Abstract
The presently claimed and described technology provides wood preservative compositions comprising a preservative, a wax, and an organic solvent, methods for using such compositions to treat wood, and the treated wood.
Claims29
A creosote-and pentachlorophenol-free wood preservative composition comprising:
- i. a preservative selected from the group consisting of 3-iodo-2-propynyl-butylcarbamate, Tebuconazole, Propiconazole, 5-fluoro-1,3-dimethyl-N-[2-(4-methylpentan-2-yl)phenyl]pyrazole-4-carboxamide, chlorothalonil, copper naphthenate, oligomeric alkylphenol polysulfide, and a 3-isothiazolone compound having formula:
- wherein,
- Y is an unsubstituted or substituted (C1-C18)alkyl group, an unsubstituted or substituted (C2-C18)alkenyl or alkynyl group, an unsubstituted or substituted (C6-C12)cycloalkyl group, an unsubstituted or substituted (C7-C10)aralkyl group, or a substituted (C7-C10)aryl group;
- R and R1 are independently hydrogen, halogen or (C1-C4)alkyl groups;
- or
- R and R2 can be taken together with the C═C double bond of the isothiazolone ring to form an unsubstituted or substituted benzene ring,
- ii. a wax having a melting point between and inclusive of about 75° C. to 100° C.;
- and
- iii. an organic solvent.

A method for treating wood, the method comprising contacting the wood with a wood preservative composition comprising:
- i. a preservative selected from the group consisting of 3-iodo-2-propynyl-butylcarbamate, Tebuconazole, Propiconazole, 5-fluoro-1,3-dimethyl-N-[2-(4-methylpentan-2-yl)phenyl]pyrazole-4-carboxamide, chlorothalonil, copper naphthenate, oligomeric alkylphenol polysulfide, and a 3-isothiazolone compound having formula:
- wherein,
- Y is an unsubstituted or substituted (C1-C18)alkyl group, an unsubstituted or substituted (C2-C18)alkenyl or alkynyl group, an unsubstituted or substituted (C6-C12)cycloalkyl group, an unsubstituted or substituted (C7-C10)aralkyl group, or a substituted (C7-C10)aryl group;
- R and R1 are independently hydrogen, halogen or (C1-C4)alkyl groups;
- or
- R and R1 can be taken together with the C═C double bond of the isothiazolone ring to form an unsubstituted or substituted benzene ring,
- ii. a wax having a melting point between and inclusive of about 75° C. to 100° C.;
- and
- iii. an organic solvent,
- wherein the wood is treated at a temperature above the melting point of the wax.
7 more elements
A treated wood, wherein the wood is impregnated with:
- i. a preservative selected from the group consisting of 3-iodo-2-propynyl-butylcarbamate, Tebuconazole, Propiconazole, 5-fluoro-1,3-dimethyl-N-[2-(4-methylpentan-2-yl)phenyl]pyrazole-4-carboxamide, chlorothalonil, copper naphthenate, oligomeric alkylphenol polysulfide, and a 3-isothiazolone compound having formula:
- wherein,
- Y is an unsubstituted or substituted (C1-C18)alkyl group, an unsubstituted or substituted (C2-C18)alkenyl or alkynyl group, an unsubstituted or substituted (C6-C12)cycloalkyl group, an unsubstituted or substituted (C7-C10)aralkyl group, or a substituted (C7-C10)aryl group;
- R and R1 are independently hydrogen, halogen or (C1-C4)alkyl groups;
- or
- R and R1 can be taken together with the C═C double bond of the isothiazolone ring to form an unsubstituted or substituted benzene ring;
- ii. a wax having a melting point between and inclusive of about 75° C. to 100° C.;
- and
- iii. an optional organic solvent.
