Hydrophobic glass wool and preparation method thereof

The invention provides hydrophobic glass wool and a preparation method thereof, and relates to the technical field of glass wool. The hydrophobic glass wool is prepared from the raw materials such as the plate glass, the quartz sand, the borax, the feldspar, the limestone, the sodium carbonate, the dolomite, the binder, the modified water repellent and the like, the duration of the hydrophobic effect of the glass wool is remarkably prolonged through the use of the modified water repellent, and the product still has a relatively high hydrophobic rate at a high temperature; the popularization, application and industrial development of the hydrophobic glass wool are promoted. 本发明提供了一种憎水型玻璃棉及其制备方法，涉及玻璃棉技术领域。本发明的憎水型玻璃棉由平板玻璃、石英砂、硼砂、长石、石灰石、纯碱、白云石、粘结剂、改性憎水剂等原料制成，通过改性憎水剂的使用，显著延长了玻璃棉憎水效果的持续时间且产品在高温下依然具备较高的憎水率，促进了憎水型玻璃棉的推广应用与产业发展。
