生じている。However, in recent years, higher flame retardancy has been required, and it has become necessary to incorporate a large amount of flame retardant in order to improve flame retardancy.
しかしながら、上述の配合組成の樹脂組成物において、
難燃剤を例えば40重量部程度にまで増量すると、組成
物の耐油性、耐溶剤性が著しく低下する問題があった。However, in the resin composition having the above-mentioned composition,
When the amount of the flame retardant is increased to, for example, about 40 parts by weight, there is a problem in that the oil resistance and solvent resistance of the composition are significantly reduced.

Those in the range of 91 to 0.94 g/cd can be used. In addition, low-density polyethylene is composed of molecules with long chain branches and has a melt index of 0.1 to 1.0.
A material having a density in the range of 0.91 to 0.949/cnl is used. The mixing ratio of the linear low density polyethylene and the low density polyethylene is in the range of 1=2 to 1:6 by weight. If the amount of linear low-density polyethylene is less than this range, the oil resistance and solvent resistance of the resulting resin composition will not be improved, and if it is more than this range, the moldability of the resin composition will deteriorate, which is disadvantageous. It is.

下して不都合である。For 100,181 parts of this blend of linear low density polyethylene and low density polyethylene, ethylene-vinyl acetate copolymer or styrene-ethylene-butylene copolymer
10 to 20 parts by weight of a styrene block copolymer is blended. The ethylene-vinyl acetate copolymer preferably has a vinyl acetate (VA) content of 15 to 45% by weight and a melt index of 1 to 100. The styrene-ethylene-butylene-styrene block copolymer is a block copolymer of styrene, ethylene, and butene-1, preferably having a composition of 15 to 35% styrene gold, and a density of 0. 90~0.94g/
CD is preferred. If the amount of ethylene-vinyl acetate copolymer or styrene-ethylene-butylene-styrene block copolymer is less than 10 parts by weight, the elongation of the composition will decrease, and if it exceeds 20 parts by weight, solvent resistance and oil resistance will decrease. This is inconvenient.

Polyfunctional polymerizable heptamers such as trimethylolpropane trimethacrylate, 1,3-butylene dimethacrylate, triethylene glycol dimethacrylate, diallyl phthalate, and triallyl cyanurate are used. If the amount of the crosslinking aid added is less than 5 parts by weight, sufficient crosslinking will not be achieved and the solvent resistance will be insufficient, and if it exceeds 15 parts, the flame retardance will decrease.

After being irradiated with radiation and crosslinked, it is ready for use. After crosslinking with an electron beam, a composition having such a composition has physical properties such as a tensile strength of 1.0 to 1.8 kg/m and an elongation of 200 to 400%.

用していることによる。The flame-retardant crosslinkable resin composition having such a composition has excellent oil resistance and solvent resistance even though it contains a flame retardant in an air-cooled state. This is due to the fact that straight-cut low-density polyethylene, which has excellent oil and solvent resistance, is used as part of the pace polymer.

のとなる。Moreover, since low density polyethylene with good processability is used for the remainder of the base polymer, good processability can also be maintained. Therefore, this flame-retardant crosslinkable resin composition has excellent solvent resistance while maintaining high flame retardancy and processability.
以下、実施例を示して作用効果を明確にする。 Hereinafter, examples will be shown to clarify the effects.

For these test specimens, extrusion processability, flame retardancy, tensile strength, elongation, heat resistance, and solvent resistance were measured.

In addition, heat resistance was evaluated by leaving the test piece at 158° C. for 7 days, determining the tensile strength and elongation after being left, and comparing the results with the tensile strength and elongation of the unheated test piece, and evaluating the retention rate of each.

わかる。As is clear from the results in the attached table, when the pace polymer contains too much linear low-density polyethylene, the extrusion processability is poor, and when the low-density polyethylene is too large, the oil resistance is poor. It is also seen that when the ethylene-vinyl acetate copolymer or the styrene-ethylene-butylene-styrene block copolymer is missing (tJ), the elongation of the resin composition is insufficient.

も有するものとなる。As explained above, the flame-retardant crosslinkable resin composition of the present invention uses a blend of linear low-density polyethylene and low-density polyethylene as its base polymer, and therefore contains a large amount of flame retardant. Even if high flame retardance is imparted, it has good solvent resistance and oil resistance, and also has good moldability.
