Abstract
Description
本発明は、含浸または半造膜タイプの木材保護剤に、可視光領域に極大吸収波長を有する色素が添加された木材保護剤、当該木材保護剤が木材に塗装されてなる保護木材、およびその保護木材が備えられた構造物に関する。 The present invention, a wood protective agent impregnated or semi-film forming type, a wood protective agent to which a pigment having a maximum absorption wavelength in the visible light region is added, a protective wood material obtained by coating the wood with the wood protective agent, and It relates to a structure provided with protective timber.
木材は、土木建築用途や一般工業用途など種々の用途に用いられているが、木材は腐朽、カビ、害虫、日光による焼けなどによって劣化する。特に、住宅、建物などの屋外建築物に使用された木材、および公園等のベンチなど屋外で使用される木材は屋外曝露に伴う劣化が激しいので、木材を保護することを目的として、木材を木材保存剤で処理することが行なわれている。 Wood is used for various purposes such as civil engineering and construction and general industrial use, but it deteriorates due to decay, mold, pests, sunburn, and the like. In particular, wood used for outdoor buildings such as houses and buildings, and wood used outdoors such as benches in parks, etc. are severely deteriorated due to outdoor exposure, so wood is used for the purpose of protecting wood. Treatment with preservatives is practiced.
木材保護剤としては、木材の内部に有効成分が浸透して効果を内から発揮する「含浸タイプ木材保護剤」、保護剤の膜で木材表面を覆って木材を守る「造膜タイプ木材保護剤」およびその中間タイプである「半造膜タイプ木材保護剤」が知られている。 As a wood protective agent, an "impregnated type wood protective agent" in which the active ingredient penetrates into the wood to exert its effect from the inside, and a "film forming type wood protective agent" that protects the wood by covering the surface of the wood with a protective agent film ] And its intermediate type, "semi-film forming type wood protecting agent" is known.
造膜タイプ木材保護剤は、表面に膜を作ることで紫外線や雨、菌や害虫などの外敵から木材を守り、長期に渡り保護効果を発揮しようとするものである。造膜タイプの木材保護剤の場合には、木材表面に膜を作るため、木目は見えなくなり、木材の自然な風合いや質感を喪失するだけでなく、経時劣化により、塗膜剥離、亀裂発生等が発生して外観を損なうという問題があった。さらに塗膜が劣化した後に保護用組成物を再塗布する際に、劣化した塗膜の除去に手間がかかるという問題があった。 The film-forming type wood protective agent is intended to protect the wood from external enemies such as ultraviolet rays, rain, fungi and harmful insects by forming a film on the surface, and to exert a protective effect for a long time. In the case of a film-forming type wood protectant, a film is formed on the surface of the wood, so that the grain of wood is not visible and the natural texture and texture of the wood are lost. However, there is a problem that the appearance is deteriorated and the appearance is deteriorated. Furthermore, when the protective composition is reapplied after the coating film has deteriorated, there is a problem that it takes time to remove the deteriorated coating film.
一方、含浸タイプおよび半造膜タイプの木材保護剤は、保護成分が木材内部に浸透し、内から効果を発揮しようとするもので、塗装後も木目が見え、木の風合いを失わないので、木材本来の美しさや手触りをそのまま楽しむことができる。ところが、含浸タイプおよび半造膜タイプの木材保護剤は、特に屋外使用の木材に使用された場合、屋外曝露に伴う劣化が激しいので、含浸タイプおよび半造膜タイプの木材保護剤を再塗装しても、新しい木材のような明るさは回復せず木材の木目や自然な風合いを維持することは難しかった。 On the other hand, impregnating type and semi-film forming type wood protectants have protective ingredients that penetrate into the interior of the wood and try to exert their effect from the inside, so the grain of wood can be seen even after painting and the texture of the wood is not lost. You can enjoy the original beauty and feel of wood. However, the impregnated type and semi-film forming type wood protectors, especially when used for outdoor use wood, deteriorates significantly with outdoor exposure. However, it was difficult to maintain the wood grain and the natural texture without recovering the brightness of new wood.
このような状況の中、特許文献１の下塗り剤の提案により、木材保護剤を塗布する前に下塗り剤を塗装したり、木材保護剤を再塗布する前に下塗り剤を塗装したりすると、屋外曝露劣化を防止して新しい木材の明るさを維持しつつ劣化木材表面の明るさをもある程度回復することが可能となり、木材の木目や自然な風合いをより長期間維持することが可能となった。 Under such circumstances, according to the proposal of the undercoating agent of Patent Document 1, if the undercoating agent is applied before the wood protective agent is applied or the undercoating agent is applied before the wood protective agent is reapplied, It is possible to prevent exposure deterioration and restore the brightness of new wood to some extent while maintaining the brightness of new wood, which makes it possible to maintain the wood grain and natural texture for a longer period of time. ..
しかしながら特許文献１においては、木材の色合い（含模様）、肌触り、および香り等の風合について維持および回復させる提案はなされているが、風合いをより強調させる提案には至っておらず、改良の余地があった。 However, in Patent Document 1, although there is a proposal to maintain and restore the texture (including patterns) of wood, texture, and texture such as scent, there is no proposal to further emphasize texture, and there is room for improvement. was there.
特に特徴的な木材、例えば南三陸に育つ美人杉（芯材がピンク色で外周部が白色を呈する希少な杉）などについては、肌触りおよび香りを維持しながら色合いを際立たせる木材保護剤の開発が強く望まれていた。
本発明は、木材の肌触りおよび香りを維持しながら色合いを際立たせる木材保護剤を提供することを目的とする。

Three years have passed since the non-lot TM clean (clear type) impregnating type wood protectant (Mitsui Chemicals) was applied, the wooden outer wall of a wooden building was washed under high pressure, dried, and brushed. The undercoating agent 5 obtained above was applied and dried again.
乾燥した木製外壁表面を紙やすり＃４００で研磨し、ウエスで表面を清掃した後、上記木材保護剤５を刷毛で木目に沿って、全体に薄い膜ができるまで塗装し（１回目の塗装）、１５分間放置して乾燥させた。塗布表面に残った木材保護剤５をウエスでふき取り、手で触ってべたつかなくなるまで１時間放置して乾燥させた。再び木材保護剤５を薄く塗布し（１回目の塗装と比べて１／３〜１／４程度の量）、木材保護剤５が乾かないうちに、塗布面を紙やすり＃４００を使って、研いだ粉を擦りこむようにして木目に沿って研磨した。表面に残った木材保護剤５を再びペーパータオルでふき取り１４時間放置して乾燥させた。乾燥後、処理した木造建物の木製外壁の表面の外観を目視によって観察した。観察結果を表２に示す。 The surface of the dried wooden outer wall is sanded with sandpaper #400, the surface is cleaned with a waste cloth, and the wood protective agent 5 is applied with a brush along the wood grain until a thin film is formed on the whole surface (first coating). It was left for 15 minutes to dry. The wood protective agent 5 remaining on the coated surface was wiped off with a waste cloth and left to dry for 1 hour until it was not tacky to the touch. Apply a thin layer of wood protectant 5 again (about 1/3 to 1/4 the amount of the first coating), and before the wood protectant 5 dries, use sandpaper #400 on the coated surface. It was rubbed with the sharpened powder and polished along the grain. The wood protective agent 5 remaining on the surface was wiped again with a paper towel and left to dry for 14 hours. After drying, the appearance of the surface of the wooden outer wall of the treated wooden building was visually observed. The observation results are shown in Table 2.
