する作業が困難になっている。[Prior art] As a method to prevent the spread of fire in electric wires and cables,
A method of applying fire spread prevention paint to the outer periphery of the sheath has been adopted. Fire spread prevention paint is generally a water-based emulsion with organic flame retardants, inorganic fillers, noncombustible fibers, plasticizers, etc. added, and these fire spread prevention paints are applied to the outer periphery of the sheath of electric wires and cables and allowed to dry. This forms a fire spread prevention coating that adheres to the sheath. Polyethylene, vinyl, chloroprene rubber, silicone rubber, etc. are used as sheaths for electric wires and cables, but vinyl sheaths and fire-spread prevention paints are particularly sensitive (adhesive. It has become difficult to remove the protective coating.

まれる。[Problems to be Solved by the Invention] However, although the method using an alkaline aqueous solution is effective against emulsion polymers with inferior alkali resistance, it has almost no peeling effect on ordinary fire spread prevention coatings. . Further, the method using a stripping liquid mainly composed of dichloromethane has the problem that it swells the fire spread prevention coating and also swells the cable sheath. In other words, multiple wires/cables are laid in groups, and a fire spread prevention coating is provided to bundle them together, but if only some of the wires/cables in the group are removed and replaced, the entire wire/cable will be covered. After the fire spread prevention coating is peeled off, it is removed and replaced, and the fire spread prevention coating is reinstalled. In this way, when removing the fire spread prevention paint, the stripper will affect not only the wires and cables that are to be removed, but also the wires and cables that will be used afterward, so do not allow the wires and cable sheaths to swell. A release agent is desired.

The purpose of this invention is to provide a method for peeling off the fire spread prevention coating of electric wires and cables.

きるようにしたものである。Diethylene glycol monoethyl ether acetate has the function of swelling the fire spread prevention coating. This material has excellent compatibility with water and can be diluted at any ratio. Adding water to diethylene glycol monoethyl ether acetate can reduce its volatility and significantly improve its safety. However, since diethylene glycol monoethyl ether acetate aqueous systems have extremely low viscosity, it is difficult to apply the coating to the outer periphery of the fire spread prevention coating, and the amount of adhesion is small, causing problems in workability. In the present invention, in order to solve this problem, diethylene glycol monoethyl ether acetate aqueous system is
By containing an aqueous emulsion and silicic anhydride, the viscosity is increased to form a paint, which can be applied to the outer periphery of the fire spread prevention coating.

Containing 0 parts by weight increases the viscosity and makes it possible to apply with a brush.

Further, the solvent absorption rate of the vinyl sheath after the fire spread prevention coating is peeled off is 2% or less, which has 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 is easy, but since the vinyl sheath swells and softens, the tensile strength decreases significantly and the elongation increases.
