Description
Technical field
The present invention relates to ceramic antenna engraving technology field, specially a kind of novel flame-retardant heat-conducting polymer CABLE MATERIALS and its
Preparation method.
Background technique
Cable is usually by several or several groups of conducting wires form, and wire cable insulating and sheath are commonly called as CABLE MATERIALS with plastics,
In include a variety of kinds such as rubber, plastics, nylon, in the factory and commercial mansion of modernization, in order to maintain normally to transport
Make, it is necessary to provide the cables such as power, illumination and information, data transmission, the big portion of these cables using a large amount of various cables
Divide is that bunchy is laid in the form of tunnel, channel, vertical shaft and suspension etc..
The electric arc that is generated due to cable faults itself and the nearby fire that occurs are easy for causing cable fire, cable
After fire, the intensity of a fire is along the linear burning of cable, since the most bunchy of cable is laid with tunnel, channel, in vertical shaft, mostly limited,
Relative closure space, the heat for causing burning to release are not easy to distribute, and rear heat on fire accumulates rapidly, so that temperature is risen sharply, cause
The intensity of a fire is grown rapidly, and the dense smoke and poison gas that when cable fire generates not only pollute environment, but also jeopardize the life security of people, tunnel
Road, channel, the cable in vertical shaft, once fire rises, easily formation stack effect, temperature and cigarette can be propagated rapidly, at the same cable at
Beam is laid with, and intersection stacks, will form stereo burning, if not taking reliable fire-retardant fireproof measure, will prolong and burn entire electricity
So that control room, causes the sprawling and huge economic loss of fire, cable is giving all trades and professions and thousand for cable ditch, vertical shaft, interlayer
While family brings power and facilitates in ten thousand families, the risk of fire is also brought, we provide a kind of novel flame-retardants to lead thus
