Rock wool produced by using phosphorous slag and preparation method thereof

Abstract

The invention discloses a rock wool produced by using phosphorous slag and a preparation method thereof, the rock wool is prepared by phosphorous slag as main raw material and dolomite and bauxite both as auxiliary raw material, wherein the proportions of the raw materials by weight part are calculated as below: 60-85 parts of phosphorous slag, 1-8 parts of dolomite and 10-25 parts of bauxite. Compared with the current method for producing rock wool with natural volcanic rock or volcano metamorphic rock, the method according to the invention realizes the production of the rock wool by using the phosphorous slag as raw material, which not only settles the raw material problem about rock wool heat-preserving material during the production in regions without natural volcanic rock or volcano metamorphic rock, but also widens the comprehensive utilization scope of industrial solid wastes such as the phosphorous slag and the like; adopting the method can effectively utilize the phosphorous slag and other industrial solid wastes to develop novel product with high added value, conforming to the requirements of policies related to cyclic economy as well as energy conservation and pollution reduction, and simultaneously achieving excellent development prospect. The rock wool produced according to the method has the advantages of good fireproof and heat preservation performance, long use time and the like, and is particularly suitable for the use as heat preservation material in the industries such as heat preservation of building energy-saving wall, chemical industry, building material, etc.

Description

technical field [0001] The invention relates to rock wool produced by using phosphorus slag and a preparation method thereof, belonging to the technical field of rock wool production. Background technique [0002] Rock wool is a commonly used thermal insulation material in the chemical industry, building materials and other industries, and can be made into rock wool sandwich composite energy-saving wall panels, which are widely used in buildings. Its traditional production method uses volcanic rocks such as basalt and granite or volcanic metamorphic rocks as the main raw materials for production. Since volcanic rocks or volcanic metamorphic rocks are distributed in relatively few areas in my country, resources are relatively scarce, which undoubtedly limits the promotion and use of rock wool insulation materials, and also has certain damage to land resources. Therefore the existing production method of producing rock wool is still not ideal enough. Contents of the inventi...
