Composite wall insulation material

Abstract

The invention discloses a composite wall insulation material, which is made from the following raw materials by weight: 12-15 parts of iron tailings, 6-7 parts of waste syrup, 8-10 parts of oil palm fiber, 5-6 parts of titanium dioxide, 5-6 parts of albite powder, 210-250 parts of sludge, 4-5 parts of Vac / E dispersible polymer powder, 2.5-3 parts of polyacrylamide, 1.7-2.4 parts of sodium lauryl sulfate, 120-130 parts of alpha-semi-hydrated gypsum, 7.1-9 parts of cement, 4-5 parts of hydrated lime, 3-4 parts of polyphenylene sulfide, 2-3 parts of molybdenum disulfide, 5.4-6.4 parts of fly ash, 4-5 parts of activated carbon, 8-9 parts of diatomaceous earth, 2-3 parts of hexamethylenetetramine and a proper amount of water.

Description

technical field [0001] The invention relates to the technical field of wall thermal insulation materials, in particular to a composite wall thermal insulation material. Background technique [0002] With my country's growing national economy and the continuous increase of urban population in recent years, my country's treatment efficiency of urban sewage is getting higher and higher, resulting in an increasing output of sludge, a by-product produced in the process of sewage treatment. The sludge produced in the sewage treatment process contains a large amount of insoluble flocs, a large amount of water, complex organic substances, and a variety of heavy metals, toxic substances, pathogenic bacteria and other harmful substances. If not treated, it will not only cause serious pollution to the environment, but also ignore the use value of these sludges, resulting in a waste of resources. The traditional sludge treatment method not only consumes a lot of resources, but also pol...

Problems solved by technology

[0003] In the patent application number 200810171725.1 "Sludge Treatment Method and Sludge Foamed Lightweight Concrete Produced by This Method and Its Application", untreated sludge and quicklime are also used to stir and react to form sludge slaked lime, which is then mixed with cement , water and foaming agent are mixed to obtain foamed lightweight concrete, which has many uses, and its performance in all aspects is better than that of ordinary concrete. However, it is not treated with waterproof and organic matter in the sludge treatment process, which is harmful to people's health. Great impact, because sludge is water-absorbent and easy to absorb external moisture. Over time, it will reduce the safety factor and endanger people's lives and property.
