The present invention relates to a self-adhesive sulfur-blocking tape with excellent sulfur-blocking performance. For electric wires and cables that are installed in locations where a large amount of sulfide is present or generated, such as chemical factories and sewage, sulfide penetrates through the anti-corrosion layer and insulating layer and reacts with the conductor copper, corroding the copper and causing dielectric breakdown. It may lead to. In order to prevent this, electric wires and cables have been proposed that use as an anti-corrosion layer a resin composition containing a lead compound that can react with sulfides.
37742, Special Publication No. 48-38157, Special Publication No. 49-20742). However, if a part of the installation site is particularly rich in sulfides, it is very uneconomical to install the above-mentioned sulfide-shielded wires and cables that have sulfide-shielding performance over the entire length, and therefore ordinary electric wires After the cable is installed, it is often necessary to add sulfur barrier properties to the connections and other necessary locations. In addition, if the above-mentioned sulfur-shielded electric wire cable must be used,
It is necessary to sulfurize the connection. Due to the above-mentioned needs, there is a need for an implementation method that can easily sulfurize electric wires, cables, and their connections on-site. The present invention was made with this point in mind, and by blending an iron compound that can react with sulfides with a self-bonding base resin containing an adhesive, etc., it is possible to remove existing electric wires and cables. The purpose of the present invention is to provide a self-fusing sulfur-blocking tape that can be easily applied to the joints of the present invention and has an excellent effect in preventing the intrusion of sulfides. The reason why the tape of the present invention is particularly self-adhesive is that when the tape is wound around an electric wire/cable, the tape winding layers self-fuse and become integrated, and from the gap between the wraps of the tape. This is because it can prevent the intrusion of sulfides. The base resin used for the above tape is:
A resin composition containing butyl rubber, ethylene-propylene copolymer, or chloroprene with a tackifier such as polyisobutylene or coumaron resin, which is uncrosslinked, or chemically crosslinked or irradiation crosslinked. A material having self-fusion properties is used. These resin compositions may contain
A softening agent such as DOP (dioctyl phthalate) or process oil may be added. Iron compounds that can react with sulfides include oxides (FeO, Fe 2 O 3 , Fe 3 O 4 ), hydroxides (Fe(OH) 2 ),
Examples include chloride (FeCl 2 ), carbonate, sulfate, and acetate, but oxides are particularly preferred because of their low cost. The blending amount of the above iron compound is as follows:
It is preferable that the iron content of the iron compound is in the range of 10 to 150 parts by weight per 100 parts by weight. The reason for this is that if the iron compound is less than 10 parts by weight, a sufficient sulfur blocking effect cannot be expected, and if it exceeds 150 parts by weight, the strength and self-fusing properties of the tape will decrease. In order to confirm the effects of the present invention, Examples and Comparative Examples of various formulations shown in Tables 1 and 2 will be compared and explained. Tapes with a thickness of 1 mm and a width of 20 mm were made from resin compositions with various formulations shown in Tables 1 and 2.
After wrapping it around a glass rod of mmφ and leaving it for 1 hour, it was cut open with tape and the self-adhesiveness was examined by checking whether the tape peeled between the wound layers. Furthermore, 50mm x 10mm x 1
After leaving a 1 mm thick tape wrapped around a 5 mm thick copper plate in a hydrogen sulfide saturated solution for a specific period of time,
Take them out one by one, cut the wrapped tape,
The state of corrosion of the copper plate was observed. The results are shown in Tables 1 and 2. As is clear from the results shown in Tables 1 and 2, the products containing the lead compounds shown in Comparative Examples 2, 3, and 5 have insufficient sulfurization performance, so they cannot be saturated.
Corrosion of the copper plate was observed within one year in the H2S solution, and comparative example 4, which contained a large amount of lead compound, had a tensile strength of 0.20.
Kg/mm 2 or less, the elongation decreases to 400% or less, making it difficult to wrap, and the self-fusion property is also poor, so the H 2 S saturated liquid easily penetrates without being integrated after wrapping. A tape with an iron content of less than 10 parts by weight, as in Comparative Example 1, is undesirable because the copper plate will corrode within one year in an H 2 S saturated solution. The tape has low tensile strength and elongation, and poor self-bonding properties. A tape that is not self-adhesive like Comparative Example 6 cannot prevent the infiltration of sulfides even if it is wound. On the other hand, the example shows sufficient tensile strength and elongation for winding, and has good self-fusion properties, so it can be completely integrated after winding. No corrosion of the copper plate was observed even after being left in the liquid for one year.
