この発明は繊維強化フェノール樹脂発泡体の表面凹凸模
様付方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a method for providing a textured surface of a fiber-reinforced phenolic resin foam.
従来、建築用壁板として繊維強化フェノール樹脂発泡体
から威る壁板が好適として広く用いられている。Conventionally, wall panels made of fiber-reinforced phenolic resin foam have been widely used as suitable architectural wall panels.
この種材質の壁板は軽量かつ、難燃性に富み、また、繊

する。Wall boards made of this type of material have various advantages, such as being lightweight, highly flame retardant, and, since they are reinforced with fibers, have excellent strength.

く正確な模様付が出来ず、さらに深い凹凸模様も付すこ
とが出来ないと言った問題が有り、また、成形後の切削
加工は切削部分の材料が全く無駄となるばかりでなく、
繊維強化発泡体にあっては表面状態が見苦しくなる問題
が有った。By the way, when adding an uneven pattern to a wall board that is better than the above-mentioned fiber-reinforced phenol resin foam board, the conventional method is to use an uneven mold during press molding, press with this and simultaneously harden it, and process using a router, etc. Possible methods include cutting the surface with a machine to create a pattern, or heating and pressing the surface of a flat plate after molding, but pressing with a mold and molding and hardening means that the resin has a high viscosity. Combined with this, there is a problem that air and gas tend to accumulate in the uneven pattern parts of the mold, making it impossible to create accurate patterns and even deeper uneven patterns. Not only is the material of the cutting part completely wasted, but
Fiber-reinforced foams have a problem in that the surface condition becomes unsightly.
また、成形後の板体にプレスするのは、フェノール樹脂
発泡体は硬度は有する反面脆い性質を有するので組織が
破壊され板材として携帯そのものを維持出来なくなる問
題が有った。Furthermore, pressing the molded plate into a plate has the problem that, although the phenol resin foam has hardness, it also has brittle properties, so the structure is destroyed, making it impossible to maintain the cell phone as a plate.
この発明は上記問題点に鑑み、脆い材質である繊維強化
酸硬化系フェノール樹脂発泡板であっても、これらを破

れたものである。In view of the above-mentioned problems, the present invention has developed a method that can easily create a deep uneven pattern on fiber-reinforced acid-curing phenolic resin foam boards, which are brittle materials, without destroying them. It was made for the purpose of providing.
即ち、この発明の繊維強化フェノール樹脂発泡体の表面
凹凸模様付方法は液状レゾール型フェノール樹脂に充填

凸プレスによりその表面を圧壊し得る圧力で加圧すると
同時に加熱し、前記粉末状レゾール型フェノール樹脂を
硬化させることを特徴とするものである。That is, the method for imparting a pattern on the surface of a fiber-reinforced phenolic resin foam according to the present invention is to add a powdered resol type phenol having a lower reactivity than the resin to a mixture obtained by adding fillers and reinforcing fibers to a liquid resol type phenol resin. A fiber-reinforced phenolic resin foam is molded by adding a resin, and the molded product is pressed with a pressure capable of crushing its surface using a concave-convex press and heated at the same time to harden the powdered resol type phenolic resin. That is.
既述のように、繊維強化フェノール樹脂発泡体は跪く、
−窓以上の圧力を加えて押圧すると、容易に破壊され、
原形を保つことは出来ない。As already mentioned, fiber-reinforced phenolic foam kneels,
- If pressed with more pressure than the window, it will be easily destroyed;
It is not possible to maintain the original shape.
そこで、レゾール型フェノール樹脂の反応性は組成によ

ある。Therefore, we focused on the fact that the reactivity of resol type phenolic resin can be adjusted by changing the composition, and we mixed a resin with lower reactivity with the resin that will become the base resin, and created a resin that will become the highly reactive base resin. First, foam molding is performed, and the surface of the molded product is pressed with a mold with a concavo-convex pattern, and at the same time heated, the resin with low reactivity is thermoset.
このとき、もとの発泡体はプレス圧により凹凸模様表面
に沿って圧壊されるが、これに含まれているフェノール
樹脂が熱により流動化し圧壊部に浸透し、かつ、そのま
まの状態で加熱硬化されるので、硬化完了後はこの樹脂

形成されるのである。At this time, the original foam is crushed along the uneven pattern surface by the press pressure, but the phenolic resin contained in it becomes fluidized by heat and penetrates into the crushed area, and then heat cures in that state. Therefore, after curing is completed, the surface condition is reinforced by this resin, and an uneven patterned surface with excellent strength is formed.
即ち、含まれた粉末状フェノール樹脂がバインダ及び充
填剤となって破壊組織を再び一体化させるのである。That is, the powdered phenolic resin contained serves as a binder and filler to reunite the fractured tissue.
次に、この発明の詳細な説明する。 Next, the present invention will be explained in detail.

繊維強化フェノール樹脂発泡板を成形した。10 parts by weight of a powdered resol type phenolic resin with a curing reaction heat of 150°C was added to a liquid resol type phenolic resin with a curing reaction heat of 100°C, and this was used as a base resin.
0 parts by weight of a filler (talc) and the required amount of blowing agent/curing agent were added, impregnated into 15 parts by weight of glass reinforcing fibers, and then foamed and cured by heating and pressurizing to a density of 500 ktr.
/ci, a fiber-reinforced phenolic resin foam board with a medium diameter of 4.5 cm, a length of 1.8 m, and a thickness of 1 cm was molded.
ついでこれを凹凸差3開 の木目調模様の凹凸金型に配

た。Next, this was placed in a concave-convex mold with a woodgrain pattern with a concavo-convex difference of 3 degrees, and pressed at 10 kg/cd at the same time.
The mold was heated to 50° C., maintained for 30 minutes, and demolded.
得た板材は、表面がきわめて美麗な凹凸模様があられさ

も高かった。The obtained board material had a very beautiful uneven pattern on its surface, had a smooth surface, and had high surface hardness.
また、曲げ試験を行なったところ、曲げ強度200 k
g/cdの強度を有し、壁板として強度に優れることも
判明した。In addition, when a bending test was conducted, the bending strength was 200 k.
It was also found that it had a strength of g/cd and was excellent in strength as a wall board.
