Ceramic polyolefin sheath material for non-metal flame-retardant fire-resistant optical cable
The invention discloses a ceramic polyolefin sheath material for a non-metal flame-retardant fire-resistant optical cable. A ceramic polyolefin sheath layer is formed by processing a ceramic polyolefin sheath material through a plastic extruding machine; the ceramic polyolefin sheath material is prepared from the following components in parts by weight: 30 to 60 parts of ethylene-vinyl acetate copolymer, 10 to 20 parts of polyethylene, 20 to 40 parts of vinyl copolymer, 8 to 15 parts of linear low density polyethylene grafted maleic anhydride, 10 to 30 parts of phosphorus-nitrogen flame retardant, 6 to 8 parts of p-dimethyl dibenzylidene sorbitol, 20 to 50 parts of glass powder, 30 to 150 parts of ceramic powder, 1 to 3 parts of amino silane, 3 to 6 parts of polyisobutene and 1 part of antioxidant. 3 parts of an ultraviolet light absorber, 0.5-1.5 parts of a lubricant, and 2-5 parts of a lubricant. The fire-resistant cable has excellent fire resistance, a small amount of smoke is released during combustion, the smoke amount is less than 80 when flames exist, the smoke amount is less than 200 when no flames exist, the visual distance is long during fire disasters, and harm to human bodies is reduced.
本发明公开了一种非金属阻燃耐火光缆用陶瓷化聚烯烃护套材料，所述陶瓷化聚烯烃护套层由陶瓷化聚烯烃护套材料通过挤塑机加工而成，所述陶瓷化聚烯烃护套材料由以下重量份的组分组成：乙烯‑醋酸乙烯共聚物30~60份、聚乙烯10~20份、乙烯基共聚物20~40份、线性低密度聚乙烯接枝马来酸酐8~15份、磷氮阻燃剂10~30份、对二甲基二亚苄基山梨醇6~8份、玻璃粉20~50份、陶瓷粉30~150份、氨基硅烷1~3份、聚异丁烯3~6份、抗氧剂1~3份、紫外线吸收剂0.5~1.5份、润滑剂2~5份。本发明耐火性能优异，在燃烧时释放烟雾量少，在有焰时发烟量小于80，无焰时发烟量小于200，火灾时可视距离长，降低对人体的伤害。
