Desulfurized gypsum thermal-insulation material

Abstract

The invention relates to a desulfurized gypsum thermal-insulation material belonging to thermal-insulation materials. The waste pollutant desulfurized gypsum in the existing heat power plants is piled and filled in land, thereby polluting the ecological environment and influencing the safe operation of the power plants. The desulfurized gypsum thermal-insulation material provided by the invention comprises the following components in parts by weight: 80-85 parts of desulfurized building gypsum, 15-20 parts of vitrified microbead, 0.1-0.25 part of cellulose ether, 0.2-0.4 part of air entraining agent, 0.01-0.015 part of retarder and 70-100 parts of water. The components are added into water and evenly mixed to obtain the desulfurized gypsum thermal-insulation material. The desulfurized gypsum thermal-insulation material has the advantages of low coefficient of heat conductivity, thermal insulation and heat-shielding performance, energy saving, moderate strength, favorable workability and short construction cycle, has the functions of fire resistance, sound absorption, air humidity conditioning and the like, and reduces the piling and landfilling of the desulfurized waste residues as well as environmental pollution; and no CO2 is emitted in the production process.

Description

technical field [0001] The invention belongs to thermal insulation materials, in particular to a desulfurized gypsum thermal insulation material. Background technique [0002] With the development of contemporary society, energy and the environment have become important factors restricting economic development. Reducing energy consumption and protecting the living environment of human beings are major research topics for scientists all over the world. [0003] In order to provide people with a comfortable working and living environment, people use air conditioners to lower the temperature in summer; they use various heating and heating measures to increase the temperature in winter. Existing commonly used building materials have unsatisfactory heat preservation and heat insulation performance, which increases energy consumption, increases carbon dioxide emissions, and destroys the human environment. [0004] On the other hand, in order to protect the living environment of h...

Problems solved by technology

Due to the immature deep processing technology of existing desulfurized gypsum products, lack of technical standards, high processing costs, and high energy consumption, desulfurized gypsum cannot be effectively used

A large amount of desulfurized gypsum is piled up and landfilled because it cannot be digested, which pollutes the ecological environment and also affects the safe operation of the power plant
