The invention discloses a wire insulation material, comprising the following components in parts by weight: 30-50 parts of chlorinated polyethylene rubber, 10-15 parts of magnesium hydrate, 5-8 parts of a plasticizer, 3-6 parts of barium sulfate powder, 4-12 parts of ferric oxide powder, 6-15 parts of sepiolite and 5-7 parts of paraffinic oil. The flame-retardant flexible wire and cable insulating layer or a sheath composition disclosed by the invention is high in tensile strength and high in operating temperature, and can be used as a wire at 105 DEG C, and the tensile strength can be up to 12MPA. The selected halogen flame retardant is environmental friendly, does not contain a biphenyl compound, and does not release biologically harmful dioxin in combustion.
Description
technical field [0001] The invention relates to a cable insulating material, in particular to a wire insulating material. Background technique [0002] At present, wires and cables are widely used for the transmission of energy and information. The insulation layer or sheath of wires and cables made of traditional polymer materials is easy to burn due to excessive heat generation or short circuit during use, causing fire. However, many regions such as the European Union and the United States have imposed restrictions on heavy metals and biphenyl compounds in electrical appliances and wire products. When traditional halogen flame retardants burn, they release dioxins, which are harmful to organisms. Therefore, environmentally friendly wires and cables will be a development trend. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a wire insulation material with hig...
