Example Embodiment
[0016] Example 1:
[0017] Production method of hydrophobic rock wool:
[0018] (1) Raw material preparation: mix basalt, fly ash, gabbro, iron ore, bauxite, wollastonite, and melt them into a liquid mixture;
[0019] (2) Hydrophobic liquid preparation, according to weight percentage: SILRES BS 1042 0.3-0.5%, methyl cellulose 5-8%, polyacrylamide solution 1-2%, the rest is phenolic resin phase and mix well;
[0020] (3) Fiber preparation: The liquid mixture is continuously flowed into the centrifugal roller rotating at high speed, the liquid mixture is condensed into filamentous filaments under the action of centrifugal throwing and air cooling, and the filaments are collected and formed under the action of the blower. , Spray the hydrophobic liquid evenly on the rock wool fiber;
[0021] The (1) raw material components are calculated by weight percentage: basalt 10%, fly ash 25%, gabbro 1.3%, iron ore 2.7%, bauxite 25%, wollastonite 36%.
