Special halogen-free low-smoke oxygen barrier layer material for B1-grade cable

The invention provides a special halogen-free low-smoke oxygen barrier layer material for a B1-grade cable, and belongs to the technical field of new materials. The problem of low stability in the prior art is solved. The special halogen-free low-smoke oxygen barrier material for the B1-grade cable is characterized by comprising the following components in parts by weight: 80 to 90 parts of ethylene-vinyl acetate copolymer, 10 to 20 parts of metallocene linear low density polyethylene, 20 to 30 parts of compatilizer, 200 to 400 parts of halogen-free flame retardant, 2 to 5 parts of powder surface modifier, 4 to 12 parts of lubricant and 1.5 to 4 parts of antioxidant. The halogen-free low-smoke oxygen barrier layer material special for the B1-level cable is high in stability. 本发明提供了一种B1级电缆专用无卤低烟隔氧层料，属于新材料技术领域。它解决了现有技术存在着稳定性差的问题。本B1级电缆专用无卤低烟隔氧层料，其特征在于，包括以下组份：乙烯-醋酸乙烯酯共聚物：80-90份，茂金属线性低密度聚乙烯：10-20份，相容剂：20-30份，无卤阻燃剂：200-400份，粉体表面改性剂：2-5份，润滑剂：4-12份，抗氧剂：1.5-4份。本B1级电缆专用无卤低烟隔氧层料稳定性高。
