Abstract
An anti-termitic composition comprises at least one 8- hydroxyquinoline metal complex as an active component thereof, preferably dispersed in a synthetic resin composition for example represented by a polyvinyl resin composition as a material thereof and optionally contains additionally 8-hydroxyquinoline. The metal moiety of the complex may be selected from the group consisting of Sn, Ba, Sr, Ca, Mg, and Fe.
Description
SPECIFICATION
Anti-termitic composition.
1. This invention relates to an anti-termitic composition, and more particularly to an anti-termitic composition which has little toxic effect on human system and manifests sufficiently persistent efficacy.
In most areas having a warm climate, wooden structures are susceptible of termitic injuries. In the case of cable buried directiy in soil, not only outer layers of synthetic resin and rubber but also metallic sheaths of aluminum and iron have a possibility of sustaining holes formed by the action of formic acid excreted by termites.
As a measure to protect structures and underground cables against such termitic damages, the practice of applying an antitermitic agent to the surface of structures and incorporating the anti-termitic agent into rubber and synthetic resin used in the outer layers of cables has found widespread acceptance.
Heretofore, organic chlorinated compounds have been predominantly used as anti-termitic agents.
These compounds, however, have a disadvantage that since they persist in their undecomposed form, they are suffered to accumulate in living organisms and deposit on environs of sites of application of such agents to jeopardize the health of workers exposed to the agents and bring about environmental pollution.
Lewis et al, "Hydroxyquinoline and Naphthol Termiticides", published in pages 818-822 of the
October 1 978 issue of the "Entromological Society of America," discloses the results of the test conducted on anti-termitic property of 8-hydroxyquinoline and 1-naphthoi incorporated in soil.
From the results, it is noted that i-hydroxyquinoline showed outstanding anti-termitic property and manifested very little toxic effect. This compound, however, has a disadvantage that it boils at a relatively low temperature of 266.60C (752 mmHg) and is slightly soluble even in water (solubility in water 0.05 at 1 80C and 0.35 at 900C) and, therefore, fails to provide the desired anti-termitic property for a long period.
This invention, therefore, seeks to provide an anti-termitic composition which neither pollutes the environment nor adversely affects the health of workers exposed to the composition.
This invention also seeks to provide an anti-termitic composition which provides a high antitermitic effect for a long time.
According to this invention, we provide an anti-termitic composition containing an 8hydroxyquinoline metal complex as an active component thereof.
The invention will now be further described by way of example with reference to the accompanying drawings, wherein: FIG. 1 is a cross section illustrating an apparatus to be used for testing the effect of the active composition in the anti-termitic composition of the present invention. FIG. 2 is a graph showing the relation between the stability"constant and the anti-termitic effect of 8-hydroxyquinoline metal complex.
FIG. 3 is a cross section illustrating an apparatus to be used for testing the effect of a synthetic resin sheet incorporating the active component of the present invention.
The anti-termitic composition of this invention contains an 8-hydroxyquinoline metal complex as an active component thereof.
Examples of the metal moiety of the 8-hydroxyquinoline metal complex include Sn, Ba, Sr, Ca, Mg,
Fe, Cu, Ni, Zn, Mn, and Co. Among other metals, Sn, Ba, Sr, Ca, Mg, and Fe are particularly suitable for the purpose of this invention.
Although 8-hydroxyquinoline metal complexes generally possess very low dissociation constants in water, they siightly undergo dissociation and assume the following states of equilibrium.
(weherin M stands for a metal ion, 8-HOQ for an 8-hydroxyquinoline, and n for a positive integer; which apply hereinafter).
The equilibrium constants k,, k2, . . . k,, therefore, assume the following values.
[M 0 8HOQ1 k1 = [M} [8-HOQ3
(wherein the brackets [ ] designate the concentration of the compound indicated).
The overall stability constant, K, is expressed as follows.
The anti-termitic effect of the 8-hydroxyquinoline metal complex of the present invention issues preponderantly from the 8-hydroxyquinoline produced in consequence of the dissociation of the 8hydroquinoline metal complex.
The notable persistancy of this anti-termitic effect is mainly ascribable to the very high stability constant of the metal complex.
The anti-termitic composition of this invention, therefore, can be made to manifest a powerful anti-termitic effect evenly through'out the entire length of its life from the time of application by incorporating in the composition a plurality of 8-hydroxyquinoline metal complexes having dissimilar stability constants and further by incorporating therein 8-hydrosyquinoline.
Most 8-hydroxyquinoline metal complexes have very high decomposition temperatures and do not experience any sharp loss of weight at temperatures below 300 C. They have substantially no toxic effect upon human system. When they are to be incorporated in synthetic resin or rubber materials they do not impair the working environment.
An 8-hydroxyquinoline metal complex manifests its anti-termitic effect when it is contained in the material in a concentration of only 0.1% by weight. This effect increases in proportion as the content of this metal complex in the material increases. When the content exceeds 10% by weight, however, the anti-termitic effect is no longer increased appreciably. Particularly when the metal complex is contained in a material of synthetic resin or rubber, such a high content of the metal complex goes to degrading the properties of the carrier. Thus, the upper limit of the metal complex content in the anti-termitic composition is desired to be not more than 1 0% by weight.The range of the content of this metal: complex is desired to be from 0.5 to 5% by weight, preferably from 1 to 4% by weight.
The anti-termitic composition of this invention is generally formed by mixing an 8hydroxyquinoline metal complex, or a mixture of two or more 8-hydroxyquinoline metal complexes, or a mixture of an 8-hydroxyquinoline metal complex with 8-hydroquinoline, and a material of synthetic resin or rubber.
A polyvinyl chloride resin composition and a polyethylene composition are particularly suitable examples of the synthetic resin to be used as the material.
Nylon is no suitable synthetic resin for use as the carrier because it has an anti-termitic property in itself.
In the inclusion of the active component in the synthetic resin as the material, the dispersibility of the active component in the material can be improved by having the active component treated in advance with a coupling agent.
The anti-termitic effect of the composition of this invention is heightened by using the active component having its dispersibility in the carrier improved as described above.
Examples of the coupling agent include silane coupling agents and titanate coupling agents.
Examples of the silane coupling agents include, for example, vinyltriethoxysilane, vinyltrimethoxysilane, vinyltris(methoxyethoxy)silane, vinyltrichlorosila ne, y-chloropropyltrimethoxysilane, y-mercaptopropyltrimethoxysilane, y-glycidoxypropyltri methoxysilane, y-a minopropyltriethoxysilane, N-P-(aminoethyl)-y- aminopropyltrimethoxysilane, y-ureidopropyltriethoxysila ne, y-meth acryloxypropyltrimethoxysilane and the like.
And, examples of the titanate coupling agents include, for example, isopropyltriisostearoyltitanate, isopropylcapryloyltitanate, isopropylidiisostearoylcumylphenyltitanante, isopropyltridodecyl benzenesulfonyltitanate, isopropyltris(dioctylpyrophosphate)titanate, tetrakis(2,2-diatlyloxymethyl- 1- butyl)bis(ditridecylphosphite)titanate, tris(dioctylpyrophosphate)ethylenetita nate and the like.
Besides the above coupling agents, it is effective to use fatty acids such as stearic acid, palmitic acid and others.
The amount of the coupling agent or fatty acids to be advantageously used is in the range of from 2 to 3% by weight based on the combined amount of the active component.
Examples of the form in which the anti-termitic composition of this invention is advantageously used include a paint prepared by dispersing the active component(s) in a suitable binder and a blend prepared by mixing the active component(s) with soil.
Now, the present invention will be described more specifically below with reference to working examples.
