Environmentally-friendly wall insulation material

Abstract

The present invention discloses an environmentally-friendly wall insulation material, which is prepared from the following raw materials by weight: 6-8 parts of shell powder, 4-5 parts of polyvinyl alcohol, 2-3 parts of bismuth oxychloride, 3-4 parts of magnesium hydroxide, 210-250 parts of sludge, 4-5 parts of Vac / E dispersible polymer powder, 2.5-3 parts of polyacrylamide, 12-14 parts of palygorskite powder, 1.7-2.4 parts of sodium lauryl sulfate, 120-130 parts of alpha-semi-hydrated gypsum, 7.5-9 parts of cement, 5-5.6 parts of fly ash, 4-5 parts of activated carbon, 6-8 parts of sawdust powder, 4-5 parts ofalumina fiber, 2-3 parts of methylsilicone oil, 8-9 parts of diatomite, 4-5 parts of alum, 1-2 parts of white mineral oil and a proper amount of water.

Description

technical field [0001] The invention relates to the technical field of wall insulation materials, in particular to an environment-friendly wall 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 pollute...

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.
