  公开号：EP1070730A2

  公开（公告）日：2001-01-24

  A resin composition primarily suitable for filling electric cable joints for service at "low" voltages (up to around 36kV) comprises a resin base consisting of at least one (meth)acrylate of an alkanol having from 6 to 20 carbon atoms (preferably isodecyl methacrylate) together with a di- or tri(meth)acrylate crosslinker in an amount of between 0.2 and 5 parts by weight per hundred parts of resin base, an initiator and at least one mineral filler; provided that where the crosslinker is present in an amount of 0.7 parts by weight per hundred parts of the resin base or more, a non-reactive solvent is present in the resin composition in an amount of 0.1 to 10 parts by weight per hundred parts of the resin base. The crosslinker is preferably a polyethylene glycol dimethacrylate and the initiator a simple peroxide. The compositions are minimally irritant, appear free of other health hazards, and are of low flammability; and they adhere well to cable-making materials, including silane-crosslinked polyethylenes.

  一种主要适用于在 "低 "电压（最高约 36kV）下填充电缆接头的树脂组合物，由至少一种具有 6 至 20 个碳原子的烷醇的(甲基)丙烯酸酯（最好是甲基丙烯酸异癸酯）与二或三(甲基)丙烯酸酯交联剂（以每百份树脂基的重量计，交联剂的用量在 0.2 至 5 份之间）以及引发剂和至少一种矿物填料组成。如果交联剂的含量为每百份树脂基 0.7 份（按重量计）或更多，则树脂组合物中的非 反应性溶剂的含量为每百份树脂基 0.1 至 10 份（按重量计）。交联剂最好是聚乙二醇二甲基丙烯酸酯，引发剂最好是简单过氧化物。 这种组合物的刺激性很小，对健康没有其他危害，可燃性也很低；它们能很好地粘附在电缆制造材料上，包括硅烷交联聚乙烯。
