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 equipment adaptability requirements. Strict screening must be carried out for natural basalt minerals and components, and it is difficult to prepare magmatic rock fiber materials. It is difficult to achieve large-scale and stable industrial production in the design of chemical composition and main mineral composition
[0008] In the prior art, there is no bibliographical report on the use of magmatic rock and diopside, further supplemented with auxiliary raw materials for the production of magmatic rock fiber

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.
