<p>A novel wood-modifying composition and a method for its preparation, as well as its uses are disclosed. The composition is made mainly from the following starting materials: 37% formaldehyde, borax, aqueous ammonia, urea, melamine, boric acid, cyanoguanidine phosphate, higher alkyl quaternary ammonium salt, sodium dodecyl sulfate, alkylphenol ether sulfosuccinate Na salt, decyl phenol polyoxyethylene ether, N-methylol acrylamide, butyl acrylate, styrene, isooctyl acrylate, acrylic acid, tert-dodecyl mercaptan, ammonium persulfate, sodium hydrogen carbonate, sodium metabisulfite, chlorinated paraffin having chlorine content of 50-60%, an microemulsion of silica which has solids content of 45% and/or an microemulsion of aluminum oxide hydrate which has solids content of 40%. The artificial forest woods and inferior woods modified by the invention composition have excellent flame-retarding, mothproofing, mildewproofing, and preservative properties in addition to the marked improved physical-mechnical properties. Morever, such drawbacks of prior art as that the existent wood preservatives often have heavy metal ions and other toxic components are overcomed.</p> |
