被覆電線・ケーブルの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Background and Objects of the Invention] The present invention relates to a method for manufacturing water (silane) crosslinked rubber/plastic coated electric wires/cables.
従来提案されている架橋ゴム・プラスチック被覆電線・
ケーブルの製造方法としては、電子線照射による製造方
法、過酸化物を用いた化学架橋による製造方法がある。Previously proposed cross-linked rubber, plastic-coated wires,
Cable manufacturing methods include a manufacturing method using electron beam irradiation and a manufacturing method using chemical crosslinking using peroxide.

上記各製造方法のうち、水架橋による電線・ケーブルの
製造方法は、ゴム・プラスチック層を水分に浸すことに
より常温でも架橋化が可能であり、架橋が容易であると
いうことで注目されている。On the other hand, recently, a production method using so-called water crosslinking has been industrialized, in which a hydrolyzable unsaturated silane is mixed with an organic polymer and then crosslinked with water. especially,
Among the above manufacturing methods, the method for manufacturing electric wires and cables by water crosslinking is attracting attention because crosslinking is possible even at room temperature by soaking the rubber/plastic layer in water, and crosslinking is easy.
ところで、上記水架橋による電線・ケーブルの具体的な
製造方法を見てみると、一般には次のような製造工程を
経ることによシ行われている。By the way, if we look at a specific method for manufacturing electric wires and cables using water bridges, it is generally carried out through the following manufacturing steps.

より行われている。An insulated wire is manufactured by extruding and coating a conductor with a water-crosslinking material in which a hydrolyzable unsaturated silane is mixed with an organic polymer such as polyethylene, and the insulated wire is further wound around a drum. Thereafter, the drum wrapped with the insulated wire is left in a high temperature, high humidity room for a predetermined period of time.
しかし乍ら、斯かる水架橋方式を見てみると、９ドラム
への巻層段数が多い場合、特にドラムの中心部側に位置
する絶縁電線においては水架橋するのに相当時間がかか
り、そのため架橋させる時間が実際の架橋反応時間よシ
長く要するのが現状である。However, when we look at this water bridge method, we find that when there are many winding layers on a 9-drum, it takes a considerable amount of time to water bridge, especially for insulated wires located near the center of the drum. At present, the crosslinking time is longer than the actual crosslinking reaction time.

Generally known hydrolyzable unsaturated silanes such as vinyl silane are added to polymers such as ethylene-propylene (or hasien monomer) copolymers, ethylene-butylene copolymers, or chlorinated polyethylene. A mixture is used.

幅な向上が期待できる。According to one embodiment of the present invention, the process is carried out using a drum in which a large number of through holes are formed, so that the steam in the high temperature and high humidity chamber can smoothly pass through each of the through holes provided in the drum. Since the water is evenly distributed near the insulated wire located at the center of the drum, the insulated wire can be uniformly water-crosslinked in a short time, and as a result, it is expected that the crosslinking efficiency will be significantly improved. can.
