<p>A basalt fiber and a basalt fiber core, a functional coating method thereof and an article weaved by the basalt fiber and a basalt fiber core are provided to coat the basalt fiber by using the fluorine group coating solution, thereby enhancing the weaving property. A basalt fiber of 1-2m/minute is passed into the coating process solution having the fluorine group coating solution as the main component and maintained by the temperature of 20-25 degrees celsius so that the surface of the basalt fiber is coated. The coating process solution consists of 50-60wt% of PTFE, 2-5wt% of non-ionic group surfactant and the remaining wt% of water. The basalt fiber is heated by temperature of 380-420 degrees celsius before the coating process. Thereafter, the basalt fiber is dried at the temperature of 80-110 degrees celsius. The dried basalt fiber is heated at the temperature of 180-270 degrees celsius. Thereafter, the heated basalt fiber is sintered at the temperature of 360-420 degrees celsius.</p> |
