Abstract

The invention discloses a production method of hydrophobic mineral wool. The production method is characterized by comprising the following steps of 1, raw material blending: mixing graystone, fly ash, gabbro, iron ore, bauxite and wollastonite and melting the mixture to obtain a liquid mixture, 2, hydrophobic liquid preparation: mixing 0.3-0.5wt% of SILRES BS 1042, 5-8wt% of methyl cellulose, 1-2wt% of a polyacrylamide solution and the balance phenolic resin to obtain a uniform mixture, and 3, fiber preparation: continuously feeding the liquid mixture into a centrifugal roll in a high-speed rotation state so that the liquid mixture is coagulated to form fibers under the action of centrifugal throwing and air cooling and then the fibers are collected and molded under the action of blower air-blasting, and spraying the hydrophobic liquid to mineral wool fibers. The hydrophobic mineral wool comprises, by weight, 10-20% of graystone, 14-30% of fly ash, 2.8-6.8% of gabbro, 1.2-6.2% of iron ore, 20-35% of bauxite and 25-45% of wollastonite.
