The present invention relates to a fireproof coating and electric wires and cables coated with the same. If a fire occurs in electrical equipment where many cables are installed, there is a risk that the cable insulation material will become fuel and the fire will spread to the cables. To prevent such situations, methods have been used to coat the cables with fire-retardant paint, but the commonly used fire-retardant paints are water-based emulsions containing flame retardants, inorganic fillers, and non-combustible fibers. It was added. However, the water-based emulsion used here is thermoplastic and melts or deforms at high temperatures, so even if it is highly flame retardant, cracks will occur in some parts of the coating when it burns. In many cases, combustion materials flow out from that part and combustion continues. An object of the present invention is to provide a fireproof coating that has excellent fireproofing properties, does not crack at high temperatures, and exhibits a stable combustion prevention effect over a long period of time, as well as electric wires and cables coated with the same. The fire protection paint of the present invention has a main composition of 9.5 to 23
Self-crosslinked acrylic resin solids content in weight%, 0.5-10
It is characterized by being composed of halogen compounds of 3% to 10% by weight, borates of 3 to 10%, inorganic fillers of 19 to 40% by weight, and noncombustible fibers of 0.3 to 6.5% by weight. The main part of the latter composition is a self-crosslinking acrylic resin of 15 to 35% by weight,
1-15% by weight of halogen compounds, 5-15% by weight of borates, 30-60% by weight of inorganic fillers and 0.5-15% by weight of borates.
It is characterized by a fireproof layer made of 10% by weight non-combustible fibers. The greatest feature of the present invention is the use of self-crosslinking acrylic resin. Self-crosslinking acrylic resin is
Unlike ordinary thermoplastic resins, it has excellent strength at high temperatures, so it does not lose its shape or crack when burned. Furthermore, by adding a halogen compound and an inorganic filler to this, a high degree of flame retardancy can be imparted. Self-crosslinking acrylic resin is mainly composed of 2-ethylhexyl acrylate, butyl acrylate, and methyl methacrylate, and if necessary, acrylic acid, acrylonitrile, and styrene are copolymerized, and further crosslinking groups such as methylolacrylamide, glycidyl methacrylate, and monochlorovinyl acetate are introduced. This is what I did. Furthermore, it is desirable to use a self-crosslinking acrylic resin that has been emulsionized using a nonionic emulsifier. Self-crosslinking acrylic resin is a binder for paint films, but it is flammable, so it is desirable to use it to a minimum.
The resin content should be in the range of 15 to 35% by weight of the dry coating weight. If it is less than 15% by weight, its function as a binder will be reduced, resulting in insufficient flexibility after being applied to the cable, and if it is more than 35% by weight, its flame retardancy will be insufficient. Examples of halogen compounds include chlorinated paraffin,
Chlorinated naphthalene, hexabromobenzene, decabromodiphenyl oxide, bisgwanidine tetrabromophthalate, 1,2,5,6,9,10
Hexabromocyclododecane, perchloropentacyclododecane, tris-β-chloroethyl phosphate, etc. are used. These may be used alone or in combination of two or more. The halogen compound functions as a flame retardant and should be used in an amount of 1 to 15% by weight of the dry coating. If the amount is less than 1% by weight, the flame retardancy will be insufficient, and if it exceeds 15% by weight, no corresponding improvement in effectiveness will be observed, and on the contrary, more harmful gases will be generated, which is not preferable. As borates, sodium borate, zinc borate,
Magnesium borate, aluminum borate, etc. are mentioned, and the appropriate amount thereof is 5 to 15% by weight of the weight of the coating after drying. If it is less than 5% by weight, the strength of the inorganic component will not be sufficient, and if it is more than 15% by weight, water resistance will be reduced. Inorganic fillers include calcium carbonate, aluminum oxide, hydrated magnesium silicate, silica,
Examples include hydrated alumina and clay. The inorganic filler forms the backbone of the fire protection paint, and the amount used should be 30 to 60% by weight of the dry coating film weight. If it is less than 30% by weight, the fire resistance will be insufficient, and if it exceeds 60% by weight, the flexibility of the coating will decrease. Noncombustible fibers include inorganic fibers such as asbestos and glass fibers, and Kynor (Nippon Kynor Co., Ltd.)
There are flame-retardant organic fibers such as products), and the appropriate amount is 0.5 to 10% by weight of the weight of the dry coating. 0.5
If it is less than 10% by weight, the reinforcing effect of the coating will not be sufficient.
If it exceeds % by weight, the viscosity of the paint will increase significantly, which will have an adverse effect on coating performance. In the present invention, if a halogen compound and an antimony compound such as antimony trioxide are used together, the flame retardant effect will be increased. Further, if necessary, various pigments, plasticizers, thickeners, wetting agents, bactericidal agents, etc. may be added. The application form of paint to electric wires and cables varies depending on the installation conditions of the electric wires and cables. Generally, it is common to apply a 2 to 3 meter long coating every 20 to 30 meters, and in this case, it will prevent the spread of fire to electric wires and cables beyond the area where the coating is applied. However, for electric wires and cables that are installed vertically or nearly vertically, it is desirable to apply the coating over the entire length.Especially when multiple wires are installed at once, a chimney effect will occur between the electric wires and cables, and the flames will spread far upwards. Full-length application is desirable. The wire/cable coating to be applied is an insulator,
The sheath may be any type of sheath, specifically polyethylene, polypropylene, polyvinyl chloride, chloroprene, butyl rubber, etc., and the effects of the present invention are particularly noticeable when the sheath is coated with an easily flammable material such as polyethylene. Next, examples of the present invention will be described together with comparative examples. Paints were prepared according to the formulations shown in each example in Table 1. Next, the 10
As shown in Figure 2, apply fire protection paint FM to the outer periphery of the coating at the rising point of a group of polyethylene coated cables (hereinafter referred to as group cable C), let it dry, and cover group cable C at this point with duct D. Ivy. Next, place a cloth soaked in gasoline at the bottom of the cable track and light it so that the flame F hits the cable directly.
A fire resistance test was conducted by burning for 20 minutes.

The cable at the bottom of the application area was only damaged, and the flame did not spread to the top. However, Comparative Examples 1 to 3
In this case, cracks occurred in the paint film, the flame moved upwards, and the flame did not go out even after the flame separated. This shows that the use of self-crosslinking acrylic resin greatly contributes to the fire protection properties of the cable. As explained above, the present invention provides a fire retardant paint and electric wires/cables that are highly resistant to the spread of fire, and the industrial value thereof is extremely large.
