Embodiment Construction

[0012] The industrial waste slag and alkali slag of the present invention produce a new type of light-weight wall insulation material product, which uses 100% of the waste slag and alkali slag discharged from the production of industrial alkali in the saline-alkali chemical industry as raw material, and adds materials such as polyurethane, hydrogen peroxide, chlorine remover, and reinforcing agent. Prepared by a specific technical process.

[0013] (1) Material preparation: The raw material is the industrial waste alkali residue discharged from the production of industrial alkali in the saline-alkali chemical industry, and the external materials are polyurethane, hydrogen peroxide, chlorine remover, reinforcing agent and other materials;

[0014] (2) Batching and mixing: industrial waste slag alkali slag is calculated as 100% by weight percentage, polyurethane is added as 1% by total weight, hydrogen peroxide is 0.5% by total weight, and chlorine removal agent is 0.5% by total ...

Abstract

The invention discloses a method for producing a novel spongy lightweight wall body insulation material by using industrial waste alkali residues. A wall body insulation material product with the performance comparable to wall body insulation material products prepared from cement, gypsum and coal ash is produced by utilizing 100 percent of the waste alkaline residues as raw materials, and addingpolyurethane, hydrogen peroxide, a deoxidant, a reinforcing agent and other materials. The wall body insulation material product has the characteristics of high strength, smalllight density, high water retention capacity, good insulation effect, high sound insulation ability, extremely high fire resistance, heat absorption function and moisture liberation function; the method has the advantages ofadvanced technology, low energy consumption, high added value, no secondary pollution in the production process and low production cost; in addition, the technical problems that industrial waste alkali residues cannot be treated is thoroughly solved and the technical problem of secondary environmental pollution is solved. A new technical process method has good application prospect, social benefits, environmental benefits and economic benefits.

Description

Technical field: [0001] The invention relates to a new type of wall insulation material or a new technology field of resource comprehensive utilization, in particular to a method for producing a new type of lightweight wall insulation material by using industrial waste and alkali slag. Background technique: [0002] With the economic development of my country's 40 years of reform and opening up, the large-scale saline-alkali chemical industry has advanced by leaps and bounds, resulting in a large amount of industrial waste and alkali slag discharge. The annual discharge of alkali slag in my country reaches about 80 million tons, and the utilization rate is less than 5%. 95% of them are landfilled, which seriously pollutes groundwater resources and causes environmental damage and impact. It is very important to recycle and reduce the amount of industrial waste and alkali slag. [0003] At present, there is no new technology at home and abroad to use 100% industrial waste and a...
