本発明は硬質板を積層するに際して接着層への
気泡の混入あるいは板表面のひけの発生などの欠
陥を生じないよう工夫した全面接着方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a full-surface bonding method devised to avoid defects such as the inclusion of air bubbles in the adhesive layer or the occurrence of sink marks on the surface of the plates when laminating hard plates.
従来２枚のガラスあるいはガラスとポリメチル
メタクリレート板等を接着する方法として一方の
表面に接着剤の溜りを形成し、つぎに他方の表面
をその溜りに接触させ、押圧して接着剤が２表面
の間の空間全体を満たすようにさせるなどの方法
がとられてきた。 Conventionally, the method of bonding two pieces of glass or glass and a polymethyl methacrylate plate, etc. is to form a pool of adhesive on one surface, then bring the other surface into contact with the pool and press it to spread the adhesive onto the two surfaces. Methods have been taken to fill the entire space between them.
しかしながらこれらの方法では接着層に気泡が
混入しやすく、殊に大面積の板を接着する場合は
一層これを除くことは困難で不良率が多かつた。
すなわち、上面から押圧し、空気は周辺から逃が
すように中央部から周辺に向つて接着剤を満たし
ていくよう細心の注意と熱練を要する。しかし、
一旦接着剤内に混入した気泡はいかに強く押圧し
ても脱き難く、殊に板の厚みが大で面積が広くな
ると不可能に近くなる。 However, with these methods, air bubbles are likely to be mixed into the adhesive layer, and it is even more difficult to remove air bubbles, especially when bonding large-area plates, resulting in a high rate of defects.
In other words, it is necessary to apply pressure from the top and to fill the adhesive from the center to the periphery so that air escapes from the periphery, requiring careful attention and kneading. but,
Once air bubbles are mixed into the adhesive, it is difficult to remove them no matter how strongly you press them, and it becomes nearly impossible to remove them, especially if the plate is thick and has a large area.
また予め接着層を設けて注入する方法も考えら
れるが、開口部より接着剤を注入する場合、通常
の接着剤は粘度が比較的高く、しかも２面間の間
隔が狭いため、注入が困難であつて完全充填が行
なわれ難いため、やはり大面積や多層接着などは
容易でない。 Another option is to prepare an adhesive layer in advance and inject it, but when injecting adhesive from the opening, it is difficult to inject because the viscosity of ordinary adhesives is relatively high and the distance between the two surfaces is narrow. Since complete filling is difficult in such cases, it is not easy to bond large areas or bond multiple layers.
従つて現状では接着剤の組成や粘度限界も狭い
ことや、大面積シートの接着では失敗する確率が
高く、たとえ成功しても一部のかな気泡のためト
リミングロスを生じ、材料の損失も無視できない
ものになつていた。 Therefore, at present, the composition and viscosity limits of adhesives are narrow, and there is a high probability of failure when bonding large area sheets, and even if successful, trimming loss occurs due to some small air bubbles, and material loss is ignored. It had become something I couldn't do.
本発明はかかる欠点を除いた新規な貼合せ板を

硬質板を一定の間隔で保持するとともに傾斜さ

さに調整し、接着剤を硬化せしめることを特徴と
する全面接着方法である。 The present invention relates to a method of manufacturing a new laminated board that eliminates such drawbacks, and the present invention involves holding two or more hard boards at a constant interval and tilting them, and the gap around them is filled with an opening provided on the upper side. In this method, the adhesive is injected from the upper opening after sealing the hard plate except for the upper part of the plate. The entire surface is characterized in that the hard plates are expanded to a predetermined finished thickness, and after the adhesive is injected, these gap retaining materials are removed, the spacing between the hard plates is adjusted to a predetermined thickness, and the adhesive is cured. This is an adhesion method.
この方法をポリメチルメタクリレート板あるい
はガラス板など透明硬質板の面接着に適用した場
合、２枚もしくは２枚以上の多層であつても、大
面積、厚板の如何にかかわらず、気泡の混入やひ
けの発生のない完全な貼り合せ板を容易に得るこ
とができる。 When this method is applied to the surface adhesion of transparent hard plates such as polymethyl methacrylate plates or glass plates, no air bubbles may be mixed in, regardless of whether the plate is large or thick, even if it is two or multiple layers. A perfect laminated board without sink marks can be easily obtained.
以下、本発明の方法を第１図、第２図によつて
具体的に説明する。 The method of the present invention will be specifically explained below with reference to FIGS. 1 and 2.
傾斜角度を調節できる装置９を有する作業台１
０に全面接着をする板１，２をのせる。 Workbench 1 with device 9 for adjusting the tilt angle
Place plates 1 and 2 to which the entire surface is to be glued on 0.
その際板の傾斜は３〜90度の範囲で実施可能で
あるが、操作上あるいは接着剤の液圧によつて板
が膨らむのを防止するうえから傾斜角を低く保つ
のが望ましい。通常５〜45度の傾斜が好ましい。
接着剤の注入中は空気の置換具合、接着剤の注入
速度あるいは混入気泡があればその脱泡具合等に
合わせて板の傾斜角度を適宜増減することができ
る。 At this time, the inclination of the plate can be carried out within the range of 3 to 90 degrees, but it is desirable to keep the inclination angle low for operational reasons or to prevent the plate from swelling due to the hydraulic pressure of the adhesive. An inclination of 5 to 45 degrees is usually preferred.
During the injection of the adhesive, the inclination angle of the plate can be increased or decreased as appropriate depending on the degree of air replacement, the rate of injection of the adhesive, the degree of degassing of air bubbles if any are present, etc.
これらの周辺は接着層の間隙保持と接着剤の漏
洩防止のため弾性材料のパツキン３を置く。弾性
材料としては天然ゴム、合成ゴム、軟質塩化ビニ
ル、ポリエチレン（PE）などが適し、その断面
形状は任意でよいが本発明の工程上、中空のチユ
ーブ状が最も好ましい。 A packing 3 made of an elastic material is placed around these to maintain the gap between the adhesive layers and prevent leakage of the adhesive. As the elastic material, natural rubber, synthetic rubber, soft vinyl chloride, polyethylene (PE), etc. are suitable, and the cross-sectional shape may be arbitrary, but a hollow tube shape is most preferable for the process of the present invention.
この弾性材料の材質はJISA硬度計による硬さ
が中空チユーブ状の場合40〜95、中実の場合は断
面形状により変るが５〜60程度のものが適する。
軟質チユーブの場合、太さは接着層厚に応じて決

10mmＯ／、肉厚0.5〜２mm程度が好ましい。この様
な軟質チユーブによつて注入時の間隙を所定の仕
上り厚さよりも広く保持するため、予めチユーブ
には約３Kg／cm2以内の圧縮空気を封入しておくの
が有効である。封入する空気圧は板厚や積層枚数
に応じてかかる重量が多くなる程大きくすること
が望ましい。なお空気圧縮装置がない場合や中実
の弾性材料からなるパツキンの場合は周辺の間隙
を拡げるべく周辺間隙保持材５をおくことによつ
ても可能である。 Suitable materials for this elastic material have a hardness measured by a JISA hardness meter of 40 to 95 in the case of a hollow tube shape, and 5 to 60 in the case of a solid shape, although this varies depending on the cross-sectional shape.
In the case of soft tubes, the thickness is determined according to the adhesive layer thickness, but for normal soft PVC, the outer diameter is 3~
Preferably, the thickness is about 10 mmO/, and the wall thickness is about 0.5 to 2 mm. In order to keep the gap during injection wider than a predetermined finished thickness using such a soft tube, it is effective to fill the tube with compressed air of up to about 3 kg/cm 2 in advance. It is desirable to increase the air pressure to be sealed as the weight increases depending on the thickness of the plate and the number of laminated sheets. Note that if there is no air compression device or if the packing is made of a solid elastic material, it is also possible to provide a peripheral gap retaining material 5 to widen the peripheral gap.
また大面積シートの接着においては硬質板全体
の間隔を均一に保つために上部開口部から中央部
間隙保持材料４を１本ないし２本以上挿入する

以上挿入することが望ましい。なお、合成樹脂板
の全面接着においては異質の金属材料を使う方
が、間隙保持材として挿入、抜きとりの作業性の
点でより望ましい。 In addition, when bonding large-area sheets, one or more central gap-maintaining materials 4 are inserted from the upper opening in order to maintain uniform spacing between the entire hard plates. Any hard synthetic resin material such as a hard PVC board or various metal materials that can withstand some pressure may be used. If the area of the hard plate is large, it is desirable to insert two or more. In addition, when bonding the entire surface of a synthetic resin plate, it is more desirable to use a different metal material as a gap retaining material in terms of workability in inserting and removing the material.
中央部間隙保持材の長さは少なくともシートの
傾斜方向長さの中点付近まで入るようにすれば接
着剤の注入を容易にし、かつ、偏肉を少なくさせ
ることができる。また挿入、抜きとりに際しては
先端のエツジを丸くし、かつ、注入する同一の液
状接着剤を塗布しておくことによつて極めて容易
に操作できる。 If the length of the center gap retaining material is set to at least the midpoint of the length of the sheet in the direction of inclination, injection of the adhesive can be facilitated and uneven thickness can be reduced. Further, insertion and removal can be performed extremely easily by rounding the edge of the tip and applying the same liquid adhesive to be injected.
こうしてセツトされ、全体を傾斜させた状態で
所定の接着層厚に応じて計量された接着剤を上部
開口部から注入する。この場合、第１図のように

る方法にすればより一層注入を容易にすることが
できる。更に他の注入具を使用することも有効で
ある。 Once set in this manner, and with the entire structure tilted, an adhesive measured according to a predetermined adhesive layer thickness is injected from the upper opening. In this case, injection can be made even easier by making the inserted central gap retaining material 4 hollow as shown in Figure 1, connecting the soft tube 7 and the storage tank 8, and applying appropriate hydraulic pressure. Can be done. Furthermore, it is also effective to use other injection devices.

できる。 The adhesive may be a liquid polymerization-curing adhesive, but for laminating transparent hard plates, a polymerizable adhesive containing methyl methacrylate in a monomeric or partially polymerized state, or methyl A single body containing a dissolved solid polymer of methacrylate is preferable, and if necessary, a plasticizer of methyl methacrylate, a crosslinking agent, a photosensitizer,
