Abstract

The invention discloses a raw material batch for preparing magma rock fibers and a preparation method of the magma rock fibers. The raw material batch is characterized in that the raw material batch is a raw material batch which is used for producing magma rock fibers and is prepared by uniformly mixing 50-90% of magma rock, 10-50% of gasification furnace slag and 0-30% of auxiliary raw materialsin percentage by weight and grinding the mixture until the particle size is smaller than 80 meshes; the preparation method of the magma rock fiber comprises the following steps: heating the raw material batch to 1420-1500 DEG C, melting for 7-24 hours, and drawing to obtain the magma rock fiber. With application of the method, the raw materials are rich in resource and easy to obtain, industrial solid waste gasification slag is fully utilized, waste is turned into wealth, and the production cost is reduced; the auxiliary raw materials facilitate the design of chemical components and main mineral components of the prepared magma rock fiber material, improve the melting property of the glass, are beneficial to fiber forming and wiredrawing performance improvement, are more suitable for wiredrawing operation, are convenient for large-scale stable industrial production, and are high in practicability.
