Problems solved by technology

However, in the prior art, due to technical limitations, electrolytic manganese slag is rarely used as a raw material for building blocks
Therefore, the existing building block manufacturing technology has the disadvantage that electrolytic manganese slag cannot be used as building materials, and the existing building blocks, especially hollow blocks, also have the problem of unsatisfactory thermal insulation effect.

Abstract

The invention discloses a foamed plastic-electrolytic manganese slag compound insulation block and a preparation method thereof. The preparation method comprises the following steps: preparing a composite material for an electrolytic manganese slag hollow building block 1 by adding raw materials consisting of 20-40 weight portions of electrolytic manganese slag, 10-30 weight portions of cement, 20-50 weight portions of sand, 0.5-1.8 weight portions of quicklime, and 0.1-0.5 weight portions of gypsum in water with the ratio of raw materials to water of 0.45 to 0.85 and mixing; preparing the composite material into the electrolytic manganese slag hollow building block 1 with mould casting; and then filling foamed plastic core 2 in the hollow of the electrolytic manganese slag hollow building block 1 with mechanical extrusion or casting to obtain the foamed plastic-electrolytic manganese slag compound insulation block. The invention has the advantages of effectively and extensively using electrolytic manganese slag, reducing environmental pollution, reducing wasting of resource, and changing waste into valuables, and has the advantages of low cost and good heat-insulation effect of the product, and the like.

Description

technical field [0001] The invention relates to a foamed plastic and electrolytic manganese slag composite thermal insulation block and a preparation method thereof, belonging to the technical field of building block production. Background technique [0002] Electrolytic manganese slag is the solid waste left after rhodochrosite is treated with sulfuric acid solution to produce manganese metal. The concentration of sulfate, ammonia nitrogen and manganese is extremely high. The discharge of electrolytic manganese slag is relatively large, and every ton of manganese produced will produce 6-10 tons of manganese slag. At present, there are more than 50 million tons of electrolytic manganese slag in my country, and the amount is increasing by more than 10 million tons per year. The stacking and disposal of electrolytic manganese slag increases the cost of enterprises and consumes land resources. Due to long-term stacking, some harmful elements penetrate into the surface and grou...
