensive.
- Insulation materials made from fossil raw materials are mainly foamed plastics such as polystyrene (PS) in the form of panels made of particle foam (EPS) or extruded foam (XPS), which are of great importance on the insulation material market.
- PS polystyrene
- EPS particle foam
- XPS extruded foam
- Other foams used for this purpose are based on polyurethane, phenol-formaldehyde resin or polyethylene. The has a large market share among insulation materials
- EPS Polystyrene particle foam
- Polystyrene foam sheets consist of more than 95% air and still offer good stability with low density, ideal insulation properties and at the same time a low price. Another advantage of polystyrene foam panels is their ease of use, ease of integration into buildings and usability in composite thermal insulation systems.
- a decisive criterion when evaluating a material that is to be used as an insulating material is its fire behavior.
- a classification is carried out by DIN EN 13501-1: 2010. Flammability is required for approval in a wide range of applications.
- Polystyrene foam is per se an easily flammable / combustible material to which a brominated polymer is added as a flame retardant. is set in order to achieve a classification as flame retardant. This ensures the wide use of polystyrene foam as an insulation material.
- Bio-based insulation materials are described in scientific and patent literature and are also used in practice. Bio-based insulation materials are usually available as bulk or blown insulation, but there are certain reservations about settlement phenomena if they are not installed by a specialist company. Insulation panels made from renewable raw materials are also used, but they also have various disadvantages, such as too low pressure loads. Insulation materials made from renewable raw materials are also considered to be normally flammable (building material class E according to DIN EN 13501-1: 2010). It would therefore be advantageous to have insulating materials made from renewable raw materials available that are easy to handle, that is, available as sheet goods, have acceptable mechanical properties and at the same time are flame retardant.
- bio-based base materials are described in the specialist literature for use as insulating material, most of which are side streams from forestry and agriculture. Examples of these are fibers from flax, hemp, jute, sisal, kenaf, miscanthur, grass, banana or coconut and straw from grain, rice, flax, hemp, corn or rapeseed or wood chips, coconut pulp, corn husks, peanut shells, pineapple leaves, sunflower stalks , Reeds, cattails, ba gasse, cotton stalks, bark, pecan shells, durian fruit pods, corn slivers, rice hulls, cork, olive pits or seaweed. Overviews of materials from Renewable raw materials that are suitable as insulating material are provided by C. Aciu and N. Corbirzan in ProEnvironment 6 (2013) 472 - 478, H. Wang, P.-C. Chiang, Y. Cai, C.
- the natural substances described therein are used as insulation in various forms. Loose fibers or particles are introduced into hollow spaces as blown or bulk material. Furthermore, fibers or straw are also stuffed into cavities or frames by hand.
- insulation panels made of natural fiber-based materials are also known commercially. Jute, flax, hemp, wood fibers as well as white grass are generally used to manufacture insulation boards, mats or fleeces without the use of a binding agent. Wood fiber systems that are suitable for use in thermal insulation composite systems (ETICS) are primarily considered to be pressure-resistant. ETICS-compatible materials can also be produced from hemp in a special process (http://www.caparol.de/im- specific / waermedaemmung / capatect-system-natur.html, accessed on March 27, 2017).
- Pressed reed mats offer another option for a thermal insulation composite system, but are unsuitable for perimeter and core insulation (https://www.daemmen-und-sanieren.de/daemmung/daemmstoffe/scun, accessed on March 27, 2017).
- cork granulate is formed into panels under pressure with the supply of steam at around 350 ° C.
- the natural resin suberin escapes from the cells, causing the Expand cells.
- the emerging resin binds the individual particles.
- the insulation properties of natural cork are optimized by the expansion.
- resin-rich cork is suitable for the manufacture of baking cork, so that the individual particles can be sufficiently connected to one another.
- this is the so-called primary cork, i.e. the cork from the first peeling of the cork oak. Cork from later peeling periods or recycled cork cannot be used for this process.
- Another way of producing panels from renewable raw materials that are suitable as insulating material is to bind particulate natural materials with an adhesive, resin or latex.
- A. Paivaa, S. Pereiraa, A. polea, D. Cruza, H. Varumc and J. Pintoa describe in Energy and Buildings, 45 (2012) 274-279, for example, a board made from corncob meal for building insulation.
- a wood glue not described in detail, is mentioned as a binder.
- J. Khedari, S. Charoenvai, J. Hirunlabh in Building and Environment 38 (2003) 435 - 441 describe further plates, consisting of bio-based residue particles, here durian fruit peel. In this study, the particles are mixed with urea-formaldehyde, phenol-formaldehyde - or isocyanate-based adhesives bound.
- S. Tangjuank describes in Int.
- DE 2457345 A1 discloses a material made of cork surface-coated with sand and cement which is used in connection with a binding agent, e.g. Mortar, plaster of paris or synthetic resin can be processed into a component with low density and good heat and sound insulating properties.
- a binding agent e.g. Mortar, plaster of paris or synthetic resin
- mineral materials such as expanded clay, perlite or calcium silicates are also known from nature as insulation materials. As a rule, they are used as bulk goods. Flat thermal insulation systems are also made from perlite and calcium silicates in particular are used in mineral insulation boards. Fumed silica is currently used as an insulating material in vacuum insulation panels (VIPs). VIPs offer very good insulation te with low structural strengths. However, they are difficult to process, if the vacuum barrier is violated, the insulation performance drops significantly (DE 10 2012 224 201 A1).
- insulation materials made from renewable raw materials are considered combustible (fire protection class E according to DIN EN 13501-1: 2010).
- fire protection class E according to DIN EN 13501-1: 2010.
- cellulose fibers or wood wool boards some of which are classified as flame-retardant, they are all classified as E normally flammable
- EP 2 721 121 B1 describes, for example, waste paper which, with various mixtures of different flame retardants from the group consisting of aluminum hydroxide, ammonium sulfate, sodium sulfate, monoammonium phosphate, diammonium phosphate, triammonium phosphate, ammonium polyphosphate, aluminum sulfate,
- Trisodium phosphate, calcium hydroxide and magnesium hydroxide is added.
- the object of the present invention was therefore to offer a composite panel which does not have the disadvantages indicated above, i.e. meets the requirements for modern, efficient insulation materials with regard to density, thermal conductivity and fire behavior, is self-supporting and is not limited to a class of bio-based raw materials with insulation properties, but can generally be implemented with a wide variety of renewable raw materials and has the potential to be recyclable.
