本発明に係る耐白蟻成膜剤は、アモルファスシリカとリチウムとのシリケート結合物を主成分とし、木材又は発泡ウレタン材の表面にセラミックス硬化膜を形成するものである。   The termite-resistant film forming agent according to the present invention is mainly composed of a silicate combination of amorphous silica and lithium, and forms a cured ceramic film on the surface of wood or urethane foam.

アモルファスシリカとリチウムとのシリケート結合物としては、無水珪酸（SiO2）と水酸化リチウム（Li2O）とを所定条件下で混合反応させてシリケート結合させたものが好適に用いられる。この場合、塗布性や膜硬度を考慮すると、モル比（SiO2／Li2O）が4.5〜7.5の範囲のものが特に好ましい。 As the silicate bonded product of amorphous silica and lithium, a product obtained by mixing and reacting anhydrous silicic acid (SiO 2 ) and lithium hydroxide (Li 2 O) under a predetermined condition is preferably used. In this case, in consideration of applicability and film hardness, a molar ratio (SiO 2 / Li 2 O) in the range of 4.5 to 7.5 is particularly preferable.

上記耐白蟻成膜剤には、ジョードメチル−ｐ−トリルスルフォンを添加してもよい。この場合、塗布性や膜硬度を考慮すると、重量比で0.5％〜２％の割合で添加したものが特に好ましい。   You may add jodomethyl-p-tolyl sulfone to the said white ant-resistant film-forming agent.

また、上記耐白蟻成膜剤には、パープルオロアルキル化合物を主成分とする界面活性剤を添加してもよい。この場合、塗布性や膜硬度を考慮すると、重量比で0.005％〜0.05％の割合で添加したものが特に好ましい。   Moreover, you may add the surfactant which has a purple oroalkyl compound as a main component to the said white ant-resistant film-forming agent. In this case, in consideration of applicability and film hardness, it is particularly preferable to add 0.005% to 0.05% by weight.

また、上記耐白蟻成膜は、木材又は発泡ウレタン材の表面に刷毛塗りなどによる塗布又は真空加圧注入などによる含浸によりアモルファスシリカとリチウムとのシリケート結合物を主成分とするセラミックス硬化膜を形成することができる。この場合、膜硬度を考慮すると、平米当り50cc以上塗布することが特に好ましい。   In addition, the above-mentioned white ant-resistant film formation forms a cured ceramic film mainly composed of a silicate combination of amorphous silica and lithium on the surface of wood or urethane foam material by application by brushing or impregnation by vacuum pressure injection. can do. In this case, considering the film hardness, it is particularly preferable to apply 50 cc or more per square meter.

さらに、上記耐白蟻成膜は、セラミックス硬化膜の表面に酸化チタンを主成分とする被膜を形成してもよい。   Furthermore, in the above-mentioned white ant resistance film formation, a film mainly composed of titanium oxide may be formed on the surface of the cured ceramic film.

このように、上記耐白蟻成膜は、セラミックス硬化膜の表面に酸化チタンを主成分とする被膜を形成した場合には、膜硬度を向上させるとともに白蟻に対する忌避効果を向上させることができ、耐白蟻効果をより一層向上させることができる。   In this way, the above-mentioned white ant film formation can improve the film hardness and the repelling effect against white ants when a film mainly composed of titanium oxide is formed on the surface of the cured ceramic film. The white ant effect can be further improved.

そして、本発明では、木材又は発泡ウレタン材の表面にアモルファスシリカとリチウムとのシリケート結合物を主成分とするセラミックス硬化膜を形成することができ、木材又は発泡ウレタン材の表面を硬化させることができ、白蟻による食害を未然に防止することができる。   And in this invention, the ceramic cured film which has the silicate coupling | bonding material of an amorphous silica and lithium as a main component can be formed in the surface of a wood or a urethane foam material, and the surface of a wood or an urethane foam material can be hardened. This can prevent damage caused by white ants.

しかも、本発明では、アモルファスシリカとリチウムとのシリケート結合物、ジョードメチル−ｐ−トリルスルフォン、シリカアルミナに酸化銀を担持したコロイド、パープルオロアルキル化合物を主成分とする界面活性剤のいずれにも蒸散作用が無く、人体に害を及ぼすことがなく、木材や発泡ウレタン材の表面に安全性の高い耐白蟻成膜を形成することができる。   Moreover, in the present invention, any of silicate combination of amorphous silica and lithium, jodomethyl-p-tolylsulfone, colloid in which silver oxide is supported on silica alumina, and a surfactant mainly composed of purple oroalkyl compound are used. There is no transpiration, no harm to the human body, and a highly safe white ant-resistant film can be formed on the surface of wood or urethane foam.

以下に、本発明に係る耐白蟻成膜剤によって形成した耐白蟻成膜の実証試験の結果を示す。   Below, the result of the verification test of the white ant film-forming formed with the white ant film-forming agent according to the present invention is shown.

実証試験では、基材として10cm×20cmの杉板を用いた。   In the verification test, a 10 cm × 20 cm cedar board was used as the base material.

また、実証試験では、耐白蟻成膜剤として、無水珪酸と水酸化リチウムをモル比（SiO2／Li2O）が7.5でシリケート結合させてアモルファスシリカとリチウムとのシリケート結合物を生成し、これにジョードメチル−ｐ−トリルスルフォンを主成分とする防カビ剤を重量比で１％の割合で添加し、さらに、シリカアルミナに酸化銀を担持したコロイドを300ppmの割合で添加し、パープルオロアルキル化合物を主成分とする界面活性剤を重量比で0.02％の割合で添加したものを用いた。 In the demonstration test, silicic acid anhydride and lithium hydroxide were silicate-bonded at a molar ratio (SiO 2 / Li 2 O) of 7.5 as a white ant film-forming agent to produce a silicate bond between amorphous silica and lithium, To this, an antifungal agent mainly composed of jodomethyl-p-tolylsulfone was added at a ratio of 1% by weight, and a colloid carrying silver oxide on silica alumina was added at a ratio of 300 ppm. What added the surfactant which has an alkyl compound as a main component in the ratio of 0.02% by weight ratio was used.

また、実証試験では、成膜方法として、基材の表面に刷毛塗りを施して、基材の表面に均等量塗布し、塗布後に常温にて乾燥させてセラミックス硬化膜を形成した。   In the demonstration test, as a film forming method, the surface of the base material was brushed, applied to the surface of the base material in an equal amount, and dried at room temperature after application to form a cured ceramic film.

そして、何ら表面に耐白蟻成膜を形成していない無垢の基材をNo.1試料とし、表面に耐白蟻成膜を平米当り50ccの量を１回の刷毛塗りで施した基材をNo.2試料とし、No.2試料の表面にさらに酸化チタンを主成分とする塗布剤を平米当り50ccの量で塗布し常温乾燥させた基材をNo.3試料とし、表面に耐白蟻成膜を平米当り100ccの量を２回の刷毛塗りで施した基材をNo.4試料とし、No.4試料の表面にさらに酸化チタンを主成分とする塗布剤を平米当り50ccの量で塗布し常温乾燥させた基材をNo.5試料とし、これらNo.1試料〜No.5試料を白蟻の中でも特に強靭なイエシロアリが約20000匹存在する巣の近傍に載置して、１週間放置した。   A solid substrate with no pea-resistant film formed on the surface was used as the No. 1 sample, and a substrate with a white ant film formed on the surface was applied with a single brush application in an amount of 50 cc per square meter. .2 sample, and a base material obtained by applying a coating agent mainly composed of titanium oxide in the amount of 50cc per square meter and drying at room temperature on the surface of No.2 sample, and forming a No.3 sample on the surface. The base material coated with 100cc per square meter with two brushes is used as the No.4 sample, and a coating agent mainly composed of titanium oxide is applied to the surface of the No.4 sample in an amount of 50cc per square meter. The substrate dried at room temperature was used as a No. 5 sample, and these No. 1 to No. 5 samples were placed in the vicinity of a nest where about 20,000 particularly strong termites exist among white ants and left for one week. .

その結果、No.1試料では、重量が半減するまでに激しく食害されたのに対し、No.2試料では、３箇所のピンポイント状の食害箇所が見られ、No.3試料〜No.5試料では、全く食害箇所が見られなかった。   As a result, the No.1 sample was severely damaged until the weight was reduced by half, while the No.2 sample showed three pinpoint-like damaged areas, from No.3 to No.5. In the sample, no damage was found.

なお、No.2試料では、拡大観察の結果、３箇所の食害箇所では基材の表面における凹凸の影響でセラミックス膜の膜厚が十分に確保されていなかったことがわかった。これは、No.4試料の結果から、重ね塗りなどによりセラミックス膜の膜厚を確保することで防止できる。   In the No. 2 sample, as a result of magnification observation, it was found that the film thickness of the ceramic film was not sufficiently ensured due to the unevenness on the surface of the base material at the three places of damage. This can be prevented by securing the film thickness of the ceramic film by overcoating or the like based on the results of the No. 4 sample.

以上の実証試験の結果からも、本発明による耐白蟻効果が実証された。   From the results of the above demonstration tests, the white ant resistance effect according to the present invention was verified.
