Abstract

The invention relates to a dry preparation process of a graphite tailings-based foaming wall building block. According to the process, waste graphite tailings produced by graphite mining are used as amain raw material, and are supplemented with mineral raw materials, chemical industry raw materials and a foaming agent SiC according to a specific ratio, such that various materials are synergistically combined, and the thermal conductivity of the prepared foaming wall building block is significantly reduced, and is below 0.10 w / (m.k). Compared with the foaming building block in the prior art, the foaming wall building block of the present invention has characteristics of excellent thermal insulation performance, low bulk density, light weight and high strength, wherein the bulk density is less than 0.45 kg / m<3>, and the compressive strength can reach more than 5.12 Mpa. According to the present invention, by using the graphite tailings as the main raw material, the method has advantagesof energy saving and emission reduction, and can reduce the pollution of tailings waste to soil and environment, improve the recycling rate of solid waste, greatly reduce the production cost of building blocks, and achieve good economic benefits.

Description

technical field [0001] The invention relates to the technical field of block production, in particular to a process for producing foamed wall blocks using graphite tailings as the main raw material. [0002] technical background [0003] Graphite is an indispensable inorganic non-metallic raw material in the chemical and electrical industries, and also plays an irreplaceable role in the defense industry and high-tech products. However, after selecting graphite from graphite ore, a large amount of tailings are left, and its accumulation not only occupies a large amount of land, but also seriously pollutes the ecological environment. [0004] With the rapid development of the construction industry and the innovation of wall materials and the requirements of building energy conservation, foamed walls have been widely valued because of their characteristics. Most of the foamed wall blocks in the prior art have poor thermal insulation performance, which cannot meet the requiremen...
