Abstract
The invention discloses a high-temperature-resistant insulating material for a cable. The insulating material comprises the following components in parts by weight: 60 to 80 parts of ethylene propylene rubber, 1 to 10 parts of polyethylene glycol, 5 to 10 parts of aluminum hydroxide, 10 to 20 parts of chloroplatinic acid, 8 to 15 parts of a plasticizer, 3 to 10 parts of a flame retardant and 2 to 10 parts of a lubricant, wherein a stabilizer and an antioxidant are further added into the high-temperature-resistant insulating material for the cable. The produced high-temperature-resistant insulating material for the cable is high in physical performance, stable in size and low in shrinkage rate, the stretching strength, the tear strength and the resilience of the product are all greatly improved, and power can also be smoothly supplied for a certain time to win time for evacuation and rescue in case of fire.
Description
Technical field
The present invention relates to a kind of insulating material, particularly a kind of Pyrotenax insulating material.
Background technology
The fire-resistant cable that refers to is when presence of fire, still can ensure the class cable that circuit is complete, this cable, when high temperature of fire, can ensure that cable continues normally to provide electric power and the various signal of transmission in a long time, thus be that control fire and lifesaving provide safeguard.
According to the difference of refractory materials used, existing flame resistant cable is divided into mica tape flame resistant cable and mineral insulation flame resistant cable two class.It is 95-1000 DEG C of refractory standard that this two classes flame resistant cable can both reach test temperature, and during guarantee fire, circuit is complete, but these two kinds of cable qualitys are large, and production rate is slow, and cost is high.The common method of silicon rubber flame-retardant adds fire retardant in superpolymer; to reduce combustionmaterial surface temperature; dilution combustiblematerials molecular conecentration; cut off the supply of oxygen; barrier layer is formed at silicon rubber burning surface; heat energy is stoped to transmit to silicon rubber depth; suppress temperature to raise and reach fire-retardant object; but the cable that flame retardant rubber is made can only delay rubber is burnt till the time of powder; if continue to be burnt; rubber just becomes powdery gradually and comes off, and loses provide protection, and electric wire is by breakdown and cause short circuit.
At present, obviously there is following problems in domestic cable insulation material, and oxidation inhibitor can not fully melt, and has a strong impact on electrical property.Cable quality improves, and is that industry is pursued always.Especially, for public arena or the important place of the densely populated place such as theater, subway, airport, Nuclear power plants, the high temperature resistant resistivity against fire of cable just seems extremely important.
Summary of the invention
The object of the present invention is to provide a kind of Pyrotenax insulating material, can make that cable fire-proof is high temperature resistant, cost is low and intensity is high.
For reaching this object, the present invention adopts following technical scheme:
