A method of applying a fire spread prevention coating to the outer circumference of the sheath has been adopted. In general, fire spread prevention paints are based on an aqueous emulsion with organic flame retardants, inorganic fillers, noncombustible fibers, plasticizers, etc. applied, and these fire spread prevention paints are applied to the outer circumference of the electric wire / cable sheath and dried. When this is done, a fire spread prevention coating adhered to the sheath is formed. Polyethylene, vinyl, chloroprene rubber, silicone rubber, etc. are used for the sheath of electric wires / cables, and especially the vinyl sheath and the fire spread prevention paint adhere well. For this reason, it is difficult to remove the fire spread prevention coating when removing the electric wire or cable.

まれる。[Problems to be Solved by the Invention] However, the method using an alkaline aqueous solution is effective for some emulsion polymers having poor alkali resistance, but has little peeling effect for ordinary fire spread prevention coatings. . Further, the method using a stripping solution containing dichloromethane as a main material has a problem that the fire spread prevention coating is swollen and the cable sheath is also swollen. That is, multiple wires / cables are laid as a group, and a fire spread prevention coating is provided for all of them, but if only some of the wires / cables in the group are removed or replaced, the entire fire spread After the protective coating is peeled off, the protective coating is removed and replaced, and the fire spread protective coating is provided again. In this way, when peeling off the fire spread prevention paint, the peeling liquid will affect not only the electric wires / cables to be removed but also the electric wires / cables to be used thereafter, so that the electric wire / cable sheath will not swell. A release agent is desired.

きるようにしたものである。Diethylene glycol monoethyl ether acetate has a function of swelling the fire spread prevention coating. This product has excellent compatibility with water and can be diluted at any ratio. By adding water to diethylene glycol monoethyl ether acetate, its volatility can be lowered and safety can be greatly improved. However, since the viscosity of diethylene glycol monoethyl ether acetate to water is extremely low, it is difficult to apply a brush when it is provided on the outer periphery of the flame spread prevention coating, and the adhesion amount is small, which causes a problem in workability. In order to solve this in the present invention, diethylene glycol monoethyl ether acetate-water system,
By adding an aqueous emulsion and silicic acid anhydride, the viscosity is increased to form a paint, which can be applied to the outer periphery of the fire spread prevention coating.

It was dried for 20 hours to give a fire spread prevention coating. Next, as shown in Table 2, four kinds of release agents a, b, c, d were prepared, and these release agents were applied by brush coating on the outer periphery of the fire spread prevention coating of the cable. The coating amount was 14 g per 20 cm of cable length.

強さは大幅に低下し、逆に伸びが大きくなる。 As is clear from Table 3, in the case of a release agent using diethylene glycol monoethyl ether acetate,
The peeling could be easily performed after 24 hours. Also, the solvent absorption rate of the vinyl sheath after peeling off the fire spread prevention coating is 2
% Or less, there is almost no effect on the vinyl sheath, and the decrease in tensile strength and elongation is extremely small. On the other hand, when dichloromethane is used (comparative example), peeling can be easily performed, but the vinyl sheath is swollen and softened, so that the tensile strength is significantly reduced and the elongation is increased.
