この発明は、未加硫シリコーンゴムに連続的に粉体を塗
布する方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a method for continuously applying powder to unvulcanized silicone rubber.
（従来技術とその問題点）
従来、接着性、付着性のあるものをコイル状、ないし渦
巻状に巻いた場合に、接触面が密着してしまい、コイル
状ないし渦巻状から次工程（例えば押出成形、射出成形
など）に適した状態にする際の作業性が悪くなることが
あり、これを防ぐために、コイル状、渦巻状に巻きとる
前に各種の粉体を付着させることによりこの現象を防止
してきた。(Prior art and its problems) Conventionally, when an adhesive or adhesive material is wound into a coil or spiral shape, the contact surfaces are in close contact with each other, and the coiled or spiral shape cannot be used in the next process (for example, extrusion). In order to prevent this, various types of powder are applied to the product before winding it into a coil or spiral shape to prevent this phenomenon. It has been prevented.
例えば連続的に成形された棒状、帯状などの未加硫シリ
コーンゴムをコイル状ないし渦巻状にして、保存または
輸送したのち、コイル状ないし渦巻状から解いて、次工
程に用いようとすると、接触面の粘着のために、欠損を
生じたり、作業が煩雑になったり、作業の中断などが発
生したりする。For example, unvulcanized silicone rubber in the form of a continuously formed rod or band may be coiled or spirally stored or transported, and when it is uncoiled or used in the next process, contact may occur. Adhesive surfaces can cause defects, complicate work, and interrupt work.
そこで、そのようなことなどを防ぐために、剥離性の優
れた粉体を表面に塗布した後、コイル状ないし渦巻状に

ぞれ問題点があった。Therefore, in order to prevent such a problem, it is necessary to apply a powder with excellent releasability to the surface and then form it into a coiled or spiral shape. However, each of the conventional coating methods has had its problems.
例えば、未加硫シリコーンゴムへの粉体の塗布は、作業
者が手で未加硫シリコーンゴムへの粉付けをする方法と
、粉体をホッパー等に入れロータリーバルプ等により上
から粉体をまぶして付着させる方法とがあった。前者は

法では、上面のみ塗布可能であるが、側面および下面は
、作業者が手で打粉する必要があった。また両方法とも
作業者による作業のため、作業者によっても付着量が異
なっていた。For example, powder can be applied to unvulcanized silicone rubber by a worker manually applying the powder to the unvulcanized silicone rubber, or by placing the powder in a hopper or the like and applying the powder from above using a rotary valve or the like. There was a method of sprinkling and adhering. The former is all work done by a worker, and the latter is, for example, as shown in FIG. Powder 14 is applied onto the top surface via rotary pulp 11, and with this method, only the top surface can be coated, but the side and bottom surfaces must be powdered by hand by the worker. . Furthermore, since both methods were performed by workers, the amount of adhesion differed depending on the worker.
これに対し、作業者によらない粉体塗布方法としては、
容器に粉体を十分に入れ、そこに連続した未加硫シリコ

出されている。この方法は、初めはよいが、粉体が静止
しているために、連続した未加硫シリコーンゴムに付着
した粉体量がある量に達すると、容器内の粉体量が不足
し、上面、側面に粉体が接触しなくなる。そのまま作業
を続けると、そのうち下面も接触しなくなり、作業者が
粉体をまぶしてやらなければならないという欠点があっ
た。また、容器内の粉体量を、常に一定に保つ必要があ
った。On the other hand, as a powder application method that does not depend on the operator,
Methods have been devised to apply the powder by filling a container with the powder and passing a continuous unvulcanized silicone rubber through it. This method is good at first, but since the powder is stationary, when the amount of powder adhering to the continuous unvulcanized silicone rubber reaches a certain amount, the amount of powder in the container becomes insufficient, and the upper surface , the powder will no longer come into contact with the sides. If the work continued, the bottom surface would eventually come into contact with the surface, and the worker would have to cover it with powder. In addition, it was necessary to always keep the amount of powder in the container constant.

ある。(Means for Solving the Problems) As mentioned above, the conventional methods have their own drawbacks. The present invention provides a method of applying powder by fluidizing the powder with a gas, suspending the powder around unvulcanized silicone rubber, and continuously passing the powder through the fluidized powder. It is something that

る。(Example) The present invention will be explained based on FIG. 1 showing an example of an apparatus for carrying out the method of the present invention. A porous +ffl 2 is preferably attached to the lower part of the fluidization tank 1, and a compressed fluid tank 3 is provided below it. A gas such as compressed air or nitrogen gas is pressurized into the compressed fluid tank 3 through an inflow pipe 8 .

を行う。Powder such as talc is placed in a fluidization tank 1, and gas from a compressed fluid tank 3 (of course, it is not limited to this and any other fluid can be used) is passed through a perforated plate 2 in the illustrated example. By flowing into the powder, the powder is uniformly fluidized. A roller 4 is installed in the fluidization tank 1 to roll the continuous unvulcanized silicone rubber 5 into the fluidized powder 5.
It is restrained from above so that it does not come out. In order to prevent powder from scattering outside the tank, a cover 7 is installed and an exhaust lower 1 is attached to this, and by connecting a dust collector or bag filter, etc., powder can be collected or dispersed. Prevent.
連続した未加硫シリコーンゴム５を、このように流動化
されている粉体６の中に、図示の如く通過させることに
より、その表面に粉体を付着させる。By passing a continuous unvulcanized silicone rubber 5 through the fluidized powder 6 as shown in the figure, the powder is adhered to the surface thereof.

形されたものもあり、なんら限定はない。The shape of the continuous unvulcanized silicone rubber used at this time is typically belt-shaped, rod-shaped, etc., but is not limited to these, and the cross-sectional shape may also be triangular,
In addition to rectangular and circular shapes, there are also shapes molded by extrusion into irregular shapes such as L-shapes and U-shapes, and there are no limitations.
なお、粉体を流動化させるとき、図示の例の如き多孔板
