Abstract
A novel paste composition for preserving wood is provided herein. Such paste composition includes, as its active wood preservation ingredients, a mixture of 10 -90% by weight of a water-dispersible,ammonia-free, copper naphthenate, and 90 -10% by weight of a borate compound.
Description
This invention pertains to a method and paste composition for the preservation of wood.
There are many methods and compositions for preserving wood prior to the time the wood is put in use. Preservatives for treating wood in place, including both oil-based and water-based products, are also in the market. The oil-based products generally consist of petroleum oils, pentachlorophenol, and creosote. From the standpoint of toxicity and environmPnt~l pollution they are less than desirable.Furthermore, they provide only limited penetration into wood that is wet enough to support decay. The water-based products available often fail to provide adequatesurface protection and are themselves composed of hazardous chemicals.
An object of a main aspect of this invention is to provide a solution to the above deficiencies.

4a 2004637 application of the compositions of aspects of the present invention thereto will add extra years to the life of the pole. Those poles which were poorly pretreated with ..
inferior preservatives, may be again treated while in place. Poles which are removed from one location for setting in another location, usually at a different depth, can be advantageously treated with the compositions of the present invention.
Poles are most effectively treated with compositions of aspects of the present invention by applying a 1/8" to 1/2" thickness of the paste to the excavated pole at the ground line as well as somewhat above and below the ground line. The treatedarea is then wrapped with an impermeable sheet material, e.g., waxed paper or a synthetic plastic sheet. This impermeable material limits the composition being taken up by the soil and/or being leached from the pole to such an extent that an insufficient amount of preserving effect would be obtained. A ready-made package of the compo-sitions of aspects of the present invention may be produced by depositing a layer of the preservative paste on a synthetic plastic sheet or on waxed paper.
Examples To illustrate a suitable composition according to one embodiment of this invention the following ingredients were combined:
Material Weight Percent CUNAPSOL-5TM (the trade-mark for a 5% 40.0 metallic copper equivalent water-dispersible copper naphthenate) Borax (Na2B4O7 - 10 H2O) Clay (ATTAGELrM) 10.0 Water 10.0 This formulation paste was brushed to a 1/4" thickness on 22" wide waxed paper. The coated paper was then wrapped around the ends of ten green pole stubsand ten dry poles stubs so there was 1/4" of the paste adjacent the surface of the wood. These poles stubs were of southern yellow pine and free from decay or previous preservation treatment. They were approximately six fee long and 10" to 12" in diameter. The paper with the 1/4" layer of preservative paste was applied to each stub in such a manner that six inches of the treated paper and stub would be 5 above the ground line and sixteen inches below the ground line. These stubs were placed in the ground with two feet of each stub below ground and four feet above ground. In the same manner ten untreated stubs and ten treated with an oil-based pentachlorophenol preservative paste, known by the trade-mark POL NUTM, were installed for co-llpa,~ e purposes.
10After four years these stubs were thoroughly inspected and two each of the treated stubs were cut into quarters in order to verify penetration and effectiveness of treated chemicals. All of the untreated stubs had been destroyed by decay and/or insect attack. All treated stubs were in excellent condition at the ground line. Stubs treated with the composition of this invention were, to the top free of decay and 15insect attack. Borax was present throughout the stubs, treated green. The tops of the POL NUTM treated stubs were attacked by decay and insects. The pentachlorophenol had migrated approximately half way up the stubs.
Another composition which was prepared in accordance with my invention included the following ingredients:
