Abstract

The invention discloses a moistureproof and flame-retardant insulated cable for instruments. The cable comprises a conductor and a sleeve tube; an insulating layer is arranged outside the conductor, and the conductor and the insulating layer which is arranged outside the conductor are arranged in the sleeve tube; a gap is provided between the sleeve tube and the insulating layer, and the gap is fully filled with an epoxy resin foaming material; the sleeve tube comprises the following components in parts by mass: 40-50 parts of EVA resin, 20-25 parts of terpolymer EP rubber, 15-25 parts of an ethylene-vinyl alcohol copolymer, 15-20 parts of colemanite, 5-7 parts of polyacrylamide, 3-4 parts of norbornane diisocyanate, 5-10 parts of calcium carbonate, 8-12 parts of glass fibre, 6-10 parts ofdecabromodiphenyl ethane, 10-15 parts of polyvinylidene fluoride, 3-7 parts of sodium dodecyl sulfate, 10-13 parts of diatomite, 1-3 parts of chlorinated paraffin, 3-8 parts of crosslinked polyvinylpyrrolidone, 5-10 parts of a fire retardant, 3-5 parts of a curing agent, 2-3 parts of a silane coupling agent, and a proper amount of deionized water. The product has good moisture prevention and flame retardation effects.

Description

technical field [0001] The invention relates to a moisture-proof and flame-retardant instrument insulated cable. Background technique [0002] The outer layer of cable insulation is mainly used to protect the inner layer wires. At present, most of them use polyvinyl chloride cable material, which is a multi-component mixed material based on PVC resin and added with various compounding agents. Because of its superior mechanical properties, good weather resistance, excellent electrical insulation properties, easy processing and low cost, it is widely used as insulation and sheath materials for wires and cables, but the cable insulation materials on the market still exist. There are many defects, some have poor moisture-proof effect and are prone to electric leakage, and some have poor flame-retardant effect and are likely to cause fire. Contents of the invention [0003] The object of the present invention is to provide a moisture-proof and flame-retardant instrument insula...
