Foaming heat preserving material and production method thereof

Abstract

The invention discloses a foaming heat preserving material and a production method thereof. The method comprises the following steps: (1) absorbing sulfur dioxide and nitrogen oxide in smoke by adopting an ozone and smoke absorbent wet method, thereby forming smoke absorption slurry, wherein the smoke absorbent is slurry formed by magnesium oxide and industrial waste water; (2) mixing the smoke absorption slurry, industrial solid waste, magnesium oxide and additives to form mixed slurry, wherein a weight ratio of the smoke absorption slurry, industrial solid waste, magnesium oxide and additives is (50 to 80) to (70 to 120) to (15 to 60) to (0.5 to 15); (3) uniformly mixing the mixed slurry and a foaming agent, then pouring, molding and maintaining, and forming a foaming heat preserving material. By adopting the production method of the invention, sulfur dioxide and / or nitrogen oxide in the smoke can be removed, and the industrial waste water and solid waste can be utilized, so that theindustrial pollution integrated treatment can be realized.

Description

technical field [0001] The invention relates to a foam insulation material and a production method thereof, in particular to a method of directly using smoke absorbing slurry to produce foam insulation materials, and the foam insulation material obtained therefrom. Background technique [0002] At present, the energy consumption of countries in the world is getting higher and higher, but it is difficult for energy production and supply to increase substantially. Therefore, energy saving work is a long-term and arduous task. Building energy conservation is an important part of the entire energy conservation work, and the key to building energy conservation lies in the use of thermal insulation materials. Therefore, research on thermal insulation materials is very important. [0003] Insulation material is a material that slows down the rate of heat flow generated by conduction, convection, and radiation. Thermal insulation materials can be divided into organic thermal insu...

Problems solved by technology

The calcination process of cement will produce a large amount of carbon disulfide and carbon dioxide, which will cause serious pollution to the environment

[0005] In addition, solid waste pollution is one of the top ten environmental problems in the world, and industrial solid waste is the solid waste with the largest discharge volume. If these industrial waste residues cannot be effectively treated and utilized, the problem of solid waste pollution cannot be fundamentally solved.
