Novel insulating arc extinguishing tube and production process thereof

The invention is suitable for the technical field of fuse tube production, and provides a novel insulating arc extinguishing tube which comprises the following raw materials in percentage by weight: 64%-71% of multi-axial stitch-bonded aramid yarn, 11.5%-14% of arc extinguishing resin, 10%-11.7% of a curing agent, 4.5%-6.2% of a diluent, 2%-2.6% of an accelerant and 1%-1.5% of filler. The invention also discloses a production process of the novel insulating arc extinguishing tube. The fuse tube produced by the invention not only has the characteristic of extremely low water absorption, but also has good insulativity, arc extinguishing property and mechanical strength, the problems that the fuse tube is layered after being exposed in air for a long time, the insulating strength becomes low and the like are fundamentally solved, the production period is shortened to 2 days from the original one month, the yield is greatly improved, the operation is easy, and the production cost is reduced. And the yield is also
