〔産業上の利用分野〕
この発明は木質単板、挽板等の木材の含浸処理方法に関
するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for impregnating wood such as wood veneers and sawn boards.
木材には腐る、燃える、狂う等の欠点があり、さらに床
材等に使用する場合は柔らかく、耐傷性に劣るという欠
点がある。Wood has drawbacks such as rotting, burning, and warping, and furthermore, when used as flooring material, it is soft and has poor scratch resistance.
これらの欠点を解消するために、従来より合成樹脂を木
材内に含浸させるWPC処理が行われている。In order to eliminate these drawbacks, WPC treatment, which impregnates synthetic resin into wood, has been conventionally performed.
WPC処理では、樹脂の含浸率を高くすると、硬度等の
諸物性は向上する反面、表面がいわゆる濡れ色になり、
木質感を損なうという欠点があった。In WPC treatment, increasing the resin impregnation rate improves various physical properties such as hardness, but on the other hand, the surface becomes so-called wet color.
It had the disadvantage of damaging the wood texture.
したがって、この発明の目的は諸物性にすぐれた木゛材
を得ることができる木材の含浸処理方法を提供すること
である。Therefore, an object of the present invention is to provide a method for impregnating wood that can obtain wood with excellent physical properties.
この発明の木材の含浸処理方法は、木材に樹脂を含浸さ
せ、ついでこの樹脂の硬化促進機能を有する木材改質剤
を木材内に含浸させ、前記樹脂を硬化させるものである
。The method for impregnating wood according to the present invention involves impregnating wood with a resin, then impregnating the wood with a wood modifier having a function of accelerating hardening of the resin, and curing the resin.
前記樹脂としては、たとえば取り扱いの容易なメラミン
樹脂等の水溶性の樹脂があげられる。Examples of the resin include water-soluble resins such as melamine resins that are easy to handle.
また、前記木材改質剤としては、互いに反応して不溶性
化合物を形成する2種の無機塩からなる木材改質剤があ
げられる。Furthermore, examples of the wood modifier include wood modifiers consisting of two types of inorganic salts that react with each other to form an insoluble compound.
前記2種の無機塩のうち一方は水溶液中でMg。One of the two types of inorganic salts is Mg in an aqueous solution.
Ca、 、Atl Zn+ Ba等のカチオンイオンを

浸処理され、乾燥により木材中にて不溶性の無機化合物
を生成するものである。2種の改質剤の含浸順序はとく
に制限されるものではない。One generates cation ions such as Ca, , Atl Zn+ Ba, etc., and the other generates anion ions such as sulfate ion, phosphate ion, carbonate ion, etc. in an aqueous solution. These modifiers are impregnated into wood in the form of an aqueous solution, and upon drying produce inorganic compounds that are insoluble in the wood. The order of impregnation of the two types of modifiers is not particularly limited.
この発明における含浸方法としては、加圧含浸、減圧含
浸および常圧浸漬のいずれもが採用可能である。As the impregnation method in this invention, any of pressurized impregnation, reduced pressure impregnation, and normal pressure impregnation can be adopted.
両改質剤の含浸処理後、処理木材を乾燥させることによ
り、これらの改質剤が木材中で反応して不溶性の無機化
合物を形成する。After the impregnation treatment with both modifiers, the treated wood is dried so that these modifiers react in the wood to form insoluble inorganic compounds.

濡れ色になるのを防止することができる。By impregnating wood with the wood modifier, the performance of the wood, such as its antiseptic properties and flame retardancy, is improved. Furthermore, since this wood modifier also functions as a resin curing accelerator, the resin is quickly cured, production efficiency is increased, and the physical properties of the resin (hardness, strength, dimensional stability) are improved. When used in combination with a wood modifier, only a small amount of resin is required to be impregnated, so it is possible to prevent the surface from becoming wet and discolored.
(実施例〕
次に実施例をあげてこの発明の木材の含浸処理方法を説
明する。(Example) Next, the method for impregnating wood of the present invention will be explained with reference to Examples.
実施例1: 米松単板(厚さIOIlm)を減圧釜内に

置した。ついで水溶性樹脂であるメラミン樹脂(固形分
50%)を注入し、木材に含浸させた。Example 1: A Japanese pine veneer (thickness IO Ilm) was placed in a vacuum pot and left under reduced pressure (evacuation below 10 Torr for 1 hour or more). Melamine resin (solid content: 50%), which is a water-soluble resin, was then injected and impregnated into the wood.

and 60°C in warm water containing 1.2 kg of boric acid.
Soaked for an hour. Then, 10 kg of ammonium phosphate and 3.7 kg of boric acid were added per 10ffi.
"C" warm water for 24 hours.
浸漬後、室温水中に24時間浸漬し、可溶な塩を除去し

質木材を得た。After immersion, the sample was immersed in room temperature water for 24 hours to remove soluble salts. Then, it was dried and cured at 100 to 120°C to obtain a modified wood.
実施例2: ナラ単板(厚さ1511m)を使用して実
施例1と同様にして改質木材を得た。ただし、樹脂固形
分は30%とした。Example 2: Modified wood was obtained in the same manner as in Example 1 using oak veneer (thickness: 1511 m). However, the resin solid content was 30%.

色になることもなかった。5. In these Examples, the inorganic salt was impregnated into the wood veneer. The pH in the wood is lower (pH 3-4), and the curing speed of the melamine resin is faster, and what conventionally required 5-6 hours was now able to be cured in 2-3 hours. In addition, properties such as hardness, strength, and dimensional stability based on the melamine resin have been improved, and performances such as antiseptic properties and flame retardancy have also been improved by impregnation with inorganic salts. Furthermore, the surface did not become wet and colored.

る。According to this invention, by impregnating wood with a wood modifier, the performance of the wood, such as its antiseptic properties and flame retardance, is improved. Furthermore, this wood modifier also functions as a resin curing accelerator, so the resin hardens quickly, improving the physical properties of the resin (hardness, strength, dimensional stability), and improving the resin's wood modification properties. Since it is used in combination with a resin, the amount of resin impregnated is reduced and the surface becomes wet and the wood texture is prevented from being damaged.
