[0002] A fireproof and heat-insulating sleeve refers to a sleeve-like structure prepared from fireproof and heat-insulating materials. In automotive components, the fireproof and heat-insulating sleeve is one of the common key components. It is generally wrapped around the outer periphery of automotive wires or pipelines, playing a role in fireproofing and heat insulation to ensure the normal use of the internal wires and pipelines.

[0003] After the existing fireproof and heat-insulating sleeve is sleeved on a wire or pipeline, in order to fix it, glue is often dropped to fix it. However, as the use time increases, the glue will fall off, which will affect the use stability of the fireproof and heat-insulating sleeve. Moreover, fixing with glue makes the later disassembly more difficult. In addition, the existing fireproof and heat-insulating sleeve has limited strength and durability, and its fireproof and heat-insulating performance will also weaken with the increase of use time, which will further affect safety. For this reason, we propose an enhanced aramid composite fireproof and heat-insulating sleeve. Summary of the Utility Model
