Method for preparing glass wool with waterproof function

The invention discloses a method for preparing glass wool with a waterproof function. The method comprises the following concrete steps: (1) exporting broken glass after melting at a high temperature, and then fibering the broken glass by high-speed airflow at about 1800 DEG C; (2) spraying a waterproof agent on the glass fiber, so that the glass fiber is fully infiltrated; (3) blowing the glass fiber on which the waterproof agent is sprayed to a mesh belt of a settling chamber to form glass wool; (4) transmitting the glass wool to a roller to mold, and cutting according to the requirements; and (5) pressing the glass wool to a certain thickness according to the required unit weight, and putting into an oven at 200 DEG C to bake. In the manner, according to the method for preparing the glass wool with the waterproof function, water absorption can be prevented by the glass wool prepared by the method, construction in a rainy day is supported, and the glass wool can be exposed outdoors, so that the usage occasion is diverse, and limit of use is relieved.
