Environment-friendly rock wool and production method thereof

Abstract

The invention provides environment-friendly rock wool. The environment-friendly rock wool is prepared from 50-60% of basalt, 8-20% of blast furnace slag, 8-20% of process waste and 0-12% of coke. Theinvention also provides a production method of the environment-friendly rock wool. The production method comprises the following steps of raw material collection, raw material smelting, centrifugal fiber forming, cotton felt forming, cotton plate forming, cutting, package, loading transportation and delivery from storage and offline processing. According to the environment-friendly rock wool and the production method of the environment-friendly rock wool, the process waste produced in the rock wool producing process is used as one of producing raw materials, the product quality is ensured, theproduction cost is also reduced, and meanwhile process waste treatment is omitted. In addition, metal slag in the production process is collected and recovered, energy is saved, produced waste gas isfiltered, environmental harm is reduced, and the prepared rock wool is good in quality, attractive and reasonable price and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of rock wool processing, in particular to an environment-friendly rock wool and a production method thereof. Background technique [0002] In recent years, fires caused by improper selection of external wall insulation materials have been shocking, causing great losses to the safety of people's lives and property. Rock wool products are internationally recognized as the "fifth conventional energy source" due to their excellent fireproof and thermal insulation properties. "The main energy-saving materials. Every ton of rock wool products used for insulation in buildings can save energy equivalent to 1 ton of oil a year, which is in line with the trend of low carbon, energy saving, and emission reduction. Therefore, as an ideal building insulation material, rock wool is facing unprecedented challenges Development opportunities and challenges. [0003] At present, the main raw materials for producing rock woo...

AI Technical Summary

Problems solved by technology

[0004] The production of rock wool by the above process requires the use of a large amount of basalt and produces a large amount of solid waste. Among them, basalt is a natural mineral raw material. The mining process is difficult and will affect the environment, thereby increasing the production cost of rock wool. In addition, rock wool A large amount of solid waste will be generated in the cotton production process, and the disposal of a large amount of solid waste requires high costs, and improper disposal will cause environmental pollution
