  • Patent number: 8623423
    Abstract: The present invention relates to boron-containing compositions. The invention relates to comminuted, heterogeneous boron-containing compositions which are obtainable by a process which comprises heating to a temperature sufficiently high that calcination occurs but insufficient for the formation of a homogeneous melt a mixture comprising components capable, under the conditions of heating, of forming the oxides B2O3 and SiO2 and optionally Al2O3, Na2O and/or CaO in proportions such that the relative percentages by weight of the said oxides, based on the total weight of said oxides, are as follows: 5 to 35% B2O3; 10 to 65% SiO2; 0 to 35% Al2O3; and up to 20% Na2O and/or up to 50% CaO; with the proviso that the said B2O3 content is not 10 to 18%, when the other contents are as follows: 40 to 65% SiO2, 17 to 32% Al2O3 4 to 9% Na2O, and 0 to 10% CaO, and then comminuting the resulting composition.

  • Patent number: 8119031
    Abstract: Preservative composition for lignocellulosic-based composites providing rapid and long-lasting protection against insect and fungal attack, in both low and high moisture environments, through the use of a combination of higher solubility and lower solubility borates. Pesticidal amounts of a lower solubility borate and a higher solubility borate are combined before or during their incorporation into a lignocellulosic-based composite. Useful low solubility borates include copper borate, zinc borate and barium metaborate. Useful high solubility borates include boric acid, boric oxide, ammonium borate and alkali metal borates such as sodium borate. Some alkaline earth metal borates, including calcium borates, calcium magnesium borates, magnesium borates and calcium sodium borates, are of intermediate solubility and may be used effectively as either a low soluble or high soluble borate depending on the combination used.

  • Patent number: 7691922
    Abstract: The addition of zinc borate alone or together with a hindered amine light stabilizer and ultra-violet light absorber to organic materials such as thermoplastic polyolefin resin, as is common in wood-plastic composites, provides a substantial reduction in the ultra-violet light degradation of the resin in comparison with similar materials made without zinc borate. This could provide substantial improvements in the long term durability of wood-plastic composites and other organic materials which are used in exterior environments and subject to ultra-violet exposure from the sun.

  • Patent number: 7163974
    Abstract: Lignocellulosic-based woodfiber-plastic composite products containing a pesticidal amount of calcium borate is resistant to attack by wood destroying fungi and insects. The preferred calcium borates are the calcium polytriborates having a CaO:B2O3 molar ratio of about 2:3 and calcium hexaborates, having a CaO:B2O3 ratio of 1:3. Composites can be produced by combining the calcium borate with particles of the lignocellulosic material and the thermoplastic resin binder, and heating and extruding the resultant mixture through a die to form the composite product.
