Problems solved by technology

[0007] In the prior art, the raw materials of magmatic rock fiber are mainly basalt and andesite. At present, there are still some problems to be solved urgently in the production of continuous basalt fiber, such as poor thermal permeability of pure natural basalt melt, high crystallization upper limit temperature and easy crystallization. Therefore, the basalt fiber production process has technical difficulties such as difficult fiber formation, strict process control conditions, and high equipmen

Abstract

The invention discloses a raw material batch for producing 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 batch which is prepared by uniformly mixing 50-90% of magma rock, 10-50% of diopside and 0-10% of auxiliary raw materials in percentage by weight and grinding until the particle size is less than80 meshes; and heating the batch to 1420-1520 DEG C, melting for 5-24 hours, and drawing to obtain the magma rock fibers. With application of the method, the raw materials are rich in resource, high in utilization rate, easy to obtain and low in production cost, and chemical components and main mineral components of the prepared magma rock fiber material are conveniently designed; diopside ingredients can also reduce the melting temperature of magma rock and save energy; meanwhile, the crystallization upper limit temperature in magma rock fiber production can be controlled, the glass melting material property is improved, fiber forming is facilitated, the wiredrawing performance is improved, the method is more suitable for wiredrawing operation, and large-scale stable industrial productionis facilitated.

Description

technical field [0001] The invention belongs to inorganic non-metal material magma rock fiber and its preparation, and relates to a raw material batch for producing magma rock fiber and a preparation method of magma rock fiber. It is especially suitable for the industrial production of magmatic rock fibers. Magma rock fiber is an inorganic non-metallic material with excellent performance and green environmental protection, which can be widely used in fiber reinforced composite materials, friction materials, heat insulation materials, high temperature filter fabrics and protection, shipbuilding, automobiles, water conservancy and hydropower, road traffic, national defense Military and other fields. Background technique [0002] Magmatic rock, also known as igneous rock, is a rock formed by magma ejected from the surface or intruded into the crust to cool and solidify. It is the main rock that makes up the crust, accounting for about 65% of the total volume of the crust and 9...
