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.

Description

technical field [0001] The invention relates to a production method of mineral rock wool, in particular to a novel production method of water-repellent mineral rock wool. Background technique [0002] Rock wool, also known as rock wool, is a kind of mineral wool. Fluffy short fibers made from natural rocks and minerals. It is an inorganic fiber made of natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc., which are melted and fibrillated at high temperature. The natural rock, ore and other raw materials are melted in a cupola or other pool kiln (temperature below 2000 ℃), blown and quenched into a fibrous shape with a pressure of 50 atmospheres. Or use the spinning method to drop the molten liquid flow on the multi-stage rotary rotor, and spin it into fibers by centrifugal force. According to the use temperature, it can be divided into ordinary rock wool (less than 900°C); high temperature rock wool (less than 900°C). High-quality rock wool can withsta...
