Description
本発明はあと施工アンカーに用いる樹脂カプセルアンカーの製造方法に関する。 The present invention relates to a method for producing a resin capsule anchor used for a post-construction anchor.
従来、コンクリート等の構造物にあと施行でボルトや鉄筋を取り付けるための2成分系からなる樹脂カプセルアンカーの製造方法は、容器内に硬化剤と樹脂とを分離層を形成して充填したり、あるいは容器内に硬化剤と樹脂とを分離層を2層以上交互に積層して充填したり、あるいはまた容器内に樹脂や骨材を充填し容器外に硬化剤を被覆することが知られている(例えば、特許文献1、特許文献2、特許文献3参照)。
容器内に硬化剤と樹脂とを分離層を形成して充填したり、あるいは容器内に硬化剤と樹脂とを分離層を2層以上交互に積層して充填する方法は、容器内に2成分以上を充填する必要があるため、製造工程が複雑になる問題があった。また、容器外に硬化剤を被覆する場合、従来の方法では硬化剤の量が不均一である、硬化剤の歩留まりが悪い、生産性が低い等の問題があり、安定した品質の製品を効率的に連続製造することは困難であった。
A method in which a separating layer is formed and filled with a curing agent and a resin in a container, or two or more separation layers of a curing agent and a resin are alternately stacked and filled in a container. Since it is necessary to fill the above, there is a problem that the manufacturing process becomes complicated. In addition, when coating the curing agent outside the container, there are problems such as the amount of curing agent being non-uniform in the conventional method, poor yield of curing agent, low productivity, etc. Therefore, continuous production was difficult.
本発明は、樹脂と硬化剤の十分な混合性を得られる構造の樹脂カプセルアンカーを効率的に製造でき連続生産に適したプロセスを提供することを目的とするものである。 An object of this invention is to provide the process suitable for continuous production which can manufacture efficiently the resin capsule anchor of the structure which can obtain sufficient mixing property of resin and a hardening | curing agent.
本発明者らは、上記課題を解決するために鋭意研究を重ねた結果、樹脂の入った容器を回転させながら外周にスラリー状硬化剤を塗布して巻きつけて乾燥させることで連続生産に適した樹脂カプセルアンカー製造プロセスが得られることを発明するに至った。
すなわち、本発明は下記の通りである。
1.容器を回転させながら外周にスラリー状硬化剤を巻きつけて乾燥させることを特徴とする樹脂カプセルアンカーの製造方法。
As a result of intensive research to solve the above-mentioned problems, the present inventors applied a slurry-like curing agent to the outer periphery while rotating a container containing a resin, and wound and dried to make it suitable for continuous production. Invented that a resin capsule anchor manufacturing process is obtained.
That is, the present invention is as follows.
1. A method for producing a resin capsule anchor, characterized by winding a slurry-like curing agent around an outer periphery while rotating a container and drying the container.
本発明により、樹脂カプセルアンカーの連続生産に適した製造プロセスの提供が可能になった According to the present invention, it has become possible to provide a manufacturing process suitable for continuous production of resin capsule anchors.
以下、本発明について、好ましい態様を中心に、具体的に説明する。
本発明の製造方法は、樹脂あるいは樹脂及び骨材の入った容器を回転させながら外周にスラリー状硬化剤を塗布して巻きつけて乾燥させることを特徴とする。
従来、反応性樹脂と硬化剤を分離して容器に収納し、コンクリートあと施工時にアンカーボルト等の回転や打撃で容器を破壊させ樹脂と硬化剤とが混合・反応してコンクリートとボルト等を固着させるため容器内部に樹脂をまた場合によっては骨材をも入れてその容器外側に硬化剤を配置する方法がとられているが樹脂と硬化剤は化学量論的な適量を収納しておく必要がある。
Hereinafter, the present invention will be specifically described focusing on preferred embodiments.
The production method of the present invention is characterized in that a slurry-like curing agent is applied to the outer periphery of a container containing resin or resin and aggregate while being rotated, and is wound and dried.
Conventionally, reactive resin and hardener are separated and stored in a container, and when concrete is installed, the container is broken by rotation or blow of anchor bolts, etc., and the resin and hardener are mixed and reacted to fix the concrete and bolt etc. In order to prevent this, a method of placing a resin inside the container and possibly an aggregate and placing a curing agent on the outside of the container is used, but it is necessary to store a stoichiometrically appropriate amount of the resin and the curing agent. There is.
特に硬化剤は過酸化ベンゾイル等の粉体のものが主に用いられているために定量的な充填と且つ効率的生産を行う必要があり、発明者らは樹脂の充填された円筒容器の軸を中心に回転させてその外側に一定濃度の硬化剤スラリーを、好ましくは定量ポンプで供給付着させることにより容器外周の周方向に均一の厚さに塗布される、さらにこの回転を維持しながら乾燥させることにより一定量の硬化剤が周方向均一な厚さで付着し連続的に作られることを発明するに至った。
容器はガラスやプラスティック等硬いものがよく、円筒状であれば直管でも絞り部を有した管でも良い。
In particular, since a hardener such as benzoyl peroxide is mainly used, it is necessary to perform quantitative filling and efficient production. The hardener slurry with a constant concentration is applied to the outside of the container, preferably with a metering pump, and is applied to the outer circumference of the container to a uniform thickness. Drying while maintaining this rotation As a result, the inventors have invented that a certain amount of the curing agent adheres with a uniform thickness in the circumferential direction and is continuously produced.
The container is preferably made of a hard material such as glass or plastic, and may be a straight tube or a tube having a throttle portion as long as it is cylindrical.
硬化剤を容器に巻きつけるときの回転数は容器の直径と硬化剤スラリー濃度により容器周方向全周に硬化剤が均一に広がり塗布されるように調整するのが良く、好ましくは容器外径10〜18mmのとき80〜180rpm、より好ましくは100〜160rpm、さらに好ましくは120〜140rpmである。
硬化剤スラリー粘度が高いときは回転数を下げて、逆に硬化剤スラリー粘度が低いときは回転数を上げることが好ましい、また極端に回転数を上げすぎると硬化剤の片付きを起こし、逆に極端に低すぎると硬化剤が容器から垂れてしまう現象が見られる。
硬化剤スラリー粘度は、0.5〜3Pa・sが好ましく0.5Pa・s以上にすると回転中のガラス管凹部よりのスラリーの垂れを防止することができる。
The number of rotations when the curing agent is wound around the container is adjusted so that the curing agent spreads uniformly and is applied to the entire circumference of the container according to the diameter of the container and the concentration of the curing agent slurry. When it is -18 mm, it is 80-180 rpm, More preferably, it is 100-160 rpm, More preferably, it is 120-140 rpm.
When the viscosity of the curing agent slurry is high, it is preferable to decrease the rotation speed, and conversely, when the viscosity of the curing agent slurry is low, it is preferable to increase the rotation speed. If it is too low, a phenomenon that the curing agent droops from the container is observed.
The viscosity of the curing agent slurry is preferably 0.5 to 3 Pa · s, and if it is 0.5 Pa · s or more, dripping of the slurry from the rotating glass tube recess can be prevented.
一方、3Pa・s以下にすると硬化剤の偏りが防止でき周方向に硬化剤を均一に配置することができる。
しかし、この最適回転数は硬化剤に用いるスラリー濃度とスラリー中の固体成分の粒径、温度等により左右されるため実質的に容器に硬化剤が片付きをせず垂れない回転数を選択することが良い。
硬化剤スラリーを供給する定量ポンプ吐出口は回転する容器の外周近辺の上部にノズルで近接している構造を有するのが良く、定量ポンプの供給速度は容器が一回転する間に一回の供給が終了する程度が良いが必ずしも正確に合致しなくても塗布後容器が回転する間に周方向に広がり均一な厚みが形成される。
On the other hand, when the pressure is 3 Pa · s or less, the unevenness of the curing agent can be prevented and the curing agent can be uniformly arranged in the circumferential direction.
However, since this optimum rotation speed depends on the slurry concentration used for the curing agent, the particle size of the solid component in the slurry, the temperature, etc., select the rotation speed at which the curing agent does not drip substantially without getting stuck on the container. Is good.
The metering pump discharge port for supplying the hardener slurry should have a structure that is close to the upper part of the outer periphery of the rotating container by a nozzle, and the metering pump is supplied once during the rotation of the container. However, even if it does not necessarily match exactly, it spreads in the circumferential direction while the container is rotated after application, and a uniform thickness is formed.
また、定量ポンプの塗布位置である上記ノズルは容器の軸方向に間歇的に横移動し移動中は硬化剤スラリーを供給せず横移動停止中に硬化剤スラリーを供給する方法と連続して横移動し移動中連続して硬化剤スラリーを供給する方法とがあり製造する樹脂カプセルの形態により選定することが出来る。
さらに、この方法はガラス容器を用いる場合ガラス容器に樹脂をあるいは樹脂と骨材を充填したあと火炎で溶封、その後硬化剤をガラス容器外側に巻きつけ付着させるため製造過程で硬化剤の主成分である熱分解性の過酸化ベンゾイルが火炎に近づくことがないので安全である。
Further, the nozzle, which is the application position of the metering pump, moves laterally intermittently in the axial direction of the container. There is a method of moving and supplying the curing agent slurry continuously during the movement, and it can be selected according to the form of the resin capsule to be manufactured.
Furthermore, in this method, when a glass container is used, the glass container is filled with resin or resin and aggregate, then sealed with flame, and then the curative is wound around and attached to the outside of the glass container. This is safe because the pyrolytic benzoyl peroxide is not close to the flame.
硬化剤は、スラリー状で乾燥すると容器外周に適度な硬さで付着する成分を含んでいると良い、具体的には過酸化ベンゾイルに感度低下のための硫酸カルシウム等の無機物質を加えた混合物に合成樹脂ラテックス、水溶性バインダー等を加えた水スラリーを作りそれを定量ポンプで回転する容器外側に供給・塗布して引き続き乾燥すると輸送等の取り扱いでは破壊せず施行時には容易に破壊し樹脂と混合されるような適度な硬さを持った硬化剤が得られる。
硬化剤スラリーの組成は、過酸化ベンゾイル30〜50部、硫酸カルシウム50〜70部、合成樹脂ラテックス固形分1〜3部、水20〜40部に少量のシリカ系体積増量剤、水溶性バインダーを混合するのが好ましい。
The curing agent should contain a component that adheres to the outer periphery of the container with an appropriate hardness when dried in a slurry state. Specifically, a mixture of benzoyl peroxide and an inorganic substance such as calcium sulfate for reducing sensitivity. Make a water slurry with synthetic resin latex, water-soluble binder, etc. added to the outside of the container that rotates with a metering pump, and then dry it. A curing agent having an appropriate hardness to be mixed is obtained.
The composition of the curing agent slurry is 30-50 parts of benzoyl peroxide, 50-70 parts of calcium sulfate, 1-3 parts of synthetic resin latex solids, 20-40 parts of water with a small amount of silica-based volume extender and water-soluble binder. It is preferable to mix.
容器は、円筒状であれば直管でも絞り部を有した管でも良く、絞り部を有しているものは間歇的に横移動したノズルから供給される硬化剤スラリーは絞り部に塗布される様にメカニカル的にコントロールされていることが好ましく、直管の場合はノズルから供給される硬化剤スラリーは連続した横移動中に連続して硬化剤スラリーを供給する様にメカニカル的にコントロールされている構造を有していることが好ましい。
乾燥は、回転する容器の外側に硬化剤スラリーを定量ポンプで供給・塗布させた後さらにこの回転を維持しながらスラリー中の水分を蒸発させるために温度をかけた熱風乾燥機へ送りこみ連続的に乾燥することが好ましい。
The container may be a straight pipe or a pipe having a throttle part as long as it is cylindrical, and those having a throttle part apply the curing agent slurry supplied from the nozzle moved laterally intermittently to the throttle part. In the case of a straight pipe, the hardener slurry supplied from the nozzle is mechanically controlled so as to continuously supply the hardener slurry during continuous lateral movement. It is preferable to have a structure.
Drying is performed by supplying the curing agent slurry to the outside of the rotating container with a metering pump and then feeding it to a hot air dryer that is heated to evaporate the water in the slurry while maintaining this rotation. It is preferable to dry it.
ガラス管内に充填する樹脂は硬化性の不飽和ポリエステル樹脂、エポキシアクリレート樹脂などである。
次に、実施例及び比較例によって本発明をさらに詳細に説明する。
The resin filled in the glass tube is a curable unsaturated polyester resin, epoxy acrylate resin, or the like.
