本発明は、ウレタンプレづ？リフ−中に木粉を加えた弾
性発泡体の製造方法に関する。[Detailed Description of the Invention] The present invention is based on urethane plastic. This invention relates to a method for producing an elastic foam in which wood flour is added to the rift.

が安定しない。Conventionally, this type of foam has been made by mixing sawdust, rice bran, and starch in a urethane prepolymer and foaming the mixture. However, the purpose of this single foam is simply to improve physical properties or reduce costs, and is not intended to be used for new purposes. Furthermore, since additives such as sawdust have large particle sizes, they are unevenly dispersed in the foam, resulting in unstable properties.

発泡体を見出し、本発明を完成するに至った。As a result of conducting research to uniformly disperse additives and effectively bring out the properties of the additives, the inventor identified the polyurethane stock solution and determined that the properties of the additives were limited to fine wood powder. They discovered an elastic foam that has both the properties of foam and wood flour, and completed the present invention.

粉が均一に分散した弾性発泡体を製造する方法である。That is, in the present invention, 20 to 500 parts by weight of water and 20 to 500 parts by weight of fine wood are added to 100 parts of a urethane prepolymer (polyurethane stock solution) prepared by heating and mixing a polyol containing 15% by weight or more of ethylene oxide and an organic incyanate. In this method, 5 parts by weight or more of wood powder is added and foam molded to produce an elastic foam in which wood powder is uniformly dispersed.
以下本発明方法を詳細に説明する。The method of the present invention will be explained in detail below.

発泡成形する方法である。The present invention is a method of foam molding a urethane prepolymer by adding water and wood flour.

レンオキサイドの阻が多くなると粘性が高くなり、作業
性が悲くなるので好寸しくは１５〜６０重量％とする。The urethane prepolymer is obtained by heating and mixing a polyol containing 15% by weight or more of ethylene oxide and a friend's isocyanate. Examples of starting materials for synthesizing this polyol include ethylene glycol, diethylene glycol, clopylene glycol, nogropylene glycol, butylene glycol, hexylene glycol (bifunctional) glycerin, trimethylolpropane, trimethylolethane, 1.2.6hexanetriol. Examples include (trifunctional) pentaerythritol, α-methyl glycoside, ethylenesoamine (tetrafunctional), diethylenetriamine, sorbitol, sucrose, and the like. Ethylene oxide in this polyol is added to impart hydrophilicity to the urethane prepolymer. The reason why ethylene oxide is limited to 15% by weight or more is that if it is less than this, it becomes steamy and cannot react with a large amount of water, and it is difficult to mix wood flour uniformly. In this case, if the amount of ethylene oxide increases, the viscosity increases and workability becomes poor, so the preferred amount is 15 to 60% by weight.
このポリオールと加熱混合する有機インシアネートとし
て、例えばトリレンジイソシアネート、ナフタレンジイ
ンシアネート、ノフェニルメタンジインシアネート、キ
シレンイソシアネートなどが挙げられる。Examples of the organic incyanate to be mixed with this polyol under heat include tolylene diisocyanate, naphthalene diisocyanate, nophenylmethane diisocyanate, and xylene isocyanate.
ポリオールと有機イソシアネートとの加熱混合は常法に
従っておこない、例えば６０〜１．００℃で２〜５時間
攪拌しつつ反応させればよい。The heating and mixing of the polyol and the organic isocyanate may be carried out according to a conventional method, for example, the reaction may be carried out at 60 to 1.00° C. with stirring for 2 to 5 hours.

以上の細かい木粉を５重量部以上加えて発泡成形する。To 100 parts by weight of the urethane prepolymer thus obtained, 20 to 500 parts by weight of water and 5 parts by weight or more of fine wood flour of 20 or more meshes are added and foam molded.

木粉の添加方法は、予じめウレタンプレ、ＪＰ ＩＪマ
マ−入れてもよいし、水に入れてもよい。又多量の場合
、両方に入れてもよい。Water is not limited to water alone, and may also be polymer latex, other aqueous dispersions, aqueous slurries, and the like. The reason why the amount of water added is limited to the above range is that if it is less than 20 parts by weight, the reaction will be poor and it will be difficult to form a foam.If it is more than 5'00 parts by weight, the expansion ratio will be extremely poor. In the present invention, 30 to 300
Parts by weight are preferably O. The quality of the wood flour added to the urethane prepolymer is appropriately selected depending on the application. For example, when used as a medium for cultivating shiitake mushrooms, wood powder such as shiitake is used, and when used as the core of footwear or cushions, cork powder is used. The reason why we limited the wood flour particles to fine particles of 20 mesh or more is that if the particles are too thick, the wood flour tends to disperse unevenly.
Moreover, the effect of adding wood flour, which has a small ratio of surface area to amount added, is not sufficient. The reason why the amount added is limited to 5 parts by weight or more is that if it is less than this, the effect of adding wood flour will not be sufficiently obtained. The amount of wood flour added varies depending on the application, but for example, it is preferably 10 to 60 parts by weight for mushroom culture medium, seedling raising, and breeding medium, and 10 to 100 parts by weight for footwear and cushion cores. The powder may be added in advance by adding urethane pre, JP IJ mom, or into water. If the amount is large, it may be added to both.
このように水と木粉とを添加したウレタンプレポリマー
の発泡成形方法は、これらを攪拌した後常温、常圧下で
数分間放置しておくことにとしない。なお水と木粉とと
もに必要に応じてシリコン油（整泡剤）、インシアネー
ト（架橋剤）、その他見泡剤を添加してもよい。ただし
この方法ではこれらを添加しなくとも十分均一な弾性発
泡体が得られる。In this method of foam molding a urethane prepolymer to which water and wood flour have been added, the mixture is not stirred and then left to stand for several minutes at room temperature and pressure. In addition to water and wood flour, silicone oil (foam stabilizer), incyanate (crosslinking agent), and other foam control agents may be added as necessary. However, with this method, a sufficiently uniform elastic foam can be obtained without the addition of these materials.
以上の如くこの方法によればエチレンオキサイドを含ん
だウレタンプレポリマーに親水性があシ、多量の水と安
定して反応するので、木粉を入れても均一に発泡成形す
ることができる。As described above, according to this method, the urethane prepolymer containing ethylene oxide has hydrophilic properties and reacts stably with a large amount of water, so even if wood flour is added, uniform foam molding can be performed.
しかも木粉の粒子が細かいので、発泡体中に細かく分散
し、発泡体の性質を均一なものとすることができる。し
かも得られた弾性発泡体は、弾性発泡体の性質と木粉の
性質とを兼ね備えたものとなる。即ち弾性発泡体は、軽

任意の形状にカット、加工し易い。更に通気性、保温性
がある。一方木粉を均一に分散することにより、発泡体
の硬度を任意に調節でき、又木の性質を持たすことがで
きる。Moreover, since the wood flour particles are fine, they can be finely dispersed in the foam, making the properties of the foam uniform. Moreover, the obtained elastic foam has both the properties of elastic foam and wood flour. That is, the elastic foam is lightweight and easy to carry. It is also easy to cut and process into any shape depending on the purpose of use. It also has breathability and heat retention. On the other hand, by uniformly dispersing wood flour, the hardness of the foam can be adjusted as desired, and it can also have the properties of wood.
このような性質を有する発泡体は、例えば次のような用
途にきわめて有用である。Foams having such properties are extremely useful, for example, in the following applications.
即ち木材と比べて軽量となり、丑だ加工も容易であるの
で、この発泡体を椎茸等のきのこ栽培の培地として使用
できる。また軽量で所望の形状に加工できるため、育苗
、育種等の培地として有効である。更に木粉の量により
発泡体の硬さを調節でき、通気性、保温性を有するので
、履物、クッションの中芯として従来のコルクに代えて
使用することができる。That is, this foam can be used as a medium for cultivating mushrooms such as shiitake mushrooms, since it is lighter than wood and can be easily processed. In addition, it is lightweight and can be processed into a desired shape, making it effective as a medium for raising seedlings, breeding, etc. Furthermore, the hardness of the foam can be adjusted by adjusting the amount of wood flour, and since it has breathability and heat retention properties, it can be used in place of conventional cork as the core of footwear and cushions.
以上説明したように本発明によれば、親水性を有するウ
レタンゾレ７Ｊ？リマーを用い、細かい木粉を添加して
均一に分布さすることによシ、発泡体に木粉の持つ性質
を付加させ、新らしい用途に有効に利用できる。As explained above, according to the present invention, the hydrophilic urethane sole 7J? By adding fine wood flour and distributing it uniformly using a reamer, the properties of wood flour can be added to the foam and it can be effectively used for new applications.
