Definitions

  • the present application relates to processes for the production of wood materials from lignocellulose, in particular for the production of chipboard, fiberboard or OSB boards, these wood materials to prevent or reduce the emission of volatile organic compounds and possibly very volatile organic compounds, especially terpenes and acids, be treated with at least one additive during manufacture.
  • these additives are amidines and / or borates.
  • the present application is directed to the use of amidines and / or borates as additives in the production of wood-based materials from lignocellulose for reducing the emission of VOC and optionally VVOC, in particular for reducing the emission of terpenes and acids.
  • the application is directed to obtainable by the process according to the invention wood materials, or by using the additives produced wood materials with reduced emission of volatile organic compounds, in particular terpenes and acids.
  • Lignocellulosic or lignocellulosic materials such as wood and wood pulp products, and derived timber products, such as wood-based panels, contain, among other things, volatile organic compounds (VOCs) and very volatile organic compounds (VVOCs).
  • VOCs volatile organic compounds
  • VVOCs very volatile organic compounds
  • the emission of these VOC and VVOC also referred to as the total amount of volatile compounds
  • volatile organic compounds (VOCs) in addition to saturated and unsaturated aldehydes, include all volatile organic compounds whose retention time in the glass chromatograph is between C 6 (Hexane) and C 16 (hexadecane).
  • VOCs are not a homogeneous class of substances but a smorgasbord of compounds.
  • VVOC very volatile organic compounds
  • these VVOC include organic acids, saturated and unsaturated aldehydes, eg. As pentanal, hexanal, etc., alcohols, terpenes, aliphatic and aromatic hydrocarbons and much more.
  • VVOC very volatile organic compounds
  • formaldehyde or formic acid also occur in the production but also in the use of wood-based materials.
  • these compounds can occur during curing from the adhesives.
  • these compounds can occur by reaction of compounds present in the wood material. The emission of these volatile and highly volatile wood constituents or constituents of the adhesives from wood products, including wood-based panels, is becoming more and more of a problem due to stricter limits or greater sensitization of the end users.
  • the volatile organic compounds and volatile organic compounds are dependent on the type and condition of the lignocelluloses; such as the type of wood, the storage period, the storage conditions of the wood or the crushed products of the wood, in different chemical compositions and quantities.
  • the VOC originate essentially from extractives of lignocelluloses, eg. As the wood or conversion products thereof. Prominent representatives of these are substances such as alpha-pinene, beta-pinene, delta-3-carene. Especially in wood conifers, these components are found again. Conversion products, the z. B. occur during storage and processing of the wood and the crushing products, z. B. aldehydes, such as pentanal and hexanal.
  • Mainly particleboard, medium density fibreboard (MDF) or OSB boards are used to produce large quantities of resins and fats that lead to the formation of volatile organic terpene compounds and aldehydes. Some of these substances are also formed by degradation of the main components of the wood, such as lignin, cellulose and hemicellulose.
  • TVOCs with VOCs including aldehydes as well as VVOCs including formaldehyde can also arise when using certain adhesives for making the wood-based material.
  • VOC emissions are composed of the so-called primary emissions of volatile wood constituents, such as terpenes, or chemical degradation products, such as acetic acid, and so-called secondary or tertiary emissions, as listed above.
  • conversion products eg. B. by fragmentation of the resins and fats
  • a permanent secondary or tertiary emission of said compounds takes place.
  • So z. B. especially in OSB panels in the design field this release of great disadvantage, since in this application, the OSB panels have no emission-reducing coating and installed in large quantities, especially as the area of the plate, based on the total cubic meters of the room or building becomes.

  • the resulting VOC and VVOC, such as aldehydes and acids or terpenes then emit during the manufacturing process or later use of the wood-based materials produced. They can also have a negative influence on the bond strength and thus adversely affect the property of the produced wood materials.
  • VOC volatile organic compound
  • US Pat. VVOC highly volatile organic compounds
  • the emission of VOCs and also of VVOCs should be significantly reduced both during production and during later use become.
  • the additives themselves should not show any toxic properties and should not adversely affect the production process itself.
  • the production costs of wood-based materials themselves must not be significantly increased.
  • the agents or additives used should as far as possible be reacted with the heterogeneous classes of volatile organic compounds as well as the very volatile organic compounds or prevent their formation from constituents of the wood-based materials.
  • additives are added at certain times in the process according to the invention for the production of wood materials from lignocellulose, in particular for the production of chipboard, fiberboard or OSB boards.
  • additives are an amidine and / or borate, aluminate and / or phosphate, in particular borate.
  • the compounds obtained by the reaction are such that they are no longer volatile and thus no longer contribute to the TVOC emissions, or the toxicity of the resulting compounds is significantly reduced. As a result, the emission is also after the production, d. H. in daily use, significantly reduced.

  • Other preferred methods for incorporating the additive I into the lignocellulosic crushing products include methods in which the amidine is added in the form of a solid, such as salt, in the scattering of the lignocellulose-containing comminution products, and preferably the construction of the additive relative to bare wood in the range from 2 to 30% by weight, such as in a range of 5 to 25% by weight, e.g. B. 10 -20 wt .-%.

  • those having an ammonium group are also possible and may contain hydrate groups.
  • the polyborate acts catalytically in the reaction of the amidines or amines with the aldehydes.
  • the borate acts as an antioxidant and thus prevents the oxidative degradation of resins and fats and other wood components that are responsible for the secondary and tertiary emission of terpenes and acids or their degradation products.
  • the borates and polyborates as additives not only prevent the emission of VOC by reacting with or prevent the degradation of VOC, but also form a mechanical barrier to prevent the emission of VOC and VVOC. That is, it is assumed that the borates form an amorphous glassy melt due to the high pressing temperatures, which closes the open surfaces of the wood materials, such as the OSB, and thus also mechanically prevents emission.
  • the borates / polyborates as well as the aluminates and phosphates as additive II allow terpene reduction, presumably due to their property as Lewis acid. These act as catalysts for the addition of the double bond in terpenes. Thus, degradation of the terpenes into volatile organic degradation products that contribute to secondary and tertiary emission is prevented.
