摘要： PURPOSE:To improve the durability and hardness of woody material without impairing the characteristics of wood by a method wherein the woody material is impregnated with epoxidized higher fatty ester and catalyst so as to be added through ring opening to active group of wood. CONSTITUTION:Woody material is impregnated with epoxidized higher fatty ester such as epoxidized linseed oil or the like and catalyst to activate said epoxy group such as tetraisopropoxy titanate or the like and, after that, heated for about 10min at 140 deg.C so as to add said epoxidized higher fatty ester to the active group in the woody material component. Simultaneously, epoxidized higher fatty acids are polymerized each other in gaps in said woody material and solidified. The treated wood veneer has glossy oil-finished outer appearance. No falling out of contents by solvent or the like occurs. Further, the veneer has toughness almost the same as that of untreated green wood.

摘要： PURPOSE:To provided flame retardance by impregnating a timer carboxyesterified with organic polybasic anhydride with alkali inorganic compound water solution, forming metallic salt and fixing the same by metallic crosslinking. CONSTITUTION:A dried timer, with active radicals such as hydroxide contained therein carboxyesterfied by using maleic anhydride as a dibasic anhydride and inorganic polybasic acid such as sccinic anhydride, is impregnated with alkali inorganic compound water solution under the reduced-pressure state and metallic salt is formed in the timer by metal crosslinking. A metal compound is modified in a side chain in the timber component by said process to provide the timber with flame retardance. Further, water-insoluble high molecules are integrated and formed firmly by chemical modification of the timber and metallic crosslinking when impregnated with water solution of polyvalent metallic inorganic salt group, and modified performances can be maintained for a long time.

摘要： PURPOSE:To impart a lumber material with a fire retardant, preservative characteristics, mothproof property, hardness, dimensional stability and the like by impregnating solution containing phosphoric acid or boric acid to a lumber, and after drying, by applying or impregnating, and then curing, epoxidized high grade unsaturated acid ester or the like to the lumber material. CONSTITUTION:A solution is impregnated into a lumber, after drying it subsequently, epoxidized high grade unsaturated acid ester or the like is applied and impregnated into the lumber. Through this process, the epoxy group undergoes ring-opening addition so as to form an ester linkage by the catalytic action of the phosph oric acid or the like, besides, it also produces an etherified linkage with the hydroxyl group in resin and hydroxyamine or the like, and the cure progresses then. Further, the epoxy group of epoxidized high grade unsaturated acid also produces an etherified linkage with the hydroxyl group of a lumber component such as cellulose or the like. As a result, it prevents the eluting out of phosphoric acid and boric acid from the lumber material. Consequently, even under the severe conditions such as water soaking or outdoor exposure, fire retardant, preservative characteristics, and mothproof property can be maintained and dimensional stability can also be improved through the bulking effect to a lumber cell wall.

摘要： PURPOSE:To improve the durability, hardness, toughness and the like of wood without impairing the pretty appearance of the wood by a method wherein the active group such as hydroxyl group or the like in the wood is chemically modified and polymerized by epoxidized higher fatty ester and polybasic acid anhydride. CONSTITUTION:Wood is treated, for example, under reduced pressure by being impregnated with epoxidized higher fatty ester which consists of impregnating liquid which is prepared by adding anhydrous maleic acid to epoxidized soybean oil, and the like. Next, by being heat-treated about one hour at 140 deg.C, the hydroxyl group and the like in the wood component acts as the starter, resulting in developing chemical modification in the wood and simultaneously, in succession, esterifying and polymerizing epoxy group anhydride in order to efficiently and simultaneously perform both the chemical modification treatment and resin pouring treatment. The epoxidized higher fatty eater together with polybasic acid anhydride react with the wood component, resulting in realizing the state as if lubricant enters in the wood component and giving flexibility and toughness to the wood.

摘要： PURPOSE:To subject lignin to solvolysis and to obtain a solution of wood having high concentration useful as various resin raw materials at normal pressure in a middle temperature range in a short time efficiently, by dissolving chemically modified wood in a polyhydric alcohol in the presence of an acid catalyst. CONSTITUTION:For example, a substituent group is introduced into at least part of OH of cellulose, lignin, etc. by a means such as esterification, allylation, etc., to give a chemically modified wood (e.g., sawdust, wood fiber, wood chip, veneer waste, etc.), which is dissolved in a polyhydric alcohol (e.g., ethylene glycol, 1,4-butandiol, glycerin, etc.) in the presence of an acid such as HCl, H2SO4, AlCl3, etc. The dissolution is carried out by using usually 10-100pts.wt. wood based on 100pts.wt. polyhydric alcohol at normal pressure at about 80 deg.C. EFFECT:Chemically modified wood having low degree of substitution is easily solubilized.

摘要： PURPOSE:To obtain a method for industrially easily imparting a water-resistant dimensional stability to a wood-based material. CONSTITUTION:Treating liquid is prepared by compounding a catalyst as a reaction accelerator with a hemiacetal water solution composed of a glyoxal water solution and a 3-8C alkylene glycol. The treating liquid is infiltrated into a wood-based material to wet the wood-based material. The wood-based material in a wet state is heated for crosslinking the treating liquid with the components of the wood-based material. After that, the wood-based material is pressurized and heated by a press for compressing the wood-based material and solidifying the hemiacetal. In this manner, a water-resistant dimensional stable wood-based material superior in resistance to swelling and resistance to shrinking is obtained.
