example 1

[0048] This example demonstrates the preparation of a dispersion of a micronized metal compound according to the present invention. Five hundred (500.0) grams of copper hydroxide were added to a container containing 1091.7 grams white mineral spirits and 125.0 grams of dispersants / wetting agents. The mixture was mechanically stirred for 5 minutes and then placed in a grinding mill. The sample was ground for about 30 minutes, and a stable dispersion containing about 30 wt % copper hydroxide was obtained with an average particle size of 0.195 micrometers.

example 2

[0049] This example demonstrates the preparation of a dispersion of a micronized metal compound according to the present invention. One thousand (1000.0) grams of basic copper carbonate was mixed with 2158.3 grams of #2 fuel oil and 175.0 grams of wetting agents / dispersants. The mixture was mechanically stirred for 10 minutes. The mixture was then placed in a grinding mill and ground for about 20 minutes. A stable dispersion was obtained with an average particle size of 0.199 micrometers.

example 3

[0050] This example demonstrates the preparation of a dispersion containing a micronized metal compound and a micronized organic biocide according to the present invention. One thousand (1000.0) grams of basic copper hydroxide and 20 grams of tebuconazole were mixed with 3780 grams of mineral spirits and 200 grams of wetting agents / dispersants. The mixture was mechanically stirred for about 10 minutes. The mixture was then placed in a grinding mill and ground for about 30 minutes. A stable dispersion containing 25 wt % basic copper carbonate and 0.5wt % tebuconazole was obtained with an average particle size of 0.200 micrometers.

Abstract

Provided is a composition for the preservation of wood and other cellulosic materials. The composition comprises a dispersion of micronized inorganic compounds and/or organic biocides in an organic carrier. Also provided is a method for making the composition.

Description

[0001] This application claims priority to U.S. provisional application No. 60 / 618,729, filed on Oct. 14, 2004, the disclosure of which is hereby incorporated by reference.FIELD OF THE INVENTION [0002] The present invention pertains to wood preservation, and more specifically to the use of micronized metals, metal compounds, and organic biocides as wood preservatives. BACKGROUND OF THE INVENTION [0003] Wood preserving compositions are used to protect wood and other cellulose-based materials, such as paper, particleboard, textiles, rope, etc., from attack by wood-destroying organisms, such as, for example, fungi, bacteria and insects. Conventional wood preserving compositions often contain inorganic compounds, organic biocides, or both in an organic carrier. Examples of inorganic compounds used heretofore are compounds of copper, zinc, tin, boron, fluoride, etc. Organic biocides used heretofore include insecticides, fungicides, moldicides, algaecides, bactericides, etc. that have bee...
