技術は公知（特開昭61−244502号公報参照）である。[Prior Art and its Problems] In the state of wood (bar, plate or veneer), a technique of dispersing and fixing an incombustible inorganic compound in the intracellular pores of the wood to make it flame-retardant is known (JP-A-61- No. 244502).
しかしながら、木材（棒，板または単板）の状態に於

よるが、不燃性無機化合物を溶かした溶液中に長時間浸
漬しなければ含浸させることができず、かつ、周辺部に
多く含浸するため内部までの均一な分散は困難であっ
た。However, in the state of wood (rod, plate or veneer), in order to disperse the non-combustible inorganic compound in the wood by 40% by weight or more based on the absolute dry weight of the wood, it depends on the size of the cross-sectional shape. However, it cannot be impregnated unless it is immersed in a solution in which a non-flammable inorganic compound is dissolved for a long time, and a large amount of it is impregnated in the peripheral portion, making it difficult to uniformly disperse it to the inside.
また、不燃性無機化合物を木材の細胞孔内に生成する
ためには、不燃性無機化合物を溶解した第１液に浸漬し

着してなる。Further, in order to generate a non-combustible inorganic compound in the cell pores of wood, the first liquid in which the non-combustible inorganic compound is dissolved is impregnated to a saturated state and then the second liquid is impregnated under the same conditions.

性能が低下し、比較的短い時間で第２液槽を取り換えな
ければならず、さらに、第２液中に反応生成物が沈殿し
てしまうため、その廃棄に困るとともに不経済であっ
た。However, in this method, since the reaction product is generated from the peripheral portion of the wood, it is difficult for the second liquid to permeate into the interior of the wood, and it is difficult to uniformly disperse and fix the second liquid, and the first liquid leached from the wood in the second liquid tank. However, it mixes with the second liquid and reacts easily, the second liquid performance deteriorates, the second liquid tank must be replaced in a relatively short time, and further, the reaction product precipitates in the second liquid. Therefore, it was uneconomical to dispose of it.
