摘要:
The invention relates to the use of an aminocarboxylic acid or aminocarboxylate in the preservation of wood against attack from insects, particularly from termites of the Coptotermes family or the house longhorn (Hylotrypes bajulus).

The present invention is related to a method of preserving plywood, particle board and similar wood composite products made from wood pieces/particles and a binder used to adhere such wood pieces/particles together against rot and mould decay. According to the invention, the preservative of the wood material is a complexing agent which is capable of binding transition group metals and is admixed into the binder used in the manufacture of said wood composite products prior to the formation of said product. The invention also concerns a binder composition, which contains a polymer resin as its adhesive component and a complexing agent, particularly an aminotetracarboxylic acid or a salt thereof, by approx. 1-30 wt.-% as the preservative of the wood material, and a method of producing said binder composition. Tests performed on faced plywood indicated that a water-soluble, environmentally safe complexing agent offers a white rot resistance which is superior to conventional preservatives commonly used today.

摘要:
The invention relates to a surface treatment composition, which contains a solvent, a binder and a substance which prevents the growth and spreading of microorganisms, a process for preparing such a composition and a method for protecting lumber against undesirable reactions caused by mould, blue-stain fungi and decay fungi and similar microorganisms. According to the present invention the substance which prevents the growth and spreading of microorganisms at least essentially is formed by a complexing agent capable of binding transition metals. Preferably the complexing agent is an inorganic phosphate compound, an aminopolycarboxylic acid or a salt thereof, a hydroxy acid or a salt thereof or an organophosphate or a salt thereof or a metal-binding protein (siderophore). By using complexing agents as the main fungicidal components of paints it because possible to protect both the painted surface and the paint surface from moulding and blue-staining by means of a harmless, inexpensive substance.
