[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood preservative / anticidal agent used to protect wood used in building materials from deterioration such as decay and insect damage.

[0002]

2. Description of the Related Art Wood used for building materials and the like is subjected to pressure impregnation with a preservative and insect repellent agent in order to prevent deterioration caused by termites, bark beetles, etc., and rot caused by awatake mushrooms, squash mushrooms, etc. . As such wood preservatives and insecticides, chromium, copper, and arsenic-based chemicals have been widely used, but they have high preservative and insecticidal effects but have hygienic problems.

[0003] On the other hand, studies have been made to substitute a drug which is preferable from a hygiene point of view. For example, a water-soluble copper compound such as copper sulfate alone, an aqueous ammonia solution of a copper compound, or a water-soluble copper compound and an amine are used. And the like are proposed. However, these chemicals have drawbacks such as insufficient stability, a strong ammonia smell and a poor processing environment, and corrosion of metal materials.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and has good stability, low corrosiveness to metallic materials, low toxicity and high antiseptic and insecticidal effects on wood. To provide an agent.

You. And
In this wood preservative / termitic agent, the content of amine nitrogen is 0.35 or more by weight to the content of copper, and the content of carbonate ion, bicarbonate ion and phosphate ion is the content of copper. It is desirable that the weight ratio is 0.35 or more.

Further, according to the present invention, (a) a water-soluble copper compound (excluding basic copper carbonate), (b) (c) an alkanolamine, and (c) a carbonate ion, a bicarbonate ion and a phosphate ion A compound generating at least one anion selected from the group consisting of sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, phosphoric acid, sodium dihydrogen phosphate, disodium hydrogen phosphate, Trisodium phosphate, ammonium dihydrogen phosphate, diammonium hydrogen phosphate, triammonium phosphate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, tripotassium phosphate, copper carbonate, copper phosphate and basic copper phosphate, and A wood preservative / termitic agent dissolved and contained in an aqueous solvent is provided. And in this wood preservative termite,
The content of amine nitrogen is not less than 0.35 by weight to the content of copper, and the content of carbonate ion, bicarbonate ion and phosphate ion is not more than 0.35 by weight to the content of copper.
It is desirable that the number be 5 or more.

The copper compound, which is one component of the wood preservative / termitic agent of the present invention, is selected from copper salts (excluding basic copper carbonate) and copper oxides. Copper formate, copper acetate, organic acid copper salts such as basic copper acetate, such as copper chloride, copper sulfate, copper nitrate, copper phosphate, and inorganic acid copper salts such as basic copper phosphate, and the like. For example, cupric oxide and the like can be mentioned.

The alkanolamine which is one component of the wood preservative / termitic agent of the present invention includes monoethanolamine, diethanolamine, triethanolamine and the like. Further, as the alkyldiamine, ethylenediamine, 1,2-propanediamine , 1,3-propanediamine, N, N-dimethylethylenediamine, N, N
-Diethylethylenediamine and the like.

Further, the compound that generates at least one anion selected from the group consisting of carbonate ion, bicarbonate ion and phosphate ion, which is one component of the wood preservative / termitic agent of the present invention, is sodium carbonate, potassium carbonate, heavy metal, Sodium carbonate, potassium bicarbonate, phosphoric acid, sodium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, ammonium dihydrogen phosphate, diammonium hydrogen phosphate, triammonium phosphate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, tripotassium phosphate , Copper carbonate, copper phosphate and basic copper phosphate.

In producing the wood preservative / termitic agent of the present invention using each of these components, a copper compound is first dissolved or dispersed in water, and then an alkanolamine and an alkyldiamine are added. It becomes completely water soluble.
At this time, if the ratio of the weight of amine nitrogen to the weight of copper is less than 0.35, the stability of the preparation is poor, and there is a practical problem due to the occurrence of precipitation and the precipitation of metallic copper. Alkyl diamines are also effective for solubilizing poorly water-soluble copper compounds.

Therefore, the amount of the alkyldiamine used may be in the range necessary for completely solubilizing the copper compound, and it is not always necessary to use the alkyldiamine as long as the copper compound has good water solubility. When carbonate solution, bicarbonate ion or phosphate ion is absent or small in the aqueous solution obtained by dissolving the copper compound thus obtained and alkanolamine, at least one selected from carbonate ion, bicarbonate ion and phosphate ion Is added and dissolved to obtain the wood preservative / anticidal agent of the present invention. At this time, if the total content of carbonate ion, bicarbonate ion and phosphate ion is less than 0.35 by weight ratio to the copper content, the stability of the preparation is poor, and the generation of precipitates and the precipitation of metallic copper This is not preferable because problems such as these occur.

[0012] The wood preservative / termitic agent of the present invention may contain a defoaming agent, a surfactant, a water repellent and the like for modifying the treatment liquid or the treated wood. Further, it may contain a pesticidal compound such as a boron-based, fluorine-based, organic phosphorus-based or pyrethroid-based compound, a quaternary ammonium salt, and other preservative and termiticides.

[0013]

The wood preservative / anticidal agent of the present invention imparts antiseptic and insect repellent properties by injecting it into wood under pressure. It has good chemical stability and can deteriorate even after repeated injection operations. There is no worry about metal corrosion.

[0014]

EXAMPLES The following various formulations were prepared, and the ratio of the weight of the amine nitrogen contained in the alkyldiamine and the alkanolamine to the weight of copper (abbreviated as the nitrogen ratio) was determined. The calculation results of the ratio of the total content of carbonate ion, bicarbonate ion and phosphate ion to the content weight (abbreviated as ion ratio) are also shown.
