摘要:
A wood preservative, characterized in that it includes (a) 0.5 to 50 parts of a biocidal quaternary ammonium compound or of a mixture of biocidal quaternary ammonium compounds; (b) 0.5 to 50 parts of an aliphatic or cycloaliphatic carboxylic acid having 6 to 30 carbon atoms, or a mixture of such carboxylic acids; (c) 0 to 5 parts of additional biocidal substances; (d) 0 to 20 parts of one or more binders, colorants and/or pigments; (e) 0 to 20 parts of one or more additives for imparting hydrophobicity, moisture regulation and/or drying; and (f) 40 to 99 parts of a nonpolar organic solvent, with the proviso that the ratio between components (a) and (b) is between 1:3 and 3:1.
摘要:
Solvent-free coating materials and treating agents used as water-based wood or material protective agents containing emulsifiable binding agents, quaternary ammonium compounds and optional additional active agents. The wood or material protective agents are non-flammable and enable a uniform distribution of the binding agent and the quaternary ammonium compounds in the substrates. As a result, the quaternary ammonium compounds function as a dissolving mediator for the binding agents which are dispersed in water without opacifying effects and are used as a biocide. The agents can additionally absorb water-insoluble organic biocides without impairing the homogeneity or stability of the formulation of the homogeneity of the distribution in the substrate.
摘要:
Compositions for the protective treatment of wood against rot and attack by insects which comprise at least the following components: a) 10-90 parts of coal-tar oil b) 2-20 parts of a biocidally active quaternary ammonium compound c) 10-90 parts of water. are described. The compositions according to the invention are easily preparable stable emulsions which are distinguished, inter alia, by good penetrability, strongly reduced odour of the treated woods, absence of annoying tar oil enrichments at the surface and strongly reduced “bleeding” of the treated wood at hot temperatures, considerably enhanced activity in spite of a lower coal-tar oil content and reduced toxicity compared to pure coal-tar oil.
摘要:
Heat-foamable fireproofing compositions contain thermosetting phenolic resins, thermally decomposable organic nitrogen compounds, eg. dicyandiamide, an ammonium salt and a carbohydrate or polyhydric alcohol, and on decomposition form a stiff carbonaceous foam.
摘要:
A wood preservative based on a water-dilutable formulation of the compound di-(N-cyclohexyldiazoniumdioxy)-copper, a polyamine, a complex-forming carboxylic acid and, if required, a salt having a fungicidal anion has a pH in the aqueous solution of not less than 7.5 in the conventional concentration for use.
摘要:
An oil-borne wood preservative composition for treating poles, posts, piling, cross ties and other wooden structures. The wood preservative composition comprises a fatty acid, bivalent copper, an organic co-biocide and an oil. Methods of producing the composition and methods of treating wood are disclosed.
摘要:
Wood preservatives which are based on a zinc compound and an aliphatic carboxylic acid and additionally contain a polyamine and processes for preserving wood with these preservatives.
摘要:
A wood preservative based on an aqueous mixture of boric acid and a water-soluble organic amine, which mixture additionally contains sodium polyborate or a mixture of boric acid and borax.
摘要:
Flame resistant foams and other compositions containing polyurethane and/or polyisocyanurate groups are prepared by reacting an organic polyisocyanate with a polyol in the presence of flame retardants, catalysts, blowing agents as well as optionally chain extenders, cross-linkers auxiliaries and additives. The flame retardents comprise a phenol or melamine formaldehyde condensate, pentaerythritol as well as ammonium phosphate and preferably in addition dicyandiamide.
