Description
Technical field
The present invention relates to a kind of protective cover material and preparation method thereof, especially a kind of B1 grades of flame retardant cable low smoke, zero halogen second
Alkene-vinyl acetate protective cover material and preparation method, belong to field of cable technology.
Background technique
Subway, has become the most indispensable mode of transportation of city commuting, and the ranking list of China's city underground mileage is annual
Refresh and focuses on mileage quantity and the volume of the flow of passengers.End 34 cities 174 such as shared Shanghai, Beijing, Guangzhou, Shenzhen in 2017 according to statistics
Subway line 4880km is being runed, and there are also the cities such as Changzhou, Xuzhou, Nantong to build, and is up to 40 to the year two thousand twenty, at that time China
Urban track traffic total kilometrage will be more than 6000 kilometers.Transport development paces are accelerated, the increase of metro operation mileage number, drive
Such as the huge demand of subway DC traction cable, it is important that urban track traffic wire and cable will become cables manufacturing company
Business growth point.After No. 3 lines of Xi'an geothermic field in 2017 " difficult to understand triumphant event ", to subway, more stringent requirements are proposed, as fire protecting performance,
The burning of low smoke and zero halogen A class bunchy need to only be reached in the past, now unanimously recognize that the huge of fire occurs for the public place that the crowd is dense
Harmfulness needs the cable of higher burning behavior class, i.e., implements B1 grades of resistances in GB31247-2014 in subway electrical system
Fire the necessity of cable.Length, the heat release rate/total amount, production of GB31247 criterion and quantity cable fire test propagation of flame
The requirement such as cigarette rate/total amount, and be classified, in addition standard alsies specify additional information: to density flaming droplet/particle, cigarette
Gas toxicity, corrosivity are classified.In short, new standard is more scientific and reasonable to fire protection requirement, be conducive to personnel in fire
Escape.The thermoplastic non-halogen low fume fire resistant cable material that subway DC traction cable majority uses at present, is not achieved B1 grades of fire-retardant electricity
The requirement of cable.
Summary of the invention
The purpose of the present invention is reach B1 grades of fire-retardant, d1 grade burnings in GB31247-2014 for subway DC traction cable
