Description
Technical field
The present invention relates to CABLE MATERIALS technical field, specifically a kind of fireproofing cable material without halide.
Background technology
Cable is the indispensable integral part of modern people life each side, and along with the frequent generation of electrical fire accident, the fire-retardant problem of electric wire causes the attention of countries in the world gradually.Because the material of cable insulation is generally macromolecular material, having combustibility, in order to prevent cable to catch fire, must improve the flame retardant properties of CABLE MATERIALS, is generally in macromolecular material, add certain fire retardant.Fire retardant great majority at present for polyolefins are halogen flame system, good flame retardation effect, cost performance high but its burning time discharge a large amount of smog and poisonous, corrosive gas, environment and human body are caused serious injury, is easy in fire process cause danger people occurring and suffocates.
Summary of the invention
Therefore, for solving the problem, the invention provides flame retardant properties high, low cigarette during burning, the fire-resistant cable material of Halogen.
The technical solution used in the present invention is: a kind of fireproofing cable material without halide, comprises the raw material of following weight part:
Base-material: 100 parts
Lubricant: 1 ~ 4 part
Inorganic combustion inhibitor: 60 ~ 80 parts
Fire retarding synergist: 5 ~ 10 parts,
Oxidation inhibitor: 1 ~ 3 part
Coupling agent: 0.5 ~ 4 part
Compatilizer: 2-10 part,
Described base-material contains ethylene-vinyl acetate copolymer 60 ~ 70 parts, linear low density polyethylene, 30 ~ 40 parts.
Further, described lubricant is selected from one or more in stearic acid, stearate, silicone grease, silicone oil, paraffin.Better can realize the consistency between inorganic combustion inhibitor and base-material and other compositions, thus solve mixing, to extrude difficulty problem.
Further, described inorganic combustion inhibitor is at least one in aluminium hydroxide, magnesium hydroxide, zinc borate, calcium carbonate.Magnesium hydroxide, as fire retardant, can not produce objectionable impurities when burning, and its resolvent can absorb the obnoxious flavour and smog that burn and produce in a large number while fire-retardant, makes CABLE MATERIALS have good flame retardant effect.Calcium carbonate is as fire retardant, and the calcium oxide produced when burning is attached to base-material top layer, stops the burning of cable, and the carbonic acid gas of generation stops cable to contact with air, plays fire-retardant effect.
Further, described fire retarding synergist is phosphor nitrogen combustion inhibitor or zinc borate, can improve processing characteristics and self-extinguishment.Can crystal water be discharged when zinc borate is heated to more than 300 DEG C, absorb heat, thus suppress combustion reactions, make the flame retardant effect of cable more remarkable.
Further, described oxidation inhibitor is 4, one or more in 4 '-thiobis-(the 6-tertiary butyl-3-methylphenol), Tyox B, 7-hydroxyl-6,8-dimethoxy benzo pyran-2-one, amine system antioxidant.Oxidation inhibitor plays antioxygenation, improves the heat aging property of product, increases the service life.
Further, described coupling agent is one or more in silane coupling agent, titanate coupling agent, peroxidation two alkane.By the effect of coupling agent and compatilizer, CABLE MATERIALS is made to have good processing characteristics and low-smoke and flame retardant performance.
Further, above-mentioned fireproofing cable material without halide, also comprises the softening agent of 10-15 part, and described softening agent is paraffin and/or trioctyl trimellitate, can be used to the plasticity improving material, to reach good processing characteristics.
Further, described compatilizer is one or both in ethylene-octene copolymer grafted maleic anhydride, Research of Grafting Malaic Anhydride Onto Polyethylene, ethylene-vinyl acetate copolymer grafted maleic anhydride, and inorganic materials can be made compatible with organic materials.
The invention has the beneficial effects as follows: constitutive material formula of the present invention is reasonable, and flame retardant properties is high, LSZH during burning.Adopt most halogen-free flameproof auxiliary agent, effectively can reduce smog, the effect of coupling agent and compatilizer, oxidation inhibitor, fire retarding synergist, this fireproofing cable material without halide is made to have good processing characteristics and low-smoke self-extinguishing performance, between each composition, there is good synergy equally simultaneously, product ageing resistance and work-ing life can be improved, the needs of actual production can be met.
