o), and by impregnating and adhering these aqueous solutions to fabrics such as curtains, fusuma paper, etc. by dipping, spraying, etc., even if flames from other sources come into contact with the fabrics or fusuma paper, etc. in the event of a fire, they will not be damaged. It has the effect of limiting the amount of carbonization to carbonization and preventing the generation of flames.

するに止まらず、防腐、防虫効果をも併せ持つことを見
出し、本発明に到達したものである。The present inventor impregnated wood products such as building materials with an aqueous solution of a mixture consisting of ammonium monophosphate, ammonium diphosphate, and borax, which has been used as a fireproofing agent for textiles. The present invention was achieved by discovering that the processed product not only becomes flame retardant, but also has antiseptic and insect repellent effects.
本発明の目的は、難燃性を有するとともに、防腐、防虫
効果を備えた木材加工品およびその製造技術を提供する
ことにある。An object of the present invention is to provide a wood product that is flame retardant, has antiseptic and insect repellent effects, and a technology for manufacturing the same.
本発明は、第一燐酸アンモニウム、第二燐酸アンモニウ
ムおよび硼砂からなる混合物の水溶液を含浸させること
によって得られる難燃性木材加工品である。The present invention is a flame-retardant wood product obtained by impregnation with an aqueous solution of a mixture of monoammonium phosphate, diammonium phosphate and borax.
また、本発明はモリブデン酸アンモニウムおよび硼砂か
らなる混合物の水溶液を含浸させることによって得られ
る難燃性木材加工品である。Furthermore, the present invention is a flame-retardant wood product obtained by impregnating it with an aqueous solution of a mixture consisting of ammonium molybdate and borax.
上記混合物中の各成分の割合は、第一燐酸アンモニウム
７０〜８０重量部、第二燐酸アンモニウム１０〜２０重
量部、硼砂１〜２０重量部の範囲とするのが好ましい。The proportions of each component in the mixture are preferably in the range of 70 to 80 parts by weight of primary ammonium phosphate, 10 to 20 parts by weight of secondary ammonium phosphate, and 1 to 20 parts by weight of borax.
上記二種の燐酸アンモニウム塩を上記した割合で配合す

防止する効果もある。しかし、上記混合物中の硼砂の割
合が１重量部以下では、これらの作用、効果を奏するこ
とが困難となる。By blending the two types of ammonium phosphate salts in the above ratio, the ammonium ions of the former combine with the hydrogen ions of the latter in the aqueous solution, thereby acting to suppress the generation of ammonia odor. On the other hand, when heated, borax has a
It produces molten glassy boric anhydride at °C, which blocks oxygen from the air and only carbonizes directly heated areas. Furthermore, since borax has a bleaching effect, its addition has the effect of preventing yellowing of wood products over time that occurs when ammonium phosphate is used alone. Furthermore, since borax has antiseptic and insect repellent effects, it also has the effect of preventing corrosion of wood products caused by microorganisms and damage from insects such as termites. However, if the proportion of borax in the mixture is less than 1 part by weight, it becomes difficult to achieve these functions and effects.

ましい。モリブデン酸アンモニウムの割合が１０重量部
を超えると、木材を変色させることがある。また、高価
なモリブデン酸アンモニウムの大量の使用は、木材加工
品の製造コストを上昇させる。When a mixture of ammonium molybdate and borax is used instead of the mixture of the above two types of ammonium phosphate salts and borax, the proportion of each component is 1 to 1.
It is preferable to set it as 10 parts by weight and borax in the range of 90 to 99 parts by weight. If the proportion of ammonium molybdate exceeds 10 parts by weight, the wood may become discolored. Also, the use of large amounts of expensive ammonium molybdate increases the cost of manufacturing wood products.
上記混合物を用いて木材加工品の難燃化処理を行うには
、上記混合物を適量の水に溶解して水溶液とし、これを
スプレー等によって木材加工品に噴霧するか、あるいは
上記水溶液中に木材加工品を浸漬して上記混合物を木材

を要する。従って、合板やパーティクルボードのような
板状の木材加工品は、浸漬よりもスプレー噴霧で処理す
るほうが好ましい。また、飽和水溶液に近い高濃度の水
溶液を木材加工品の表面に刷毛塗りする方法もある。To make wood products flame retardant using the above mixture, dissolve the mixture in an appropriate amount of water to make an aqueous solution, and spray this on the wood products, or add the wood to the wood in the aqueous solution. The processed product is soaked to impregnate the wood with the above mixture, and then a drying process is performed to remove moisture in the wood. - In general, processed wood products tend to warp when impregnated with a large amount of water, so care must be taken in soaking time and drying method. Therefore, it is preferable to treat plate-shaped wood products such as plywood and particleboard by spraying rather than by dipping. Another method is to brush a highly concentrated aqueous solution close to a saturated aqueous solution onto the surface of the wood product.

材加工品の内部全体に含浸されていなくとも、表面およ
び表面からある程度の内部まで含浸されていればよい。The above two types of ammonium phosphate salts and borax remain in the wood product after the flame retardant treatment, but the ammonium phosphate salts gradually decompose and ammonium is removed from the wood, so eventually Phosphate ions and borax remain. Further, when ammonium molybdate is used instead of ammonium phosphate salt, molybdate ions and borax remain. The ammonium salt and borax do not need to be impregnated into the entire interior of the wood product as long as it is impregnated on the surface and to some extent from the surface.
上記難燃化処理を施した木材加工品は、火災に際して炎

よび硼砂のみであるため、火災に際して有毒、有害なガ
スが発生する虞れもない。Even if a wood product subjected to the above flame retardant treatment is exposed to flames or high heat in the event of a fire, only that part will be carbonized and no flame will be generated. Furthermore, since only phosphate ions (or molybdate ions) and borax are impregnated into the wood product, there is no risk of toxic or harmful gases being generated in the event of a fire.

されるが、これらに限定されるものではなく、置物、額
縁、装飾品等の各種木材加工品に広く適用することがで
きる。As described above, the wood products of the present invention have flame retardant properties as well as antiseptic and insect repellent effects, so they are especially suitable for building materials such as wall materials, floor materials, ceiling materials, columns, and beams, and furniture materials. Applications are expected, but are not limited to these, and can be widely applied to various wood products such as ornaments, picture frames, and ornaments.
なお、表面に塗装を施す木材加工品に前記難燃化処理を
施す場合は、塗装工程に先立って処理を行う必要がある
。塗膜は水分の吸収を妨げるため、塗装後の難燃化処理
は困難である。本発明の難燃化処理は、木材表面の塗膜
の密着性を低下させたり、塗膜の性能を劣化させたりす
ることはない。In addition, when applying the flame retardant treatment to a wood product whose surface is to be painted, it is necessary to perform the treatment prior to the painting process. Since the paint film prevents moisture absorption, flame retardant treatment after painting is difficult. The flame retardant treatment of the present invention does not reduce the adhesion of the coating film on the wood surface or deteriorate the performance of the coating film.
また、表面に紙、塩化ビニル、つき板などを接着した化
粧合板の場合も、これらを接着する工程に先立って前述
した難燃化処理を行う必要がある。Also, in the case of decorative plywood with paper, vinyl chloride, veneers, etc. adhered to the surface, it is necessary to perform the above-mentioned flame retardant treatment prior to the process of adhering these items.

ある。As described above, the wood product of the present invention impregnated with an aqueous solution of a mixture consisting of monoammonium phosphate, diammonium phosphate, and borax, or an aqueous solution of a mixture consisting of ammonium molybdate and borax, has flame retardancy. It also has antiseptic and insect repellent effects, making it an extremely useful wood product especially when applied to building materials and furniture materials.
