Abstract
The cable sheath material comprises the following raw materials in parts by weight: 10-50 parts of main resin, wherein the main resin is selected from at least one of PVC-2500, PVC-1800, PVC-1300, PVC-1000, PVC-800 and PVC-400; 5-15 parts of auxiliary resin, wherein the auxiliary resin is at least one selected from MAH-g-EVA, MAH-g-POE, MAH-g-EPDM, EVA28%, EVA40%, EVA50% and EVA 70%; 20-70 parts of plasticizer; 5-10 parts of flame retardant which is a mixture of modified tannic acid and modified ammonium polyphosphate; 1-5 parts of stabilizer; 5-25 parts of filler; 0.1-0.5 part of antioxidant; 0.5-2 parts of lubricant; 0.5-2 parts of auxiliary agent. The cable sheath material and the preparation method thereof have reasonable formula design, low hardness, excellent rebound, fatigue resistance, flame retardant property, oil resistance, acid and alkali resistance, temperature resistance and other properties, and the comprehensive properties are superior to those of similar cable sheath silicone rubber products, so that the cable sheath needs can be better met and the service life of the cable sheath can be prolonged.
Description
Technical Field
The invention belongs to the technical field of cable jackets, and particularly relates to a cable jacket material and a preparation method thereof.
Background
The cable sheath is the outermost layer of cable, can effectual protection inside electric wire reduce the damage, extension electric wire's life. At present, some cable jackets in the prior art adopt silicon rubber, the silicon rubber is synthetic rubber with molecular chains having both inorganic and organic properties, a molecular main chain consists of silicon atoms and oxygen atoms (Si-O) alternately, and molecular side chains are organic groups such as methyl, phenyl, vinyl or trifluoropropyl and the like connected with the silicon atoms, so that the cable jackets have great advantages in the aspects of high and low temperature resistance, elasticity, physiological inertia, aging resistance, electrical insulation and the like.
The cables are classified into general cables, flame-retardant cables and fire-resistant cables according to their own combustion characteristics, and flame-retardant cables are classified into A, B, C, D flame-retardant grades according to their flame-retardant properties. The new edition of civil architecture electrical design Specification states that: the super high-rise building should select the cable with the flame retardant property B1 grade or above. Because of the low oxygen index of the silicone rubber, the silicone rubber has poor self-extinguishing property, is extremely easy to burn at high temperature and generates a large amount of toxic and harmful gases, thereby greatly limiting the further wide application of the silicone rubber in cable jackets.
In addition, the material for the cable sheath has certain requirements on rebound, fatigue resistance, oil resistance, acid and alkali resistance, temperature resistance and other performances, so as to meet the comprehensive requirements of the cable sheath and improve the overall service life of the cable.
