Abstract
A liquid wood preservative solution includes sufficient quantities of a copper compound known as having beneficial effects as a wood preservative to provide a copper metal content of between 1% and 6% by weight. At least 6% by weight of a liquid amine solvent is provided for every 1% of the copper metal. The liquid wood preservative solution includes between 10% and 30% by weight of a boron compound known as having beneficial effects as a wood preservative. At least 1% by weight of glycol is provided for every 1% of the boron compound.
Claims6
A liquid wood preservative solution, comprising:
- a homogeneous solution, containing:
- sufficient quantities of a copper compound known as having beneficial effects as a wood preservative to provide a copper metal content of between 1% and 6% by weight;
- at least 6% by weight of liquid amine solvent for every 1% of the copper metal;
- between 10% and 30% by weight of a boron compound known as having beneficial effects as a wood preservative;
- and
- at least 1% by weight of glycol for every 1% of the boron compound, such that the homogeneous solution does not separate into liquid layers with the passage of a period time of at least one year.
A liquid wood preservative solution, comprising:
- a homogeneous solution, containing:
- sufficient quantities of copper naphthanate to provide a copper metal content of between 1% and 6% by weight;
- at least 6% by weight of triethanol amine solvent for every 1% of the copper metal;
- between 10% and 30% by weight of a boron compound known as having beneficial effects as a wood preservative;
- and
- at least 1% by weight of propylene glycol for every 1% of the boron compound, such that the homogeneous solution does not separate into liquid layers with the passage of a period time of at least one year.
A liquid wood preservative solution, comprising:
- a homogeneous solution, containing:
- sufficient quantities of copper naphthanate to provide a copper metal content of between 2% and 3% by weight;
- at least 6% by weight of triethanol amine solvent for every 1% of the copper metal;
- between 15% and 25% by weight of a boron compound containing sodium known as having beneficial effects as a wood preservative;
- and
- at least 1% by weight of propylene glycol for every 1% of the boron compound, such that the homogeneous solution does not separate into liquid layers with the passage of a period time of at least one year.
